Remaining boundingbox in imagery preferences outline preview after adding a new shape and updating the imagery preferences

[mdk]

What steps will reproduce the problem?

1. Open Imagery Preferences
2. Select an imagery provider which has <bounds> without <shape> (see ​http://josm.openstreetmap.de/wiki/Maps and sub-pages for different countries) -> you see the bounding box in the preview map of the preference dialog
3. Edit the wiki-page and replace the <bounds> element with a new (and valid) which contains a <shape>.
4. Refresh the imagery preferences ("reload defaults" button right of the preview map)

What is the expected result?

After reloading (or at least after re-selecting the chosen imagery provider the preview should change from the old boundary box to the new shape.

What happens instead?

The old bounding box is nw shown always, until you close and re-openthe preference windows. If you select any other imagery provider, the outline for this provider (shape, bounding box or nothing) is shown PLUS the old bounding box from the changed imagery provider.

The list of shapes shown in the preview map must be cleared after reload. And it would be nice, if the preview is refreshed after "reload defaults".

Please provide any additional information below. Attach a screenshot if possible.

You can easily create a shape with the imagery-xml-bounds plugin (​http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Imagery-XML-Bounds):

• open new (empty) layer
• show the imagery layer
• trace the outline of the imagery
• select the outline and call "XML imagery bounds" from the context menu of the selection view
• copy <bounds> element with <shape> child element
• add or replace <bounds> element in the ​http://josm.openstreetmap.de/wiki/Maps wiki-page

valid bounds for "SIGIP - Orthophoto 2012" from CH

[mdk]

I add (see attachment) a valid <bounds> element for the Swiss (CH) "SIGIP - Orthophoto 2012" imagery provider.

You can finally add this shape, because it is actual missing and it is valid for this provider!

[mdk]

Perhaps I can point directly to the problem: I saw, that you can make multi-selection of imagery providers. Each time you add a provider to the selection, the outline (bounding box or shape) is added. Each time a provider is deselected, the outline is removed from the collection to be drawn in the preview map.

But it looks like on "reload defaults" the selection is cleared without removing the outlines from the previous selected providers.

So either ANY change of the selection-List must also change the list of outlines to be shown, or don't have two independent collections (selected providers and outlines to display) and create the list of outlines each time the selection changes directly from the list of selected imagery providers.
