Multiple Datasources

[mat.murdock]

When I have multiple data sources I get the following error. If I remove all but one then my report runs fine. It runs fine in the AIR client and in .Net, but not when rendering locally using Java.

Thanks,

Mat

Hello.

We can't reproduce this bug. We made several tests with several data sources but no error occurred.
It seems that other process modify datasource collections during rendering.

When I have multiple data sources I get the following error. If I remove all but one then my report runs fine. It runs fine in the AIR client and in .Net, but not when rendering locally using Java.

Thanks,

Mat

Ok, I have narrowed the problem down to having variables in the SQL string. If you create 2 datasources with a string similar to this:

"select '{varSomething}' as something from dual"

Then you get the error. If you only have one query with a variable in it then it works fine.

Thanks,

Mat
