Difficulty to query with Chrome #1201

Closed rbovard closed 9 years ago

rbovard commented 9 years ago

After some tests with Chrome on an Android Tablet, I noticed that it's very hard to make a GetFeature, even after update to 1.5.3dev-20150126.

In fact, when "clicking" on the map, the map moves so the GetFeature is not fired. I tested with the native Android browser, the map doesn't move when clicking on it so it's more much simple to make a query.

I don't know if it's related to C2Cgeoportal or OpenLayers.

@kalbermattenm @gnerred Did you noticed the same behaviour?

sbrunner commented 9 years ago

It's related of OpenLayers, than witch version of CGXP/OpenLayers do you use ?

kalbermattenm commented 9 years ago

@rbovard, not as far as I know... I never heard about the "clicking-move" issue...

rbovard commented 9 years ago

CGXP branch 1.5 https://github.com/camptocamp/cgxp/commits/7814a1a514355bb5dbb965625140e68231d84ac0

I can reproduce. But if you do a very quick touch, there is no problem. But I can well understand that in administrations, the touch can be slow... ;O))

rbovard commented 9 years ago

Ha ha, thanks @gnerred !

Yes if you tap very very quickly, you have a chance to succeed but 9/10 times, the map moves...

gnerred commented 9 years ago

It is not so evident on my Samsung Galaxy tab active. I succeed 9/10 when I tap quickly (but not very very quickly)

rbovard commented 9 years ago

Hmm ok, so it's related to the hardware?

I test here with a Galaxy Tab S, I can give a try at home with a Galaxy Tab 2 to confirm that.

rbovard commented 9 years ago

I tested with a Galaxy Tab 2 yesterday evening and the issue was not present. So I think it's happening on recent tablets, which have higher capacities...

Maybe someone could test with another recent tablet to confirm that?

rbovard commented 9 years ago

@sbrunner I see that you removed the milestone, so it won't be fixed?

sbrunner commented 9 years ago

The solution I can do is to do a click with a pixel tolerance of 5px. The problem is that the longpress is managed by SenchaTouch and he can't have any tollerence...

rbovard commented 9 years ago

I just tried your example and it works a lot better than http://geomapfish-demo.camptocamp.net/1.6/mobile !!

For the record, the map is still moving on the "click" but the getfeature is fired, so I think it's a good workaround.

Thanks a lot!
