[Qgis-user] Categorizing symbols with file geodatabase

[Randal Hale]

/this might be a dupe - I finally exceeded the message size limits. /

Kristen - I did a test this morning using a file based geodatabase. I 
built one with subtypes and that appears to mimic what you are 
seeing...maybe.....Is the field that you are attempting to symbolize an 
integer of some sort?

Do you have arcgis handy (I do and can check if you wish)? Can you 
check? Right click the Feature class in Arc Catalog and click on the 
subtypes tab.
