SOLVED
i thought i have to write my own validator, looking into IS_IN_SET i
stumbeled upon the following code in the first few lines
if isinstance(theset, dict):
self.labels = theset.values()
hmmm, lets try
folders = dict(folders)
db_webfolder.parent.requires = IS_IN_SET(folders)
form_file = SQLFORM(db_webfolder)
and it works!!!
maybe this should be documented somewhere, e.g. in the docstring of
IS_IN_SET! would make it at least a bit easier to find out
