Apache Roller - Blog integration
Hi, not sure if I should post this in Apache Roller or Wicket; but is there any way to integrate Apache ROller and Wicket? ..are there any good blog engines with Wicket, or perhaps Some blog components within Wicket? Frankly I like ROllers feature set and I doubt wicket itself would have a full fledged blogging engine, though worth asking about possibilities ideas!? thanks!

How to override container markup package loaction?
How does one override container markup package loaction? If I provide mysite.wicket.pages for my Java Wicket components, then the html markup must be in the same package.

Re: How to override container markup package loaction?
Hey Ernesto, so I tried that. Application.getResourceSettings().addResourceFolder(xxx) only works for resources. So if I have a (Page A) extends (Page B). Then only the markup of Page A comes; Wicket does not seem to respect Markup Inheritance etc. when adding as resource. My fear is that the PAGE may have to be part of classpath (in /WEB-INF/classes) ..and thats not where i want my HTML / Dynamic Markup to live :( Help! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-override-container-markup-package-loaction-tp2274647p2276001.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to override container markup package loaction?
Ernest, Igor -- thanks!
I had gone to that wiki earlier; I only focussed on the section that talked
about Wicket 1.3 (which only allows to change location in Classpath) so I
missed the point. I saw 1.2 and modified the code to pick up any file from
the ServletContext; and it works with the code as follows:
public ResourceStreamLocator getFileResourceStreamLocator(final
ServletContext sc) {
final IResourceStreamLocator defaultLocator =
super.getResourceSettings().getResourceStreamLocator();
return new ResourceStreamLocator(){
@Override
public IResourceStream locate(final Class? clazz, final String
path) {
String fullPath = /html + path.replaceFirst(Your
base package
name for WebPage components, ); //TODO: Cleanup!
log.debug([getFileResourceStreamLocator.locate] fullPath =
+ fullPath);
try {
final URL url = sc.getResource(fullPath);
if (url != null) {
return new UrlResourceStream(url);
}
} catch(MalformedURLException e) { }
return defaultLocator.locate(clazz, path); //Use default
locator
}
};
}
I also had a typo in the package name of my templates :) :p
(I'm using Markup inheritance; so my templates are put in another package.
Due to the typo of that package name, Wicket was unable to locate the
templates and causing issues).
All fixed. Thanks to your posts I went back and realized my mistakes.

Single inheritence in parts
Hi, all the examples etc suggest that Single inheritence is possible but I cant break it up. The break up is essential when you want to merge common parts of your MARKUP with multiple specific parts of the Child page. Example: HTML HEADtitleBASE TEMPLATE / PARENT PAGE/title/HEAD BODY wicket:child / br / h2Some other Html common/h2 wicket:child / /BODY /HTML --- HTML HEADtitleCHILD PAGE 1/title/HEAD BODY wicket:extend Part 1 specific to Child Page /wicket:extend Any HTML here can be ignored as conceptually anyway what appears in extend is what should be rendered from a child page. wicket:extend Part 2 Specific to Child Page (will appear after common HTML in parent page) /wicket:extend /BODY /HTML I tried this, only the first part renders. I'm wondering if we can add such capability. Conceptually I don't see why not. If already possible do let me know or consider as a feature request?! -Thanks Arjun -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Single-inheritence-in-parts-tp2278064p2278064.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: UI Layout
Hi bro, so I need to change page layout markup file( since markup files will have my panels defines) 1. Use Inheritance: What I like about inheritance is you can template and further sub-template without a single line of Java (except for empty class files to represent the page ..I have a solution for this also.. read on). (There is some debate on improving inheritance http://apache-wicket.1842946.n4.nabble.com/Single-inheritence-in-parts-td2278064.html#a2278064; but lets skip that) layouts change just a little bit on every page, so having 100-200 different layout files is crazy -- With good designed templates this should be avoidable. And if not, panels can be used. 2. I need to change page layout markup file (since markup files will have my panels defines) -- So, you dont need to use PANEL's only. As explained above I believe inheritance is powerful where there is a lot of common stuff. The dynamic stuff like news, article, navigation are panels that too embedded inside the template. So the combination should reduce your combinatorial explosion! 3. Ah regarding Class files: Well this is something bothering me as well. I'm looking at CGLIB byte code generation to read the file system for markup files and auto generate java classes into the ClassLoader. So there is no need to write dumb classes. ..but this is work in progress. Just sharing the idea if anyone can beat me to it :) Please note that Im relatively new to wicket too, but through my initial frustrating experiences I learnt somethings that i hope will help you. If not, am sure the more experienced guys here will be providing valuable input. -good luck! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/UI-Layout-tp1891867p2288432.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: UI Layout
ok, so you mention wicket:id as if its some constant thing. Conceptually a markup tahhed by wicket-id, is no less powerful than injecting a scriptlet or any dynamic script you inject via JSP, PHP. Its like a reference point/range. Who says that anything between that wicket:id condemns you to the markup there? Thats what components are for. There are plenty of bases level components for you to choose, override and customize. SO once we've go through inheritance, panels the 2% that us not templatizable and falls under dynamic category will surely be replacable by some component. I'd recommend you read up on available components. I think this is an issue of perception that anything between wicket:id is static! Mabe Im wrong in understanding your real problem but I'd simply say there isnt anything you can do with JSP, JSTL, PHP that you can do with wicket! ..ok a bold statement :p Guys mack me up! haha kidding. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/UI-Layout-tp1891867p2288872.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Models and panel updates
Help me understand this, An AjaxBased components send update events as
they change!
That means except for SAVE having to save the data in one ajax request you
dont need the other fields being AJAX based. See onAfterRender() this is
able to give you the updated value as it happens:
public ProductPanel(String id) {
super(id);
setOutputMarkupId(true);
add(new Label(id));
//add(new Label(cost));
AjaxEditableLabel costLabel = new
AjaxEditableLabelString(cost) {
@Override
public void onEdit(AjaxRequestTarget target) {
super.onEdit(target); //Does the whole convert
to text box magic
Float cost =
(Float)getDefaultModel().getObject();
log.info([ProductPanel.AjaxEditableLabel.onEdit] cost prior to update =
+ cost);
}
@Override
public void onAfterRender() {
super.onAfterRender();
Float cost =
(Float)getDefaultModel().getObject();
log.info([ProductPanel.AjaxEditableLabel.onAfterRender] cost after
update = + cost);
}
};
add(costLabel); //Updatable label
add(new AjaxLinkString(save) { //But are we saving for??
All the other
fields are already AJAX based and sending updates!
@Override
public void onClick(AjaxRequestTarget target) {
log.info(saving product );
//Line below gives -- WicketMessage: No get
method defined for class:
class arjun.learning.data.Product expression: save
Product model =
(Product)getDefaultModel().getObject(); //Will give
ERROR :(
log.info([ProductPanel.AjaxLink.onClick] cost
= + model.getCost());
}
});
}
..The model is updated on changing the value of the cost field itself.
Also, its perfectly understandable why the Model is not marshaling
(becausethere are fields other than the domain object , and obviously the
CompoundPropertyModel doesn't know the difference between a Domain Model
field and a field added to the panel for display. They are all part of the
model, some of which not in your domain model.
..So where am I missing the point? :)

