Correct my UDF

Question

If TXT02 is null then Blank
else
OBJ=
TXT02 is under one segment say X
My logic which dint work
If X and TX02 exist and
TXT02 =(Equals ,text function) null ->if
Then " "
else TXT02="OBJ= "
actually we used BPM in this scenario.
Using the above logic,it shows error in swwl.
I tried to use a UDF.
TXT02-> if ! ( a[0].equals(null) ){
result.addValue("OBJ=");
}else{
result.addValue(" ");
The above logic doesn't throw any error in swwl,but even if TXT02=null or blank it always show OBJ=
ie it doestn't goto elsepart.
I am my using whitesapce assigned to the field TXT02 as it is one of the fields in the IDOC Segments,the Scenario is IDOC to FILE..I tried many ways using graphicl mapping it doesn't work.
Please suggest .
Thanks,

Hi,
Try following graphical mapping
Don't change any context for input fields.
                                           (if true)TXT02 --> CollapseContext -->
TXT02 --> CollapseContext -->
                                  Equals-->     If  --> SplitByValue-->TargetField
            Constant(Blank)-->
                                             (if false)OBJ--> CollapseContext -->
