Thanks Volker, I figured that out, but still i cannot understand the usage of <from-action>. I needed the above information because i needed to call an action method and then transfer the control the navigation handler programmatically. I was able to achieve the same by first creating a MethodBinding, invoking it, getting the return value as an outcome and passing the same to the handleNavigation method of the NavigationHandler.
It worked for me. ~madhav On 3/3/07, Volker Weber <[EMAIL PROTECTED]> wrote:
Hi Madhav, the action methodBinding is handled in the defaultActionListener, which is invoked also in broadcast() from UICommand.
