Can't create boundary event registry in Flowable opensource 6.8

I am reading this tutorial

I added a boundary event registry. But validation shows me error. I am on Flowable opensource 6.8. How can I get it working?

I guess boundary event registry is not supported in Flowable open source 6.8. I created one in Flowable cloud. Boundary event registry becomes boundary timer registry after importing to Flowable open source 6.8.

@martin.grofcik Any suggestion? Thanks!

6.8 → use flowable ui designer. Eclipse plugin can be out of date. Or deploy model from cloud designer directly to 6.8.x engine. The differences are small.

Thank you for your suggestion!

I found out the issue was due to some alignment issue in modeler. I had to align them very well to get it working. Some similar issues on alignment
