Can't load same demo after loading from database

[kdahlquist]

Do the following actions on beta:

• load Demo File upload web service #2 from side panel
• load a grn from the database
• try loading Demo File upload web service #2 again from the side panel--it doesn't load

I think this is because Demo #2 is still showing up in the side panel and clicking on it again doesn't do anything. I can load it from the Network menu OK.

This appears to break down into two distinct buggy behaviors:

• It should be possible to re-load the same demo; this resets the demo network to the original force-graph setup. The Network menu and Demo menu versions of this dropdown behave in this manner; we should find a way to make the sidebar version do the same
• If a demo is selected but the user then opens something different (e.g., a file or a database network), then the sidebar select element should reflect this by reverting to “Select a demo”

If it becomes necessary to separate these into their own issues, we can do so

On update-app.js we added a new function to reset the demo dropdown and called it whenever the 'Generate Network' button gets clicked; the bug seems to be fixed. I've attached screenshots of the code snippets we added to update-app.js. We're unsure if we should place this code in the generate-network.js file or keep it here. We also weren't sure if keeping lines 602 & 603 from the screenshot is necessary, for the bug seems to be fixed without them, but the other Network Mode value change listeners include them.

Go ahead and create a branch then put these changes there, and open pull request. That will let us do a code review and also try the code out live

The recommendation for how to proceed here is to start tracing where the incorrect behavior is taking place; I suggest putting a console log there while replicating the unwanted behavior to see when it gets invoked and by whom. Possible issues include:

• Unintended setting of the demoDropdownValue somewhere during the update sequence
• Unintended/overlooked setting of a web app element (via the jQuery $ function) somewhere in the sequence

I just poked around at this. The problem only happens when selecting a demo from the side panel. The behavior is correct when using the "network" or "demo" menu to load the demo.

This issue also occurs if you upload a user file in between selecting the demos from the side panel.
