My surprise came when I found the following error: table wicket:message=summary:myresource trtdspan wicket:id=myComponent/span/td/tr /table org.apache.wicket.markup.MarkupException: Unable to find component with id 'myComponent' in [MarkupContainer [Component id = _message_attr_303]].

The first suspicious thig I noticed here was the _message_attr_303 in the component hierarchy. Digging through the code, I found in WicketMessageTagHandler that this id is given to components with wicket:message attributes and without wicket:id's. So, maybe what's happening here is that the table tag is being assigned a wicket:id and Wicket expects me to add 'myComponent' to the automatically generated _message_attr_303...

Yes, you are right, Wilhelmsen, and that's what Wicket is doing, I understand that correctly. The problem is, when I have a wicket component attached to that table tag. Wicket seems to treat that table as a component, with autogenerated wicket:id, and logically, expects the child components (in markup) to be added to it. I suppose I have to manually model that table into a wicket component (i.e. WebMarkupContainer) in order to be able to add those child components to it and let Wicket process the component hierarchy correctly...

Re: Form, panel and model reuse (newbie)
In reply to (6) and (7):
6) Do your construction in the constructor.
7) If the JFreeChartImage component implementation is the one seen
here: http://wiki.github.com/tita/tita/wicket-jfreechart-tutorial ,
then it needs re-worked, as it only supports a static image. Instead,
the constructor should take a model that returns the JFreeChart, which
should be generated from your data list each time getObject() is called
(e.g. a dynamic model).
Anatoliy Knyazev wrote:
Dear Wicket users,
I'm seeking your advice on designing a small Wicket application. I'm new to
the list, hope I'm not violating any rules with such newbie questions. I've
studied the examples, the sample phonebook app and the mailing list archive
on Nabble, yet I haven't find the best practices for what I'm trying to
achieve. Please feel free to point me to an appropriate example if I'm
asking too much questions.
Basically, I'd like to have one form, used to search POJOs, shared
by several pages, each showing the set of POJOs in a different way, e.g. as
a number of JFreeChart images, as a ListView with limited number of items,
as a DataView with paging.
The Form seems pretty straightforward:
public class TasksFilterForm extends FormTasksFilter
{
public TasksFilterForm(String id, IModelTasksFilter tasksFilterModel)
{
super(id, new CompoundPropertyModelTasksFilter(tasksFilterModel));
add(new DateTimeField(beginDate));
add(new DateTimeField(endDate));
/*skipped the rest of fields
}
}
In order to reuse it, I've created a Panel:
public class TasksFilterPanel extends Panel
{
private IModelArrayListCleoTask tasksModel;
public TasksFilterPanel(String id, final TasksDAO tasksDAO,
IModelTasksFilter tasksFilterModel, final IModelArrayListCleoTask
tasksModel)
{
super(id, tasksModel);
this.tasksModel = tasksModel;
add(new TasksFilterForm(tasksform, tasksFilterModel) {
@Override
protected void onSubmit()
{
tasksModel.setObject(tasksDAO.findByFilter(getModelObject()));
}
});
}
1)I'm passing the IModelArrayListCleoTask tasksModel as the constructor
argument for the panel, is this correct?
2)And what is the most appropriate model for a list of POJOs? Can you show
me an example with an LDM, perhaps? What if I'd like to access it from the
DataView?
3)I'm not using any ORM, just simple DAOs. Which is the most elegant way to
inject them? I've checked the Spring+Wicket entry in the wiki, the approach
described there works for pages, not for panels.
The TasksFilterPanel is in turn used in a number of pages like this one:
public class ClusterPage extends SVAStartPage
{
private TasksFilter tasksFilter = new TasksFilter();
ArrayListCleoTask tasks;
private PropertyModelArrayListCleoTask tasksModel;
public ClusterPage() throws SQLException
{
ArrayListString users = getDB().getCleoUsersArray();
tasksFilter.setUsers(users);
tasksModel = new PropertyModelArrayListCleoTask(this, tasks);
add(new TasksFilterPanel(tasksformpanel, new TasksDAO(getDB()), new
PropertyModelTasksFilter(this, tasksFilter), tasksModel));
add(new TasksChartPanel(taskschartpanel, tasksModel));
}
}
4)Should I hold a reference to the tasksModel and tasksFilter from the
TasksPage (declare it as a field, as above) ?
5)Where should I populate the tasksFilter with default values (e.g. existing
users) - in the page? But then I'd have to copy/paste the code across
pages...
In order to display the POJOs, I've created a Panel that shows JFreeChart
images.
public class TasksChartPanel extends Panel
{
private IModelArrayListCleoTask tasksModel;
private JFreeChartImage cImage;
public TasksChartPanel(String id, IModelArrayListCleoTask tasksModel)
{
super(id, tasksModel);
this.tasksModel = tasksModel;
}
@Override
protected void onBeforeRender()
{
super.onBeforeRender();
ArrayListCleoTask tasks = tasksModel.getObject();
IntervalXYDataset ds = ... /* produce a dataset from tasks */
JFreeChart chart = ChartFactory.createScatterPlot(/* plot parameters */)
if (cImage != null) remove(cImage);
cImage = new JFreeChartImage(cImage, chart, 1500, 550);
add(cImage);
}
@Override
public boolean isVisible()
{
return tasksModel.getObject() != null;
}
}
6) I don't have a solid understanding of the request cycle yet, so I'm
doing all the processing in the onBeforeRender - is this correct?
7)With this approach, I have to manually remove and re-add the image every
time the set of POJOs changes - perhaps Wicket can take care of this, I just
didn't find a way?
That's it for now, I've tried to pinpoint the questions and not be too
vague.
Thank you in advance!
Anatoliy.

