[Zope] question on setting PropertySheet value from External Method -- solved

[Tim Lynch]

Got it.

I had poured over the list archives without finding the magic incantation before
posting my plea to the list. Finally, this afternoon while poking around Zope Labs
I came across a recipe that got me to:

 self.resources[recordID].propertysheets.Basic.manage_changeProperties({'Title':t})

which works.

Much thanks to 'peterbe' and his/her message of 2001-08-08.
