I have a Web Prompt with constraints that can be changed with a Web Combo. The Model Dialog has a Web Property that stores the combo selection that is defaulted to one of the combo items. The PromptList works fine if the default property displays constrained records when it is first "Loaded". However, if the default setting in the property generates no matching records when the prompt is "Loaded", the prompt will not display any changes from the combo later! In the "Onchange" the Web property is set, RebuildAllContraints is sent to the DD and MoveToFirstRow is sent to the PromptList. Any suggestions/ideas?
