X-Git-Tag: fop-0_93~226
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=f970e15d282ae09cd0a00f04745d237e3fa71ac4;p=xmlgraphics-fop.git

Bugzilla #39533:
Bugfix: NullPointerException in RTF output when a table does not contain table-columns.
The code now informs the user that he should explicitely define the table-columns.

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@407576 13f79535-47bb-0310-9956-ffa450edef68