How to autogenerate WebPage classes for static pages?
Hi, a section of my website is static pages (template) but no need of injecting any components [I prefer getting as much dine through inheritance cleanly over Panels]. Each markup has to have a corresponding WebPage in wicket. I'm exploring the ASM library with CGLIB to auto generate classes for static templates ...is there any wicket way of doing this already? ..or if someone has a Wicket way or even the CGLIB/JAVASSIST/ASM code ready to go, I'd appreciate it. thanks -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-autogenerate-WebPage-classes-for-static-pages-tp2298749p2298749.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to autogenerate WebPage classes for static pages?
Hi Martin,
thanks. the tip was insightful. though am confused about one point.
So the examples load resources via WebApplication. While your suggestion
seems to point towards WebPage. As in the code below, I've inserted the
MARKUP of the child page ..but then that is no inheritance. Is this what you
meant or something else?
/**
* Principlebr /
* Represent All generic Static pages (in a template) without the need to
build

* This class will intercept the actual intended path

* Note: The page extends TemplatePage which defines a common template for

Re: Passing raw value to html
Lots of dynamic stuff?
If you have lots of dynamic stuff you can use a texttemplate to interpolate
your variables with it works really smooth, heres an example:
...
HashMap variables = new HashMap();
variables.put(alert, helloworld);
TextTemplate textTemplate=new TextTemplate();
textTemplate.interpolate(variables);
String js= textTemplate.asString();
…
corrosponding java script, notice the template signature ${…}
alert(${alert});
So above code will produce a javascript string ‘alert(“hello world”)’ very
useful.
Thats in the first link I showed you; helps you put variables in
whatever markup you want. Am sure there are other approaches also, but have
a look before you think its not meant for you.

Re: Integrating Wicket with Dojo/Jquery/Dwr/Ext Js
This is more a question than an opinion. Wicket is a View first framework, and also has the cleanest separation between Markups and Code that I have seen so far. I think What Scripting technology one uses should anyway never be tightly coupled with whats on the server. I keep seeing questions on Mobile device, JQuery etc. In design people should just focus on bare minimal to connect the two and avoid strong coupling. (just enough to trigger events and pass data) So in a way questions specific to How wicket supports mobile devices, or XYZ Scripting framework in the markup are not really relevant.

AutoLinkResolver WARNINGS
Hi,I have my markups in another folder and am mounting static pages via a

The Static pages are in a Common template, that uses a common menu to
navigate and uses wicket:link to get the correct link from Wicket.
Works great; except I see the following in the log, which concerns me. I'd
like to suppress the cause of the log:

Re: AutoLinkResolver WARNINGS
Maybe related; but my real issue was different. So I was mounting pages on a different path. It seems wicket:link uses that AutoLinkResolver stuff and does not keep up with mount changes. So it was not able to resolve the links on my Markup due to the changed mount points resource locator changes (in WebAppplication) Am not sure if this is a bug, but if I make changes in my mount's in WebApplication, I'd expect wicket:link to keep up.

