Error word displays multiple times when accessibility is enabled

SA-64198

Summary



On enabling Accessibility, the 'Error:' text displays multiple times with the error message.




Error Messages



Not Applicable


Steps to Reproduce

  1. Add a post action validation to a property in a flow action rule.
  2. Run the case.
  3. Submit the form with invalid data.


Root Cause



A defect in Pegasystems’ code or rules.

pega.u.d.Axisbility.displayError API was invoked multiple times when the form was submitted. As a result, the 'Error:' text was included at the beginning of the error message for each call.



Resolution



Perform the following local-change:

Add the below script in the UserWorkForm:  


<script>
if(pega.u.d.isAccessible){ 

pega.u.d.Axisbility.displayError = function(){
varbTitleUpdated =false;
// get all error spans
var spans = document.getElementsByTagName("SPAN");
varfirstErrorFocused = true;
for(i=0; i<spans.lengthi++){
if(spans[i].getAttribute("errId") || spans[i].id=="PegaRULESErrorFlag"){ // for each SPAN hide the image and show error
if (spans[i].getAttribute("data-dl") === "1") {
/* BUG-194893 - START - For dynamic layouts, server error messages are placing as inner text of span instead of title attribute */
varerrorStr = spans[i].textContent;
try {
errorStr = (errorStr.indexOf(":")==0)?errorStr.substr("1"):errorStr;
errorStr = errorStr.replace(/^\s+|\s+$/g,'');
} catch (e) { }
varerrMsg = this.errorField + errorStr;
if(errorStr && errorStr.indexOf(this.errorField) == 0){ // this line checks if already "Error:" is there is error message
errMsg = errorStr;
}
pega.util.Dom.setInnerText(spans[i],errMsg);
/* BUG-194893 - END */
} else {
varerrMsg = this.errorField + spans[i].title;
if(errorStr && errorStr.indexOf(this.errorField) == 0){
errMsg = spans[i].title;
}
pega.util.Dom.setInnerText(spans[i],errMsg);
}
spans[i].className = "inputError";
if(spans[i].parentNode.tagName == "DIV" && spans[i].parentNode.className == "iconErrorDiv"){
spans[i].parentNode.className = "";
}
if(!bTitleUpdated){
if(document.forms[0].name=="actionForm"){
if(top){
if(top.document.title.indexOf(this.errorTitle) == -1){
top.document.title += this.errorTitle;
}
}
}
else{
document.title+=this.errorTitle;
}
bTitleUpdated =true;
}
}
}
}
}
</script>
