But can't you just call another mehtod which peruse ageRange and produces a
boolean, like;
<option jwcid="@Option"
selected="ognl:eventRegistrationUpdate.checkIt">
And in the class;
public boolean getCheckIt()
{
boolean rv = false;
Object o = getAgeRange();
...
... check o (or whatever it is) an determine if you should return true or
false
...
return rv;
}
Cheers,
