Hello,
I'm am a bit confused about the correct usage of variables and their scopes.
I defined a variable V_REP_VAR as "Report Variable" in the outline on
designer with a default-value of '<default>'.
When I use this variable in javascript expression builder it is
automatically inserted as "vars['V_REP_VAR']" which correctly gives me
the default-value.
But using the reportContext-methods does not deliver the value.
Is there a connection between the 'vars[..]'-Array and the
reportContext-methods 'getGlobalVariable(..)' and
'getGlobalPersistentVariable(..)' ?
I have some EventHandlers in Java in my report, that need this variable,
but cannot access 'vars[..]' obviously.
Here's my sample :

Hi Jason,
that worked, Thanks!
I didn't think of trying 'getPageVariable'...was looking for something
more 'global'.
