svn commit: r487182 -
/jakarta/poi/trunk/src/scratchpad/src/org/apache/poi/hslf/usermodel/SlideShow.java
Author: nick
Date: Thu Dec 14 03:50:54 2006
New Revision: 487182
URL: http://svn.apache.org/viewvc?view=rev&rev=487182
Log:
Try to work with files that don't have a master SlideListWithText, but go straight into a Slides one. Throw a better exception on slides with a mixed first SlideListWithText (see bug 41176 for more details)
