Nodes that are not selectable are posible select via selection history

[alv]

The title may seem cryptic, but steps to reproduce:

• draw a unclosed way with four nodes
• select each node
• distribute nodes
• select one of the middle nodes
• delete that node
• using the select history on the right hand selection panel, select the first line that reads "4 nodes"
• you see three remaining (as in not deleted) nodes selected
• select distribute nodes

expected result:

• equal distances between the three nodes

result:

• no change, equal distance between all four nodes, including the deleted.

In fact, all (or many) tool actions work with the deleted nodes as if they still existed, when reselected in this manner. At least align in line, align in circle, orthogonalize (ways + two deleted nodes).

Deleted nodes should not be selected. Patch make sure that only selectable item are selected. It also fix name calculation to selection history menu.

This patch is wrong. JOSM handles deleted, incomplete and other non-real data. This is perfectly valid. The tools need be fixed not to use this data when doing their job.

I agree, but most of the editing tools cannot handle deleted objects. Maybe we should add a parameter

getSelected(boolean includeDeleted)

and

getSelected() { return getSelected(false); }

Why not provide a method in the selection code for getting all data that is currently visible? That way the tools wouldn't all have to make the check by themselves.

I think that you are misunderstood patch. It not prevent handles deleted, incomplete and other non-real data. It only prevent select primitives that are not selectable.

There is not any error in distribute nodes as you can read original bug description. (User only don't see that deleted node)

What is purpose of PrimitiveId:isSelectable() function?

[stoecker]

Deleted elements are and should be selectable, like incomplete ones. If you can't select them, you can't work with them. Don't mix select by click with select by other means (like search).

[alv]

If the search should find deleted objects with their id, it doesn't. Tried with r4279 and r4620.
