Checking queue for content

Question

Hi all,
I have a question concerning the mapping tool of PI. I want to know, if a queue has a real entry. When I use the function "exists", I got a "true" even when the queue has supresser. But I'd like to get a true only when the queue has a real entry (String). Could anybody help me here?
Thank You.

Hi Lukas
From your screenshot, I think you are using PI 7.0 or 7.1. I'm not sure if it behaves differently from PI 7.11 which I'm running on.
Instead of casting, you can also just declare the found variable as a String. Refer to the changes in red below.
String found = "false";
for (int i = 0; i < input.length; i++ ) {
  if (!input[i].equals(ResultList.SUPPRESS)) {
    found = "true";
    break;
result.addValue(found);
You mentioned that you received an error - can you give a screenshot of the error?
Also, can you give a screenshot of the logic and "display queue" entries of the function before the input of the UDF? I would like to the SUPPRESS and other queue values are generated.
Another thing, can you make sure that the execution type is "All Values of a Context". I can't remember how it looks like on the older XI/PI version.
