i have just tested latest release of qgis with a simple dataset. it is polygon data - type geodatabase with some categorial columns. the one i've tested characterises land-use types in 15 categories. colum-type is integer - value range is from 1 to 15. layer properties / style / categorized / classify returns the following classification:
these values originate from the first numeric column within the corresponding attribute table - instead of the selected column.
are there any known workarounds yet ?