Intercept Wicket Parsing
Hi, I want to understand how to intercept the Wicket markup Parser *in a clean way* I'm aware of org.apache.wicket.markup package. There is XMLPullParser, MarkupParser, Filter. I like the look of using Markup but surprisingly the WicketFilter directly uses XMLPullParser (looks more like a hack than a clean approach). So a good way to explain it would be a example code for something like: Default Content. To make it work one needs a label or component called component supplying the model to render the content. But, say we want to intercept this so that if no component is available the default markup shows else it picks it from a DataSource. NOTE: The Use Case here is a weak example, I really don't care about the Use case itself but more about how to use a parser to solve an example as above. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Intercept-Wicket-Parsing-tp2536131p2536131.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Java in CMS arena,..wicket to lead the way?!
Summary:: This conversation is about Java in the CMS space, comparison to PHP and is there a future to reduce turn around time with Java. Are we as a community too elitist to be stuck on masturbating on frameworks rather than solutions that affect direct outcome? ..and then technically I've centered this around Brix wicket. Hi, I've been exploring lot of Java CMS solutions and also frameworks. BRIX, Alfresco I feel are good for different reasons. From a Web framework point of view, I feel Wicket I guess Sling cut the mark pretty well (not much experience yet with Sling). However, with Java Community the solutions (beyond framework) finish is not comparable to the likes of PHP giants like Drupal, Wordpress etc. I operate in the small business market a lot , and this really hurts. I really feel the Java. With earlier version of Java it would get tedious and too boilerplate to produce anything quickly fast. But with the advent of scripting languages galore, be it Server JavaScript, Groovy, Scala ... and so many wonderful frameworks we have not taken it to the next level to producing quality CMS. Brix apparently will not be evolved further. which is fine; for its intent it does a good job but what about taking this to the next level. Also, problem with most CMS is they are content centric (ok hence they are called CMS) may seem dumb at a glance. ..but I dont want my business model to go into a JCR repository. Perhaps the intent of the site is to reflect the actual product business model in a neat way with WebDav. Lets call it PMS (hah) for lack of a better abbreviation. Also the ability to customize the admin module to give a Product centric view instead of Content centric view. This allows for greater analytic s and also then using java as an integration platform to integrate the business model with infinite things at the back end with pluggable extensions. I liked BRIX for many reasons. Am wondering if people are thinking about what I mentioned above ..also if we can take Brix further (not core) but by adding extensions and delivering a quality complete solution that could rival something like Drupal in the near future ...or maybe eventually! ..sorry i don't have my own Blog.

Re: Java in CMS arena,..wicket to lead the way?!
@Brian - but there's a lot of fragmented development and not a lot of investment going back in. --- yes, this is what I sense. I'm not even aware of the Brix community unlike Wicket which is more active. If you see the Brix architecture page i put some comments but Looks pretty dead which is pretty de-motivating. I would challenge you to create needs in the core by demonstrating those needs --- No, I dont think the core needs to be changed as such, Simple is better should remain preserved. However we can upgrade the Wicket dependencies from time to time? :) ?! I ALSO like the idea it does NOT have a custom workflow etc built into core, coz I'm a fan of Drools work flow Rules Engines to allocate business logic and workflows; Apache Camel Spring Integration.

Re: Java in CMS arena,..wicket to lead the way?!
@Richard Apache Roller is a Java based blogging system, if you're looking for something. --- I've used Roller and like it a lot functionally. But am circumspect of its integration capabilities with other CMS, and also integration of its Admin module to be a plugin-component into another CMS instead of a stand alone system. Their Wiki isnt that insightful to tell me all this. So beyond functionally what it does stand alone I'd like to understand its integration capabilities more. If you guys know and are doing something in Lenya for that, please share it. I'd love to understand first..and then possibly contribute about things I've mentioned. I think the basic point it to allow *integration*, scripting, plug-in capabilities and not have to provide everything under one roof. I like BRIX for this reason; simple CORE and extend anywhere.. but it suffers from other things I've mentioned above. Will give Leya a shot too. thanks a lot. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Java-in-CMS-arena-wicket-to-lead-the-way-tp2541542p2543399.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket and Spring Security question
I have not gone too deep but @ a superficial level, following observations: 1. I dont see a ClassNotFound Exception. The Exception is NOT saying it Cannot find it in your Classpath! spring-security-web classes are not available dot not mean ClassNotFound. Unfortunately I dont know what it exactly means, but it is not what you are assuming, so I'd look beyond CLASSPATH for starters. 2. It clearly says Configuration problem: ;... Spring Security use Filter Chain Maps. It is suggesting the issue is in the configuration in the chain map. I think you are biasing your issue on ClassNotFound when that is not even the issue. I'd start looking at the XML that defines your Spring Security Context for starters. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-and-Spring-Security-question-tp2549867p2549883.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: instantiate panels in a spring bean
Hey dont mean to arge here but Why not? You can get beans in PROTOTYPE scope (does not have to be re-usable; this aspect of Spring is all about IOC) and leverage IOC to inject panels rather than hard wiring them in the code. I like the idea. fachhoch can you please paste the code, I'd like to work on the problem. I'm a dud in Wicket compared to other geniuses around here but I'd like to have a crack if you dont mind. Note: Ensure your beans are PROTOTYPE not SINGLETON (default); since you really should not retain references to Wicket components ...as Igor mentioned in a recent post! thanks. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/instantiate-panels-in-a-spring-bean-tp2946859p2952155.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: instantiate panels in a spring bean
https://cwiki.apache.org/WICKET/spring.html ..As per my understanding @SpringBean is to inject context services (like DAO's etc ..assumed to be SINGLETON's) and puts them in a ThreadLocal to be available to Wicket Components. Its a convenient way to provide Context to all Wicket components. The purpose seems clear Context sharing of services. I'd further assume these services to be stateless and also Non-Serializable. Since its objects in a ThreadLocal, I guess one can also use it for injecting components in theory. ..I've never tried it that way, if you have please let me know. Injecting components on the other hand is about Injecting serialized objects (which should be replicatable across in a cluster; unlike your DAO's). ..ok, lets not over complicate it by going that far. But from the problem described it seems he wants to Inject Components not Services. ..and I think that is fair. My point is clear, if you want to inject components, then those have to be in PROTOTYPE scope. @SpringBean is just an annotation for convenience but all the documentation examples point to it being convenient to provide Inject Services to wicket components not Injected components. One is Stateless the other Stateful and serializable, I think conceptually that is a big difference. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/instantiate-panels-in-a-spring-bean-tp2946859p2952221.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: instantiate panels in a spring bean
I think there has been a huge ball of confusion here created on my part due to certain concepts i was focused on. The reference to ThreadLocal originated from here: https://cwiki.apache.org/WICKET/spring.html Application Object Approach ... Wicket allows you to provide a custom factory for creating this object, the wicket-contrib-spring project provides such a factory (SpringWebApplicationFactory) that, instead of creating an instance, pulls it out of the spring application context. Wicket keeps the instance of the application object in a threadlocal variable and provides various helper methods in components to get to it, so it is easy to retrieve dependencies in wicket components So the ApplicationObject is bound to the ThreadLocal and I think the Spring Dependencies are bound to the Applicaiton Object, so I made a logical connection there. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/instantiate-panels-in-a-spring-bean-tp2946859p2952889.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

