Is it possible for you to share your workspace name and give DEMO the rights to modify the app? I looked at your app, but without seeing what is going on behind it, it is hard to give you any advice.
Workspace Kirspel, DEMO now is a developer.
Can i have developer User in your Workspace i promise Dont Change Any Thing In you Workspace
I checked using firebug. If i type something and clicked ok button in pop-up window means It (the value) should populate into the hidden item(f10) in your case. but the hidden item is not getting populated. I am not able to login into your workspace as a developer. Can plz check, how you are populating the value from pop-up text field to hidden item?..
If the value populated in hidden item then definitely it will store in database column.
Also i checked in Dan McGhan's example for this using firebug. There the value is populated to hidden item. I think you missed something for populating the hidden item. Plz check.
If you can share your workspace details as a developer.
My timing is terrible. I hadn't had a response on this so Saturday night I turned off developer access for my DEMO account.
I've now reset it to developer. Workspace KIRSPEL. Username DEMO. Password DEMO.
