Lessons from Wicket Cookbook

[Clint Checketts]

While clearing out my drafts folder I found this.  While reading through
the Wicket cookbook by Igor (
http://www.packtpub.com/apache-wicket-cookbook/book) I noticed that I was
learning a ton of new interesting stuff about the Wicket way of doing
things, so I kept notes.

This draft is from over a year ago (Mar 2011), but the information is still
accurate for the book.* I highly recommend this book.*

-Clint


   - Form override onValidate input.getConvetedInput() gets value before
   its been stored in the input's model pg 11
   - Single validator displaying multiple messages: pg 16
   - Better way to set custom variables for error messages: pg 17
   (error.setVariable("max", max);)
   - FormComponents automatically know how to convert to the model object
   because the implement IObjectClassAwareModel, otherwise
   formField.setType(Class) is required pg 31
   - DropDownChoice wantOnSelectionChange (pg 38) makes a select box
   autosubmitting
   -  (pg 42)  is the same as adding a component to a
   div and calling setRenderBodyOnly(true)
   - getConvertedInput can return a new instance of an object, and in
   updateModel you would copy the values over into the existing object, if you
   wanted to update the existing object (pg 45), be sure not to call
   super.updateModel() though
   - We can use Wicket's metadata facility to store data in the Wicket
   session without forcing a specific sub-class of session (pg 52)
   - aTextField.clearInput() forces a value="" on a text field ensuring
   that it is blanked out even if the user had typed something before (pg 57)
   Validation failure would otherwise retain the value and keep displaying it.
   - The AttributeAppender behavior doesn't allow for the replace model to
   be set after the constructor, and getReplaceModel is final so the
   implementation as listed on pg 62 is the best way to update a
   FormComponent's class when checking isValid()
   - Page 64 - remember to add form.visitChildren calls after all children
   have been added to the form.  Making the call in onInitialize isn't wise
   since that call actually happens as part of the 'add()' call in it's parent!
   - Question: Would separate components in separate app sessions cause
   feedback messages in each other's pages? pg 71
   - IAjaxRegionMarkupIdProvider can be used with a behavior to clean up
   extra surrounding markup around components pg 74
   - Example using MicroMap (map that holds a single value and is populated
   in its constructor, and MiniMap) and the Model.ofMap() factory usage,
   finally using getString("keyInPropFile",mapmodel) for manually getting a
   property message and displaying it. pg82

Re: AjaxPayload equivalent in Wicket 1.4

[Clint Checketts]

Right Martin, so your code allows me to select the children to refresh via
Ajax.

My question was how can trigger the logic processing in the ParentClass
automatically. As you noted in the code, the child panels will have to
remember to call the parent.update(t) line. I'm fine with that solution,
but I was wondering if there was another way.

For example would that page's onBeforeRender get called automatically if a
link's onClick is called?

The more I think about it it feels like I'll use:
parent.update(ajaxReqTarg, PayloadType.MONITOR). Then each child panel will
implement an interface like: 'getPayloadSubscriptions()' and if any report
that they care about 'MONITOR'ing payload they would get added to the
AjaxRequestTarget since each render needs to report what type of payload
update we are looking for..

AjaxPayload equivalent in Wicket 1.4

[Clint Checketts]

I want to create a parent panel that will have several child panels. I'm
making it so the parent panel will automatically add child components to
the AjaxRequestTarget via its logic and detecting which ones it detects
need to update. I can see how to make it work great if the AjaxLink calls
the parent panel in it's onClick, but is there any method or hook I can put
in the parent panel itself that would be able to detect that a request is
happening and decide to add the child components automatically?

I know 1.5 has this, I'm just trying to make it work in 1.4.x for now since
the planned upgrade to 1.5 is a ways away for this project.

Is there a solution without overriding anything in the application class?
If it isn't possible, what is the minimum application class changes
required? (WebRequestCycleProcessor?)

