Standard activities — Extension points
|
|
The activity names listed here, known as extension points, are by design implemented at the @baseclass, Assign- or Work- level and have an empty Steps tab. These are sometimes informally known as placeholders or callbacks; they allow your application to extend the processing provided by a standard rules that are marked as final.
In your application, you can override these stubs with an activity that applies to a work type (or work pool) to implement desired processing at the events indicated. Typically, the standard calling activities noted below are marked as final, and so they cannot be overridden.
In most cases, place the overriding activity in a more specific (lower level) Applies To class.
Extension points marked with a dot (
) are part of the Process Engine API. See Standard activities
— Process Engine API.
Extension points in the Assign- class
As a best practice, override these activities using an Applies To key part that is a cover work type in your application.
Name |
Purpose |
| Assign-. NewDefaults
|
Called from Work-.NewAssign and Work-.NewAssignBasket on the assignment. Allows the developer to customize or extend the steps that are performed when a new assignment is created. |
| Assign-Service. HandleInterrupt
|
For an asynchronous service call that is interrupted by a ticket, or by a service level event (such as from the ResumeFlow service level). Can send a message to the called external system to indicate that a flow has advanced beyond the connector call, for example because a ticket was activated. Called by the RemoveAssignmentByTicket and Assign-.CompleteAssignment activities. |
Extension points in the Work- class
As a best practice, override these activities using an Applies To key part that is a work type in your application.
Name |
Purpose |
|
Work-
|
May be called by Work-.AddCoveredWork. Override to customize or extend the steps that are performed during post-processing of the addition of a covered work object using a flow action. Called by the post-processing activity of the Work-.AddCovered flow action. |
|
Work-
|
Called by
Work-Cover-.ActionCreateCover, part of the
AddCovered flow action. Override to
customize or extend the steps performed before adding a
covered object. |
| Work- .CloseDefaults
|
Called from Work-.Close. Override to include steps to occur when the work object form is closed, such as to clean up pages or properties set in Work-.OpenDefaults. |
| Work- .NewDefaults

Work-.NewCovered. Override to customize or
extend the steps that are performed while creating new
work page for the New harness. |
| Work- .OpenDefaults |

| Work- .PerformDefaults
|
Called by the Work-.Perform activity. Override to customize or extend the steps that are performed while processing an assignment. |
| Work- PreClose |
Called by the Work-.CloseWorkItem activity. Allows developers to control what appears when a user closes a work object form, such as by clicking the close box. By default, the next display is the user's worklist, but your application can call the GetNextWork activity or present a different display. |
|
Work-.ReassignDefaults
|
Called from Work-.Reassign. Override to customize or extend the steps that are performed while reassigning (transferring) an assignment to a different user's worklist. |
| Work-.ReassigntoWork BasketDefaults

Called from Work-.ReassignToWorkBasket. Override to customize or extend the steps that are performed while reassigning an assignment to a workbasket. |
| Work-.UpdateDefaults
|

class
Other extension point activities
These activities support various development and application processing.
Name |
Purpose |
| @baseclass. CheckForCustomWarnings |
|
| Code-Security. ApplicationProfileSetup |
Can perform application-specific setup after other log-on initialization is complete. Called by Code-Security.InitialProfileSetup activity. |
| Code-CachedSystemSettings. LoadApplicationDataSystemSettings |
Creates the declarative page
|
| Data-Corr-.Send |
Extended for each class derived from the Data-Corr- class. |
| Data-WorkAttach-File.CallVirusCheck |
Allows your application to call an external routine to check a work object attachment for computer viruses before it is saved in the database. Called by standard activities for each attachment type. |
| Rule-.AddApprovalDependency |
Supports customization of the rule check-in process when the rule management flow is used. Called by the Rule-.WBApproval_CheckIn activity. |
| Rule-.SetApprovalDependency |
Allows customization of check-in processing. |
| Rule-.PreCheckIn |
Called from the Rule-.WBCheckIn activity. |
| Rule-.PreCheckOut |
Called from the Rule-.WBCheckOut activity. Allows customization of check-in processing. |
| @baseclass-.PostSaveAs |
Called from @baseclass.WBSaveAs and Rule-.WBSaveAs activities. Allows customization of processing during the Save As operation for a form. |
| Rule-.OnRecover |
Allows customization of processing performed by the
Recover toolbar button ( |
| Rule-Obj-.Validate |
Extended in classes derived from the Rule-Obj- class. |
For rule types
that can have warnings, you can implement additional
custom warning checks that apply when a rule of that
type is saved. Override this activity with an activity
where the Applies To key part is a
rule type. Called by standard activities named
Rule-ZZZZ.CheckForWarnings, where
Rule-ZZZZ is a rule type. Call the standard function
addWarning(), and override the standard
decision tree
Embed-Warning.ShowWarningonForm
).
