Hi Christian,
To refer to actions in hrefs use:
<a
href="$jslink.setTemplate("your,template.vm").addPathInfo("action","Acti
onClassName")"><img src="yourpic.png" border=0></a>
This will result that the doPerform Method of the ActionClass will be
called. If you want to call a certain method, the best bet would be to
supply the method in a parameter and the call this method from
doPerform. The Event Driven Submission (eventSubmit_doMymethod) will
only work in submit buttons.
Hope that helps
Kind regards

Betreff: AW: It is possible to refresh Portlets ?
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...
Christian

I believe Struts has a tree view control.
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?
