I'm having a problem with a custom block type I created. Clicking the 'Update' or 'Add' button when editing/creating a block results in a javascript alert that simply says 'undefined'. This error occurs with Internet Explorer no matter what data is entered into the fields. With Firefox it shows the alert only if the first fields is left blank, otherwise it works fine.
I've tried delving into the javascript code that controls the ccm-form-submit-button, but it is quite difficult to see what's happening and where.
Does anyone know what could be causing this? Any tips where and what to look for?
