[mapserver-users] Mapserver 7 - CLUSTER layer getfeatureinfo / php mapscript queryByPoint broken?

[thomas bonfort]

Andy: It's a known issue: https://github.com/mapserver/mapserver/issues/5205,
that requires some non trivial amount of work to fix. Funding may help to
get this fixed faster, you could contact Tamas if you wanted to go in that
direction.
Regards,
Thomas
