public class WorkflowTaskFormHandler
A form handler for operating on workflow tasks.
This bean has four properties which together uniquely identify
the task being operated on by the form handler:
processName
, segmentName
,
subjectId
, and taskElementId
. It also
has the following read-only properties which can be accessed once
the task's identifying information has been specified:
The form handler's submit methods operate on the task on behalf of the WorkflowView associated with the form. The following submit methods are supported:
newPriority
property
newOwnerName
property
outcomeElementId
property
The following properties of the WorkflowTaskFormHandler will typically be set in the properties file for this component:
subject
property; the default is
"atg.workflow.servlet.WorkflowTaskFormSubject" (see below for
details)
The following properties will typically be set in the jsp page:
setTaskPriority
submit method
setTaskOwner
submit method
fireOutcome
submit method
When operating on tasks, it is common to want to update the workflow subject as it gets advanced through the workflow. For example, a manager in an expense report workflow may be required to submit a comment as part of approving or rejecting an expense report. The comment field is typically a property of the workflow subject (the expense report).
To facilitate subject updates without the need for custom code,
WorkflowTaskFormHandler exposes a special subject
property of type WorkflowTaskFormSubject (or a subclass specified
via the subjectClassName
property). Using this
property, one can set subject values as follows:
<dsp:textarea bean="WorkflowTaskFormHandler.subject.value.comment" cols="35" rows="5" default=""></dsp:textarea>When the
updateSubjectOnSubmit
property is set to
true, the values set via the subject
property are
copied over to the workflow subject when any of the submit methods
are executed.
Finally, the WorkflowTaskFormHandler has a set of properties which are used to control navigation after a form operation has been completed. These properties specify the URLs to redirect on certain error and success conditions. If the value for a particular condition is not set, the form is left on the page defined as the action for that form (i.e. no redirect takes place). Each operation has its own successURL and errorURL properties. These properties can be specified either in the properties file of the form handler, or in the jsp page via hidden tags.
Instances of this form handler should be request-scoped.