GridView for A-Symmetric tables - issues
Hi,
I'm playing with the following table/grid structure:
+--+-+-+
| | | |
| +-+-+
| | | |
+--+-+-+
|| | | |
+--+-+-+
..where the top-left cell spans 2 rows 2 columns.
The GridView class in the protected void addItems(IteratorItemT items)
method has a do {...} while (); loop. This does not respect the number of
rows specified when calling GridView Object.setRows();
..On overriding this class and making the loop restrict to Number of rows
strict, on Pagination the following issues come:
1. [SOLVED] The DataProvider, the public Iterator? extends Product
iterator(int first, int count) needs to be adjusted to accommodate that
first will correspond to an adjusted value (less my the number of cells
merged.
Example: In a Table where one call is 2x2. Then 1 cell occupies 4 cells.
Therefore Num of merged cells = 3. That means This table can accommodate 2
less items from the Dataprovider.
I'm able to fix this also by adjusting the calculation to calculate the
actual first
2. [NOT SOLVED YET] The Size the DataProvider @Override public int size()
returns cannot change to other than the actual size. But the Paginator stops
short and the remaining Data Items are cut off.
..Am not sure where the issue is conceptually: Grid, paginator,
DataProvider.

Re: GridView for A-Symmetric tables - issues
Hi, I've solved this problem by writing a new implementation of DataViewBase. GridView did not seem appropriate to simply extend due to a few reasons. (It assumes Symmetry for the most in its code). This Code can merge areas within the GRID and extract data from the data model accordingly and can be further customized for Assymetric Grids. I want to sumit this code for review and then into the code base. What is the process? Note: This code was over 1.4.9 so I'll take the latest update to see if there are any changes I need to factor in, but in the mean time lemme know! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/GridView-for-A-Symmetric-tables-issues-tp2953859p2968709.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Dunamic neted List Views
Hi,
I just developed a Menu; that is nested many levels. At the point of
rendering in my code I'm slightly confused. ok, Let the code talk:
(The following code assumes a domain model with MenuItemState which is
hiararchial has children. And each child node is a MenuItemState. The
child can either have null or further children.
The renderMenu() is called by a Panel.)
@Override
public void renderMenu() {
IModelMenuItemState modelState = getState();
MenuItemState state = modelState.getObject();
//Add all menu state objects as Ordered List / sub lists.
add(new ListViewMenuItemState(menuItems,
state.getChildren()) {
@Override
public void populateItem(final ListItemMenuItemState
wrappedChildComponent) {
final MenuItemState childItemState =
wrappedChildComponent.getModelObject();
wrappedChildComponent.add(new Label(name,
childItemState.getMenuItem().getName()));
wrappedChildComponent.add(new
StaticImage(img,
new
Model(childItemState.getMenuItem().getImg())) );
wrappedChildComponent.add(new
StaticImage(rollOverImg,
new
Model(childItemState.getMenuItem().getRollOverImg())) );
wrappedChildComponent.add(new Label(selected,
Boolean.toString(childItemState.isSelected(;
}
});
.. now I can add the children like:
wrappedChildComponent.add(new
ListView(nestedItemsFor_+childItemState.getMenuItem().getName(),
childItemState.getChildren() {...} );
Code: Current markup code::
table
tr wicket:id=menuItems
td/td
td /td
td /td
td /td
/tr
/table
..but how will the above markup code generate the name for the nestedItem
Component know if the item has children. Should I just inject markup
mylsef or using ListView can achieve this cleanly?
I want to introduce nesting from my Model into the markup using ListView!
Ideas?! (I dont wanna keep posting answers to my own questions so quick
replies would help :) ) heh

Re: Dunamic neted List Views
ok as usual I bet myself to it, here is the answer :
Basically use a ListView over a ListView!
@Override
public void renderMenu() {
IModelMenuItemState modelState = getState();
final MenuItemState rootState = modelState.getObject();
//Add all menu state objects as Ordered List / sub lists
//Model MenuItems per Level (layer)
ListListMenuItemState menuLayers = new
ArrayListListMenuItemState();
{
MenuItemState state = rootState;
do {
menuLayers.add(state.getChildren());
state = menuHelper.getFirstFertileChild(state);
} while(state != null); //Keep going (DFS) till Menu
node bares no child
}
//Render:
final ListViewListMenuItemState multiLevelMenuContainer =
new
ListViewListMenuItemState(menuContainer, menuLayers) {
@Override
protected void populateItem(final
ListItemListMenuItemState
menuLayerComponent) {
//Add levels layer by layer (each layer in a
different div on mark-up.
Items in same layer get same styling
//TODO : Work on mark-up styling for final
render details.
menuLayerComponent.add(new
ListViewMenuItemState(menuItems,
menuLayerComponent.getModelObject()) {
@Override
public void populateItem(final
ListItemMenuItemState
childMenuComponent) {
final MenuItemState
childItemState =
childMenuComponent.getModelObject();
childMenuComponent.add(new Label(name,
childItemState.getMenuItem().getName()));
childMenuComponent.add(new StaticImage(img,
new
Model(childItemState.getMenuItem().getImg())) );
childMenuComponent.add(new StaticImage(rollOverImg,
new
Model(childItemState.getMenuItem().getRollOverImg())) );
childMenuComponent.add(new Label(selected,
Boolean.toString(childItemState.isSelected(;
}
});
}
};
add(multiLevelMenuContainer);
}
Markup code looks like this:
table wicket:id=menuContainer border='1'
trtd
ul wicket:id=menuItems
li/li
li /li
li /li
li /li
/ul
/td/tr
/table

