Hi, I cannot confirm here, try the attached shapefiles: join "join2" to "join1" and use the "code06" column to do the symbology.

Thanks for testing.

For me it does not work. Table is OK, identify OK, feature counts for classes in legend are OK but everything is rendered with the color assigned to empty value (NULL).

I tried also to check/uncheck "Cache join layer in virtual memory" and "Create attribute index on join field" but no effect.

Styles based on attributes from base layer are working without problems.

Current master dae9b5d9, GDAL 1.10.1, Debian 7.
