Hi Jakob, I wanted to design the following composite component (a panel with two buttons):
<my:buttonPanel button1="#{myBean.button1}" button2="#{myBean.button2}" /> where "#{myBean.button1}" and "#{myBean.button2}" are instances of SimpleModel. For the button expression should apply: If it evaluates to null the button is disabled, if not SimpleModel.myaction() will be executed. Therefore I wanted to express with the following composite component attribute declaration: <cc:attribute name="button1" type="SimpleModel" > <cc:attribute name="myaction" targetAttributeName="action" targets="button" /> </cc:attribute> that the attribute "myaction" of the instance maps to the action of the button. I guess that it does not work even with JSF 2.1 because it is a nested attribute declaration. -- View this message in context: http://old.nabble.com/composite-components%3A-optional-method-expression-attributes-tp30067392p30168428.html Sent from the MyFaces - Users mailing list archive at Nabble.com.
