* function which gets called whenever the administrator selects an association via the modal),

/**
* Propagate associations from this field into other association fields
*
* This function is called whenever an administrator populates an association (in the association
* modal field) and then clicks on the Propagate button.
* The purpose of this function is to find what other records (if any) are associated with the
* one which the administrator has selected, and populate the other association fields with these
* records. (Otherwise, if the administrator just clicks on Save without clicking on Propagate,
* those other associations will be deleted). It does this by finding the id of the selected
* associated record (from a hidden field) and makes an Ajax call to the server to find the other
* associations, also passing up the language of the record currently being edited, as it should
* be excluded. Once it has received from the server the other associations it calls
* injectAssociations to inject them into the other association fields within the form.
*
* @param fieldPrefix The stem of the html ids for the elements comprising the
* modal field
* @param callbackFunctionPrefix The name of the callback function which the modal window uses
* to set the selected item as the association, but minus the
* language tag at the end
*
* @return boolean
