Multiple actions with ajax4jsf commandLink or commandButton

[carlpritchett]

How can I use an ajax4jsf commandLink or commandButton do more than one action?

E.g. I want to populate a value in a bean using the expression language and also set a variable that other components will use to decide whether to render.

What is the most appropriate way to do this in seam?

Do I have to resort to a backing bean or is there a better way?

Regards,
Carl.

I have the same problem.  I need to execute more than one action within a a4j:commandlink tag.  What is the best way to proceed ?

Thank you.

You can either use pipe or fluent api, for example:

Class A {
   public B firstAction() {...}
}

Class B {
   public C secondAction() {...}
}

Then you can use #{A.firstAction.secondAction}

Or use @RaiseEvent() & @Observe to do the trick.
