[mapserver-dev] CONNECTIONTYPE UNION with STYLEITEM AUTO still not working in 6.0.0-rc2 (and possible solution)

[Tamas Szekeres]

Jana,

I've just tested the SYMBOL binding with STYLEITEM AUTO and works for me. I
expect that the [icon] parameter should contain the name of a valid symbol
definition, isn't it? Could you wrap up a small example (mapfile+data) to be
able to reproduce your test case?

Best regards,

Tamas
