Flowable Modeler CMMN export import problem

Flowable Engine
1

I am using Docker flowable/all-in-one.
And when i am exporting a (simple) cmmn file and try to import it, it fails with the message:

Error while processing the CMMN XML file : Import failed for [*].cmmn.xml, error message null

Based on the errorlog it looks like creating an image will result in this error.

At this moment i see there is a new version of flowable released. Will this also lead to a new flowable/all-in-one docker image?
And is the problem mentioned above fixed?

Hey @Teyep,

Can you please try the latest flowable/flowable-ui docker image and tell us if it works?

The flowable/all-in-one image is no longer published, we are publishing flowable/flowable-ui now.

Cheers,
Filip
