Subject: [bpel4people] NEW ISSUE: Getting all task details in a single request

 

 

TARGET: WS-HT

 

DESCRIPTION:

 

Currently, the WS-HT interface is fine grained.  If an application wants to present the user with all the information about a task on a single screen (other than the contents of the attachments, which are accessed separately), then it would be necessary to call all of the following operations in the current interface:

-          getAttachmentInfos

-          getComments

-          getRenderingTypes

-          getRendering

-          getTaskInfo

-          getTaskDescription

-          getInput

-          getOutput

-          getFault

-          getOutcome

 

PROPOSED RESOLUTION:

 

We should add an operation called: getTaskDetails which returns all of the information about a task other than the contents of its attachments.  This operation takes a task ID as input and returns a union of the contents returned by the operations listed above.  Some of the operations above require an additional parameter to get a specific item (getRendering, getTaskDescription, getInput and getOutput).  The getTaskDetails operation returns all valid return values of these operations for the given task ID (all renderings, task descriptions, inputs and outputs).
