sometimes the PDM switches the data that is available in a drop down (i.e. select a zone cell and i get a list of phases)
when the error occurs and i click the refresh button in the pdm i get this dialog:
dTools pdm error.JPG
seems to be pretty consistent: bug occurs, click refresh, dialog shows.
hope this helps get some of the bugginess out of pdm
bump:
another product grid error
