I am using pagesDisplayGroup.selectedObject() successfully in
other actions of the page.
Also, on the page I have a WOtextField with value =
pagesDisplayGroup.selectedObject.pageTemplate
that shows the data which I am trying to use. So selectedObject()
is not null and the attribute "pageTemplate" has some data in it.
I can display the field on the page, but how do I call the same
data in an action?
String desiredComponent = pagesDisplayGroup.selectedObject
().pageTemplate(); doesn't seem to work.
Thanks again.

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?
