-----------------------------
Resolution: Fixed
> RegexFieldValidator not working correctly on IBM JVM - xml validation files
> ---------------------------------------------------------------------------
>
> Key: WW-3066
> URL: https://issues.apache.org/jira/browse/WW-3066
> Project: Struts 2
> Issue Type: Bug
> Components: XML Validators
> Affects Versions: 2.1.6
> Environment: IBM WAS 7.0
> Reporter: Tomasz Filak
> Priority: Major
> Fix For: 6.1.0
>
>
> We use -validation.xml files in our struts2 web application. Validation
> worked fine on Tomcat but since we migrated to Websphere 7.0, we have noticed
> strange behaviour of the XWork Validator framework. After some debugging we
> found, that the reason was RegexFieldValidator.getTextValue(Element valueEle)
> method.
> On IBM JVM, XML expressions containing XML entities (such as & or > )
> are parsed as separate nodes, so following configuration:
> <field-validator type="fieldexpression">
> <param name="expression">( (placeId != null && placeId >
> 0))</param>
> <message>String required</message>
> </field-validator>
> resulted in following Nodes being bassed to
> RegexFieldValidator.getTextValue() method:
> ( (placeId != null
> &
> &
> placeId
> >
> 0))
> After merging those nodes, getTextValue returned this String: "( (placeId !=
> null & & placeId > 0))."
> Additional space were added added between nodes, which broke the whole
> expression. The same behaviour was noticed when using CDATA tag.
> Our quick-fix was to override the RegexFieldValidator.getTextValue() to
> delegate to DomUtils.getTextValue() method.
> Best regards.
