Tabs blank with javascript error

Page with four tabs. First tab loads fine. Remaining tabs are blank.

Here’s what I’m getting in the console:

Uncaught TypeError: Cannot read property ‘Id’ of undefined

It’s apparently pointing to line 3417 of skuid_SkuidJS:

Found it!

Custom component was pointing to an empty model - I messed up the model conditions.

HA!  Even the best…
