[news.eclipse.birt] Re: As per data availability display table or hide

Take a look at this example. Look at the scripts on the dataset and the visibility expression on the table.

Hi All,

I am using BIRT2.2.1. I've created rptdesign using xml file as my data Source, with multiple datasets. Now my problem is when i ran a report i am not getting output because some datasets doesn't have data in the xml file. I requested you all how to hide visibility which dataSet doesn't have data.


Please suggest me.

Thanks.
JP
