Problems for ClearLayers and addLayers method

[apuntovanini]

Hi!

I think there's an issue when trying to clear layers and add layers. Basically, I have a map in which i cluster 4 different layer groups. I set a little filter that hides and shows groups accordingly:

$(document).on("click", "#filters > li", function() {
markers.clearLayers();
switch ($(this).data('entity')) {
case 'Ngo':
markers.addLayer(ngos_markers);
break;
case 'User':
markers.addLayer(users_markers);
}
map.addLayer(markers);
});

The first time I click on the filters, markers do clear, and the new layer group is shown. When I try to do so second time, however, no markers are shown. I'm probably missing out something.
Can you help me out?

Thanks in advance!
Andrea

Do you end up calling map.addLayers(markers) multiple times? That might cause some issues.
That type of object is ngos_markers/users_markers. Are they arrays of markers?

Pretty certain I fixed all the issues with this, but there might be some left.

Yes, ngos_markers and users_markers are layer groups.
I also tried to remove the map.addLayer call on each click, but same results.

What's weird is that filter works just the first time and stops working for the next triggers.
Thanks again, amazing work

No news on this by chance?
Sorry to bother

Could you make a jsfiddle that reproduces the issue?
Otherwise I'll be taking a blind fiddle.
Will take a look a bit later today in either case.

I've been trying to reproduce the issue, but leaflet seems to have problems working in the jsfiddle iframe http://jsfiddle.net/apuntovanini/FKdfK/4/
Anyway, you can also check it live on our staging url http://uidue.sdconsult.in/map#11/45.6472/9.8266, clicking one of the icon filters available on the right.
Thanks again, really

You missed the css file:

Will take a look after lunch.

Yep, clearLayers wasn't quite doing the right thing. Fixed!

Check it out :)

Confirmed: it does work like a charm!
Thank you very much!!
