I have that figured out, I just don't know how to add the attribute to 
each component. I can't add a behavior, since Cannot modify component 
hierarchy after render phase has started (page version cant change then 
anymore) Can I even do this in a behavior?

Re: Adding attributes to child components in a behavior.

2010-04-15 Thread Michael O'Cleirigh

Hi Warren,

The way I normally handle this situation is to create a javascript 
emitting behaviour that is attached to the container.  This behaviour 
will emit the necessary javascript method to do what you need to do.


Then for each child component you can use an AttributeModifier to write 
their onclick callback to call the custom method being emitted by the 
container attached behavior.


All the logic can be handled in the implementation details of the custom 
method/Object that was emitted.


To get the onclick actions emitted before the rendering phase either 
include it within the container.onBeforeRender() method, to call the 
visitChildren method,  or perhaps within your behavior override the 
AbstractBehavior.beforeRender(Component c) method.


I've written something like this for a table of check boxes where each 
column header is a radio button.  Selecting column 2's radio button 
causes all of the check boxes in column 1 to become disabled and all the 
check boxes in column 2 to become enabled.  In my case I made the 
behaviour aware of the components in each column and then during 
rendering the javascript it writes out an array of markup id's for each 
table column.


But if you don't have the child components in scope when adding the 
behavior to the container adding the child behaviors before rendering 
starts should let things work.


Regards,

Mike






I have that figured out, I just don't know how to add the attribute to 
each component. I can't add a behavior, since Cannot modify component 
hierarchy after render phase has started (page version cant change 
then anymore) Can I even do this in a behavior?

2010-04-15 Thread Cemal Bayramoglu
I assume you were trying this in beforeRender of your behaviour, which
as you say is too late.
If you really need to use a behaviour encapsulate all this, try
something like the following, but some may feel its a little
politically incorrect to do this in bind.
class MyBehaviour extends AbstractBehavior{
@Override
public void bind(Component component) { 
if(!(component instanceof MarkupContainer)){
throw new RuntimeException(contaıners only 
please);
}
visitChildren(new IVisitorComponent(){
@Override
public Object component(Component component) {
component.add(new 
SimpleAttributeModifier(class,goodChild));
return IVisitor.CONTINUE_TRAVERSAL;
}
});
}
}

Re: Adding attributes to child components in a behavior.

2010-04-15 Thread Cemal Bayramoglu
... and if you're not building your component tree before you add such
an IBehaviour to the parent container you can instead override
onBeforeRender on that container to do something like:

@Override
public void onBeforeRender() {
super.onBeforeRender();
visitChildren(new IVisitorComponent(){
@Override
public Object 
component(Component component) {
component.add(new 
SimpleAttributeModifier(class,goodChild));
return 
IVisitor.CONTINUE_TRAVERSAL;
}
});
}

Re: Adding attributes to child components in a behavior.

2010-04-15 Thread Jeremy Thomerson
Yes, this is risky.  Why not add the appropriate onclick handler via JS on
the client side?  i.e., you could output javascript (jQuery in this example)
that says:

$('#myTableID tr').click(function() {
  // do whatever your onclick should do
});

That's just another option - not necessarily the best way either.
