are actually removed.

Key: PIVOT-766
URL: https://issues.apache.org/jira/browse/PIVOT-766
Project: Pivot
Issue Type: Bug
Components: wtk
Affects Versions: 2.0
Environment: n/a
Reporter: Chris Bartlett
Assignee: Chris Bartlett
Priority: Minor
Fix For: 2.1
Many WTK implementations of org.apache.pivot.collections.Sequence fire
xxxRemoved() events, even if no items are actually removed.
The events will include an empty list of items that were 'removed', but it
would be preferable to simply suppress the event.
All other WTK Sequence implementations that I checked already suppress such
non-events.
Fixes required for the following classes
org.apache.pivot.wtk.Accordion.PanelSequence
org.apache.pivot.wtk.Form.Section
org.apache.pivot.wtk.Form.SectionSequence
org.apache.pivot.wtk.GridPane.Row
org.apache.pivot.wtk.GridPane.RowSequence
org.apache.pivot.wtk.Menu.Section
org.apache.pivot.wtk.Menu.SectionSequence
org.apache.pivot.wtk.MenuBar.ItemSequence
org.apache.pivot.wtk.TabPane.TabSequence
org.apache.pivot.wtk.Window.ActionMappingSequence
org.apache.pivot.wtk.Window.IconImageSequence
