The expression with new ordering that works with Struts 2.5.22 seems to avoid
calling getText() when xaction.splitAssistant is null, but with the old
expression ordering (with 2.5.20) it seems the custom StrutsTypeConverter would
have received some value (possibly a null or an empty string "") when the
expression was evaluated.
As Łukasz mentioned, would it be possible for you to open a Struts JIRA ticket
for this issue ?
If you could create a very small reproducer application (one that recreates the
issue using a stripped-down custom StrutsTypeConverter based on the one you use
and a basic action with one JSP) and attach it to the JIRA that would also help
track down why the behaviour has changed with Struts 2.5.22.
Alternatively, would it be possible for you to try the old expression again
running with Struts 2.5.22, but turn on "debug" level logging and look for
DEBUG statements containing "Unable to convert value using type converter ..."
? Updating this thread with the output from one or two of those statements (if
they appear in the logs) might help narrow down a possible cause for the
behaviour in 2.5.22.
Regards,
James.
