Hi David, thx for the help. Strutz TreeView looks nice, but in my organisation we don't want to implements another ad-on to Jetspeed. This forced me to make my own TreeView...
I understand the Actions of Turbine, but the Problem is, that i don't have any Button to execute the action. In ECS (equals in Velocity) i have an image like a folder which must trigger the action. This image is placed by an IMG-Tag, where i can't add any action on the way like on buttons, because i only have a href Attribute. I knows that the developer of Jetspeed uses in a special way that i can't review the href-Attribute to link to the Action like $Action.link (U can see it in the menu-tab.vm of the control). The Problem i have, is that i don't know how this link is used as a reference to a real JAVA-Action-Object...

This looks cool, not sure if its part of Jakarta Struts or add-on http://struts.application-servers.com/tags/treeview.html Do you know about Turbine actions in Jetspeed? http://jakarta.apache.org/turbine/turbine-2/howto/action-event-howto.html http://jakarta.apache.org/turbine/turbine-2/fsd.html -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
