There is a requirement that we need to render rich text of html in our adobe form. As we all know that adobe doesn't know HTML but we may need to render HTML tags, for the same requirement follow below steps.
Step 1). Passing HTML to our form and set DOCPRAM-DYNAMIC = 'X'.
I created one Exporting parameter to pass my HTML rich text. You can get your HTML from SO10 also, and assign to Exporting parameter of your adobe FM.
Step 2). Create field in adobe form and set Field formate as Rich Text and bind with R_HTML.
Step 3). Then Test.
Not expected output.
Step 4). Now add below javascript on docClose event of field.
var envelope = "<?xml version='1.0' encoding='UTF-8'?>" +
"<exData contentType='text/html' xmlns='http://www.xfa.org/schema/xfa-template/2.8/'" +
"><body xmlns='http://www.w3.org/1999/xhtml' xmlns:xfa='http://www.xfa.org/schema/xfa-data/1.0/' " +
"xfa:APIVersion='Acroform:2.7.0.0' xfa:spec='2.1'>" +
"<p>"+ this.rawValue +"</p></body></exData>";
this.value.exData.loadXML(envelope,1,1);
Step 5). Now Test.
Hope this helps.
