RE: What is wrong with my with OGNL Map expression??
Hi Griffith,
Assuming there's an attribute with name 'mySessionAttribute' in the
Session scope
and you can access the same in you jsp as below:
s:property value=%{#session.mySessionAttribute} /
May be this will help.
Thank you.

Subject: What is wrong with my with OGNL Map expression??
Hello all,
It seems as if I am always at odds with trying to figure out the correct
OGNL syntax. I have a MapString,String in the HttpSession, and I'm
trying to use one of the values in the map as an anchor tag in a link.
The map is stored in the session as an attribute named
genieProperties...
None of these expressions work...
s:url id=myLink anchor=#session.['genieProperties'].url /
s:url id=myLink anchor=#session.genieProperties['url'] /
s:url id=myLink anchor=#session.['genieProperties['url']'] /
s:url id=myLink anchor=#session.['genieProperties.url'] /
Am I at least close? Any assistance would be appreciated.
Best Regards,
MG

It could be a conflict with JUEL which uses #, try the other
notation (I think you can disable JUEL somewhere):
#...@java.util.linkedhashmap@{ foo : foo value, bar : bar value }

Actually the name is Unified Expression Language, JUEL is just an
implementation of it.

The %{} are often left out by people, but they're critical. That's what
says this is an OGNL expression. Musachy's response illustrates the
potential confusion as to what EL you're using when it's not specified.

RE: What is wrong with my with OGNL Map expression??
Assuming the attribute in the session scope is a map, how would I get
the value for the map entry called url?
Would it be something like this:
s:property value=%{#session.mySessionAttribute['url']} /

RE: What is wrong with my with OGNL Map expression??
Ding! Sorry I didn't see this reply earlier when I repeated how do I get
the map value. Again, thanks Dave! Is there such a thing as an OGNL
expression validator? It would be nice to be able to fool around with
the expression interactively until I am able to get to the correct
expression.
Cheers~

Re: What is wrong with my with OGNL Map expression??
if you have the debugging interceptor applied to your action, you can
add debug=console to the url, and you will get a console where you can
type OGNL expressions, and see the result.

Re: What is wrong with my with OGNL Map expression??
Just to reiterate what Dale said, we¹ve taken to using the %{} across the
board as we were having problems with conflicts. In my experience this has
slowed my hair loss significantly.
