org.springframework.binding.expression.ParserException: The expression
'${externalContext.requestParameterMap['gateway'] != '' &&
externalContext.requestParameterMap['gateway'] != null &&
flowScope.service != null}' being parsed is expected be a standard
OGNL expression. Do not attempt to enclose such expression strings in
${} delimiters--this is redundant. If you need to parse a template
that mixes literal text with evaluatable blocks, set the 'template'
parser context attribute to true.
I'm trying to use the instructions found this wiki page:
https://wiki.jasig.org/display/CASUM/X.509+Certificates
I've attached my login-webflow.xml file for reference.
Thanks,
Mike
