Clicking on NavTree Block Library clears BlockEditor #297

Open AnmAtAnm opened 6 years ago

AnmAtAnm commented 6 years ago

Expected:

Clicking a block library in the NavTree should not have any effect in the active editor.

Observed:

Clicking a block library node will clear the BlockEditor workspace, which causes the following exception:

Uncaught TypeError: Cannot read property 'getFieldValue' of null

I have the same problem.

Are you fixed?

AnmAtAnm commented 6 years ago

Sorry. I haven't fixed this one, but working towards it (juggling lots of projects right now).

For what it is worth, I don't consider this project release ready, yet. Hence the lack of announcement. Feel free to file bugs (and pull requests, maybe?) if you find it more useful than the current Developer Tools.

The root issue stacktrace appears to be:

chrome-extension://ihlmgmhlghhhacdmnkflmddmgodfaoll/src/view/navigation_tree.js:372
      throw 'Name of resource associated with node element is null or empty. ID' +
      ^

This thrown error prevents the editable workspace from initializing, and all references to the BlockEditorController rootEditorBlock fail with Cannot read property '___' of null