Thanks,

-Clint Checketts

Re: Can't Reset Form After DropDownChoice OnChange Handled

[Clint Checketts]

Yes, you can reset the form quite easily, with or without Ajax. I haven't
read the rest of the thread, but if you just reset the object that the form
is referencing all the fields would stay in sync and be 'reset'.

Re: How to build a hudson/jenkins like live log viewer?

[Clint Checketts]

I'd need to look at Tailer to see how it operates. But here is how I'd try
it (it is quick and I don't like the markup, but we'll optimize it later:

Create a panel that looks like so (we'll call it LoggingPanel):


log contents
next log call


Add a self updating timer behavior so the panel check the Tailer for
output, if there is data, then update the logData label with it, make the
nextLog component be another LoggingPanel with a SelfUpdatingTImerBehavior,
and stop the timerbehavior on the current panel.

Drawbacks are: the divs keep getting nested, so the markup isn't the most
beautiful, so setRenderBodyOnly(true) might make it nicer.

Re: What is the difference between Model , PropertyModel,CompoundPropertyModel?

[Clint Checketts]

Model is like a box. It is just a container. Put your object in and get it
back out.
PropertyModel lets you put an object in the box and always lookup a value
on that object, and set that value
CompoundPropertyModel merely removes the string setting which value is
pointing to the object and uses the Wicket:id of the corresponding
component to reference the property

The examples Steve linked in the wiki are great.

Re: Orders of CSS files

[Clint Checketts]

You can manually add in the autocomplete's CSS file yourself, and wicket
won't re-add it in. That way you can add in your custom CSS after it.

Re: Community tools

[Clint Checketts]

So what is the best way (official? permanent?) to link to a previous
response?

In 6 months when someone has a similar question, what is the official way to
link to previous answers? Equally, what is the best way to improve those
answers if the answer 6 months back worked at that time, but now is invalid
and a 'bad practice' due to wicket improvements?

Folks so rarely use the mailing list archives (
http://wicket.apache.org/help/email.html), (not easily searched!) I doubt
that is the solution.

Re: Ultra strange behaviour AjaxButton - Form

[Clint Checketts]

Are you using a custom object? A converter could be failing to do the
conversion. As in you have a 'User' object tied to your field and Wicket
doesn't know by default how to convert the text 'Bob' into a new User
object.

Re: CheckGroup updateModel + setrequired (Bug?)

Even if you can't upgrade the production version its worth testing it
against the newer version of Wicket to see if the bug is resolved.

Re: dynamic DataTable

[Clint Checketts]

Sorry for taking 2 weeks. Here is a quick and dirty implementation:
https://github.com/checketts/wicket-datasource-table

It needs a bit of cleanup. 2 points that I like to note is 1) the use of a
datasource instead of a java.sql.Connection will allow automatically opening
and closing connections (so the table provider will manage itself and 2) the
use of the ResultSetMetaData to grab the column names and count.

I'll try to get around to cleaning it up (patches are welcome!) but since I
hadn't improved it in the last 5 days I figured I should just get it out
there in it rough cut glory. Its using H2 right now for the JDBC backend,
but you'd be able to switch out any equivalent driver.

Re: RFC: Ten things every Wicket programmer must know?

[Clint Checketts]

My Top 10 (some already mentioned):


   1. Use LoadableDetachableModels
   2. DefaultModels get detached otherwise you need to detach your model
   manually (as Dan mentioned)
   3. Setup components to pull in their data and state, typically via
   models. This includes pulling in a components isVisible/enables/list entries
   4. Feel comfortable with anonymous inner classes, the inline code helps
   readability, just don't get so comfortable you never refactor it into its
   own separate class once it gets large (if it doesn't fit on your screen
   anymore)
   5. Make sure your component hierarchy matches your markup hierarchy: did
   you add the component in your java code? Did you add it to the correct
   parent (form, repeater, page)?
   6. Understand the Form processing lifecycle: Check required, converter,
   validation, update models, onSubmit/onError.
   7. Using Ajax? Understand the difference between AjaxEventBehavior and
   AjaxFormComponentUpdatingBehavior (the second triggers form processing on
   the field)
   8. Clean up your page layout using markup inheritance
   9. The covariant get() methods for WebApplication and Session are super
   useful, create your own version in your own Application and Session to clean
   up your class casts.
   10. Speaking of cleaning up casts... using Generics on your components
   (and models) are worth it. And feel free to use  if there is no
   underlying model or object (I typically do that with Links, Buttons and
   simple Forms that I'm not setting a specific model on).

