Decoupled Validation and Cross-Field Validation
- Validator objects
Validation is decoupled from Ext.form.Field.
The decoupled validators in this example are used in three ways:
1. field editor validation
2. cell validation from column renderer
3. external validation from the validate grid button
- Cross-field validation
The validator is always provided with the record so that it can
be used in validating the field.
In this example:
1. Col0 and Col1 must either both be set or both be empty.
2. Col3 must be greater than Col2
