Hi,
what is the recommended way how to deal with optional attributes that refer
to a method expression?
For example imagine a simple component that uses a commandLink and has two
attributes: "action" and "actionListener":
<cc:interface>
<cc:attribute name="action" method-signature="java.lang.String action()"
default="???" />
<cc:attribute name="actionListener" method-signature="void
actionListener(javax.faces.event.ActionEvent)" default="???" />
</cc:interface>
<cc:implementation>
<tr:commandLink action="#{cc.attrs.action}"
actionListener="#{cc.attrs.actionListener}" />
</cc:implementation>
My problems:
1) omitting the defaults results in NullPointerExceptions
2) the spec says that a default-attribute must evaluate to a
java.lang.String
What is the solution for this simple problem?
Thanks in advance.
