fs->aw, nn: I'm lost in the drawing/spreadsheet object hierarchy here ...
When a sheet is removed via UNO API, then ScDrawLayer::ScRemovePage broadcasts
aScTabDeletedHint. This is observed by ScDrawView::SFX_NOTIFY, which then does a
HideSdrPage. Unfortunately, this means that now the drawing layer is somehow
corrupt, which can be observed by hovering with the mouse over the active sheet
- this asserts, since now the ScDrawView does not have a valid SdrPageView
anymore - it was deleted and reset in HideSdrPage.
Hmm. Comparing this where a sheet is deleted manually, there is *also* a
HideSdrPage called, which also resets the SdrPageView member to NULL.
However, in this scenario, there's an additional ShowSdrPage called, which
re-creates it, with the following stack:
SdrPaintView::ShowSdrPage()
FmFormView::ShowSdrPage()
ScTabView::TabChanged()
ScTabView::SetTabNo()
ScViewFunc::DeleteTables()
fs->nn: Is it possible that removing sheets by API is missing some restoration
of the current sheet, or something like this?
