Dennis Gove commented on SOLR-8918:
-----------------------------------
I've found the problem and in doing so developed a slight dislike for angular
(but really it was my own fault because I know all about javascript global
states and what not).
stream.js was created from a copy of cloud.js. cloud.js created a global
variable called graphSubController. When I was mucking around with stream.js I
kept the graphSubController global variable but re-implemented it. Now, when
angular runs it will process all the .js files and in doing so the
stream.js::graphSubController replaced cloud.js::graphSubController so the
correct sub controller was not being called from the cloud.js code page.
I'll have a patch to fix this in a little bit - after I go and cleanup all the
alerts I added to figure out what in the world was going on.
(in reality though, it was pretty fun to learn-ish angular for this)

> Add to the admin page an ability to work with and view Streaming Expressions.
> This tab will appear under the Collection selection section and will work
> similarly to the Query tab. On this page the user will be able to enter a
> streaming expression for execution. The user can then execute the expression
> against the collection and view all the results as they are returned from the
> Stream handler. Along with this the user will be able to view the structure
> of the expression in a graph-like layout.
> If the user wishes to only view the expression structure without executing
> the expression the user will be able to click an "Explain" button which will
> show the structure. Included in the structure will be information about each
> node (the expression for that node).
