Create the general functions

Add the shared unescapeHTML function to your Pega library so HTML entity codes in FlexiCapture error messages display as readable Unicode characters.

Both the single-document and the multi-document scenarios need this shared function. Create it as described in Create a function.

unescapeHTML

The unescapeHTML function converts HTML codes into Unicode characters, which is what makes error messages display correctly.

Parameters

Name	Java type	Description
htmlString	String	String of HTML codes

Return value

String, a string of Unicode characters.

Exceptions

Leave the Exceptions thrown field blank.

Java source
