Show/Hide column functionality shows generic names instead of actual ones

Issue:

[toc on_off::hide=1]

The Customer is trying to use the show/hide columns functionality of jasper report table component. When they try to show hidden columns, it is showing the column number instead of column name.

Here's the screenshot of the issue: 

Below is the snippet from the jrxml file for a report which produces this error. 

Resolution:

So, the issue here is that the columns are called Column_x because the column headers are empty. Normally, the column name is the text in the column header but if the header is empty, these generated names are used. 

Unfortunately, there is no way you can use table group headers names instead of table column headers. The current JIVE implementation for report interactivity allows only to work with column headers. However, we have an enhancement request to implement JIVE feature on Table Group Header with internal ID JS-55803.
