Workflow Manual / 4.4.1 Predefined Action Classes

Workflow Manual / Version 2110

4.4.1 Predefined Action Classes

These are the predefined action classes which can be performed in tasks. They can be used with the elements <Action>, <EntryAction> and <ExitAction> by specifying the name of the action class as the class attribute of the respective action element.

If an action is described as applying to one resource in an atomic variable, it can be applied to a set of resources in an aggregation variable, too.

All predefined action classes discussed here support the following additional attributes to be specified as part of the action element:

Attribute	Type	Default	Description
class	NMTOKEN	#REQUIRED	the name of the action
`successVariable`	NMTOKEN	#IMPLIED	the name of a Boolean variable that will represent whether the action was successfully executed
`resultVariable`	NMTOKEN	`#IMPLIED`	the name of a variable that will receive a possible result of the action, if any

Table 4.3. Attributes common to all actions

Furthermore, every predefined action may contain a Condition element, which will be evaluated to determine whether the action should be executed at all.

Actions can be divided into server actions which are running solely on server-side and client actions (based on the class AbstractClientAction) which are running on client and server-side.

Client-side actions

Client action classes that are used to modify resources on the GUI Client respond to the following attributes:

Attribute	Type	Default	Description
`gui`	(`Boolean`)	"true"	Defines whether a GUI element will be shown on execution of the action ("true") or not. For instance, executing `publishResources` with `gui="false"` will not show the publication window.
`ignoreErrors`	(`Boolean`)	"false"	If set to "true", this attribute makes sure that the task containing the action will continue normally after an error was encountered.
`timeout`	NMTOKEN	"30"	The timeout in seconds for the action. The default timeout is 30 seconds.

Table 4.4. Attributes of client-side actions.

ApproveResource

Use this action to approve one or more CoreMedia resources referenced by a variable. If the variable stores an explicit version, that version is approved and a place approval takes place. If no version information is present, only the place of the resource is approved.

Attribute	Type	Default	Description
`resourceVariable`	NMTOKEN	#REQUIRED	the name of the variable that contains the resource(s) to be approved

Table 4.5. Attributes of the ApproveResource action.

CheckInDocument

Use this action to check-in one or more CoreMedia documents referenced by a variable.

Attribute	Type	Default	Description
`documentVariable`	NMTOKEN	#REQUIRED	the name of the variable that contains the document(s) to be checked in

Table 4.6. Attributes of the CheckInDocument action.

CheckOutDocument

Use this action to check-out one or more CoreMedia documents referenced by a variable.

Attribute	Type	Default	Description

Table 4.20. Attribute of the UndeleteResource action.

Server-side actions

While actions on the client-side deal with resources of the Content Management Server, actions on the server-side work on workflow objects in the Workflow Server.

ArchiveProcess

Caution

The ArchiveProcess action is deprecated and should not be used anymore. It's recommended to use ArchiveProcessFinalAction instead, which can also archive data of aborted processes. See Section 4.4.2, “Predefined FinalAction Classes” for its description.

Use this action in the final task of a process to archive data of the process before it completes and gets destroyed in the Workflow Server. If the RegisterPendingProcess action was used before to add the process to some users' lists of pending processes, then these users can view the completed process in Studio's Control Room.

The action can store the process data to a MongoDB database. To configure it, set the properties mongodb.client-uri, mongodb.prefix and repository.caplist.connect in the Workflow Server. See Section 6.1, “Configuration Reference” for a description of these properties.

Attribute	Type	Default	Description
`maxProcessesPerUser`	NMTOKEN	(unlimited)	The maximum number of processes to show in the list of finished processes in Studio's Control Room. This attribute should be set to the same value for all ArchiveProcessFinalAction and ArchiveProcess actions in different workflow definitions, because all processes are stored in the same list.

Table 4.21. Attributes of the ArchiveProcess action.

Example:

The task will escalate if the process cannot be archived successfully, for example if MongoDB is down. Because of this it is recommended to retry the task as in this example:

<Variable name="finishTaskRetryTimer" type="Timer"/>
<TimerHandler class="RetryTaskTimerHandler"
              task="Finish"
              timerName="finishTaskRetryTimer"/>

<AutomatedTask name="Finish" final="true">
  <Action class="AssignVariable"
          resultVariable="finishTaskRetryTimer">
    <Timer value="30"/>
  </Action>
  <Action class="EnableTimer" timerVariable="finishTaskRetryTimer"/>
  <Action class="ArchiveProcess" maxProcessesPerUser="100"/>
</AutomatedTask>

Example 4.18. Example of the ArchiveProcess action

AssignVariable

Use this action to assign a new value to a variable. It takes a list of expressions (that evaluate to a WfValue) via the Expression subelement or WfValues via the Boolean, Date, String etc. subelements.

Example:

This example will assign Integer values to the variable defined via the attribute resultVariable.

<Action class="AssignVariable" resultVariable="resultVariable">    
    <Read variable="firstVariable" property="version_"/>
    <Expression class="AddLatestVersion">
      <Get variable="secondVariable"/>
    </Expression>
    <Integer value="4711"/>
</Action>

Example 4.19. Example of the AssignVariable element

DisableTimer

Use this action to disable a timer.

Attribute	Type	Default	Description
`timerVariable`	NMTOKEN	#REQUIRED	the variable that contains the timer that should be disabled

`timerVariable`	NMTOKEN	#REQUIRED	the variable that contains the timer that should be enabled

</AutomatedTask>

Log

Use this action to write output to the log. The log name can be defined using the facility attribute. You can write text to the output defined via the attribute message. Using the subelement Get you can output the content of variables. Define the log level using the attributes debug, error or info (see Section 4.7, “Logging” in Operations Basics for details on the logging).

Attribute	Description

facility	Define a different log facility for the output. The default log facility contains both the process and the task name. For example, the following entry in the Workflow Server's Logback configuration would match all info output of MyProcess workflows: <logger name="workflow.actions.log.MyProcess" additivity="false" level="info"> <appender-ref ref="file" /> </logger>

Attribute

Description

debug|error|info

Defines the log level "debug", "error" or "info". Value must be "true".

message
