Question regarding the If-then-else function

Question

Hi folks ,
I have been constantly putting threads on this subject for the past day,  hope it doesn't annoy any one here.
My scenario is really simple, and i am  almost close to the solution, but there is just 1 thing missing and i know that is a very small thing, could be the context too. Hope some one can help by pointing it out>
Mapping:
In my source i have a header(0-unbounded) & detail(0-unbounded). At a given instant either header / detail will occur in source, depending on that the target node "response" will occur(0-n times)
i have achieved this in the mapping.
the problem is this:
Both the Header/Detail have a field in it called Sequence# which is mandatory and can occur only once in the Header/Detail node.
Now depending on what occurs: ie Header/Detail i need to map that particular seq# into my Target Respone's SEQ_#.
I have done the mapping for this and have done a standalone testing.
Mapping: Check if HEADER EXISTS, if yes? then map the HEADER.Seq# to TARGET.Seq#
Here are my findings:
Scenario1: 3 header nodes(No Detaili) each with a seq # in it. Out put 3 Target node each with 3 seq # in it.
Scenario2: 2 Detail Nodes(No header) each with a seq # in it. Output fails to produce the 2nd Target Structure's Seq# and Fails
When i look into the Display Queue in the mapping , i examine the iF-Then-Else function:
Since HEADER doesn't exist i c 1 Suppress in my If-Condition hence the if condition becomes FALSE., now since its false its supposed to map the seq# from my detail. (This case i have 2 ).
But in the output of the IF-Then Else, i get out only 1 seq # which is the 1st one,
What i am thinking is that the exists condition is giving out only 1 FALSE instead of 2, If there were 2 false from the exists then i would have had both the seq # in my output,
I hope my question is clear, Would appreciate anysort of help . And i apologize if I seem to be brigning up the same question over again experts.
I don't wnt to create a UDF for this matter because i know there is something i am not doing right,

Sorry I could not give my udf in my last post.
Udf1:
Create a context udf and name it as RemoveSuppress. Take two input arguments a and b. Imports: java.*;
Add this code:
   //write your code here
boolean found = false;
for (int i=0;i<a.length;i++) {
     if (a<i>.equals(b[0])) {
     found = true;
     break;
if (found == true)
     result.addValue("true");
else
     result.addValue("false");
Then it should work.
