[Oskari-user] Bug in Suomi.fi maps - embedded maps?

Wed Oct 31 05:00:02 PDT 2018

Forwardin this message to all:

Hey, developers of the application here.

GetFeatureInfo operations are not used, but instead markers are added to
the map with the AddMarkerRequest. Then ShowInfobox windows are added to
these markers.

We believe your assessment is correct - it seems like there are two click
events when the markers overlap and user clicks on the overlapping part.
The second event indeed seems to override the first one, so the user only
sees the marker that’s closer to the map clicked.

As we were discussing this, Mikko probably found a way to select the
topmost one of overlapping markers, instead of the one closest to the map.
We’re still interested in figuring out how to properly utilize layers, for
example to draw different kinds of service locations on separate layers or
something similar.

Regarding to your questions:

- We’re not familiar with the concept of WMS layers.

- We use markers only, no features as of now.

- We’re using a hosted Oskari RPC to push them to the map.

- It does seem like the app receives multiple click events when clicking
the overlapping markers.

- When a marker is clicked, information on what the ShowInfobox contains is
passed to the popup.

- No priority numbering - we weren’t aware of this or really even how to
properly utilize layers while developing.

Best regards,

Mikko Karvonen & Samuli Vuorinen
