But the trouble starts when I change the action to this...

WOComponent nextPage = pageWithName( desiredComponent );
return nextPage;
}
What is the correct way to write the line to get the value of
"pageTemplate"?
I get a can't resolve symbol error, or with other variations on the
line I'll get a Null pointer exception when it runs.
I guess that selectedObject is null. How does the page know, what the
selectedObject should be? How do you set this?
Next guess: you may display a page with a list of objects, where each
of them has a "pageTemplate", somehow you select one of the objects
and it should return the string value - but you have to assign
"selectedObjects" of the displayGroup somehow.
Can you give some more info?