*
*
* Issues with {...@link GridView} that make it unfit for extension:br /
*
* The {...@link GridView} class assumes Symmetry of Rows x Cols. In addition
due to certain
* non standardized API methods being final or private the setRows()
setCols() have been overriden
* completely to circumvent the use of {...@link GridView#updateItemsPerPage}
(which uses internalSetRowsPerPage)
* , the name of the method is not appropriate and in the future should be
able to override it with
* asymmetric implementations. (perhaps they had that for standard Loop
scenarios and re-used the same method so the name stuck!)
*
* Also, columns rows is private. If getters setters of columns rows
were simple bean methods those could have been used.
* But since they involve complex logic that requires visibility of the
variables this too becomes unfit for consumption.

Resource caching, Deployment Mode Re-visited

Ajax Panel Update
Hi,
I have a Tree (representing a product line) and an adjacent Panel
representing Product listing within a category/line.
On click of the Link the Panel updates. I have the following code, all works
except am not sure how to go about refreshing the Panel with updated
DataModel:
... In following code: See //TODO: Not sure how to update Panel with
latest Product. So on click I am getting the correct object in Prod
(ProductReference). However I'm failing to translate that into updating the
Panel Model Refreshing the Panel on UI more importantly.
@Override
protected final LinkTree createLinkTree(String id, TreeModel treeModel)
{
return new LinkTree(id, treeModel) {
//node = Name of Link
protected final void onNodeLinkClicked(Object node,
BaseTree tree,
AjaxRequestTarget target) {
Object o =
((DefaultMutableTreeNode)node).getUserObject();
if (o instanceof ProductReference) {
ProductReference prod =
(ProductReference)((DefaultMutableTreeNode)node).getUserObject();
log.info([createLinkTree] + prod);
targetUpdatePanel.setVisible(true);
//TODO: Not sure how to update Panel
with latest Product
}
}
...
(targetUpdatePanel.setVisible(true); is used because initially the Panel is
blank when nothing is selected placeholder markup is used -- FYI)

Re: Ajax Panel Update
Thanks Jc, I employed that.
In addition, the model was inserting a DataTable that was fetching its data
from a DataProvider. So it was necessary to refresh not only the model but
the DataTable; so I separated the initialization of the DataTable as
follows:
/*
* Separating the initialization of the DataTable, as it will be
updated by
Ajax Requests
*/
public void onInitialize() {
super.onInitialize();
Component dataTable = get(productTable);
if (dataTable != null) {
remove(dataTable);
}
add(getProductListing(productTable,
(ProductReference)getDefaultModel().getObject()));
}
..and in the code mentioned pervious for the TODO: now I have:
targetUpdatePanel.setVisible(true);
targetUpdatePanel.modelChanging();
targetUpdatePanel.setDefaultModel(new
Model(prod));
targetUpdatePanel.modelChanged();
targetUpdatePanel.onInitialize();
target.addComponent(targetUpdatePanel);
..and It works. Maybe it can be more efficient clean but its worked out.
Thanks !

onSubmit sequence call with AjaxFormSubmitBehavior
On reading some material, it explains that when a Button is within a Form,
the Buttons onSubmit should be called before the Forms onSubmit. (if not
configured otherwise). Which makes perfect sense.
However; when I add AjaxButton to the Form, and have it within the Form. I
see the order of calling reversed by default implementation.
As I interrogated, it is how the code is written in AjaxFormSubmitBehavior.
Notice: getForm().getRootForm().onFormSubmitted() called before
onSubmit(target); -- See code pasted from that class below. being a pure
Ajax call the form is never actually submitted to it allows it to carry on
to the onSubmit(target);.
The question is, why is there a reverse in the concept?
Is it because target is loosely associated with Any target and we dont
care if it belongs to the form and hence is a third grade citizen? (hence
comes after the main forms onSumit()) ? ; that makes sense imo thinking
aloud.
(since method is not final I dont think this will ever be an issue but I
just want to confirm the thought process)
/**
*
* @see
org.apache.wicket.ajax.AjaxEventBehavior#onEvent(org.apache.wicket.ajax.AjaxRequestTarget)
*/
@Override
protected void onEvent(AjaxRequestTarget target)
{
getForm().getRootForm().onFormSubmitted();
if (!getForm().isSubmitted())
{ // only process the form submission if the form was actually
submitted
- needs to be
// enabled and visible
return;
}
if (!getForm().hasError())
{
onSubmit(target);
}
if (getForm().findParent(Page.class) != null)
{
/*
* there can be cases when a form is replaced with
another component in
the onsubmit()
* handler of this behavior. in that case form no
longer has a page and
so calling
* .hasError on it will cause an exception, thus the
check above.
*/
if (getForm().hasError())
{
onError(target);
}
}
}
Thanks

mount QueryStringUrlCodingStrategy issue when coming via Apache
Hi,
I'm getting a wierd issue.
Have this code: mount(new QueryStringUrlCodingStrategy(admin/login.html,
login.class));
So there is an Admin module for our Web App. All Login Admin pages are
distinctly relative to admin/.
On tomcat this works fine, but when the request comes via Apache I get a
404.
I have also overridden public IResourceStream locate(final Class? clazz,
final String path) {} so that the Package based names are translated to a
folder location for HTML markups outside the classpath.
Any ideas?

