Conditional text when no data found...

[milito]

Hi:

 

I want to put a conditional text when no data found, somebody can help me?

By definition you won't be able to put such a field in the Detail Section because it won't exist if there's no data.

 

 

To determine that there's no data you inspect the inbuilt variable REPORT_COUNT. If it is zero then the report is empty. Unfortunately the value isn't available until the report is filled, and that means you can't put it in a header or title section either.

 

 

First you need to set the Report Property setting whenNoDataType to "AllSectionsNoDetail"

 

 

Now you need to set up a text field in any FOOTER or SUMMARY section, with a printWhenExpression setting of "new java.lang.Boolean($V{REPORT_COUNT}.intValue()==0)".

 

 

If you put this field in a footer section then the text is going to appear at the bottom of the page.

 

 

The summary section is a better place to put it, as it will appear right underneath your report title and page header.
