Sorry for the inconvenience.
This became weird to me. On my test machines, I never reproduce the problem in LV2012 and even in LV2011. The code behind the PropertyDialog is setting a tab control value (showing the sub panel) by a tree control value change. In LV2011, the tab control value is set by local variable. Local variable sometimes ignores updating the front panel data in certain context (for performance), which could result in the bug mentioned in this thread. In LV2012, the tab control value is set by its own terminal instead. This, in principle, should update the front panel data. But somehow, it is not in some cases.
So I would need your help who can reproduce the problem.
1) Do you use localized LV or English? Is the VI has the Plot in a project or not? When opening the PropertyDialog, is the page not changeable at the very beginning?
2) Will it help if changing the terminal to a property node "value" in the "Page List" value change event in the "vi.lib\Math Plots\3D Math Plots\3D Surface\3D Surface\Public\Property Page\Property Dialog.vi"? After changing, please try PropertyDialog in the Surface Plot.
Thanks,
