hi,
I'm trying to understand how actions can be called from vm templates.
I started from hello-velocity portlet and I created a simple action class
with some actions called from the vm template.
Everything works fine since I don't customize my portlet using the
'customize' option:
after the customization, my portlet seem to be freeezed and actions are no
longer called (it's always called the default doPerform method).
Maybe I'm making a mistake?
Have I to call a method to 'refresh' my portlet?
follows my action code:
---------------------------------
package org.apache.jetspeed.modules.actions;
import org.apache.jetspeed.portal.portlets.VelocityPortlet;
import org.apache.jetspeed.modules.actions.portlets.VelocityPortletAction;
// Turbine stuff
import org.apache.turbine.util.Log;
import org.apache.turbine.util.RunData;
// Velocity Stuff
import org.apache.velocity.context.Context;
public class SimpleVelPortletAction extends VelocityPortletAction
{
public void SimpleVelPortletAction() {
Log log = new Log();
}
public void doList(RunData data, Context context)
{
Log.debug("SimpleVelPortlet ->Lista");
context.put("message", "List required...");
}
public void doDelete(RunData data, Context context)
{
Log.debug("SimpleVelPortlet ->cancellazione");
String passedId = data.getParameters().getString("passedId");
context.put("message", "Deletion required for object with id:" +
passedId);
}
public void doAdd(RunData data, Context context)
{
Log.debug("SimpleVelPortlet ->aggiunta");
String passedTitle = data.getParameters().getString("passedTitle");
context.put("message", "New user required with title:" +
passedTitle);
}
public void doUpdate(RunData data, Context context)
{
Log.debug("SimpleVelPortlet -> update");
String passedId = data.getParameters().getString("passedId");
context.put("message", "Update required for object with id:" +
passedId);
}
protected void buildNormalContext( VelocityPortlet portlet,
Context context,
RunData rundata )
{
Log.debug("SimpleVelPortlet -> Normal Context");
}
public void doPerform(RunData data, Context context)
{
Log.debug("SimpleVelPortlet ->do Perform");
}
}
