Hi Bojan, I looked around at this zoom-in thing, but wasn't able to find
the issue. I'm not able to spend more time on it at the moment, but I have
a couple of other non-Arches open layers 3 maps on a different website
which double-click zoom in correctly, so I do think the issue must be
somewhere in the Arches code.
What I believe is happening is something along these lines: upon the
double-click event, the returned pixel values are 0, 0, which is the top
left corner of the map element. So the zoom-in function tries to use 0, 0
for the new center, causing the behavior that you see. So, somewhere we
should be able to redefine the way that the pixel position is acquired, so
that the correct center is used for the zoom.

Hi,
is there any progress with map issues with Firefox (39 and higher)? I
reported this issue (https://github.com/archesproject/arches/issues/270)
quite some time ago and I am wondering if I am the only one who is
bothered
by this issue - this bug affects all known live Arches installations.
In my country (Slovenia) Firefox is one of the most popular browsers
and my next project with Arches is aiming mostly at Slovenian users. I am
afraid that if this issue is not resolved soon, it will substantially
affect the success of the project. Is there at least some workaround for
this issue?
Thanks,
Bojan
