4.1

Dynamic property values depend on the value of another parameter or attribute. You define the functions by
which dynamic properties obtain values by using an object graph navigation language (OGNL) expression. If
a dynamic parameter property value depends on the value of another parameter property value and the other
parameter property value changes, the OGNL expression recalculates and changes the dynamic property
value.
IMPORTANT The use of OGNL expressions in workflow presentations is deprecated as of Orchestrator 4.1.
Using OGNL expressions in workflow presentations is not supported in releases of Orchestrator later than 4.1.
Set Parameter Properties
When a workflow starts, it validates input parameter values from users against any parameter properties that
you set.
Prerequisites
You must have a workflow and defined a list of input parameters before setting the parameter constraints.
Procedure
1 In the workflow editor, click the Presentation tab.
2 Click a parameter in the Presentation tab.
The parameter's General and Properties tabs appear at the bottom of the Presentation tab.
3 Click the parameter's Properties tab.
4 Right-click in the Properties tab and select Add property.
A dialog box opens, presenting a list of the possible properties for a parameter of the type selected.
5 Select a property from the list presented in the dialog box and click OK.
The property appears in the Properties tab.
6 Under Value, make the property value either static or dynamic by selecting the corresponding symbol
from the drop-down menu.
Option Description
Static property
Dynamic property
7 If you set the property value to static, you select a property value according to the type of parameter for
which you are setting the properties.
8 If you set the property value to dynamic, you define the function to obtain the parameter property value
by using an OGNL expression.
The workflow editor provides help writing the OGNL expression.
a
Click the icon to obtain a list of all the attributes and parameters defined by the workflow that
this expression can call upon.
b
Click the icon to obtain a list of all the actions in the Orchestrator API that return an output
parameter of the type for which you are defining the properties.
Clicking items in the proposed lists of parameters and actions adds them to the OGNL expression.
