a4j:ajax listener method expression behaves differently for one or zero
parameter methods
-----------------------------------------------------------------------------------------
Key: RF-11125
URL: https://issues.jboss.org/browse/RF-11125
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-a4j-core
Affects Versions: 4.0.0.Final
Environment: MyFace 2.0.7, Tomcat 6, Richfaces 4.0
Reporter: James G
When using a4j:ajax and setting the listener to a bean method, the call works
correctly if the bean method has one parameter of type AjaxBehaviorEvent. If
the method has no parameters then it may not be called correctly. This
situation occurs if the method expression uses a variable scoped in facelets.
For example using a ui:param under a ui:decorate. The method expression for
one parameter is created using a call to
ExpressionFactory.createMethodExpression( faceletContext, ... ) but the method
expression for zero parameters is created using
ExpressionFactory.createMethodExpression( elContext, ... ). The elContext does
not contain the facelet variable mapping and so will not impart this to the
method expression. This needs to be refactory to pass in the faceletContext
when creating the zero parameter method expression.
