[Helma-user] Bug with getOrderedView ?

[Hannes Wallnoefer]

Hi Jonathan,

thanks for the report. Unfortunately, floats and integer sometimes get
mixed up in Rhino/Helma for various reasons. I just committed a patch
to Helma CVS (both HEAD and helma_1_5) that should fix the problem.
Let me know if you need help building from CVS, alternatively you can
wait for new snapshows to appear at
