<br>WicketForge to work with IDEA 9 because I'm not on IDEA 9.
<br><br>Feel free to submit patches. Right now WicketForge does everything I need
<br>it to do, so unless I start using Wicket more often or it doesn't meet my
<br>needs, I'm not really inclined to spend my limited free time on it.

<br><br>2 things:
<br>1) If you still have the old setup:
<br> Try stopping server, deploying your stuff to it, starting server.
<br> I've had issues with redeploying at runtime (hot deploy) with Tomcat
<br>(which is what Glassfish is based on). This is where Jeremy's advice to run
<br>Jetty is a good idea.
<br><br>2) Make sure that you refresh the form in your web browser before you try to
<br>enter data and submit. Wicket needs to do stuff to that form before you can
<br>submit it and if you keep same browser open between deployments, you are
<br>sending data back to wicket that it knows nothing about, so it blows up with
<br>pageexpired.
<br><br>The fact that you don't get serialization errors in the log (if it wasn't
<br>serialized) is b/c it didn't get that far yet, so problems are elsewhere.
<br><br>Hope this helps,
<br>- Alex.

<br><br>Hi, Jeremy.
<br>No, the log contained only this error...
<br>But to be honest, although it didn't fix the error, your advice is still
<br>valuable, because not all of the classes were Serializable.
<br>And you know what?
<br>I think I'll reinstall my application server.
<br>I used Glassfish 2 before, and this time I tried Glassfish 3, but it
<br>appeared to be a bitch...
<br>It hangs oftenly and operates strangely...
<br>So maybe it somehow messes with the sessions...
<br>I'll install Glassfish 2 back then, when I have more time for this (maybe
<br>tomorrow), and then I'll post the results here.
<br>Thanks for your reply.

<br>> Hi there,
<br>> is JFreeChart your only possible approach? Check out flot integration
<br>> from wicketstuff-core.
<br>> It draws nicer charts and you can update datasets sending json object
<br>> and redraw it by js.

<br>> >>
<br>> >> Look at the source of the DynamicImageResource class. The getResourceState method does something like (sorry for the lame pseudocode) 'if image data is null then save and return value of getImageData else return the previous image data'. So its gonna call your getImageData() method once and save the value. This falls in line with the super class's (DynamicWebResource) javadoc that says:
<br>> >>
<br>> >> very useful for things you generate dynamically, but reuse for a while after that. If you need resources that stream directly and are not cached, extend WebResource directly and implement Resouce.getResourceStream() yourself.
<br>> >>
<br>> >> It has nothing to do with HTTP caching, which it looks like you're trying to solve with your headers, but server-side caching. Anyways... in this case, getResourceStream of WebResource ends up calling getResourceState of DynamicImageResource. All you need to do is is override getResourceState (and therefore kind of overrides the behavior of getResourceStream) of your DynamicImageResource and ensure that it doesn't cache the result of getImageData() and you should be set.

<br>is JFreeChart your only possible approach? Check out flot integration
<br>from wicketstuff-core.
<br>It draws nicer charts and you can update datasets sending json object
<br>and redraw it by js.

<br>>> Look at the source of the DynamicImageResource class. The getResourceState method does something like (sorry for the lame pseudocode) 'if image data is null then save and return value of getImageData else return the previous image data'.

The getResourceState method does something like (sorry for the lame pseudocode) 'if image data is null then save and return value of getImageData else return the previous image data'. So its gonna call your getImageData() method once and save the value. This falls in line with the super class's (DynamicWebResource) javadoc that says:
<br><br>very useful for things you generate dynamically, but reuse for a while after that. If you need resources that stream directly and are not cached, extend WebResource directly and implement Resouce.getResourceStream() yourself.
<br><br>It has nothing to do with HTTP caching, which it looks like you're trying to solve with your headers, but server-side caching. Anyways... in this case, getResourceStream of WebResource ends up calling getResourceState of DynamicImageResource. All you need to do is is override getResourceState (and therefore kind of overrides the behavior of getResourceStream) of your DynamicImageResource and ensure that it doesn't cache the result of getImageData() and you should be set.

<br><br>Basically I just put in <wicket:extend> tag, without any other tags,
<br>into my Child panel.
<br>This basically throws an exception, as expected in the webpage.
<br>I just took whatever markup that is shown in the error and added it to
<br>my Child, thus circumventing my problem of not having my Parent's markup

<br><br>Is there an equivalent of <wicket:super>? This is for people who dont

<br><br>Yes, that is the right place In fact your map looks identical to the one on our registration page.
<br>We're drawing another good crowd for this LWE (around 40 so far, including many of our regulars), so you'll have a good audience to appreciate your talk!

<br>> There is a cool little Jazz cafe at Foyles too, where there'll be a live

<br>>
<br>> The event schedule looks like:

<br>> Lionel Armanet (FR): Announcing WiQuery 1.0: Introduction & Demo

<br>> Alastair Maw (UK): The Al Talk
