Print when expression problem

[marianela]

Hi everyone¡¡

 

Sorry to bother you with this (apparently silly) problem, but I hope some body can help me...

I have a report that has a group and in the detail band has a subreport. What I want at first (and already achieve) is to return the REPORT_COUNT from the subreport to master report.

Now that I have that variable in my master report, I want to use it in an expresion that let me not print the groupheader if there is no data return by the subreport.

I think that maybe this expreesion should work:

Code:

( $V{SubrptCount}.intValue()==0 ? Boolean.FALSE : Boolean.TRUE )

But I was wrong.. :(

Then I think that could be something like...

Code:

[code]new java.lang.Boolean($V{SubrptCount}.intValue()!=0)

But this didn't work either..

I don't understand what is the problem, but when I use any of those espression it oly works with some records..It's like some numbers (167,133,etc) are taking like 0 and some 0 are taking like others...:blink:

I know this sound a little confuse...but this is my problem...

Pleaseee I really need help..Anything will be appreciate

I don't know if i understand your problem correctly but have you tried the following expression?

 

Code:

new Boolean(!$V{SubrptCount}.intValue() == 0)

instead of

new Boolean(!$V{SubrptCount}.intValue() == 0)

 

use

new Boolean($V{SubrptCount}.intValue() != 0)

Hi aniruddh4u,

Thanks a lot for your awswer, but I'm still having my problem...

Could it be that your SubrptCount Variable is of type string and not int?

 

If you want to look if youre sting variable is NOT empty then use:

Code:

new Boolean(!$F{SubrptCount}.equals(""«»))
