Predefined Constraints and Values in the Form Designer

When you edit an element of the blueprint or resource action form, you can apply various constraints and values to the element.

Constraints

The constraints that you can apply vary depending on the type of element you are editing or adding to the form.

Constraint

Description

Required

Indicates whether the element is required. The options are:

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the element you are editing to required or optional.
Field	Binds the element to another element from the form. For example, you can set the element to be required only when another element, such as a check box, is selected.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Read only

Indicates whether the field is read-only. The options are:

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the element you are editing to read-only or editable state.
Field	Binds the element to another element from the representation. For example, you can set the element to be read-only when another element, such as a check box, is selected.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Value

Allows you to set a value for the element.

Not set	Gets the value of the element from the vCenter Orchestrator workflow presentation.
Constant	Sets the element you are editing to a constant value that you specify.
Field	Binds the value of the element to a parameter of another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Visible

Indicates whether the consumer can see the element.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the element you are editing to visible or hidden.
Field	Binds the element to another element from the form. For example, you can set the element to be visible only when another element, such as a check box, is selected.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Minimum length

Allows you to set a minimum number of characters of the string input element.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the minimum number of characters of the string input element you are editing to a constant value that you specify.
Field	Binds the minimum number of characters of the string input element to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Maximum length

Allows you to set a maximum allowed number of characters of the string input element.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the maximum allowed number of characters of the string input element you are editing to a constant value that you specify.
Field	Binds the maximum allowed number of characters of the string input element to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Minimum value

Allows you to set a minimum value of the number input element.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the minimum value of the number input element you are editing to a constant value that you specify.
Field	Binds the minimum value of the number input element to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Maximum value

Allows you to set a maximum value of the number input element.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the maximum value of the number input element you are editing to a constant value that you specify.
Field	Binds the maximum value of the number input element to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

Increment

Allows you to set an increment for an element such as a Decimal or Integer field. For example, when you want an Integer field to be rendered as a Slider, you can use the value of the step.

Minimum count

Allows you to set a minimum count of items of the element that can be selected.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the minimum count of items of the element that can be selected to a constant value that you specify.
Field	Binds the minimum count of items of the element that can be selected to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to the state or constraints of the element.

For example, when you add or edit a Check box list you can set the minimum number of check boxes that the consumer must select to proceed.

Maximum count

Allows you to set a maximum count of items of the element that can be selected.

Not set	Gets the property from the vCenter Orchestrator workflow presentation.
Constant	Sets the maximum count of items of the element that can be selected to a constant value that you specify.
Field	Binds the maximum count of items of the element that can be selected to another element from the form.
Conditional	Applies a condition. By using conditions you can create various clauses and expressions and apply them to an element.

For example, when you add or edit a Check box list you can set the maximum number of check boxes that the consumer must select to proceed.

Values

You can apply values to some of the elements and define what the consumers see for some of the fields.

If you select the Not set check box, the values of the elements are automatically retrieved from the vCenter Orchestrator workflow presentation.

You can deselect the Not set check box and define custom values for an element so that the consumers can make selections, which are passed to the workflow engine. For example, when you add or edit a Check box list, you can specify predefined values for the check boxes in the list.
