Hello,
My mission;
I want to implement a help window based on all help that is related to a page.
This means I want to trigger the portlets to add help to a specific area on the
screen. In my case it will be a div that is hidden until the user presses on
the help button.
This way I have a help that is generated by a portlet based on all portlets
that are on the page.
My problem;
To accomplish this I'm using the actionURL that is standard for every portlet.
So I have one help portlet that generates the needed help for all portlets
using the actionURL.
However this is failing; my piece of code;
//for every window on this page we will try to trigger the help page and
include this information in a global help page
for (Iterator windowIterator = currentPage.getChildren().iterator();
windowIterator.hasNext();) {
PortalNode portalNode = (PortalNode) windowIterator.next();
if ( portalNode.getType() == PortalNode.TYPE_WINDOW ) {
String actionURL = getPortalNodeHelpURL( resp, portalNode );
private String getPortalNodeHelpURL(RenderResponse resp, PortalNode portalNode
){
if(resp instanceof JBossRenderResponse){
try {
PortalNodeURL childURL = ((JBossRenderResponse)
resp).createActionURL(portalNode);
childURL.setParameter( "mode", "help" );
return childURL.toString();
This call leads to an exception.
Can someone tell me what I'm doing wrong?
Jeroen.
