Could you elaborate more on this error which you are getting to advise further.
Report rendering first time only on the page, it's not rendering the subsequently(every time ).
Ex: 1. If Search with Name all name will display in the report, [this is first time]
2. if search with name and pincode number (just change the input parameters and trying to render the report]
result is not showing the jsspersoft report.
I am suspecting the post back events issue.
