Set IsSummery to false

Hi there! I have a problem with the limitation of Lotus Notes. I have a lot of fields on a form, and now the 32k of the view column are reached. The problem was described here: http://www-01.ibm.com/support/docview.wss?rs=899&uid=swg21087474

The most of the many fields I have, are not needed in Views. So I try to change the IsSummery property to false. When I run this agent, and save the document the flags are setted to false. But when I save the document (in UI), the flags are resetted to true, so I become the error message.

I can’t use a RichText field, because the values of the many fiels are all calculated (computed fields).

Any suggestions?