These things are all fresh in my mind since I'm teaching Wicket this week.
;)  Good luck on the article Jeremy!

Re: DropDownChoice updates onchange event.

[Clint Checketts]

Show the code for savedReportsDropDownList. I suspect you aren't using a
Model.

Also a couple of tweaks to your code. Your calls to 'setChoices' indicate a
'pushing data' approach. Like you are setting the lists in those components
instead of using models there to. I think that is where you are hitting your
snag.

Include the html for your 'displaySortingPanel' please.

Re: Avoid doing lot of Ajax request

[Clint Checketts]

I'm not sure I understood your response. Are you saying you don't want to
set the throttle for every link you do? If so, sub-class it and reuse your
special subclass that always throttles.

You can throttle events.

See setThrottleDelay() on your behavior.

Re: AjaxEventBehavior("onchange) and AjaxFormComponentUpdatingBehavior("onchange") on same DropDownChoice

[Clint Checketts]

Why not put everything in the AjaxFormComponentUpdatingBehavior?

As in:

   dropDownChoice.add(new AjaxFormComponentUpdatingBehavior("onchange")
{

   @Override
   protected void onUpdate(AjaxRequestTarget target) {
   LOG.debug("New updated value: " +
this.getComponent().getDefaultModelObjectAsString());
   target.addComponent(this.getComponent());
*
//This code was in the AjaxEventBehavior before
 LOG.debug("DroDownChoice's parent " +
IntegrityLevelDropDownPanel.*
*this.getParent().getParent().**getParent());

target.addComponent(* *IntegrityLevelDropDownPanel.**
this.getParent().getParent().**getParent());*

   }

   });

Re: Forward to Bookmarkable

[Clint Checketts]

What do you mean by 'hide the url'? Do you mean obfuscate the URL?

BybridUrlEncodingStrategy will let you display a bookmarkable URL that is
stateful (so it isn't the actual bookmarkable page)

For example: /mayapp/welcome.0

Note the .0 on the end. If the user's session expires, I believe it will
attempt to reload the page, but it will create a new one if the expected
version isn't in session.

Re: AjaxLink onclick being called twice

So you click the link and the modal displays, you dismiss the modal, click
the link again and nothing happens?

Is the behavior consistent across browsers?

Mount your page to give it a custom URL.

Re: WicketStuff artifacts naming strategy

[Clint Checketts]

I seem to recall the Maven guys recommending against periods in artifactIds.
Can't find the link for the info though... maybe it was just soething they
mentioned in the class.

The purpose was to reduce confusion between artifactIds and groupIds.

Re: WicketStuff artifacts naming strategy

[Clint Checketts]

Why not just just use wicket- as the prefix? The groupId shows that it is
org.wicketstuff.

Re: Wickettester testing a given WizardStep

A wizard is a component, so you should be able to use startComponent for it.

Re: AutoCompleteTextField which uses an Object, not a String

[Clint Checketts]

Yesterday while playing with AutoCompleTextField, I created a quickstart to
show how it is 'broken'. I hadn't thought of using a converter. After using
a converter the component behaves as I'd expect.

So a simpler solution could be: 1) improve the AutoCompleteTextField's java
doc to explain using the converter 2) update the wicketExample page to
include an example using a converter, 3) add some logic, or an ease of use
hook so that AutoComplete can detect when its being used against objects
that aren't strings and is breaking.

