[Openroad-users] Tabpages

[Bodo Bergmann]

Right.
The TabFolder (field1 in my example) is a top level field,
so I did DeclareData() on it.

I didn't know that the pages have to be created on user request
(where data has already been enteredd in the static pages),
my example works when they are created in the initialize block.

You could also use it later, but then you would have to save the
current data/objects for the existing tabpages before using
DeclareData()
(after UndeclareData() if required) and reassign this data afterwards.

Isn't the problem that declare data only works on top level fields?  The

tab page is a child of the tab folder, so unless the tab folder is 
nameless the .DeclareData() route cannot work, unless I am mistaken.
