Re: AjaxLazyLoadPanel, nothing else works until it finishes loading
The page will block until the panel is loaded. There are a number of threads discussing this. Here are a couple of gists that allow panel content to be loaded in an asynchronous manner in another thread, thus making the UI appear non-blocking. https://gist.github.com/594468 https://gist.github.com/636875 hope you find them useful.

Re: JFreeChart with clickable imagemap
Hi, A little late maybe but since I wrote that wiki page I've improved the code to use models and so be responsive to data changes.

Re: Generics and SortableDataProvider
Hi Sven, Thanks for your reply. Since I sent the original question I ended up doing what you suggested and now I'm wondering why I ever used the id projection approach. Habit I guess, formed with previous frameworks. Just to make sure I've got this right, as long as I use a DetachableModel as a return from model method, the domain objects aren't stored in the session even if they are returned from the iterator. Am I correct in this? Jonny svenmeier wrote: Hi John, I believe the consensus on this list is that you should change your approach: Why don't you just iterate over your domain objects in the first place? They will be loaded anyway to be displayed on your component. So your approach triggers 1+n selects instead of 1 select for all required objects at once.

Re: JFreeChart component
I looked around wicket stuff and didn't see anything related to JFreeChart. If you think it is suitable for inclusion in wicket-stuff, or elsewhere, then by all means upload it. It's only four classes so I don't think it is worth creating a new project for, and I don't know where it would fit right not.

JFreeChart component
Hi, I recently developed a component that displays a chart generated from JFreeChart and includes the associated image map that allows the chart to generate tooltips and respond to user clicks, via an Ajax link. I thought this maybe useful to other people so I've included the files here. To use simply construct the MappedChart with you JFreeChart and provide an implementation of the onClickCallback function to respond to user clicks.

Modal window and resource request target
Hi,
I have the situation in which an action applied to a specific object needs
to obtain some information from the user then construct a dynamic resource
(pdf file) based on the object and obtained information.
The list of object are contained in AjaxFallbackDefaultDataTable and I am
currently approaching the problem by using a modal window to obtain the
extra parameters when the user clicks a specific AjaxFallbackLink on a table
row. This works fine but, when I try and stream the constructed resource
nothing happens. This is the code in my WindowClosedCallback function:
public void onClose(AjaxRequestTarget target) {
if(panel.getNumberOfDays() != null){
System.out.println(Visiting resource);
TubeLabelsResource resource = new
TubeLabelsResource(study.getId(),
searchServices);
ResourceStreamRequestTarget requestTarget = new
ResourceStreamRequestTarget(resource.getResourceStream());
RequestCycle.get().setRequestTarget(requestTarget);
}
}
any pointers as to how to get the resource to stream in the onClose, or an
alternative approach to the problem would be gratefully received.
thanks
Jonny

Re: IllegalStateException with AjaxFallbackDefaultDataTable
Antoine, I actually approached the problem from a different direction in the end and avoided this error. But, before I did that I tracked it down to calling super.onSubmit call in the overridden onSubmit method of the AjaxEditableLabel.

Re: IllegalStateException with AjaxFallbackDefaultDataTable
Hi Igor,
I was hoping it would be an obvious problem. Here's my table construction
code (is there a better way of posting code?)
ListIColumn columns = new ArrayListIColumn();
PostOnSubmitAction peptideUpdateAction = new PostOnSubmitAction();
columns.add(new AjaxEditablePropertyColumn(peptideUpdateAction, new
Model(Comments), comments, comments, REQUIRED_ROLE));
PeptideDataProvider dataProvider = new PeptideDataProvider(service);
peptideViewTable = new AjaxFallbackDefaultDataTable(dataTable, columns,
dataProvider, 25);
where the PostOnSubmitAction below is called from the onSubmit method of the
AjaxEditableLabel within the AjaxEditablePropertyColumn. I'm attempting to
refresh the table when an OptimisticLockingFailureException occurs (and so
load the data altered by another user).
private class PostOnSubmitAction implements
AjaxEditablePropertyColumn.PostOnSubmitAction{
public void postOnSubmit(AjaxRequestTarget target, Object value) {
target.addComponent(getStatusPanel());
Peptide peptide = (Peptide)value;
try{
peptideServices.updatePeptide(peptide);
}
catch(AccessDeniedException e){
String message = You don't have permission to perform
this operation;
PeptidePage.this.error(message);
}
catch(OptimisticLockingFailureException e){
String message = Another user modified this data
before you. Review the

Re: IllegalStateException with AjaxFallbackDefaultDataTable
Igor,
thanks for the help, I'll have to look at in detail next week.
What is odd to me is that I'm not doing anything out of the ordinary. I add
the table to the ajax target, and I don't remove any components myself.
Jonny
igor.vaynberg wrote:
hm, i still dont see the problem spot
the error is apparent
you are adding something to the ajax request target that is then
removed from the page, so when ajaxrequesttarget is trying to detach
the page it cant, because it does
component.getPage().detach();
apparently the component is removed from the page, so getpage() throws
that error you see.
if i were you i would set a breakpoint at that line, and see what
component exactly is removed from the page, and then try to figure out
why it is removed from the page and yet is added to the ajax target.

IllegalStateException with AjaxFallbackDefaultDataTable
Hi,
I'm experiencing an IllegalStateException (stack trace below) that I can't
get rid of. I have a AjaxFallbackDefaultDataTable with columns made up of an
extension of PropertyColumn that places an AjaxEditableLabel into the cell
within the populateItem. This works great until I attempt to add the table
itself to the AjaxRequestTarget within the AjaxEditableLabel onSubmit
method. I need to force a refresh of the table in a specific situation
(Actually, just the data underlying the table row being edited, but I don't
know a way of doing just that). Even though I get the exception the
behaviour is as expected, in that the table updates. Other components also
update fine and without exceptions.
Any ideas or other approaches that would avoid this error?
thanks
Jonny

Notifying a DataTable that data has changed
Hi, New to Wicket so this maybe some obvious I'm missing and I'd appreciate any pointers. I have an AjaxFallbackDefaultDataTable within a AjaxTabbedPanel backed by a SortableDataProvider that drags data from a database as needed. One column of my table contains an AjaxFallbackLink. This link opens up a ModelWindow by constructing a Panel with the object from the selected row of the table and setting the model window content before showing the window. The panel in the model window contains a form for editing properties of the passed in object, with two AjaxButtons for OK and Close. OK will take the form model object and persist it to the database. All this works great, but I can't see a way of notifying the table, or underlying data provider, that the data has changed and needs to be refreshed. Any pointers on either how to do this or an alternative approach? thanks in advance. Jonny PS. This is my first attempt at using wicket and it's been refreshingly easy to get this far.
