NodePage - DetailForm - Veto Form desactivation [message #1782278]

HI
I have a NodePage with a Detail form. On the detail form I can enter data.
To store the data (and keep the form open), I've added the StoreButton to the form and removed the OKButton.
i face the problem, that the user can leave the detailform and activate another node in the same outline or veen change the outline even if ther eis some unsaved data on the form.
Is there a possibility to keep the user on the form, if the form is dirty? something like throwing a vetoexception in a formtobedesactived trigger?

TIA
rene

Hello René

I don't think that there is a easy built-in option to do this.

The closest thing I could think of would be setting the IPageChangeStrategy on the outline (override createPageChangeStrategy, or call the setter) and modify it to check that if there is a DetailForm, it has been saved (and then not switch the form at all).
However, I can't tell you if that would lead to a consistent behaviour with the tree of the outline, which possibly already updated with the user's selection.
