Wt

Hi,

WMenu with submenu and with setInternalPathEnabled suffers with multiple emitting of signal itemSelected, when an item in the submenu is selected.

It is caused because of internal path handling.

Imagine this simple two-level menu

+ ItemA
|-- ItemA1
|-- ItemA2

When ItemA1 is selected, then itemSelected signal is emited from subMenu (1). Then internal path is changed (2) and itemSelected signals for menu (3) and submenu (4) respectively are emited.

[2012-Nov-08 14:34:13.921730] 2597 [/ runm4qpxQSqeyVpW] [test] "/itema/itema1"      // (2)

That is inefficient. Consider some computation and updating of contents for each call of my handler of itemSelected signal. Tho log should contain just lines 1 a 2 (maybe 2 and 4 would be fine too).

The log is from example from attached file.

Tested with wt 3.2.3.
