Hi...
thanxs for the comments.
The
two list have different values... validList should be "1,2,3,4" and userList
"6,7,8"... and I need the two results.
My
trouble is the binding, it's real... when I use the binding before response is
send to client, all work fine... my component lists binding with my bean
lists... but when the restoreState is called, the binding break. All list work
like independient lists.
Is a
bad practice store in the state the EL Expresion for redo the binding when
Decode?

Asunto: Antwort: RE: to continue with my Custom Component
Well, you are resolving the valuebinding already in the tag. This should be done in the component itself. This way your component keeps a reference to the binding.
In the Tag you should do something like:
ValueBinding vb = context.getApplication().createValueBinding(validList);
component.setValueBinding("validList", vb);
In the component code you get the value with:
getValueBinding("validList").getValue(context);
Hmm, did you provide a second attribute for the tag to specify the output values? For me it makes no sense to double use the validList binding.
I saw something like selectedList ...
In the decode method you should then so something like:
getValueBinding("selectedList").setValue(context, ---- the new SelectItem[]array ----);
