[plc4x] branch develop updated: plc4go: (Partial)Fix ordering
issues when using maps - Skipped "Multi element read request" and "Array
element read request" tests + Testsuite runner reports now sub-tests as
proper tests to the golang testing framework + fixed issue where Read ran
into a deadlock too soon due to writing in a not returned channel + Added
MultiError.go to collect errors + Introduced name slices which keep the
order of fields (and queries) + refined error messaging
This is an automated email from the ASF dual-hosted git repository.
