Table 1‑5. Workflow Input Parameter Properties (Continued)
Parameter Property Parameter Type Description
Predefined answers All simple types Pre-defines a list of possible values for
the property as an array of simple
types. You either define the array
manually or the property calls an
action that returns an array of objects
of the appropriate type.
Predefined list of elements Any simple or complex types Pre-defines a list of possible values for
the property as an array of simple or
complex types. Calls an action that
returns an array of objects of the
appropriate type.
Show parameter input Any simple or complex types Shows or hides a parameter text box in
the presentation dialog box, depending
on the value of a preceding Boolean
parameter.
Hide parameter input Any simple or complex types Similar to Show parameter input, but
takes the negative value of a previous
Boolean parameter.
Matching expression Any parameter type obtained from a
plug-in
The input parameter matches a given
expression.
Show in inventory Any parameter type obtained from a
plug-in
If set, you can run the present
workflow on any object of this type by
right-clicking it in the inventory view
and selecting Run workflow.
Specify a root object to be shown in
the chooser. Root object is provided
from a parameter or attribute.
Any parameter type obtained from a
plug-in
Specifies the root object if the selector
for this parameter is a hierarchical list
selector.
Select as Any parameter type obtained from a
plug-in
Use a list or hierarchical list selector to
select the parameter.
Default value Any simple or complex types Default value for this parameter.
Custom validation OGNL scriptable validation If the OGNL expression returns a
string, the validation shows this string
as the text of the error result.
Data binding Any simple or complex types Binds to a property that you have
already defined in another parameter.
Authorized only Any parameter type obtained from a
plug-in
Only authorized users can access this
parameter.
Multi-lines text input Any simple or complex types Allows users to enter multiple lines of
text in the input parameters dialog
box.
Predefined Constant Values for OGNL Expressions
You can use predefined constants when you create OGNL expressions to obtain dynamic parameter
property values.
Orchestrator defines the following constants for use in OGNL expressions.
