             Summary: Cast error when multiplying two unsignedBytes
                 Key: DAFFODIL-2574
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2574
             Project: Daffodil
          Issue Type: Bug
          Components: General
    Affects Versions: 3.1.0
            Reporter: Kyle Rosales
         Attachments: shortCastBug.tdml

Ran into an issue when trying to multiple two elements of type unsignedByte together in a `dfdl:occursCount`. It is causing a cast exception trying to convert java.lang.integer to a java.lang.short. I was able to work around it by casing once of the bytes as an integer ` dfdl:occursCount="\{ ../value1 * xs:unsignedInt(../value2) }”`. Attached is a tdml demonstrating the error.
