[Plone-developers] mTool getGroups() vs groups tool getGroupMembers()

[agnes <ag...@th...>]

I have a wierd and very annoying issue.

On my plone2 site, at the registration, a user can specify a group he'll be
part of. To effectively make this new user become a member of the group he
specified, i'm using the addGroup() tool after the user is being created (in
the register py script). Then, once he is logged in, I checked whether or
not this member is part of a group to diplay him special information. To do
that I use the membership tool getGroups... And nothing comes out: it looks
like this user is not part of the group ! Though if I look for this member
in the Plone configure interface, in the specific group page, he is in
there...
The difference ? in one screen i use the membershiptool getGroups , in the
other screen the groups tool getGroupMembers() is used... ??.
I also noticed that after i checked for the member in the plone interface,
the getGroups() starts to work and my user finally get the proper info... It
looks like something needs to happen to have the membership info propagated?
How can i get that simple thing right ...?
Can someone help?

Thanks you

Agnes
