MapGuide Selection When Legend Hidden

[crispinatime]

When the legend is turned off on an AJAX WebLayout none of the features on the map layers are selectable.

This is a regression since 2.2 (maybe 2.1) and makes embedded applications / maps without a legend but requiring selectable features unusable.

MapGuide 2.4 RC, AJAX Map Viewer

How did MGOS < 2.1 do this? Querying for selectable layers is doing a GetLayers() against the legend frame, which doesn't exist if the legend is turned off in the WebLayout

[crispinatime]

MGOS 2.1 and 2.2 are both OK (you can select when legend is turned off).

I though it might be to do with ​http://trac.osgeo.org/mapguide/changeset/6789 but I backed out that change and the behaviour is still the same - no selectability!

I think this is actually a blocker IMHO

[crispinatime]

It was this change that caused the regression (confirmed by backing out): ​http://trac.osgeo.org/mapguide/ticket/1318

ajaxmapmape.templ calls GetVisSelLayers() from QueryFeatureInfo()

This in turn calls "GetLayers(true, true);" from legendui.templ

In the fix for 1318 there is a new check for "node.curScale" ... but this always appears to be undefined when I run a weblayout with or without a legend shown

[jng]

Not disputing the severity of this issue. Just needed confirmation that this once worked in the past.

[crispinatime]

Yes, this worked until 3 July with the 1318 patch. Appreciate that patch was for one issue but as a side effect it has created this one!

[jng]

Please try r6917 and confirm if this fixes the issue. If you installed 2.4 RC1, just svn update viewerfiles in your www directory and you'll get this change pulled down.

[jng]

Installed 2.4 RC1 with SVN metadata feature enabled. That is. Otherwise just manually edit ajaxmappane.templ as per r6917 and please confirm.

[crispinatime]

Ran SVN update to get the fix - now works as previously/expected!

[jng]

Fixed 2.4 (r6917) and trunk (r6918)
