Validations
Validations are used to ensure the integrity of the information entered by the user. If the information entered is not that which is expected, an error message is displayed.
Validations are defined in the Forms Designer. Each one allows the entry of multiple conditions for the field selected with the respective error message that should appear if the condition is met.
In the Forms designer, the user will find three options: Behaviours, Validations and Actions.
Behaviours are instructions given for an attribute to change color, hide or show, depending on conditions evaluated over it.
Validations are error messages that are displayed in the web application depending on some conditions.
Actions are instructions for one or more attributes to change color, hide or show, based on conditions evaluated over other attributes.
How to Include a Validation
1. In the Forms Designer, click on the attribute where the validation will be included. Go to the Advanced option in the Properties box.
Click on the Validation link.
2. Enter the condition to be evaluated. In the first drop down list, select the object to be evaluated. Any of the attributes of the form can be chosen. The user can also write an expression or select a field that is in a related form (sub-form).
- If the first condition is Write Expression, a text box will appear where it can be entered.
- If the first condition is Select Attribute, the Select Item window will appear containing a tree with the related attributes to enable the selection.
- Then, select the operator from the list of operators the system will display. This will depend on the type of attribute being evaluated, .

To include a constant, select the “Enter Number”, “Enter Text” or “Enter Date” option and the system will display the option depending on the type of field evaluated. To include an attribute, select the option that says “Select Field” and the system will show a screen with a list of the attributes available, or if the element to be evaluated is related to a parametric entity, select the value of the entity.
3. Once the business condition has been established, enter the message that the assistant will display when the condition is met.
This will be the message shown in the Web Application:
