[mapguide-users] hide layer on box checked

[dorra2007]

I used this function to get the session ID :
document.myform.session.value=parent.parent.mapFrame.GetSessionId();

But I have this error:

The session ID is invalid because the session separator character was not
found

Have you an idea about the "session separator"?


Regards.
