sharing angular variable to scala interpreter in zepelin

Hi


In one of my usecases, i need to pass a variable defined inside angular
interpreter to another paragraph which is a scala interpreter. I could do
other way around using z.angularBind() but could not figure out how to pass
a variable from angular to scala. Any clue will be helpful here
regards
Bala

Creation of AngularObject from front-end will be possible once those PR are
tested and merged:

Hi,

Once an AngularObject is created, updated value from front-end side
(angular interpreter) automatically propagated to the back-end side. So
SparkInterpreter can read it using z.angular().

However, creation of new AngularObject is possible only from the backend
side at the moment.

So, you'll need call z.angularBind() from backend side for all your
variables.

Thanks,
moon
