If you have followed these instructions:
File Geodatabase (*.gdb) support in QGIS?
you should be able to load the gdb directory (and layer) in the dataset text box.
I checked your suggestion.
(1) During installation using QGIS-OSGeo4W-2.2.0-1-Setup-x86.exe, there is no such option was available to select/enable gdb components.
(2) After installation, while adding vector layer using the 'source-type' value as 'UK.NTF2' and a fileGDB as dataset, It shows an error message 'Invalid data source'.
How to fix this issue?
