I am trying to export a pretty banal Class diagram as an image in Papyrus 1.0.1. No matter what file format I select, I always get back this error message:

Quote:
An internal error occurred during: "Generate".
com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.


In the log the exception below is registered. What is going wrong? Thank you.

Hi Luis,

This looks like an encoding issue. Do you have any special (non-ASCII) character in the diagram/model you are trying to export?

Papyrus models are supposed to be encoded in UTF-8; I'm not sure what would happen if the encoding was changed for any reason (e.g. manually editing the XML with a different encoding).

Hi Camille, thank you for the reply. I am not able to find any strange characters in the xml files:

$ iconv -f utf-8 -t utf-8 -c model.uml > model.uml.new
$ diff model.uml model.uml.new
$
$ iconv -f utf-8 -t utf-8 -c model.di > model.di.new
$ diff model.di model.di.new
$ 
$ iconv -f utf-8 -t utf-8 -c model.notation > model.notation.new
$ diff model.notation model.notation.new
$


Any other hints? Thank you.

I upgraded Papyrus to version 1.0.2 and this problem remains.

Regards.

Camille Letavernier closed this issue in Bugzilla, the fix should be available in Mars.

In the meantime, is there any hope of getting this working on Luna? Is there something I could change in the XML itself?

Thanks.
