Re: Re: Custom tag
Hi
For that case, in JSF 2.1 a new attribute for cc:attribute was added
called targetAttributeName. For example:
testComposite:compositeActionTargetAttributeName id=cc1
submitAction2=testActionMethodTypeSubmit
cancelAction=#{bean.cancelAction}
f:actionListener for=submitButton
binding=#{bean.submitActionListener}/
f:actionListener for=cancelButton
binding=#{bean.cancelActionListener}/
/testComposite:compositeActionTargetAttributeName
testComposite:compositeActionTargetAttributeName.xhtml
cc:interface
cc:attribute name=submitAction2 targets=submitCancelButton
targetAttributeName=submitAction method-signature=java.lang.Object
action()/
cc:attribute name=cancelAction targets=submitCancelButton
method-signature=java.lang.Object action()/
cc:actionSource name=submitButton targets=submitCancelButton/
cc:actionSource name=cancelButton targets=submitCancelButton/
/cc:interface
cc:implementation
testComposite:actionTargetAttributeName id=submitCancelButton/
/cc:implementation
actionTargetAttributeName.xhtml
cc:interface
cc:attribute name=submitAction targets=submitButton
targetAttributeName=action method-signature=java.lang.Object
action()/
cc:attribute name=cancelAction targetAttributeName=action
method-signature=java.lang.Object action()/
cc:actionSource name=submitButton/
cc:actionSource name=cancelButton targets=cancelAction/
/cc:interface
cc:implementation
h:commandButton id=submitButton value=Submit Button/
h:commandButton id=cancelAction value=Cancel Button/
/cc:implementation
This is an example using two composite components from the test case.
I think it is enough to put targetAttributeName=action, there is no
need to add the method signature, I don't remember well, but I hope
you get the idea.
The problem described with clientBehavior sounds something different.
Maybe one client behavior overrides the other one, but it doesn't
sound like a bug. I don't know the details behind primefaces to say
something about it, my first guess could be check if primefaces ajax
is a real ClientBehavior, or its renderers do something under
curtains, which is possible because after all, in that library you can
add effects using component properties, and that's not possible
without tweak p:ajax and the component renderers somehow. Note I'm
speculating here.

I do have a simular problem with clientBehavor and primefaces ajax tag.
When a clientBehavor is defined in the composite component and in the view
the composite component is used with primefaces ajax then the clientBehavior
is not added to the component but will added with faclet ajax.
Did anyone face this ?
Is there anything to be aware of maybe naming convention of the

Re: Custom tag
Hi leonardo, this example works:
You can try the alternate syntax using targets. For example:
composite:interface
composite:attribute name=action targets=testComponent/
/composite:interface
composite:implementation
h:commandButton id=testComponent value=Press Me/
/composite:implementation
but what about whit this:
composite:interface
composite:attribute name=action targets=testComponent/
composite:attribute name=action2 targets=testComponent2/
/composite:interface
composite:implementation
h:commandButton id=testComponent value=Press Me/
h:commandButton id=testComponent2 value=Press Me 2/
/composite:implementation
Im triying to use the the action attribute
mycomp:test
action=#{bean.myaction}
action2=#{bean.myaction2}
/mycomp:test
this doesnt work (myaction2 never been invoke) i guess because the
name of attribute is action2 an not action, but i already use action
attribute for my first button, how can i resolve this?
I want to have 2 buttons in my composite component, then my 2 buttons
can have action method (using the attributes).
Thanks

Instead use EL, you can use the id hierarchy to locate the component.
In this case, there will not be NullPointerException, because only if
the property is set, the value is assigned. I have tested both syntax
in MyFaces with tons of tests:

Hi i have this:
Simple custom tag:
cc: interface componentType=my_button
cc:attribute name=action method-signature=java.lang.String action()/
cc:attribute name=actionListener method-signature=void
actionListener(javax.faces.event.ActionEvent event)/
/ cc:interface
cc:implementation
h:commandButton
value=Ok
action=#{cc.attrs.action}
actionListener=#{cc.attrs.actionListener}
/
/cc:implementation
Then in my page i do:
mytags:mybutton action=#{myBean.actionMethod}/
But i get a NullPointerException, this is because im not setting the
actionListener attribute, but the thing is that sometimes i need or
only action or actionlistener not both, but i have to provided both if
not i get the nullpointer.
I have to do this, but the listener method is empty in my managedbean,
i only do this for avoid the nullpointer.
mytags:mybutton action=#{myBean.actionMethod}
actionListener=#{myBean.actionListenerMethod}/
how can i avoid this?
Thanks

Assunto: Custom tag
Hi i have this:
Simple custom tag:
cc: interface componentType=my_button
cc:attribute name=action method-signature=java.lang.String action()/
cc:attribute name=actionListener method-signature=void
actionListener(javax.faces.event.ActionEvent event)/
/ cc:interface
cc:implementation
h:commandButton
value=Ok
action=#{cc.attrs.action}
actionListener=#{cc.attrs.actionListener}
/
/cc:implementation
Then in my page i do:
mytags:mybutton action=#{myBean.actionMethod}/
But i get a NullPointerException, this is because im not setting the
actionListener attribute, but the thing is that sometimes i need or
only action or actionlistener not both, but i have to provided both if
not i get the nullpointer.
I have to do this, but the listener method is empty in my managedbean,
i only do this for avoid the nullpointer.
mytags:mybutton action=#{myBean.actionMethod}
actionListener=#{myBean.actionListenerMethod}/
how can i avoid this?
Thanks

Re: Custom tag
you're welcome. Leonardo's approach is the solution, what i proposed was
more like a workaround ;)

Thanks Rafael and Leonardo.
Its very easy with target, this solution is best in my opinion.
Works.
Thanks again

Hi
You can try the alternate syntax using targets. For example:
composite:interface
composite:attribute name=action targets=testComponent/
/composite:interface
composite:implementation
h:commandButton id=testComponent value=Press Me/
/composite:implementation
Instead use EL, you can use the id hierarchy to locate the component.
In this case, there will not be NullPointerException, because only if
the property is set, the value is assigned. I have tested both syntax
in MyFaces with tons of tests:
http://svn.apache.org/repos/asf/myfaces/core/trunk/impl/src/test/resources/org/apache/myfaces/view/facelets/tag/composite/
and it works without problem.

Leonardo Uribe
