Hi, I realize this is not a Documentum support group, but I know others out there are using it and I thought I'd toss out an issue we think just isolated as a heads-up but also to see if anyone else has run across it.
It appears that once Webtop's Virtual Document Manager (VDM) builds a virtual document from its components, it maintains a "death-grip" on the descendants *at the time it is instantiated" and never lets go for the duration of that Internet Explorer session. (Caveat: We are currently using some flavor of IE6 on Windows XP. Our Documentum version is 6.5 and some SP ... I forget which, exactly. Whether this behavior is replicable using other versions or not, I do not know.)
This is bad because if you instantiate the root of a document within VDM and subsequently you, or someone else, updates chapters or subsections, those changes are NOT reflected in VDM or even in exports from VDM. (We are currently testing what happens to checkouts in this scenario.)
Regardless, we will be turning this over to our Documentum team to replicate and in turn discuss with EMC/Documentum Support. I'll let you know if we get confirmation of this behavior (whether a bug or a "feature").
