Class

AJAXMultiFormTestCase

Tests that Ajax-enabled forms work when multiple instances of the same form are on a page.

Code

    // each Ajax submission, but these variables are stable and help target the
    // desired elements.

    // of field items and "add more" button for the multi-valued field within
