Hi,
I just played around with this a bit, and if you set this.supportUse to false
in the initialize method, it will work.
I can confirm that rendering still works in my Firefox 3.6.13, Opera
10.62 and Google Chrome 8.0.552.224.
(Opera does not interpret Ctrl as intended, though: It seems to enlarge
the SVG-Elements, but it does so with supportUse as well and even if the
vector-features are plain circles This could be a separate ticket, I
guess. And I have no Opera 11 to test)
So in case you want to contribute a fix, and if this change doesn't break Opera
or other non-webkit browsers, I'd suggest removing the use-defs way of working
with graphicSymbols from Renderer.SVG entirely.
I'd gladly provide a patch if others don't disagree or step up first...
but I won't have time until monday. I'll leave a note in the files that
the usage of <use> was once implemented but lead to problems.
I currently cannot imagine a way to implement a specific test-case
showing the (soon-to-be) fixed bug. Can anyone point me the right direction?
Regards,
Marc

Hi list,
I've run into a strange issue present even in the trunk of OpenLayers:
If you have a vector-feature that is rendered with a graphicName (to have a rectangle or
triangle visualisation) and a select control working on the feature's layer, if you click
on the feature (selection control is active) and have Ctrl pressed on the keyboard, a new
browser window opens with an URL like
"http://openlayers.org/dev/examples/select-feature.html#OpenLayers.Layer.Vector_39-triangle";.
I see this behaviour in Firefox 3.6.13 on Ubuntu 10.10.
The vector-SVG is rendered like this:
<use id="OpenLayers.Geometry.Point_180" cx="173.80000305175895" cy="112.36666870117206" r="1" href="#OpenLayers.Layer.Vector_39-triangle" width="36" height="36" x="155.80000305175895"
y="94.36666870117206" fill="blue" fill-opacity="0.4" stroke="blue" stroke-opacity="1" stroke-width="1.6666666666666667" stroke-linecap="round" stroke-linejoin="round"
stroke-dasharray="none" pointer-events="visiblePainted" cursor="pointer"/>
and a symbol definition of
<defs id="OpenLayers.Layer.Vector_39_defs"><symbol id="OpenLayers.Layer.Vector_39-triangle" viewBox="-10 -10 30
30"><polygon points="0,10 10,10 5,0 0,10"/></symbol></defs>
You can experience the behaviour by visiting:
http://openlayers.org/dev/examples/select-feature.html
and running this inside Firebugs console, after rendering is done:
OpenLayers.Feature.Vector.style['default']['graphicName'] = "triangle";
Select the "draw a point" radio button, draw a point on the map, and select the "select
feature (0 features selected)" radiobutton, uncheck the checkbox "select features in a box".
Now hold down Ctrl and click on the feature: In my browser a new window is
opened.
Do you have an idea about how to fix this?
Best regards and thanks in advance,
Marc
