ReportScripting in BIRT 2.2.1 : Problem with the evaluation of an Expression [message #490610]

Hi,

I'm developping reports in BIRT 2.2.1 and i'm using some scripts to customize it. I would like to know how can I do to evaluate a NamedExpression on a Data item.
I know in BIRT 2.3, we can do this with : reportContext.evaluate(this.getNamedExpression("myNamedExpression ")).
But I'm not allowed to upgrade my BIRT for 2.3 version, so how can I evaluate a named expression in BIRT 2.2.1 because the evaluate() method does not exist in that version?

Thanks by advance,

Maghen

Maghen,

Can you try just eval(this.getNamedExpression("myNamedExpression "));

I do not remember if this works in 2.2 but worth a try.
