I now have a glimmer of hope for escaping the drudge shop with Dojo and Java to do an app which really deserves Python. I fear I am new enough to pyjs that I am a bit confused on setting the property. I see setElementProperty and tree_item_foo.setElementProperty(whatever I try) throws errors. I also notice Props and weirdProps and I used my grabit tool to do a spreadsheet on where they occurred. About 30 files seem to have that. Is there something else I should be looking for before I reserve the weekend for reading code? best regards, Michael --
