[fusion-users] No properties shown in selection

[gnoviello]

I've modified a layer on my map to add a filter at runtime.
To do this, I made the following steps:
1) modifying the session copy of the map file
2) saving the session copy of the map file after modification
3) reloading the map on the client side 

Now, I have a problem: on this layer I can't get the properties of selected
objects, so the selection panel is always empty.
I note that the Selection.php request returns this info:

{"layers":[""],"extents":{"minx":1587194.4129254,"miny":4989233.7800054,"maxx":1587194.4129254,"maxy":4989233.7800054},"":{"propertynames":[],"propertyvalues":[],"propertytypes":[],"metadatanames":["dimension","bbox","center","area","length"],"numelements":1,"values":[[]],"metadata":[["","","","",""]]}}

where  is for the name of layer I've modified. I can see the propertynames,
propertytypes,metadatanames arrays are empty. 
Has anyone the same problem?
Thanks
Grazia