FeedbackPanel messages in a Loop (Dynamic Form)
Hi,
I have a form where the number of fields are not fixed so have a Loop where
i add the fields. All these are mandatory. In a loop, your field id is keeps
the same AFAIK. So when there is a validation error the standard message
mentions the component id ..which isnt good enough in a loop, like this:
ListView horizontalSegments = new
ListViewHorizontalSegment(horizontalSegments, hsegs) {
@Override
protected void populateItem(ListItemHorizontalSegment
item) {
String key =
item.getModelObject().getDisplayName();
item.add(new Label(name, key));
item.add(new NameableTextFieldDouble(value,
new
Model(getMeasurementValue(mp.getHorizontalMeasurements(),
item.getModelObject())),
Double.class,
MarshalUtils.toAlphaNumeric(item.getModelObject().name()))
.setRequired(true));
}
};
add(horizontalSegments);
When I submit the form and say 5 of them are blank. I get 5 messages saying
Field 'value' is required.
Thats understandable because the FeebackMessage in the FeedbackPanel feeds
of the component ID.
While debugging I see FeedbackMessage apparently maintains some reference to
the 'Reporter'.
When I look at the code I see a ton of final methods etc, and having some
trouble modifying the method that creates the message. My reporter component
(NameableTextField) knows the correct name.
Can someone provide simple way of overriding that message
thank you.

Re: FeedbackPanel messages in a Loop (Dynamic Form)
There seems to be another problem. On error the form values are not retained. The same form also has some normal fields (outside the loop). The notmal form fields that are NOT in a loop retain their values (on re-load) I even removed my own NameableTextField and am using standard simple TextField in the above code but its not retaining the values (when there are errors). Am debugging it but in the mean time if someone has an idea or even a did you try this? please let me know. P.S: This problem does not seem related to .setLabel(name). Its something else and has something to do with the components being the loop. thanks -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/FeedbackPanel-messages-in-a-Loop-Dynamic-Form-tp3204893p3205706.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: What already redirecting error?
Hi,
I have a very very Dynamic Form. In the public void onSubmit() {...}, due
to some Change in a Drop Down the entire Form changes.
To keep it simple I just decided to Re-Load the entire page.
but looks like from onSumbit() you cannot call
getRequestCycle().redirectTo(...) or you get the exception:
Already redirecting to '?wicket:interface=:12'. Cannot redirect more
than once.
Frankly, I'd like to replace the Form Components in the OnSubmit() given a
Choice instead of a redirect. But addOrReplace components in the Form doesnt
have any effect. Apparently, only Changing the Model of Components already
added works!
Q1) So for starts whats the best way to re load the page in this case
Q2) Even Better, can I Replace Form elements in onSubmit()? ..or somewhere
close? (This is better as I can use the FeedbackPanel to convey messages
after the form has changed)
thanks

Re: multiple feedback panels in same page
Hey i think this is documented, thats who I got to know.
Basically a 2 step process. You create a Behavior like:
/**
* This class defines a behavior so that in Feedback (on validation errors)
individual
* fields can be marked by the markup provided by the {@link
this#getErrorMarkup()}
* @author Arjun Dhar
*
* @param T
*/
public class MarkErrorFieldBehaviorT extends AbstractBehavior {
private static final long serialVersionUID = 1L;
@SuppressWarnings(unchecked)
@Override
public void onRendered(Component component) {
FormComponentT fc = (FormComponentT) component;
if (!fc.isValid()) {
Response response = component.getResponse();
response.write(getErrorMarkup());
}
}
/**
* Provide HTML markup to mark the error fieldbr/
* Example: lt;span style='color: red'gt;*lt;/spangt;
*
* @return
*/
protected String getErrorMarkup() {
return nbsp;X;
}
}
..and for your field all you have to do is .add(new
MarkErrorFieldBehaviorDouble()) -- add the behavior to it.
In my case I'm happy with X appearing. Adapt it to put the field name or
whatever text you want!

Changing/Accessing name of ListItem in ListView
Hi, when using a ListView, the name uses the following format to Render. loop name:index:field id In onSubmit(..); this is fine if you know the order of the list. However say if the primary data Structure is a hashmap then its more convenient/elegant to retrieve by Name. I can change the name of the attribute but Wicket does not recognize it when one does get(componentId). Using ListView.getList() I can access the Model, but this does not help getting the access to the individual components. Looks like the only way is to use a numberic counter and construct the Component ID's to access it one my one. Is there a way to change the component Id ..or perhaps access these by name? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Changing-Accessing-name-of-ListItem-in-ListView-tp3218777p3218777.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Changing/Accessing name of ListItem in ListView
I was hoping on the lines, where you do get(component id); Wicket returns
the Component.
So if there was a way to customize the nomenclature of what the names of
the fields are in a loop then it would be easy to refer to components via
name directly.
... I can't do [IN CONCEPT] get(additionalFeatures).get(My naming
convention Sub Item component Id).getDefaultModelObject() or something.
-- I was asking if there was any magical way like that.
Not a big deal , I worked around . For the sake of discussion my ListItem is
defined by the following:
ListView additionalFeatures = new ListViewString(additionalFeatures,
additionalFeaturesKeyList) {
...
@Override
protected void populateItem(ListItemString item) {
String key = item.getModelObject(); //Assume
this to be the Name / Id of
something
item.add(new Label(name, new Model(key)));
String modelKeyName =
MarshalUtils.toAlphaNumeric(key);
final Feature feature =
additionalFeaturesMap.get(key);
item.add(new TextArea(value, new
Model(feature.getValue().toString()))
.setLabel(new
Model(modelKeyName))
.setMarkupId(key));
}
...
}
What I went with at the end was:
ListView listView =
(ListView)get(additionalFeatures);
for (int x=0;
xlistView.size(); x++) {
ListItem
additionalFeatureField = (ListItem)listView.get(x);
//Now I work
with the ListItem however I want to and derive what I want :)
...
}
..Which works also, but not as elegant as I hoped. But I realize its a LIST,
so my expectations are perhaps unjustified and iteration of the list is
logical and inescapable.

