Can a textField in subreport with “Stretch with overflow” span across multiple pages?

I have a subreport with just one text field. This text field can have somewhere around 5000 characters retrieved from a service.

My goal is to show this subreport on the parent report. It should start from the "Float" position where I place it to multiple pages in a continuous manner.

When I have this subreport in my parent report, the text clips when the "Stretch with overflow" of the text field in subreport is set to false. When I set "Stretch with overflow" to true, the text field appears blank on the pages but takes up the required space on the parent report.

I have tried the following but nothing seem to work:

1. In the sub report:

  • Print when detail overflow = true
  • Split Type = "Stretch"
  • Ignore pagination = true

2. Main report:

  • Split Type = "Stretch"
  • Print when detail overflow = true on subreport object
  • Print in first whole band = true

Trying it since few days has made me feel that it is impossible to have a overflowing text field across pages.

Please let me know if its even possible to have a subreport with text field to span across multiple pages.

Compile the subreport, set correct path to subreport and test you self.

Note: I'm not setting a lot of attributes on the reportElements.
