I've created a grid in the Rally app builder. The grid has fields from the defect model and also some fields that are only defined in my data store but not in the defect model. I want to use the fields to capture defect scoring values and then update a custom field we have created in the defect model. I can do the calculations but when I update the field in the grid, the value doesn't show unless I tab into that field. Also, I cannot get the data store commit to actually update the defect with the new values. Not sure what I'm doing wrong. Any ideas?