Re: Best practice on i18n
The only relevant technical point here is Inheritance.

Dynamic Tag substitution
Hi,
Im creating a Decorator/Wrapper Panel that will show EDIT/DELETE options on
the content if the user is authorized to do so.
The markup simply put, is like this:
?xml version=1.0 encoding=utf-8?
html
body
wicket:panel
table
trtd DELETE /tdtd EDIT /td/tr
trtd colspan=2div
wicket:id='container'***TAG_TYPE***wicket:id='component'
//div/td/tr
/table
/wicket:panel
/body
/html
The issue is that the Wrapper by design can consume any Component and
decorate it. However, the TAG type depends on the component inserted. I'd
liek to control that programatically. Is there any way I can do that?
..the corresponding code is like :
public abstract class EditableComponentWrapper extends Panel {
private static final long serialVersionUID = 1191322949129480444L;
private boolean allowDelete, allowEdit;
public EditableComponentWrapper(String id) {
super( id );
WebMarkupContainer container = new WebMarkupContainer(container);
add(container);
container.add(addComponent(component));
}
/**
* Add custom Component to the container. Use the id passed to construct

Re: Dynamic Tag substitution
One correction I'd make to my own code is instead of allowing to add a Component; I'd enforce WebComponent. That would make the case stronger for using and enforcing HTML tags. ..the issue remains, hwow do I make the markup here dynamic to suit the WebComponent being wrapped! :( - Don't take life too seriously, your'e not getting out it alive anyway! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Dynamic-Tag-substitution-tp3311189p3311199.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
DropDown replacing text field
Hi,
i have a markup (Loop) for a couple of fields. Its a dynamic form and all
the fields are text except one or two,
Sample Markup:
Now in the Java code, for the exceptional case I want to replace that
'input' with 'select', so I did:
field = new DropDownChoice(value, new Model(myBooleanvar),
Arrays.asList(Boolean.FALSE,
Boolean.TRUE)) {
//Default is text type, change
to select
@Override
public void
onComponentTag(ComponentTag tag) {
tag.setName(select);
tag.remove(type);
super.onComponentTag( tag );
}
};
..this results in a Blank Drop Down Box withotu any values.
In the markup if I make it select it obviously works.
What else do I need to to do to get the options, in the list in such a
case?

Externalizing Page Mounts Via Spring
Hi,
I wanted to externalize the Page Mounts using Spring.
Earlier in my Application class the code was like:
mount(new QueryStringUrlCodingStrategy(login, loginPage.class));
So What I did was:
...
//Scan for All IMountLoaders in the context and get the
Mount points from them automatically
Map mountLoadersMap =
springContext.getBeansOfType(IMountLoader.class);
List mountPoints = ... Get Mount Points from Spring ...
for (IRequestTargetUrlCodingStrategy mountPoint : mountPoints) {
mount(mountPoint);
}
...
: SPRING FILE CORRESPONDING CONFIG :
However this leads to an Exception:
.springframework.beans.BeanInstantiationException: Could not instantiate
bean class [com.me.loginPage]: Constructor threw exception; nested exception
is java.lang.IllegalStateException: you can only locate or create sessions
in the context of a request cycle:

at
org.apache.wicket.Application$1.onInstantiation(Application.java:299)
at
org.apache.wicket.Application.notifyComponentInstantiationListeners(Application.java:1093)
I wanna keep the code fluid and dont wanna wire it to any specific
@SpringBean kinda config. Is there an easy way out here?

Caching Streamed Images on browser
Hi, I have a resource (an Image which exists on the File System outside the Web Context). I stream the image resource. The problem really is that while the speed to download an image within web-context and outside is the same the one within Web-Context is always cached by the browser. Am not sure this is a pure wicket question, but anyone know the rules for browser caching images? As long as the src link is the same and independent of session why would the browser not cache it? I also created a simple DownloadServlet and same result.

Re: Caching Streamed Images on browser
Hey, thanks for the response ... though i think there is more to it. When I look at the header of a normal image in web context, he server returns 302 (NO MODIFIED). Despite me changing the HTTP cache controls, a HTTP/1.1 200 OK still makes the browser stream the image from the server. Using HTTP live Headers i ensured the HTTP headers match that of normal image Ditto. This (200 vs 302) is the only noticeable difference. Am unable to force a 302 for some reason (...am looking at that) Any ideas? Will some sort of UrlCodingStrategy to avoid params in my URL trick the browser and tomcat server in thinking its a genuine image resource? like : /my/synthetic/image/image1.jpg instead of Download?image=image1.jpg.

Re: Caching Streamed Images on browser
Got it! As per ETag specs in Firefox Docs,: The Last-Modified response header can be used as a weak validator. It is considered weak because it only has 1-second resolution. If the Last-Modified header is present in a response, then the client can issue an If-Modified-Since request header to validate the cached document. When a validation request is made, the server can either ignore the validation request and response with a normal 200 OK, or it can return 304 Not Modified to instruct the browser to use its cached copy. The 304 response can also include headers that update the expiration time of the cached document. Setting 'Last-Modified' did the trick for me. thanks - Don't take life too seriously, your'e not getting out it alive anyway! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Caching-Streamed-Images-on-browser-tp3389269p3436099.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Complex Grid with Wicket

Now, many months later here is what I feel: IF YOUR JAVASCRIPT SKILLS ARE GOOD :: If you can get away with producing JSON or any form of object notation and deliver that the the page, and have the Page decide via JQuery, Javascript + DHTML or some other pure client based solution then ...Do that! It gives you more maintainable and flexible code* and clear Server/Client abstraction. I've realized Table rendering is one of those things that are best left to client pages (if you are ok with a JavaScript solution). ...if not, you can scrape from my earlier work on that post. Its your choice , your neck! :) * For most reasons, ~~~ Browser specific JavaScript is a Pain and best avoided ~~~, but I've found table handling etc. one can write pretty much standard and consistent JavaScript that beats writing code server side. Again, it about your JavaScript skills Vs Wicket skills perhaps and a personal choice.

