"printWhenExpression" does not work.

[ATrica]

In the following code, the "printWhenExpression" does not work.

The parameter W_Transe value = "YES".

No detail row printed.

PLEASE help me.

Many thanks for any usable idea.

what are you trying to do exactly ?

I believe I am having the same issue.  In my case, I want  a group band to print based on the value of a user parameter.  I entered " $P{SUMM_TYPE} == "Detail"" for the 'Print When Expression', but the band does not print at all, even when the condition is met. It only prints if I remove the value from the 'Print When Expression.'

Hi !

Exactly as in your report. The component having "printWhenExpression" is not printer, even the condition is TRUE or FALSE. In my case it is a DETAIL row.

No idea about this non functioning clause ?

I solved it  ! ! !

<printWhenExpression><![CDATA[$P{W_Transe}.equals("YES")]]></printWhenExpression>

Many thanks !
