Hi,
In the label menu of a vector Layer, choose the column to use for labeling and press APPLY. Your labels are applied in the canvas but you'll see that the attribute's listbox become empty. Then, if you do another change in the properties and press OK, you lose your labels.
If the first time, you have pressed OK after selecting your labels, you keep these labels till once again you open your Properties Dialog and press APPLY before OK.
It seems that using the APPLY button resets this field.

I don't know if i need to open a ticket for that but when using a categorized or graduated symbology, clicking APPLY erases the contents of the column listbox. But this symbology is well displayed and the next time you open the Properties dialog, the column name reappears.

I think this ticket should be closed as the issue has been fixed (it works fine since 2 or 3 days).

This is not completely fixed yet, and definitely a blocker. Seems with labeled layers of .shp file sources, clicking APPLY still clears the label's text combo box.

This occurs only in the Layer Properties dialog, not when opening the Layer Labeling Options dialog independently from the labeling toolbar.

Latest master on Mac 10.9, though pretty sure platform is inconsequential.

I Confirm on Windows.
On .shp files, both label and style column are erased.

MapInfo .TAB and .MIF files are also concerned. Not .DXF nor PostGIS tables for the formats I tried.

With latest master, I can no longer reproduce this issue with shapefiles, on Mac 10.7.5.

On master I can't see this issue anymore for the labelling dialog, but it is still there for the symbology one: strange enough when testing the issue with symbology this will affect also labelling...
