> DPath: Need more specific error message for invalid predicates
> --------------------------------------------------------------

> Key: DAFFODIL-1164
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1164
> Project: Daffodil
> Issue Type: Bug
> Components: Diagnostics, Usability
> Affects Versions: s15
> Reporter: Elizabeth Fahl
> Priority: Minor
>
> DPath only allows predicates as integer expressions to index arrays. With an
> invalid test, a Schema Definition Error is thrown but it seems to be trying
> to parse the predicate as a path and giving the error message that the
> element was not found.
> {noformat}
> [error] Test
> edu.illinois.ncsa.daffodil.section23.dfdl_expressions.TestDFDLExpressionsDebug.test_predicate_02
> failed:
> java.lang.Exception: Schema Definition Error: No element corresponding to
> step b found.
> {noformat}
> See tests:
