Printing custom error Messages in Messages column in WEBADI Excel Template

Question

I have created a Custom PL/SQL API and Custom integrator to upload data in our Custom Table for Receipts and Payments.
Im printing error messages using the RAISE APPLICATION ERROR in the Messages Column of webadi upload spreadsheet. However the error message is getting truncated to 100 characters. Does anyone know why ?
eg: In my PL/SQL API code is RAISE_APPLICATION_ERROR(-20001,V_MESSAGE);
I saw in oracle that v_message length can be 2048 bytes (512 characters)..then why is it truncating it
Thanks

I think I've resolved this myself (with reference to a few different forum posts!) by changing the javascript in the Error Page Template to:
<script language="javascript">
function getElementsByClass(searchClass,node,tag) {
var classElements = new Array();
if ( node == null ) node = document;
if ( tag == null ) tag = '*';
return node.getElementsByTagName(tag);
function show_error_text() {
errorElements = getElementsByClass("ErrorPageMessage",document,"div");
if (errorElements.length > 0 ) {
errorText = errorElements[0].innerHTML;
search_term = "SSL";
str_check = errorText.indexOf(search_term);
if (str_check==-1) {
search_term = "QMS";
str_check = errorText.indexOf( search_term );
if (str_check > 0) {
errorText = errorText.substr(str_check);
errorText = errorText.substr(0,errorText.indexOf("ORA")-1);
errorText = errorText.replace(/#/g,"~");
url_location = "f?p=&APP_ID.:200:&APP_SESSION.::NO::P200_ERROR_MESSAGE:"+errorText;
window.location = url_location;
show_error_text();
</script>
We know our error codes will always start with SSL or QMS. So this will pass the bit of the Oracle error we're interested in to P200_ERROR_MESSAGE or the full Oracle error if it hasn't been raised by some of our code.
