Subject RE: JavaScript and Dialog Framework
Date Thu, 26 Oct 2006 08:10:33 GMT
Hi I have successfully launched a dialog from a javascript.  I can get the
correct FacesContext objects.  Problem now is how do I setup a
returnListener for the Dialog.  The Dialog is launched during an onblur
event of an InputText.  So I'm planning to extend the CoreInputText
component and implement it as a DialogSource. Do you have any suggestion on
where can I start doing this? What are the steps needed?

Yes, I know, if only the component was an ActionSource, then things would be
a little bit easy.

Actually that will work only if your component launching the dialog isan
ActionSource, as I mentioned in my first replies.