I'll open a Jira, attach the quickstart and attach a patch that takes care
of those 3 pieces. Yesterday I glanced at the ObjectAutoComplete and it
looks very powerful, but maybe even more complex.

My initial desire was that an AutoCompleteTextField mirror how a
DropDownChoice behaves by default. I'll try to demonstrate that in my patch.

Re: AutoCompleteTextField which uses an Object, not a String

[Clint Checketts]

Is there a good reason (besides backwards compatiblity) that the
objectautocomplete hasn't replaced the broken string based one in
wicket-extensions?

It seems like AutoComplete should behave as similarly to DropDownChoice as
possible. As it currently is, IChoiceRenderer feels broken with it.

Re: CompoundPropertyModel for label?

[Clint Checketts]

You need to set the CompoundPropertyModel on the parent object. In your
example the page. Try the following code:

   customer = new Customer();
   customer.setFirstName("Jimmy");
   customer.setLastName("Dean");
   customer.getAddress().setStreet("123 Easy Street");

   myModel = new CompoundPropertyModel(customer);
   setDefaultModel(myModel); //This sets the page's model, which is
the parent to the label's in question

   add(new Label("firstName"));
   add(new Label("lastName"));
   add(new Label("street.address"))

Re: FormComponent convertInput for children FormComponets

[Clint Checketts]

I created https://issues.apache.org/jira/browse/WICKET-3765 and attached a
quickstart.

I commented out the Form in the quickstart. Just uncomment those lines to
see the bug.

Regarding the strangeness of the Form in the FormComponent: I may be able to
remove the Form. This is an older component that I created over a year ago
and finally figured out how to do it correctly when reading the Wicket
Cookbook, which exposed this behavior.

I may be able to refactor the inner Form out of the FormComponent, but the
nature of my component is that the repeating element (as in a TextField) is
configurable so it could be a TextField, or  some other custom field (which
could in turn have a possible inner form) so I want to make it as resilient
as possible.

Thanks!

Re: FormComponent convertInput for children FormComponets

[Clint Checketts]

I finally had a chance to create a quickstart and play with it. The issue
happens when my FormComponentPanel has its own form. So it appears that the
inner form delays the processing of those inner elements.

Once I removed the inner form so the child FormComponents were added
directly to my FormComponentPanel the getConvertedInput worked as expected.


   <This inner form in
the panel was the culprit!








So this leads into another question: Is the a better solution to making it
work if I can't remove the inner form?

Re: the html pages showing traces that we used wicket, is it a problem

[Clint Checketts]

You can override the RequestCycleProcessor to swap that out. Not the
simplest change, but the hook is there.

I'd say that you don't really have anything to worry about though.

Re: Customize Validator Message based on Dynamic Variable

[Clint Checketts]

You could override the variablesMap() method to add in your values that the
message in the properties file contains:

Similar to the message: '${input}' isn't a valid widget.

Re: FormComponent convertInput for children FormComponets

[Clint Checketts]

I'll validate my code again. It is running on Wicket 1.4.1 so maybe it was
linked to the older version.

Thanks everyone for the help, its good to know that it is working correctly
for others.

Re: FormComponent convertInput for children FormComponets

[Clint Checketts]

Sven,

Having that code in updateModel is too late. The input needs to be converted
and set to make it available to validators. The form processing cycle is
roughly:

1- User submitts the form
2- Required fields are checked for existence
3- Input is converted
4- Validators run
5- Models get updated
6- onSubmit logic fires

I need the logic in the conversion step so it is available in the validation
step.

