https://issues.apache.org/jira/browse/OFBIZ-6506 In Ofbiz form need to escape characters from description column in a display-entity tag to avoid XSS attacks. <display-entity entity-name="Table" description="${description}" > I tried to use bsh, as following: <display-entity entity-name="Table" description="${bsh: org.apache.commons.lang.StringEscapeUtils.escapeHtml("${description}")}"> But I get this error: Error rendering screen [component://my/widget/CommonScreens.xml#GlobalDecorator]: java.lang.IllegalStateException: This object has been flagged as immutable (unchangeable), probably because it came from an Entity Engine cache. Cannot set a value in an immutable entity object. (This object has been flagged as immutable (unchangeable), probably because it came from an Entity Engine cache.
