Bug report #11286
Updated by Giovanni Manghi over 5 years ago
The evaluation of complex Rule-Based symbols is not evaluating correctly
Add a vector layer to a map containing point data, and several fields. In the Layer Properties dialogue, under Style, change to Rule-Based. Add four rules of the form
fld_a ='AB' AND fld_b > 3 AND fld_c > 2009
fld_a ='CB' AND fld_b > 3 ADN fld_c > 2009
fld_c <= 2009 AND flb_B > 3
fld_b <= 3
Displaying the result or counting the features results in too many of symbol fld_b <= 3. No duplicates are counted.
However, if the data is added as three layers, and the query builder under the General tab is used to build expressions for fields fld_b and fld_c, the correct result is obtained
