#255 PR1-REPETITION PROBLEM TERSER

[SWAROOP CHAKRABORTY]

Hi, I am trying to add field repetition for PR1 segment using a terser.set but it throws me error:
"Can't create repetition #1 of Structure PR1 - this Structure is non-repeating so only rep 0 may be retrieved"

The below is my HL7 message with 4 PR1 segments and all I want is to insert values to each PR1 segment field's components using terser.

MSH|^~\&#|||||20200301114708.448+0530||ADT^A01^ADT_A01|106701|P|2.8.1
OBX||||||||||||||||^78
OBX||||||||||||||||^78~^800|^908
OBX||^^908
PR1|654^^^654~^^^654||^^^^^654^654|^^^^^^654
PR1|1
PR1|2
PR1|3

In this case, it will insert values to the zeroth PR1 segment using terser.
This works:
terser.set("/.PR1(0)-3-6", "654");
terser.set("/.PR1(0)-3-7", "654");
terser.set("/.PR1(0)-4-7", "654");
terser.set("/.PR1(0)-1-1", "654");
terser.set("/.PR1(0)-1-4", "654");
terser.set("/.PR1(0)-1(1)-4", "654");

 but this does not,
 terser.set("/.PR1(1)-1-4", "654");

 Please help me fix this.

Full CODE:
ADT_A01 adt= new ADT_A01();
adt.initQuickstart("ADT", "A01", "P");
// adt.insertPROCEDURE(1).
for(int i =0; i<4;i++)
{
ca.uhn.hl7v2.model.v281.segment.PR1 obj = adt.getPROCEDURE(i).getPR1();
obj.getPr11_SetIDPR1().setValue(String.valueOf(i));

}



HapiContext context = new DefaultHapiContext();
Parser parser = context.getPipeParser();
String encodedMessage = parser.encode(adt);

PipeParser pipeParser = new PipeParser();
Message message = parser.parse(encodedMessage);
Terser terser = new Terser(message);
System.out.println(terser.toString());
 terser.set("/.OBX(0)-16-2", "78");
 terser.set("/.OBX(1)-16-2", "78");
 terser.set("/.OBX(1)-16(1)-2", "800");
 terser.set("/.OBX(1)-17-2", "908");
 terser.set("/.OBX(2)-2-3", "908");
 terser.set("/.PR1(0)-3-6", "654");
 terser.set("/.PR1(0)-3-7", "654");
 terser.set("/.PR1(0)-4-7", "654");
 terser.set("/.PR1(0)-1-1", "654");
 terser.set("/.PR1(0)-1-4", "654");
 terser.set("/.PR1(0)-1(1)-4", "654");
 terser.set("/.PR1(1)-1-4", "654");


System.out.println("Printing ER7 Encoded Message:");
System.out.println(message.encode());

This is because PR1 is not repeatable, but the surrounding PROCEDURE group is.

        String msg = "MSH|^~\\&|||||20200301114708.448+0530||ADT^A01^ADT_A01|106701|P|2.5\r" +
                "PR1|654^^^654~^^^654||^^^^^654^654|^^^^^^654\r" +
                "PR1|1\r" +
                "PR1|2\r" +
                "PR1|3";

        Message a01 = new PipeParser().parse(msg);
        Terser terser = new Terser(a01);

        terser.set("/.PROCEDURE(1)/PR1-1-4", "234");
        terser.set("/.PROCEDURE(2)/PR1-1-4", "345");

        System.out.println(a01.toString().replace('\r', '\n'));

and the output will be

MSH|^~\&|||||20200301114708.448+0530||ADT^A01^ADT_A01|106701|P|2.5
PR1|654^^^654~^^^654||^^^^^654^654|^^^^^^654
PR1|1^^^234
PR1|2^^^345
PR1|3
