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"/>

| <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:
Expression outcome is undefined on line 7, column 8 in email/task1.ftl.
| The problematic instruction:
| ----------
| ==> list outcome.values as transition [on line 7, column 1 in email/task1.ftl]
