+var tabIds = new Array();

The presubmit check will nag you about a missing license block in the .js file.

Also, var tabIds = [] is preferred to using new Array.

Everything in this file is fixed.

This is already tested by update in crud2.html.

This looks hard to read or edit, perhaps keeping the closing braces on their own
lines at the indentation levels that they were opened at would help (see nested
callbacks in crud2.html and other test).
