[kepler-dev] How actors are rendered red when exceptions occur?

[陈军]

Hi,

I want to mark actors with custom colours.

Entities in a workflow will be encircled with red colour when errors occur.
So I construct a bad workflow and run in debug mode trying to see how
actors are rendered red. But I  still can not figure out it.

Can anyone give some advice?
Thanks
