Problem with 2
Hi,
i tried to include two Forms with a decision over transations. the first works fine, but when the second one is reached and someone claims the task> and tries to view it an unexpected exception is raised. i also tried to rename "outcome" to "outcome2" in task1.ftl but that didnt help..
Process:
<?xml version="1.0" encoding="UTF-8"?> <process name="mailprocess" xmlns="http://jbpm.org/4.0/jpdl"> <start g="220,16,48,48" name="start"> <transition to="verify_request"/> </start> <task candidate-users="peter,mary" form="email/verify_request.ftl" g="181,96,126,52" name="verify_request"> <transition g="-44,-17" name="reject" to="task1"/> <transition name="accept" to="vacation_accepted" g="-2,-42"/> </task> <task candidate-users="peter,mary" form="email/task1.ftl" g="155,187,92,52" name="task1"> <transition name="ja" to="vacation_rejected" g="-40,-13"/> <transition name="nein" to="end1" g="-42,-18"/> </task> <end g="125,307,48,48" name="vacation_rejected"/> <end g="343,252,48,48" name="vacation_accepted"/> <end name="end1" g="240,303,48,48"/> </process>
form task1.ftl and verify_request.ftl are identical:
<html>
<body>
<form action="${form.action}" method="POST" enctype="multipart/form-data">
<#list outcome.values as transition>
<input type="submit" name="outcome" value="${transition}">
</#list>
</form>
</body>
</html>Exception:
