Forum OpenACS Development: Re: General Comment editing issue Solved, and the true source is in core.

Actually unclobber only works if the variable was previously set. If it was not set before the multirow it will not be cleaned up after the multirow so you end up with new variables.

This makes it tricky with using template::list since naturally you want the filter names to match the varaible the filter is filtering for, and if the filter is not set, it will be set at the end of the multirow causing the filter to be applied incorrectly.
