    Can't pass action successfully to custom source tag

    Steve Antonakakis Newbie

      Hi,

      I was debating whether this was a facelets or Seam question:

      I've created a custom commandLink tag and I'm using it in a seam pageflow. The id & value attributes are passed successfully but the action attribute is not. Here are the pertinent code segments:

      bdex.taglib.xml
      . . .
      <tag>
       <tag-name>commandButton</tag-name>
       <source>tags/commandButton.xhtml</source>
      </tag>
      . . .
      
      tags/commandButton.xhtml:
      . . .
       <h:commandLink id="#{id}" action="#{action}" value="#{value}"
      styleClass="bdexCommandButtonLink" style="font-weight: bold; #{style}" />
      
      client file - login.xhtml:
      
      <bdex:commandButton id="loginButton" value="Login" action="login-user" />
      
      


      The following errors are reported in the log once the button is clicked:

      Any help would be greatly appreciated. I'm new to Seam/JSF/Seam so I apologize if this turns out to be a trivial issue.