I'll put a script via WebPage.setHeader(...) in my base class; extended by all pages that use a session.

Pre Publish Wicket Pages
Hi, Is there some way for me to Hack the Wicket parser to pre-publish Wicket based pages before they are even rendered? Context: == I have a system where I'm using velocity to generate pages that do not change over a period of time. Futhermore their content can be cached using EhCache (More interesting as based on events one may update thee cache also, so for semi dynamic content also its great). This is really performant and great for other reasons. ..However since i love wicket and templating using inheritance in Wicket etc., I want to pre-publish my core wicket pages also (which render dynamically on screen on request). I'm perhaps confusing/mixing the purpose of a Templating engine with Wicket. But who cares :) , ... I think it would be cool to pre-publish certain Wicket pages also. How would that be possible? There would be no Request, no Session. So some hacking of the parser would be required. - Software documentation is like sex: when it is good, it is very, very good; and when it is bad, it is still better than nothing! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Pre-Publish-Wicket-Pages-tp3682723p3682723.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

RE: using saml2 for authentication
I dont think its justified to expect Wicket to directly provide that Auth support. My 2 cents to put you in the right directions AFAIK: Typically, one should have an IDP or SP setup at either ends. For instance, Shibboleth has good support for SAML2. Once you have that setup, you can use any java based app to interact with your SSO. Note: I've tried both CAS and Shibboleth. CAS current version for SAML2 is not reliable. So you should get familiar with Shibbolth I guess.

Technical Limit on Mount Points
Hi,
I fave a ton of possible dynamic content where for each content I have to
associate a Mount Point.
im thinking of a strategy to do that efficiently.
To cater to it, following questions:
1). What decides the technical limit to the number of Mount points possible?
(Does it load all the mount points into memory, or applies some sort of
caching that can use persistence if required)?
Example usage per mount point: application.mount(new
MixedParamUrlCodingStrategy(myPageX, pageTemplateClass, new
String[]{pageId}));
2). Would a considerable number of Mount points degrade performance?
thanks

Re: RFC: Ten things every Wicket programmer must know?
From my experience, stuff where I screwed up or wasted time: 1. Wicket is a UI framework, delegate as much as possible to your own neutral code base service and components. Data Models etc. Both Server and Client Side. Client Side:: Don't wrestle with Grids etc in Wicket; if you can get away with a cheap JavaScript/DHTML implementation instead. 2. Wicket Data Models should ideally wrap you native business objects. Wicket wotks over the native business objects; your business objects POJOs are not designed for wicket. 3. Use Detachable models effectively. (Am still learning the meaning of *effectively*). Example: Everyone talks about using it, but it depends on the underlying business objects in use. If they are poorly designed and load in an in-effiient manner, then load() will mess with re-loading stuff each time. 4. Do not try to instantiate Wicket Components via Spring. there is no sane reason to do this; this was an area of special interest and very tempting. One can rely on Spring for native objects and develop better mechanisms for Components to instantiate over the Spring defined layer. 5. @SpringBean is bloody useful 6. Learn to hack Mount Paths. The default Markup Page classpath relating to the component is Web non-intuitive. Its great if you can live with the default setup but learn to mess around with mounting. 7. Learn to the differences between Markup Inheritance, Use of Panels and Include when it comes to designing reusable templates and reducing boilerplate markup code. 8. Mess around with Fragments; they are useful. Like Anonamous classes ; but just in the markup world. 9. Learn atleast one other Web Framework like Struts, appreciate the beauty of Wicket. 10. Learn to respect velocity templates and the co-existence of Wicket with Velocity.

Advanced Mounting Markup Location
When Locating the Markup for a Page, I want to know the corresponding class
(associated with the page/markup).
Currently Im directing Wicket to my Custom Markup location with the
following code in Application:
...
final IResourceStreamLocator defaultLocator =
super.getResourceSettings().getResourceStreamLocator();
return new ResourceStreamLocator(){
@Override
public IResourceStream locate(final Class? clazz, final String
path) {
...
//Figure alternate path by reading path
//if valid URL not found use the defaultLocator
...
}
...
I want to get the associated Component class. I know the String path
represents the ClassPath, but its still a String and contains Locale Junk
an extension with it.
Is there someway I can get Class? directly so I don't have to do String
manipulations?
Another thing I want is, when the dynamicPage (which --extends--
TemplatePage --extends-- WebPage) appears it knows its associated
Template DataStructure details.
TemplatePage - Wicket Component
Template - Data Structure
TemplatePage --- Template
When Mounting, on init() in Application:
application.mount(new QueryStringUrlCodingStrategy(pagePath, [Templace
Class] ));
During the mount itself, is there anyway for me to associate/pass models to
the pages which will be constructed?
Wicket uses no-arg Contstructors for WebPage, but what if I want to pass a
WebPage contexutal info specific to the Page while mounting? (Can i do
this?) -- I believe this would be efficient

Request to the Developers ::
One particularly disturbing thing I've seen in certain wicket components
(maybe an oversight); is that if you dont have POJO style getter()
setter() on your components; then non final variables should be declared
protected not private. There is no point providing overriding methods that
use private variables, to which the child class has no access.