If the ChoiceRenderer ID isn't unique or it has trouble matching it with the

FormComponent convertInput for children FormComponets

[Clint Checketts]

  I have a FormComponentPanel that contains multiple child formcomponent.
The purpose of this panel is to be able to add in several cihldren
dynamically. The end model is supposed to be the list from all the children
component. I get the value in my convertInput() method by iterating over all
the children components, calling each one's getConvertedInput()

Here's the problem, the child component's values haven't convertedTheir
input at that point, so i call 'validate()' on each one to trigger that
coversion.  Is that the right way to approach this? Am i causing
unneeded/duplicate processing?
.

protected void convertInput() {
  final ArrayList convertedInputList = new ArrayList();
  inForm.visitFormComponents(new IVisitor() {
   public Object formComponent(IFormVisitorParticipant formComponent) {
if (formComponent instanceof FormComponent) {
 FormComponent fc = (FormComponent) formComponent;
 *fc.validate();
* T convertedInput =  *fc.getConvertedInput();
* if(null != convertedInput){
  convertedInputList.add(convertedInput);
 }
}
return Component.IVisitor.CONTINUE_TRAVERSAL;
   }
  });
  setConvertedInput(convertedInputList);
 }

 Thanks,

-Clint

Re: MarkupNotFoundException strange behavior

[Clint Checketts]

This happens because you don't have an HTML file for your page. (Assuming
you are extending WebPage). You'll need to tell more about your setup and
when you are extending to really pinpoint the issue.

EmployeeDedicationLoad extends WebPage, right?

Re: How to bind object in Hashset to CompoundPropertyModel expression

[Clint Checketts]

You could try a helper method that allows indexed access.  As in:
userAccount.
*membershipsAsList*.0.acceptedTerms

I haven't tried it and guaranteeing the ordering would need to be accounted
for. But its a potential direction.

Re: TextField not getting the value after a validation eror

[Clint Checketts]

I'm not sure I understand the steps that cause the problem.


Case 1
1- A user opens the page
2- The user click the link, updating the value textfield
3- User submits the form, no validation error occurs, all is well.

Case 2-
1- user  opens page
2- user submits form
3- required error apears, field is still empty

Case 3-
1- user opens page
2- user clicks link, populating the textfield
3- user deletes the text from the text field
4- form is submitted, causing validation error and the textfield is
repopulated with the value the clicked link put in it

Is case 3 the problem you are hitting?

Re: Separate log files (tomcat, hibernate, wicket, etc)

A hint to direct you: setup different 'categories' based on package you want
to split it out on, then setup a separate appender for each of those
categories to go to your separate files.

I don't have an example for you though.

Re: DataTable's view does not always update

[Clint Checketts]

The reason for the 404 is the Websphere is checking for a file, then
intending to filter before and after serving up the file. Since it finds no
file to serve, it returns the 404.

You could direct the non-wicket form's action to direct to a page and use the 
PageParameter's object to parse the input.

I did that for a while until I finally learned how to use Wicket forms the 
right way. It worked quite well.

You can parse in the values, manually checking validity (even manually running 
validators if you like) and still log your own feedback messages.

Re: How to fail validation if ListMultipleChoice is empty

[Clint Checketts]

Good catch on AjaxSubmitButton being deprecated, I guess an IDe would have
made that obvious ;)

I do have to say using the getChoices over a proper model may give you more
work than needed in updating the underlying model objects (maybe consider
overriding the getConvertedInput to return getChoices)

It sounds like you have different buttons for adding and submitting. Correct
me if this is too hackish, but you could change the validator to check if
the addBtn is the submitting button, and ignore the validation in that case:

  form.add(new AbstractFormValidator()
  {
public FormComponent[] getDependentFormComponents()
{
  return null;
}

public void validate(Form form)
{
  List sets = targettedSetsList.getChoices();

  if ((*!addBtn.equals(form.findSubmittingButton()) &&* sets.size() == 0
) {
targettedSetsList.error((IValidationError)new
  ValidationError().addMessageKey("error.noSetSpecified"));
  }
}
  });

Re: DataTable's view does not always update

[Clint Checketts]

Make sure that sendredirect.compatibility property is set to false or
deleted. It causes problems. You didn't say if it had originally be set or
not though, lets make sure it didn't get left on at some point.

