Component step - general properties
A component step represents an activity in the workflow that is assigned to one or more operations
in a component queue. See About
Component Integrator for additional information.
To specify the general properties of a component step
- If necessary, select the component step on the map, then select the General
tab in the Properties pane.
- Optionally enter a description of the component step.
- Click Add to display the Operation
Selection dialog box where you select a component, then select one or more operations for use
in this step. On return to this dialog box, the operations you selected are displayed.
If you are using Workplace or Workplace XT
and CE_Operations functionality is enabled, you can choose a predefined function that manipulates
object properties on a Content Engine. See the reference topic Using
Content Extended Operations for information and examples of usage.
- In the list of operations, select them one at a time, to display the list of parameters with
their name, data type, and access. Access rights are:
- Read (operation reads from the work item)
- Write (operation writes to a data field in the work item)
- Read/Write (a value that passes from the work item to the operation, where it is processed
and then passes back to the work item).
- The Expression field contains a named expression for your use
in specifying the value for each parameter. To associate a value with the expression, you can:
- In the workflow properties, create a data field, attachment, or workflow group with the
expression name and appropriate type for the parameter.
- In the Expression field, enter an expression using data fields, attachments, or workflow
groups already defined in the workflow.
- In the Expression field, enter a literal.
NOTE
The following restrictions apply for the expression:
- For Get and Set operations, the data type of the expression must match the type expected
in the operation.
- Only single-valued properties are supported.
- The user must have proper access rights to the properties. To get a property value, the
user must have the read access right. To set a property value, the user must have write access
to properties.
- The property must be valid for the document.
- If using CEOperations.setStringProperty() and CEOperations.setIntegerProperty() on an environment with Process Engine 4.0.x, you must enter special values (<<null>> for String or -1543210987 for Integer) to indicate that these are null values so the setStringProperty/setIntegerProperty can understand and set them correctly.
- For Process Engine 4.5.0.x, set the special values in Process Designer using the "Null" function in the Field Assignment/Expression Builder.
- You can use special characters (< > ? , . / ; ' \ ( ) * & ^ % $ # @) in document titles for CE_Operations workflows when filing documents automatically through the CE_Operations workflow using the File function. However, you cannot use documents with the double-quote (") or pipe special characters ( | ) in the document titles; the document attachments are invalid if the double-quote or pipe special characters are used.
