Re: ResourceReference for resource in webapp dir
Hi,
I didn't understand why you want to use ResRef but if this is your
requirement then the easiest will be to create your own IRequestMapper
that handles only your own IRequestHandler that works with your ResRef
impl.
IRequestMapper#mapHandler(IRequestHandler) is the one responsible to
create Url when RequestCycle#urlFor() is used.
Also take a look at
org.apache.wicket.util.string.UrlUtils#rewriteToContextRelative()

Hi,
I have the following code in my base page:
public void renderHead(IHeaderResponse response) {
// scripts/jquery-1.7.1.min.js is in webapp dir
response.renderJavaScriptReference(scripts/jquery-1.7.1.min.js);
}
How can I transform this direct URL to a ResourceReference?
PackageResourceReference is not a good fit because I don't want to store the
.js in a Java package since it is used by non-wicket pages.
With ContextRelativeResource, Wicket reads the actual resource and sends the
result instead of simply pointing to a URL.
AbstractResource with its newResourceResponse() abstract method requires to
return the actual ResourceResponse which won't allow for a simple URL.
So from what I gather, I would have to fallback to implementing an
IResource's respond(Attributes attributes) method. I looked at the
implementation in AbstractResource but I'm confused about what to do with
headers since I only want a URL.
So, does this functionality already exist? If not, do you have a few
pointers to steer me in the right direction?
Thanks,
Bertrand

Re: Wicket ResourceFinder implementation for resources modified at runtime
Hi, On Fri, Feb 3, 2012 at 5:21 PM, Santha Kumar santhakr.t...@gmail.com wrote: I am using wicket 1.5.2. I have implemented a custom IResourceFinder that locates my wicket template [HTML] files from say /assets folder. This custom resource finder is registered with the application during application init [getResourceSettings().setResourceFinder(new myCustomResFinder())]. Now I have a situation where the assets are going to get versioned at runtime, which means my lookup path should be something like /assets/1 or /assets/2. I am just looking for a way if someone had a similar situation earlier. There are a couple of ways I think this can be achieved. 1. Listen to the assert version change event in wicket WebApplication and create a new instance of my custom resource finder with the new path, and set it again in ResourceSettings. I think this may be against any assumption that wicket makes that once WebApplication is initialized, the ResourceFinder is not going to change. Does wicket assumes that? Or can I go ahead and change the ResourceFinder anytime I want? This is allowed. The only thing that bothers me is that there is no synchronization when reading/writing the finder and you may experience problems like seeing the old assets after assetVersionChanged event has been fired for some request(s). 2. My custom resource finder decorates around WebApplicationPath and adds the path to the decorated WebApplicationPath instance - I have to decorate this as I determine the path within this resource finder component. Now I can listen to the asset version change event in my resource finder but I won't be able to overwrite the existing path in the WebApplicationPath. WebApplicationPath maintains a private final list of paths. If I need to do this way, I will end up duplicating the WebApplicationPath code in my custom resource finder, which I am not really comfortable in doing. I think you may use org.apache.wicket.util.file.Path instead of WebApplicationPath. And I think WebApplicationPath should extend Path because now they share common logic... Has any one tried this?

Re: Communication (in-vm) between webapps
I agree a messaging queue is a nice scalable system. But I also think pragmatic approaches are best. You don't have messages that need to be sent right now (data sent between disparate apps). You have a single command that needs to be invoked. That happens to be what HTTP is *really* good at. And, you're already writing a web app. That said, I'd choose Serban's recommendation. Create a Wicket bookmarkable page that takes a pre-shared key or some other method of authentication and call that from the app. If it's just an encrypted URL param that gives authorization you don't even need to call it from the other app - just give the user a link to click that goes straight to the flush cache page on the frontend. Open that in a new window, have your page print out all your strings are belong to us and you're done :) -- Jeremy Thomerson http://wickettraining.com *Need a CMS for Wicket?

