in GFX/VML the shape of a path that has been removed then added back to the surface can't be updated

[cjolif]

After removing & adding back a path to the surface if you call setShape() on it with a new shape, the path won't be correctly updated if you are running on GFX/VML.

This is working well with GFX/SVG.

See attached example (runnable from dojox/gfx/tests).

This is hurting charting when enableCache is on markers of the line chart.

I'm not sure at all why but it seems to come from the fact that after removing the v:shape and adding it back the "path" of shape is not anymore an element but an attribute! Which means that when in setShape we try to do this.rawNode.path.v = newpath this does nothing (as path here is the attribute not the sub-element). Changing the code to this.rawNode.path = newpath makes it work.

Given that VML is only needed for IE8 support, and is not likely to matter much longer, we have no plans to fix this. We will consider a pull request if someone wants to fix this.
