[Zope] Passing query strings in trees

[Jim Cain]

All,

I have a Zope tree structure that requires a query variable to be passed to
it. The first time through, I can pass it on the http request with no
problem:

http://www.mgmt-inc.com/some_object?variable=value

But this query string is not included in the [+] and [-] links to
expand/contract the tree so that I can pass it on to the next rendering of
this object. How do I do this?

Thanks for the help,
Jim
