Garbage in p:editor text containing HTML character entities

[krahe]

I am trying to use p:editor to edit text that may contain character entities like < or &reg;. The problem is that when a string edited by the user in a p:editor is returned to the backing bean, the character entity is replaced by the actual character it represents, plus a garbage character. For example, an original string obtained from a database might be:

Code: Select all

<h1 style="[%h1]">ENERGY STAR<sup>&reg;</sup> Performance Rating<br></h1>

After a simple edit like removing one letter from the last word, the string returned to the backing bean is:

Code: Select all

<h1 style="[%h1]">ENERGY STAR<sup>®</sup> Performance Ratng<br></h1>

Upon subsequent retrieval from the database, the special character is back in its original form, but the garbage character remains:

Code: Select all

<h1 style="[%h1]">ENERGY STAR<sup>&#194;&reg;</sup> Performance Ratng<br></h1>

The problem simply continues, with another garbage character added each time the value is edited. For instance, deleting another character results in:

Code: Select all

<h1 style="[%h1]">ENERGY STAR<sup>�®</sup> Performance Ratg<br></h1>

I don't know if this is a problem with p:editor or if something else is to blame. I'm using PrimeFaces 4.0.24, but the behavior seems to be the same with version 5.1.8.

This looks like a problem with encoding.
The application looks like it is expecting ISO-8859-1 (or some other non-UTF-8 encoding) but is actually receiving UTF-8 encoded values.
Either that or there is a filter doing something weird to the characters in the request parameter values.

It must have been an issue with my application server (GlassFish 4.1). I had to reinstall my application on a different server, and when I run my app under GlassFish 4.1 with the latest updates (the old server's code was a bit out of date), the problem went away.
