Affects Version/s: 220.127.116.11, 2.1.3
Fix Version/s: 2.1.8
It appears as though a class that is registered in xwork-conversion.properties that extends StrutsTypeConverter will never have it's convertToString method invoked as part of the normal ognl processing. This is most evident in the case of a converter that is required in a <s:select> tag.
An interesting thing to note is that XWorkConverter is being invoked rather than StrutsTypeConverter. Also TextParseUtil.translateVariables appears to not be able to find the correct converter in this context.
