Description
To allow the preview and the drawing of the symbol with data-defined properties, the property is given a default value when the expression is NULL.
As a result, for DD size expression, symbols are drawn with the default size when the field is NULL. This gives different results than 2.8.
Associated revisions
converted size expr evaluate to 0 on NULL field
fix #12888
use coalesce(expr,0) to have zero size if expression evaluates to NULL
otherwise the default size would be used
