Field configuration screen


This screen contains configuration options for an entity field: This screen has a seperate area that describes the Struts validations (if any) for this field. This is used for the automatic generation of client and server-side user input validation checks: for example, if the user enters a value for the field shown in the diagram above, it will be checked for:
  1. a null value ('required' describes a mandatory field),
  2. a value that corresponds to a 'float', e.g. 217, or 3.14159 but not "seven"
  3. maximum length.
The 'Validation XML' area contains the XML needed to support the declared validations: e.g. the example above contains the XML that configures the 'maxlength' validation to a maximum length of 10 characters.
