Validation of an Edit Box control in the XPages

In the XPages the “Edit Box” controls have some settings that allow you to perform simple validations.
These settings are under the label “Validation” of the control and depend on the value of “Display Type” under the label “Data”; in the figure you can see a screenshot of the validation of an Edit Box control of type String

The result of the validation if negative can be shown on the page from the controls “Display Error” and “Display Errors”.
