Mappaint style for osm object not updated when tags change

[bastiK]

Drawing style is not updated when removing tags:

• draw way
• presets > relations > boundary
  • select "Boundary type: administrative" and "Administrative level: 1"; Ok

-> Way is drawn as dashed line

• select relation
• in tag dialog:
  • remove tag type=boundary
  • remove tag boundary=administrative
  • remove tag admin_level=1

(order is important)

-> dashed line is still drawn

The type=boundary tag makes it a multipolygon, so this could be related to the multipolygon cache.

There is the same problem with all relation types.
How to reproduce:
use the following mapcss mappaint style

relation > way
{
	color: parent_tag("colour");
	width: 8;
}

create a way
create a relation with the way as member
give the relation the tag colour=green

then you can change the colour of the way by changing the value of the key 'colour' of the relation to yellow, red,...

If you use the edit relation window to change the colour then it works fine and the colour of the way updates.
If you select the relation and change the colour directly in the dialog panel on the right, then the colour of the way does not update. Then you need to modify the way e.g. add a node (just moving existing nodes or the whole way does not update the colour) or switch the mappaint style off and on again.

I tested with josm-stable (6891) and josm-latest (6909).

@bastiK: did you start to work on this one?

[bastiK]

no, feel free to assign to yourself...

I won't have enough time this month

There is the same problem even without relations but with child selector.
How to reproduce:
Use the following mapcss mappaint style

way["addr:housenumber"] > node
{
	symbol-shape: circle;
	symbol-size: 20;
}

draw a bulding (e.g. with building tool)
add to the building the tag addr:housenumber=5

The mappaint does not update. Sometimes it does update 2 of the four nodes of the building when you move one node.

Tested with JOSM stable 7000 and latest 7080.
I hope this helps to track down the problem.

Thanks for the fix.
