#216 RunTime error in ParsedExpr.py

[mattnoble]

I am using 4suite under mod_python and when I try to use Ft.Xml.XUpdate.ApplyXUpdate() I get a runtime error "RuntimeError: function attributes not accessible in restricted mode".

I've tried to do a reload of Ft.Xml.XUpdate just before calling ApplyXUpdate() but this does not help.

I have seen one reference to this issue on another website (http://lists.fourthought.com/pipermail/4suite/2007-September/008342.html). That did have a possible workaround with a probable memory leak that I can't justify using on a production server. There were no other comments to that item.

Anyone got any ideas on how this can be fixed?

The tail end of the traceback (that includes all 4suite functions) is as follows:
