Subject Re: Calling Scala function from angular submit button
Date Wed, 09 Oct 2019 19:10:30 GMT
What I ended up doing was creating a variable that was shared between the
angular and scala instances and created a watch and case statement that
would call a function dependent on the value of the variable which would be
changed on button click.  This worked well until my company went to a YARN
cluster which apparently no longer supports the z libraries for passing
variables.  Good times....
