pageflow and exception problem
Hi again,
I've quite simple pageflow:
<pageflow-definition
xmlns="http://jboss.com/products/seam/pageflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jboss.com/products/seam/pageflow http://jboss.com/products/seam/pageflow-1.2.xsd"
name="transactionRevoke">
<start-page name="startRevoke" view-id="/setRevokeDetails.jspx">
<redirect/>
<transition name="cancel" to="revokeCancelled"/>
<transition name="process" to="checkRevokeResult">
<action expression="#{processTransactionRevoke.revokeTransaction}"/>
</transition>
</start-page>
<decision name="checkRevokeResult" expression="#{processTransactionRevoke.revokeSuccesful}">
<transition name="true" to="revokeResult"/>
<transition name="false" to="forceRevoke"/>
</decision>
<page name="forceRevoke" view-id="/forceRevoke.jspx">
<redirect/>
<transition name="process" to="checkRevokeResult">
<action expression="#{processTransactionRevoke.revokeTransaction}"/>
</transition>
<transition name="cancel" to="revokeCancelled"/>
</page>
<page name="revokeResult" view-id="/revokeResult.jspx">
<redirect/>
<end-conversation/>
</page>
<page name="revokeCancelled" view-id="/revokeCancelled.jspx">
<redirect/>
<end-conversation/>
</page>
</pageflow-definition>
and I have exception declaration in pages.xml
<exception>
<end-conversation/>
<redirect view-id="/generalError.jspx">
<message>#{messages['error.tr.failed']}</message>
</redirect>
</exception>
Now when I got RuntimeException during processTransactionRevoke.revokeTransaction() method I get veeeery long stacktrace and browser error saying
The page isn't redirecting properly
Here is my stacktrace:
10:28:11,587 ERROR [ExceptionFilter] uncaught exception