Hi Dan,
Yes I never really liked my item.setModel() technique, just didn't seem
right to me but I've seen it in more than one tutorial so I figured it
was the way it was done. I actually moved the compounding part over the
newItem method in dataview just now though, seems cleaner.
populateItem(ItemPost item) {
item.add(new ProductPanel(product, item.getModel());
}
ProductPanel(String id, IModelProduct model) {
super(id, CompoundPropertyModel.of(model));
add(new Label(name));
add(new Label(condition));
}
I'm sure this would work, just wondering if there's a better way to do
this? Is it good practice to manipulate the model in the constructor
like that? Doesn't seem right to me as the model may need to change
(maybe via ajax?). I try to never mess with my models like that outside
of the rendering phase. I've been toying with wicket occasionally for
over a year now, but never gone this far with it so I'm still learning
how it all works.
I would if at all possible like to retain the ability to create a new
ProductPanel without specifying the model in the constructor. This seems
to be the way things are usually done in Wicket so I figured there must
be a better way.
Product is a property of post so I'd be specifying it in two different
places, and again if I wanted to add any more composited components
under ProductPanel.
I've corrected your code to reflect this (I just got your next message).
populateItem(ItemPost item) {
item.add(new ProductPanel(product, new
PropertyModelProduct(item.getModel(), product));
}
I was using the compoundpropertymodel to avoid specifying the product
property manually as is done above, but that part is working for me with
no issues, it's just inside ProductPanel that I'm having problems.
It's not that I'm really that lazy, just an issue of best practice for
me.

Hi guys,
I'm having an issue with property models.
I have a DataView running over a number of Post objects. The Post

has a property named product with appropriate getter/setter.
new DataViewPost(posts, provider) {
protected void populateItem(final ItemPost item) {
item.setModel(CompoundPropertyModel.of(item.getModel()));
item.add(new ProductPanel(product));
}
}
The issue is within ProductPanel. It has a number of labels, each only
specifying a name (no model). In my initModel() I am creating a
CompoundPropertyModel around super.initModel(). I was expecting it to
pull these properties from the model object of my ProductPanel.
public class ProductPanel extends GenericPanelProduct {
public ProductPanel(final String id) {
add(new Label(name));
add(new Label(condition));
}
protected IModel? initModel() {
return CompoundPropertyModel.of(super.initModel());
}
}
But I get this error: org.apache.wicket.WicketRuntimeException: No get
method defined for class: class com.cellcycleusa.domain.Post
expression:
name.
Seems that it's trying to access the Post object from the DataView to
pull the property from, not the model object of the ProductPanel
itself.
Now the really funny part is that if I just add this to ProductPanel,
everything works fine:
protected void onBeforeRender() {
getModel();
super.onBeforeRender();
}
Or if I specify the model objects for the labels within ProductPanel
like this:
new Label(name, new ComponentPropertyModelString(name))
That works as well.
What am I doing wrong?

My end users (web newbies) have found another interesting way to confound the most clear and straightforward instruction I can devise regarding it's (obvious?) use. I watched an end user type an entire time into the hour component without tabbing over to the minute. So, I'd like to suggest a minor change to extensions.yui.calendar.DateTimeField.html to add the maxlength=2 to the current size=2 on the hour/min input controls. I think it might be a simple way to give earlier feedback (I've found it unwise to rely on instructions like Please enter dates and times like this... ). I know I could accomplish this for my own instances, perhaps with a copy of this modified html in a spot higher in the classpath, or maybe an attribute modifier someplace..., but then I thought what is the downside of making it the default? Sure, it would impact a lot of code, but unless some locale I don't know of has 3 digit minutes, I don't think in a negative way --- I was suprised to find no other similar past discussion; perhaps there is some obvious reason this isn't a good idea? I can't be the first one to think of this, can I?

Re: Property Model Issue
I wouldn't necessarily say that CPMs are the wicket way.

I usually try to avoid them, I'm not too fond of runtime reflection, loss of compile time type checking, etc. At the same time though there is something to be said for doing things the conventional way within a framework, and from everything I've seen this is it. I actually figured out the problem. When wicket tries to initModel it searches parent components for their model, but it doesn't use getModel, it uses getModelImpl, which does none of initModel magic.

Setting/changing id for components after creation.
I have a panel which adds another child panel created by other users. The problem for me is that the parent panel expects the child panel to have a particular id (formPanel). The child panel will itself be a derived class and will have a corresponding wicket:extend html file. Since there is no setId(String id) method provided, what will be the best way to handle this problem? I had thought of creating derived child panel classes with the required id set by the derived class itself. The user will create another derived class off former class ... but this just ends up with way too many classes depending on future parent panels, etc. I hope I have not made it too complicated to understand.

Re: Wicket-Source: Click-through from browser back to Java source
Wicket-source 1.5.0.7 is available now as a full release in maven central. This fixes a bug where ajax components were skipped; should work solidly now in all cases. If you have a bug report, there's an issue tracker on the github project site. https://github.com/42Lines/wicket-source I also backported for wicket 1.4.x compatibility and that is available as a full release in maven central now. Version numbering is (wicket_version).(my_version). Jenny Brown