Watch the URL, if you typed in http://localhost/myApp and it renders as
http://localhost/myApp/*myApp* (note the duplicate context root) you could
get 404s.

Also convert to using the WicketServlet, WAS had trouble pointing to a
filter as an endpoint (unless you have an empty index.htm file). Lets see if
that gets you back on track. I suspect that is why your clean app isn't
working, you have no index.htm file to trick WAS into working.

Re: How to fail validation if ListMultipleChoice is empty

[Clint Checketts]

You are correct that the Form's validation should only fire when submitting
the form. When an individual element is updated via ajax (as in an
AjaxFormComponentUpdatingBehavior) then just the processing and validations
steps are fired for the individual form component.

It makes me wonder if you are using an AjaxSubmitButton instead of just an
AjaxButton. (Or similarly an AjaxSubmitLink instead of an  AjaxLink) Mind
including your button's code?

Also, why are you calling getChoices() instead of getConvertedInput() in the
validator? Choices represent the possible selection options, the converted
input is the value of the selected choices.

Re: How to fail validation if ListMultipleChoice is empty

[Clint Checketts]

Lets see the code about 'adding elements by pressing on a button'.  The
'getValue()' method is returning the value from the list box's HTTP
submitted values, if the add button is submitting values via ajax or some
other means then it may need a different approach.

Re: Customized AjaxPagingNavigator to highlight selected page number

[Clint Checketts]

If you navigator has a unique class (or id) you could just refer to it via the 
CSS:

I'm guessing something like .goto em{font-weight: bold; font-color: blue} would 
work. Note that disabled links by default are wrapped in  tags.

If that isn't good enough, you can subclass the AjaxPagingNavigator and 
override the newPagingNavigationLink() method. In there you could add a 
behavior to do your custom styling or set the setBeforeDisabledLink() and 
setAfterDisabledLink() methods to insert in the markup you require.

Re: DataTable's view does not always update

[Clint Checketts]

I've seen that sort of behavior in 2 common types of cases:

1- An exception occurred, disrupting the Ajax response from even returning 
(you'll notice it as a type ERROR in the Wicket debug panel)

2- A form validator, required field, or conversion failed, stopping the form 
from updating underlying models (you would have still seen the onBeforeRender 
called in this case). You'd notice this behavior if the console had a message 
about 'unrendered feedback message'

Re: Specific redirect after session timeout

[Clint Checketts]

Have you tried a HybridUrlEncodingStrategy?

That one is pretty resilient to session restarts.

Re: Forcing parent CSS to be contributed after all child CSS

[Clint Checketts]

I recall reading an article once noting that you could contribute the CSS
file noted in the parent class again in the child component and Wicket is
smart enough to not duplicate the contribution, but it still forces the CSS
file to appear later.

You also may consider changing the parent CSS rules to be more specific or
generic (depending on your intentions), to allow them to cascade.

Re: org.apache.wicket.WicketRuntimeException: No get method defined for class: class java.lang.String expression: userName;

[Clint Checketts]

The error is in the model you gave your form. Since you aren't explicitly
stating a model for the DDC, it is assuming a CompoundPropertyModel on the
parent form.

I suspect your form declaration is something like

 new Form("form",new CompoundPropertyModel(getUserName()))

It should be something like

 new Form("form",new CompoundPropertyModel(new User()))

I'm personally not a fan of CPMs and prefer explicitly setting the model for
each of my components.

Re: Refreshing loadable detachable model object inside an ajax call

[Clint Checketts]

Your issue with the generics is you need to tell it that 'T extends
Indetifiable', or take it out entirely if you are going to explicitly tell
it that you are using the Parent class.

Also feel free to make the argument match what your load method requires.
The article could be referencing code that is old or whatever. Also keep in
mind that the class Long implements Serializable, but the primitive long
(lower case 'l') isn't an object and doesn't have a type inheritance (even
though it will serialize, but that's a disfferent topic).


