Thanks Eduardo! I managed to get the modal shown, following your hint. But
taking a closer look, I realize I have new challenges to solve:
- currently (and I believe I saw it in wicket 6 also) the
getWindowOpenJavascript() script generates a new div element in the DOM,
with a form inside, when it
Trying client-side now.
In the meantime, for clarity: I need a form with checkboxes and a dropdown
be submitted. The sequence should be:
1) select desired checkboxes in the page,
2) click a button and show a modal window with the dropdown,
3) select the option from the dropdown,
4) click an
Hi.
I need guidance on how to achieve the following: there is a page in my
application that has a StatelessForm with several Checks. The checks allow
to select rows in a table to be deleted when the form is submitted. Now the
customer had requested to have another button that when clicked, a modal
Thanks Sven, I'll have that in mind.
Do you think there are other options? It sounds to me I would not be
exploiting the framework too much in that case (I would have to take care of
the hiding, modal-like appearance, etc?). Thanks

Makes sense. In that case, Sven, how can I have a modal window rendered
before hand so I can hide/show as needed, something like an ajax-less modal?
I wouldn't like to duplicate the effort of rendering a modal window myself.
Any idea?

Thanks Eduardo! It looks like what I need!! But when trying to go step by
step, trying the OpenOnLoadModalWindow as-is, I get the following exception:

Martin, I've implemented my own webmarkupcontainer object and I write the
html in the onComponentTagBody() method. It works super fast. Now my
question is, how can I reuse other components I created (labels, etc) from
within this method? I'm still not familiar with the order of calls, sorry.

new instance is the way to 'refresh' the panel. But my question is where do

Sebastien, Ernesto, I had to repost because after centralizing the ajax
behavior I saw the browser does not send CheckBox ajax requests in parallel
any more. Is this because we centralized the behavior?

Hi, in the project I work on there is a matrix that grows in both dimensions.
Currently it is implemented as 2 nested DataViews. I'm seeing the inner-most
dataview's onBeforeRender() takes 2-3 seconds to process 200 checkboxes,
which if I combine it with a 15 outer-most dataview gives me the
Hi Martin, yes I did some profiling focusing on my classes. I'll post the
results shortly. In the meantime, is there any preference between 2 nested
dataviews vs datatable when table has dynamic number of columns, considering
performance as driver?

Hi Sebastien, I applied your last approach and I think it would work. It is
working but step 4 Get the component back is not finding the checkbox
because of (what I believe) an incomplete path. It doesn't sound
complicated, I'll investigate. However I am starting to understand things
more due to
Hi Ernesto. We seem to be in the same page now. Sebastien's approach is also
about a single behavior, with the small difference of adding the CheckBoxes
onclick event in the server side (I did it in the onComponentTag method
instead of relying on attributemodifiers because of performance) rather
Hi Sebastien, just to understand, if I don't need an AjaxCheckBox anymore
then I shouldn't extend from it right? I'm in troubles, cause if I dont
extend, I have no behavior to call back, and if I do extend then the
original problem arise about the inline onclick script being attached to
each
Thanks Ernesto and Sebastien! I'm going to apply your suggestions during the
weekend and keep you posted. In the meantime, Ernesto, I want to clarify
that I don't want to pass any additional parameter to the server. I just
want the proper onUpdate() method of the proper AjaxCheckBox instance be
Hello all, I am working on an application that was built with Wicket 1.4.15.
It has to show a table with an AjaxCheckBox on each cell. Most of the final
html size is because of the inline ajax behavior on each cb (ie 20Mb for a
200x200 table). Leaving aside the fact of rendering big tables (which
Hi Vineet. I knew someone would ask. Lots of components right? Yes, I agree.
The component tree is giving us a hard time with performance in general
(around 5 minutes to process) and stack overflows when serializing, etc. But
focusing back to my original question, unfortunately the business
Hi Martin, I took a look at the post you mentioned, but in that patch the div
node is still being appended to the document.body node, resulting in the
behavior i'm seeing. However I have to admit that appending the new div node
to the placeholder is just a nice to have. A more appropriate solution
Hi Martin, ticket 4472 created
(https://issues.apache.org/jira/browse/WICKET-4472)
But since I'm new to OSS contributions, I didn't attach a patch. Due to the
low complexity of the change I don't think my patch is a blocker for you?
I'll start setting up my env, to be ready to deliver patches in
Done. Made the requested updates to the ticket.

PD: do you think i should create another ticket for the related post I
mentioned above?
