DrawAction: Wrong start point for helper line after adding node with double click

Reported by: Habakuk Tibatong Owned by: team
Priority: major Milestone:
Component: Core Version: latest
Keywords: Cc: xeen

Description

When I add a single node with a double-click it is selected after that. When I add a second node both are selected, but when I add a third node only that one is selected, another new node and the third and fourth are selected, the fifth node again is the only selected ...

Does it have a reason or is it a bug?

It's a defect. Double clicking behaves strange drawing nodes at strange positions as well as drawing lines sometimes or not and drawing single nodes after lines have been displayed. Someone broke the drawing code I would think.

Though there is mostly minor damage this bug can mess up nodes when the user doesn't recognize that two nodes are selected. Problematic, for example, when editing house numbers: copy node with address infos, insert node (Ctrl+V) and edit house number - you'll see that original and new node are changed. I've no evidence but I believe that not all users notice their mistake and upload.

r2528 is a quick fix for the specific issue described in this defect. The code in DrawAction should be brushed up, though. It still behaves weird in some situation, for instance

  • add a node with double click -> node n1 is added
  • single click somewhere (but not on a way) -> node n2 added
  • observed: JOSM paints a helper line from n1; expected: JOSM should paint a helper line starting from n2

Leaving this ticket open, but lowering its criticality.

r2528 seems to have introduced a new problem:
To reproduce, open any area and begin editing.

-Begin drawing a Way
-Move mouse to 2nd node. Take care not to move the mouse during:

Click to add 2nd node to way
Double click on same node without moving mouse results in exception below
