[jboss-user] [JBoss Seam] - Can't pass action successfully to custom source tag
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:
javax.faces.FacesException: Error calling action method of component with id
loginForm:loginButton

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.
