[bpel4people] New Issue: Missing Pre-State / Post-State Specifications forAdministrative Operations

[Dieter Koenig1 <dieterkoenig@de.ibm.com>]

Target:

WS-HumanTask CD 04 revision 03, section 7.1.4 Operation Authorizations

Description:

Section 7.1.4 introduces client operations for administrative purposes.
Unlike section 7.1.1, which specifies the general-purpose client
operations, the table in 7.1.4 has no columns defining the task pre-states
in which an operation may be called and the task post-state after the
operation is performed.

Proposal:.

Add the following paragraph (copied from 7.1.1) before the table in 7.1.4:

<newParagraph>
If the task is in a predefined state listed as valid pre-state before the
operation is invoked then, upon successful completion, the task MUST be in
the post state defined for the operation. If the task is in a predefined
state that is not listed as valid pre-state before the operation is invoked
then the operation MUST be rejected and MUST NOT cause a task state
transition.
</newParagraph>

In addition, add two columns "Pre-State" and "Post-State" to the table in
7.1.4, with the following content:

+---------------------+ ... +-------------+--------------+
| Operation Name      | ... | Pre-State   | Post-State   |
+---------------------+ ... +-------------+--------------+
| activate            | ... |  Created    |  Ready       |
+---------------------+ ... +-------------+--------------+
| nominate            | ... |  Created    |  Ready       |
|                     | ... |             |  Reserved    |
+---------------------+ ... +-------------+--------------+
| setGenericHumanRole | ... |  Created    | (no state    |
|                     | ... |  Ready      |  transition) |
|                     | ... |  Reserved   |              |
|                     | ... |  InProgress |              |
+---------------------+ ... +-------------+--------------+
