We made a stream with Modeler 15.0 and would like to open it one of the previous Modeler version.
When trying to open by double click on the stream we get the error:
Unrecognized file format
<path to file><stream_name.str>
org.xml.sax.SAXParseException: Invalid byte 2 of 3-byte UTF-8 sequence
Resolving the problem
An Documentation Enhancement request has been filled.
The stream file format was changed for Modeler 15 in order to provide smaller streams files faster.
You cannot open Modeler 15 streams in previous versions of Modeler.
Forwards compatibility is not guaranteed in any respect.
Backwards compatibility (ie. the ability to open streams created in a previous Modeler version in a newer one) is.
