First jdeveloper 11.1.2 bug

For start let me say that i am impressed positively with the new jdeveloper development experience.
Fast and furious
Yet I hit on the first bug already.
I used the default oracle three column layout and created a jsf page with a panel box
On runtime when I tried to disclose first empty column I got a java script error

Is it a problem of old template?
Is it a problem of combination of jspx template with Facelet page?
Will see…
Test case