Re: AjaxFormComponentUpdatingBehavior breaking wicket's convention ? Which alternatives then?
I use it all the time.
In order to get the cancel button and back buttons to work, I do of these
things:
1) I back my model with an evicted hibernate proxy, and I only save the proxy
when the user submits the form. Therefore any change made to the model are
transient unless i specifically persist.
2) I back my model with a custom model object specifically for the form, when
the form is submitted I copy the values to my persisted object. If they hit
cancel then I reload a new model object, or clear the current one...

submitted.
However, the AjaxFormComponentUpdatingBehavior completely breaks this
important aspect, by going directly at the model. Furthermore, the javadoc
doesn't illustrate how dangerous it is. For example, setting
setDefaultFormProcessing on some cancel button won't work anymore. Neither
does the javadoc hint at some ways to avoid this.
Among the way to avoid this, I currently mostly see the
AjaxFormValidatingBehavior or writing an ad hoc form component copying his
initial state and implementing IFormModelUpdateListener.
Thinking back on my initial issue, a Behavior which would only update the
input of the component would have been resolved it (issue was a listview
where adding a line would loose non submitted input on textfields).
A such AjaxFormComponentConvertingBehavior is in fact easy to do, it's a
copy of AjaxFormComponentUpdatingBehavior with a shortened onEvent:
@Override
protected final void onEvent(final AjaxRequestTarget target) {
final FormComponent? formComponent = getFormComponent();
if (getEvent().toLowerCase().equals(onblur) disableFocusOnBlur())
{
target.focusComponent(null);
}
try {
formComponent.inputChanged();
onUpdate(target);
} catch (RuntimeException e) {
onError(target, e);
}
}
Such a behavior would resolve some of the use case currently wrongly
addressed by the AjaxFormComponentUpdatingBehavior. It could even be its
parent class and be spoken of in its javadoc.
What your feelings on that ?
sorry for this long post and thanks in advance for your answers (which most
likely will show I've missed something obvious there!).

Re: DataView disappearing after AJAX update
Just some questions... How does DataView's dataProvider get's affected
by the code on onUpdate? Does getDataProvider(params); recreate it?
Then the instance stored on DataView is different from the one you
retrieve with getDataProvider(params)? Why not implement a
SortableDataProvider, keep a local copy of it, pass it to DataView and
update it's sort state on the onUpdate method?

Replying to myself.
I've worked around the problem by not using the AJAX method to update my
DataView but by reloading the page with different pageparameters after a
selection instead. Far from ideal, but the best I could come up with.
Alternative solutions still welcome!

