Description a.dwehus CLA 2011-01-04 06:59:57 EST 
Build Identifier: 20100617-1415

We are using Citrix to access our application, therefore the memory for each user is limited (on the test system to 256MB). This seems to lead to an outOfMemoryError when generating Word Documents, if the result set gets to big (in our case about 460 pages with 8724 result rows). When generating a pdf with the same report and results it is working fine.

This is what courses the error:

Reproducible: Always

Steps to Reproduce:
1.Create a simple report with a simple output table.
2.View report as doc (make sure the maximum number if data rows is not limited as it is by default in the report designer) with very large number of results.

Were you using the ALL-In-One or genReport to render the report?
Comment 2 Xiaoying Gu CLA 2011-03-07 04:08:16 EST 
I can not reproduce this issue in the rcp designer with the 2.6.0 release. 
The -Xmx had been set to 256M to simulate your memory setting.

The doc file was exported correctly. Please see my attachment which was using the sample database.
