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

public String desiredComponent;

public WOComponent doWebTemplate()

String desiredComponent = pagesDisplayGroup.selectedObject ().pageTemplate();
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?
