| I switched over to Xcode 2.2, which is working pretty well for me, but I have run into trouble editing fetch specifications. Specifically, I want to be able to test one of my attributes in an entity to see if it is null. If I use the qualifier editor in Xcode, and try to say letterDate != null, it ends up as a letterDate != "null", which throws an eror at run time as it tries to compare this datetime column to a string. I thought I would try letterDate > 0000-00-00 but again, this is treated as a string. Would setting a valueType for this attribute (not sure to what) allow me to do date comparisons? Or do I have to use a dictionary binding?