-Clint



public class EntityModel extends
AbstractEntityModel {
   public EntityModel(Class clazz, Serializable id) {
   super(clazz, id);
   }
   @Override
   protected T load(Class clazz, Serializable id) {
   return WicketApplication.get().get_
service().load(clazz, id);
   }
}

First of all, avoid using a label to generate html. Put the repeater on the

You end up with better markup and java that is clearer to understand.

Re: Refreshing loadable detachable model object inside an ajax call

The 'implicit super constructor' warning means that in your constructor you
need to call 'super()'

The 'complains on type T' part I'd need a little more info. Feel free to
post the exact lines of code.

Have you tried explicitly calling .detach() on the LDM?

The net getObject() call should force the load() method to get called again.

Re: StatelessForm redirect

[Clint Checketts]

The remaining stack trace seems strange. But ignoring that and focusing on
setting the 'action' attribute, in the webmarkup container that you use (in
stead of a form component)

Do something like:

@Override
onComponentTag(...){
  tag.put("action",RequestCycle.get().urlFor(SearchResultspage.class))
}

Its hacky but would work. Probably want to make sure you've using
method="get" on the form too.

Re: StatelessForm redirect

[Clint Checketts]

Ah, the trouble is in your NPE:

java.lang.NullPointerException
   at index.AbcPage.validateParams(
AbcPage.java:258)

As long as that exception remains unhandled, the pages won't hand off. The
Form has to resubmit back to the page the form lives on since that is where
the form listener is waiting.

If you feel confident and wish to totally bypass wicket's form processing,
instead of a Form you could use a WebMarkupContainer and in the
onComponentTag set the Action attribute to the page you want to redirect to.
I did something similar long ago when I was first learning Wicket. I don't
recommend it, but it is a possible solution.

Re: StatelessForm redirect

Wicket uses a 2 step render :
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/settings/IRequestCycleSettings.html

Have you tried using setRenderStrategy(ONE_PASS_RENDER ONE_PASS_RENDER) in
your application?

Re: Set all form fields to output markup id automatically

[Clint Checketts]

If this is specific to a particular form you could use A formcompoment
visitor to iterate over each child and call setOutputMarkupId

Re: Page to select something and use the selection in another page

Could the second page be a modal window? Or do you require that it is
a separate browser window?

Wicket Cookbook Questions - ConversionExceptions (pg 30)

[Clint Checketts]

I'm really enjoying Igor's Wicket
Cookbook(hooray
for ebooks and instant delivery!)

Instead of asking Igor directly, I figure this mailing list is a better
forum.

There is an example (page 30) like the following:

ConversionException e = new ConversionException(
"Error converting value: " + value + " to an instance of: "
+ Time.class.getName());
*e.setSourceValue(value);*
e.setVariable("inputPiece", value);
e.setResourceKey(getClass().getSimpleName() + "." + errorKey);

My question is the purpose of 'setSourceValue()' call. I suspected it was to
leverage the converted value in validation messages, but ${input} already
has that value. Next I figured it could be used for the sub piece of a
conversion, like in parsing a time of day (11:15am) then is the minute
section was wrong (11:99am) the it would expose that specific value, but
setVariable() meets that need:

e.setVariable("inputPiece", value);

The previous line makes ${inputPiece} available in Validation messages.

So what does setSourceValue() do?

Wicket mentioned at Server Side Symposium

[Clint Checketts]

Take the following with a grain of salt since I was told by a friend, of a
friend that attended the Server Side Symposium last week. I don't have any
of the details either so bear with me.

Apparently in a session related to 'corporations using open source' the
speaker asked if any companies were using Wicket. He cautioned that Wicket
was an example of mis-managing by being known to break it's APIs in minor
point-releases.

In my experience with the Wicket API, I've only seen major API changes in
the major releases: 1.3 -> 1.4 and the upcoming 1.5. (In my book API *additions
*like adding onConfigure don't count) So of course I stood up for Wicket.
Even when I've proposed changes myself the core developers have done a great
job of not breaking APIs.

So, does anyone else know what this speaker may have been referring to
regarding API breakages?

Re: Replacing markup generated by a Behavior

[Clint Checketts]

Elegant! I'd been trying to think of ways to add my own markup ID and
piggyback off any render requests that redraw the component to trigger and
render the feedback, just using the component markupId will work great!

Instead of setOutputMarkupId(false), I'll detect that to decide to add the
ID or not and just remove the ID attribute in the onComponentTag() method.
I'll code it up tomorrow. I've got a good feeling about this.

Thanks for the help. Also I'll check out the IAjaxRegionMarkupIdProvider.
Always good to check out the new interfaces.

Replacing markup generated by a Behavior

[Clint Checketts]

I have a Visitor that iterates through my forms and adds a Behavior that
writes out to the Response a  and any feedback messages that belong to
that component. This is really great because it gives me inline feedback
panels. Here is the problem: if the component is ever updated via ajax, the
component the behavior is tied to get replaced in the DOM, but the feedback
messages get written out in another  again.

My core need is to create some sort of auto-adding inline feedbackpanel.

Any good recommendations on how to work around this? It's such a good design
pratice to have error messages next to the offending input fields, I'm sure
others have had to deal with this.

Re: How can I reload HTML in app engine?

MyWebRequestCycle(final WebApplication application,

super(application, request, response);
}

@Override

if

{

(GaeModificationWatcher) getApplication()
.getResourceSettings().getResourceWatcher(true);
resourceWatcher.checkResources();
}

}

Conditional Validation (Save versus Submit)

[Clint Checketts]

I have a form with 2 buttons: Save and Submit. If the user hits Save I want
to bypass my validations, but still update the underlying model objects so i
can persist them in a partially completed state, then have the full
validation run when the Submit button is clicked.

If I call setDefaultFormProcessing(false) then the underlying model isn't
updated either, right? This seems like a pretty common issue, has anyone
else implemented a genius way of dealing with save/submit logic?

Thanks,

Extending RequestLogger

[Clint Checketts]

I'm trying to implement my own RequestLogger but have hit a snag. As an
initial implementation i just copied the existing RequestLogger completely
(instead of extending it) and am editting it to do what I need.

There are 2 snags that I have run into:

1) SessionData and RequestData are inner classes in RequestLogger and the
IRequestLogger interface requires the getRequests() to return a
List (meaning the inner class to RequestLogger).  I could work
around it if the interface said List instead of that
specific RequestData.  Could the interface's generics be updated to allow
for that? Is there a way that I can 'override' the interface?

2) In SessionData addTimeTaken(long time), setSessionInfo(Object
sessionInfo), and setSessionSize(long size) are declared without public or
protected. SO i am not able to override them (or call them from my custom
RequestLogger). Is that an oversight? Shouldn't those methods be 'public'?

Let me know if you require me to open tickets or anything to fix these.

I'm still new enough to this that I'm not certain if these are bugs or
features.

Re: How to write markup if type of component is not known yet...

[Clint Checketts]

I use the AjaxEditableLabel and related components and I've subclassed them
overriding the onBeforeRender adding a call that checks if it should be in
edit mode, then its just a matter of setEnabled(false) to keep the
AjaxEditableLabel as a label.

Re: WebRequestCycle is creating a HTTP 400/Bad request

[Clint Checketts]

I've been hitting a similar bug with MixedParamUrlCodingStrategy and
Stateless forms. I haven't had a chance to create a sample yet so I just
changed encoding strategies for the time being.

I believe your bug is similar to the one I''m hitting. I'm using Wicket
version 1.3.7. I'll try to post a simple case to see if it really is
identical.
