[jbpm-issues] [JBoss JIRA] Commented: (JBPM-1352) Support Seam use cases

[ https://jira.jboss.org/jira/browse/JBPM-1352?page=com.atlassian.jira.plug... ] Tom Baeyens commented on JBPM-1352: ----------------------------------- i've plugged in jsr 223 with scripting.dev.java.net. in the configuration, you can configure a named list of expression languages and also indicate which is the default expression language. in the jpdl language, for each expr attribute, there is an optional lang attribute. ok. my expectation is that you drive the seam integration. i'll be ready to supply any jbpm update that you'll need and re-upload a snapshot. does that work for you ? regards, tom.
