[swathi13]

Hi,

Please provide me the solutions for the following queries.

1. I am upgrading my IReport from 4.1.3 to 4.7.0

after that when i change in the report and saves it it is generating some uuid code.

please tell me how can i avoid that?

2.How to change headers dynamically?

currently i have added printwhenexpression with condition.But its not working for me.

3.other report formats are working properly but my csv file is generating extra commas.

here i am attaching the my JRXML file.

Thanks in advance
