Security and pageflows in SEAM 1.2.1GA
Hi,
I am in the process of migrating an application from SEAM 1.1.6GA to 1.2.1GA and I am having a problem with the security configuration in my application.
I use pageflows, with the transition in question being the "login" transition in the code below:
<start-page name="login" view-id="/faceletsPages/loginPage.xhtml">
<redirect/>
<transition name="alreadyLoggedIn" to="loggedIn"/>
<transition name="login" to="checkLogin">
<action expression="#{identity.login}"/>
</transition>
</start-page>When this transition executes, I get an exception as follows:
09:20:31,869 ERROR [GraphElement] action threw exception: couldn't evaluate expr
ession '#{identity.login}'
org.jbpm.JbpmException: couldn't evaluate expression '#{identity.login}'

... 64 moreThis used to work in SEAM 1.1.6. Does anyone have any ideas as to whether I am doing something wrong now?
Thanks,
