Some other things you can use:
${myActionProperty.subProperty!}
Prints nothing if subProperty doesn't exist or is null
${myActionProperty.subProperty?default("default value")
Prints "default value" if subProperty doesn't exist or is null
The first expression (ending with !) is most similar in behavior to
the <@s.property /> tag.

I'm a newbie trying learn how to use FreeMarker for Struts result
pages.
This code works: <@s.property value="myActionProperty.subProperty" />
This code triggers a FreeMarker error (expression undefined):
${myActionProperty.subProperty}
Obviously, I'm missing something very simple. But what is it?
Is there any way to dump the tree of EL variables so that I can
undertand
better?
Is there any good documentation on using FreeMarker in Struts? I
can find
great documentation on FreeMarker by itself and Struts by itself,
but I
can't find any docs or tutorials on using the two together. Any
suggestions?
