The entity "nbsp" was referenced, but not declared. issue in UI Page..

Shanmuga Raj · ‎05-13-2020

I have an HTML field (text) on a knowledge base table and I want to display it's contents on a UI Page. I can get it to correct render the contents in some instances, however in some instance I get an error when rendering the Page. 'The entity "nbsp" was referenced, but not declared.'

My code :

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null" >

<div id="source-html">
<style>
table, th, td {
border: 1px solid black;
}
</style>
<button onclick="exportHTML();">Export as .doc</button>
<g:evaluate object="true" >
var sysparm_id = RP.getParameterValue("sysparam_id");
var choices = new GlideRecord("kb_knowledge");
choices.addQuery("sys_id", sysparm_id);
choices.query();
choices;
</g:evaluate>
<j:while test="${choices.next()}">
<g:no_escape>${HTML:choices.text.getDisplayValue()}</g:no_escape>
</j:while>

</div>
</j:jelly>

Anyone Help me on this. Thanks in advance

Hi,

So definitely issue with the html within the text as it is working in this case.

I believe for all other cases where the html is valid it should work

Hi,

Did you try to check the html content for that article; there must be some issue in the html content

Can you share complete UI page code?

Hi,

So when you use Try it option it gave this error?

Can you try with hard coded sys_id?
