Bart,

I think It is this one: http://trac.osgeo.org/mapserver/ticket/2444. Patch is in the bug.

best regards,

Hi James,

all data sources are PostGIS. I am sure the WFS request is valid.

It only happens if I click somewhere where one of the two layers has no data, 
if I click somewhere where both layers have data all is fine.

Best regards,
Bart

Hi Bart,

I imagine you've thought of these (and from your post that you are
sure that your WFS request is valid - and that it should be returning
data) - but just in case:

- Does this happen all the time - or only on some areas / requests ?
We have had issues with certain more complex gemometry types - or some
geometries that are questionably formed

- Where is the data coming from ?
We've had issues with data sources that can supply mixed geometry
types - or even I think grouped layers where it included perhaps
points for one zoom level and polygons for another

Sorry - can't help with version numbers - don't keep track of that
stuff too carefully

Good luck

Hi list,
I need someone with a good memory on Mapserver history :-)
I am running into what I believe is an old bug in Mapserver WFS,
unfortunately we are still running an old MS 5.0.0.
When doing a WFS query and one of the layers returns an error (like no
matching records found), no feature collection is returned but only the
error message.
Can someone remember this bug, and also if there is a workaround, if no
workaround then in what version was this fixed? TIA.