I'm having trouble figuring out the following problem.
I have a div (coupled to a WebMarkupContainer) containing a form and a
list. The list is populated with a DataView, which gets its data from a
SortableDataProvider that I have implemented according to the repeater
examples provided on wicket-library.com.
What I want to do is to change the sort order based on a user selection
from a DropDownChoice in the form. I've used an
AjaxFormComponentUpdatingBehavior to listen to the dropdown's onchange
event. In the onUpdate() method I change the sortparam in the
dataprovider according to the selection and then add the container div
to the AjaxRequestTarget.
What I expect to happen is that the DataView updates to reflect the new
sort order. What actually happens is that the DataView completely
disappears from the page! (The Wicket Ajax Debug window shows me that
the spot where the list should be in the HTML within the ajax-response
is indeed empty.)
I've already set the outputmarkupid and the outputmarkupplaceholdertag
properties on the container to true but that makes no difference.
Any ideas are appreciated!

Re: Any indicator for Ajax-Rendering?
Yeah you're right... but i think i have to describe my problem i another way.
I have two linked DropDownBoxes and i want intially on Page-Rendering that
the second (child) drop downbox is filled by the initial value of the first
box.
the linking is done with my own onChange handler
protected void onChange(AjaxRequestTarget target, T newSelection){ };
the best would be, i could use this handler for initial rendering and
ajax-onChange, cause there i've implemented the processing of filling the
second drop down box By newSelection!
Thanks for any Hints!

Re: GAE serialization issues
I can only say that I've been using Wicket on GAE for awhile and it seems to work pretty well, with some extra effort. For now, I'm just using HttpSessionStore. I asked in the GAE forums about the performance there and they said session storage made heavy use of the MemCache to keep performance strong. It is possible that Wicket can store very LARGE objects in the SessionStore, but that may be an indication of poor page detaching. After making that improvement, my session data rarely exceeds 100K. I may try out a pure MemCache version based on the link you provided, see if I can get it lower and less dependent on the session. The only other serialization issues I've noticed deal with changing model objects across requests - I instead am forced to replace components on occasion, instead of replacing model objects. That's a hack right now and I'll look into it later. Don't know anything about JBoss.

Big Problem with TinyMCE
I'm trying to use a TinyMCE editor on a form (itself belonging to a panel added to a page via Ajax). The form is submitted via an AjaxButton. From other posts here and elsewhere I found I had to call tinyMCE.triggerSave(true,true); before the submit to get the data into the textarea's model and then tinyMCE.idCounter=0; after the submit. I used an IAjaxCallDecorator to add these functions to the submit button. The problem is that the form only submits with every other press of the button. When it fails, it looks like no script appended after the triggerSave runs. Can anyone help me out? I'm stuck. Thanks, Brad
Re: Strip header contributors from Ajax response.
Good Afternoon, I've working on this theme, and I found a solution to avoid the strip of our resources. On the Ajax Behavior, we put this lines: ResourceStreamRequestTarget targetRes = new ResourceStreamRequestTarget( new PackageResourceStream(MyScopeClass.class,resources/myJS.js)); targetRes.setFileName(MyJS.js); RequestCycle.get().setRequestTarget(targetRes); And, this way, we can still using our resources redered with the HeadersConstriburtors -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Strip-header-contributors-from-Ajax-response-tp2019993p2076267.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
AjaxFallbackDefaultDataTable Model Not Updating
A co-worker of mine created an AjaxFallbackDefaultDataTable with editable cells. In this case they are dropdowns. She is dynamically adding rows to the table. If she modifies one of the component drop down (PropertyModel) values in one of the cells and then adds a new row, the changes she made to the previous row(s) are lost. She noticed that the setter method on the property is not called, but the getter is being called. I'm pretty sure that if she submits the form the model would get updated (normal form processing) and her changes would be persisted to the model, but how can she get the model to update without submitting the form? I seem to remember previous forum topics related to this issue, but couldn't remember the suggested solutions. Does the solution have to do with selecting a different ItemReuseStrategy? Thanks, J.D.
