Text field expression and changing font

[dangera]

How is it possible to change font to italic when field has certain value?

 

 

[dangera]

Or should i do it with conditional style? So far nothing happened, when i added condition expression field.matches "text that needs to be italic) in a style i created.

This is the error

[Giulio Toffoli]

the expression is wrong. Here is the correct one:

 

 new Boolean ( ((java.lang.String)field_analyte.getOldValue()).equals("S.pneumonia") )
