Maybe you used crosstab in your report. Make sure every field is in a proper position.
If the file in JRXML format, open it in an editor and remove the below code and try to open it again.

Please backup your previous file also.

<crosstab>

Some code here also

</crosstab>

Sorry, I do not understand.

The situation is:

I was using iReport 5.6 and migrated to jasperStudio 6.16, after which this error occurred[/code]

mahadiosb · May 5, 2021

Yes in that case some XML code tag not supported in the upgrade version. for that, you have to remove the <crostab> tag.

you can add code here for better understand
