hi, since version 5.6.0 i cant delete values in a context variable. when i try to delete anything i will set the old value back how can i set it to empty so that my "if(!context.datum.equals(""))" will work again?
At first empty is not cleared, it is simply an empty string. null would be a reasonable initial value. Is the datum field a Date or a String? In case of String I would ask: if (context.datum.isEmpty() == false)
