Does the new 2.0.12 version of MarkerClustererPlus fix the problem?

Sorry this does not seem to resolve the issue.
I did notice that when I drill in to a cluster on first click, then zoom back 
out till the pins re-cluster. it is at this point I'm not able to click the 
cluster to drill back down and observe the individual pins.

However, if I do reach this point of not being able to click on a cluster 
again, that if I zoom the map very far out, that indeed the clusters that I 
already clicked previous, work again but only from this high zoom level, never 
the original zoom level I first clicked the cluster.

Seeing similar behaviour to devinray -- using iPad1 ios5: click on a cluster, 
zooms in successfully. Subsequent clicks on clusters at that level don't work, 
but if I zoom out and click clusters at zoom levels higher (ie. further out) 
than the one I zoomed into originally, it works ok.

(Using this method you can kinda zoom in on an area by clicking a cluster, 
zooming in a couple of levels, zoom out a level, click on a cluster, zoom in a 
bit more, zoom out a level, etc. But obviously not ideal behaviour).

Should also point out that the demo above does work ok for me, but I'm using 
the same version of markerclusterplus as the demo (packed version), but still 
getting the errant behaviour on my build. Perhaps not playing nice with 
jquery-ui-map?

Please try all the examples at 
http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclustererpl
us/examples/ with the iPad.

Do they all work?

Sorry, I don't have an iPad to try this out myself.

Yeah, they're all good. It's an odd one. Like I say, I'm using the 
jquery-ui-map plugin as well, so it may be a conflict on that front. And the 
site that it's going onto is also bit of a beast, so there may be other 
conflicts I'm not even aware of. 

Anyway, I'm going to try and strip everything back and work my forward until it 
breaks again. Will let you know if I glean any info from that exercise.

Initial investigation would suggest it's the underlying version of jquery that 
was causing the grief. Production site was using 1.4.2. Updated my (stripped 
back) local build version to 1.7.2, and voila, all is well.

Hmm, locally, at least. Testing on staging server still shows errant behaviour, 
regardless of jquery version. Gotta be a conflict elsewhere -- will continue 
investigating (and apologies for dropping incomplete conclusions onto the 
thread!)

Here's a complex site that uses MarkerClusterPlus but NOT jquery-ui-map. Let me 
know if it seems to work for you as well.

Hi Gary, thanks for the example -- but when I click a cluster icon, I zoom in 
to a point where there aren't any subsequent clusters, so I can't check the 
errant behaviour (which is 'inbetween' clusters not working) -- if you could 
tweak it so they don't break apart at that closer zoom level (maxZoom 
property?) I'd be able to tell one way or another for sure. (No problems if 
not, trying to remove the jquery-ui-map plugin entirely from my local code to 
see if that is it).

If you zoom out far enough, then click a cluster the clusters won't all split 
apart at once (eventually they do).

Gotcha. And, yep, that works fine. It would definitely seem to be a conflict 
with something (jquery-ui-map is top of the list, but could be something else). 

I'm slowly adding in functionality to my local build to try and isolate when 
the problem kicks in.

Thanks for your help, much appreciated!

Got it! 

I was creating my markers like so...

var marker = new google.maps.Marker({
  lots of: other properties, 
  optimized: false
});

I'm animating all my markers on mouseover of another element to set the marker 
bouncing; setting optimized to false made the start of the animation smoother. 

Anyway, it was this optimized property that was the issue. Setting this to true 
fixed the issue (it also broke the smoothness of my animation effect, but since 
you can't mouseover in a touch device, I can set the optimized value 
accordingly). 

Phew.

Well, you've got a workaround. I'm still not sure whose bug this is -- Google, 
jquery-ui-map or ???

Original comment by garylitt...@gmail.com on 14 Aug 2012 at 3:51

[GoogleCodeExporter]

I think jquery-ui-map is off the hook on this one. I removed it entirely and 
the problem remained. 

Looking around the boards, there's at least a couple of issues open with 
regards to that optimize property, particularly in regards to custom markers 
(which I'm also using) -- so I suspect that's the root of the problem (what the 
actual problem is, however, is beyond my ken).
