 * Offcourse the original file was provided by struts, had to modified it heavily.
 * Only the clearErrorLabels(form) function still has some very good similarity(abt 94%) with the original version
 * TODO to add errorFor attribute instead of id into the divs, since if multiple field errors are added to a particul;ar field
 * then getElementById would not be able to access them all
