comunication between panels
i have a question: how can i comunicate between panels in wicket?
my application contains a frameset of 2 pages, each of these has a
tabbedPanel containing many panels:
----------------structure--------------
APP
PAGE1 PAG2
panel panel panel panel panel panel
---------------------------------------
what is a good solution?
MY solution is to:
1)extends WicketSession and implements get/set methods to retrieve insances
of these panels
2)use it:
Panel donald = ( (MySession) panel.getSession() ).getPanel('donaldduck');
so i can retrieve insance of foo panel everywhere and use its public
methods.
IS A CORRECT SOLUTION?
and then... PUTTING PANELS INSTANCES IN SESSION is a bad implementation
about MEMORY AND wicket SERIALIZATION ?
There is a BEST SOLUTION? that i don't know
Thanks.

Panel A puts the state information in the session during Link.onClick()
Panel B uses Session.getSession() to retrieve the state information during
render()
this simple technique is what i use and its very efficient.

Re: comunication between panels
Posted by Ayodeji Aladejebi <al...@gmail.com>.
panels in session is a bad idea.
Why not just keep the panel state information in the session and then let
them just pull it from there when they instantiate?
By the way, what are you trying to achieve with your panels cuz it is a bad
idea to be stuffing up panels in your session when you can simply keep the
state information the panels need there.
If you instantiate a new Panel, the new Panel can call
getSession().getInformationStateId(), pass that informationState to an
IModel and then the Panel has whatever it needs

But what if you just share the tree instance between the two
pages?

Re: comunication between panels
Posted by Mazzanti Luca <ha...@hotmail.com>.
i don't understand your phrase: 'why are you shouting'
please repeate.
sorry i don' have a very large vocaboulary. But please help me solving this.
the situation is:
on the left i have a page containg a wicket tree. on the right another page
containing a panel.
on click of a node in the tree, i need to send the object in the node to the
panel ( called panel2 ) in the other page, and reload panel with new
informations.
how can i do?
onNodeClick i call my sessision, i retrieve the instance ( that i put into
at panel2 initialization ) of panel2 and with it i call its method
setItem(), then i reload it.
it's correct? i m currently reading about 'Generic inter-component event
mechanism'
at https://issues.apache.org/jira/browse/WICKET-1312

This would be very cool if can be moved to 1.3.x release as well.
This way, it would be possible to address
AjaxRequestTarget#addComponent in a more elegant way.

This patch is almost what I want, cool!
A question though: When sharing models between components, or using
PropertyModels on a shared model, I would like to have onModelChanged
events when something in that model changes. That way Components that
use the model could use the onModelChanged method to add themselves to
the AjaxRequestTarget (using AjaxRequestTarget.get() or
(RequestCycle.get().getRequestTarget() instanceof AjaxRequestTarget) in
wicket-1.2.x). Unfortunalety onModelChanged is only called when a model
or model object is explicitly set on a component.
Is there a way to make this more transparent? I was thinking along the
lines of adding PropertyChangeSupport to all my model objects, but that
would be very laborious. An aspect-oriented solution might do the trick too.
Any ideas?
Matthijs.

The normal Wicket way is to share models, pass references etc,
but it has its limitations.
You can find an example of a push-type mechanism here
https://issues.apache.org/jira/browse/WICKET-1312
though it is done with just one page in mind.

This seems strage to me, I wouldn't put Components to Session.
You might want to step back to think about what it is that
you want to achieve, and maybe post here about the more
general issue. Maybe there is a better solution for your
real case than the panels of different pages communicating
between each other.

Wicket components (including Page) are stateful, you don't
need to do that by yourself. To keep the state you just need
to use the same page instance.

Them same here, just use the same Panel instance and its
state will be stored transparently by Wicket.

Timo

ok i store in session only objects that contain the state of the page, and i
pass it to the model of the page.
what about PageState? i must watch WebPage source to find where is used and
i modify it to load only data that i really need or there's yet an
implementation of this that i can use?
and for a treePanel, if i don't want to reload every time the tree, i can
put the tree-model in the IModel of panel and at panel instantiation time
retrieve the tree-model from session where i store it?
