Rudy De Busscher commented on EXTVAL-82:
----------------------------------------
I did some more testing to verify compatibility with previous releases (1.2.2)
and standard JSF (without Extval)
Here are the results.
Myfaces 1.2.7
ExtVal 1.2.2
@Length(minimum=3, maximum=50) --> Validation error when field left empty
@Pattern(value={"[a-z]{3,}"}) --> Validation error when field left empty
ExtVal 1.2.3-SnapShot + javax.faces.VALIDATE_EMPTY_FIELDS = true
@Length(minimum=3, maximum=50) --> No validation error when field left
empty
@Pattern(value={"[a-z]{3,}"}) --> No validation error when field left
empty
ValidationInterceptor.isValidationStrategyCompatibleWithValue return
false since no EmptyValueAwareValidationStrategy annotation present
ExtVal 1.2.3-SnapShot + javax.faces.VALIDATE_EMPTY_FIELDS = false
@Length(minimum=3, maximum=50) --> No validation error when field left
empty
@Pattern(value={"[a-z]{3,}"}) --> No validation error when field left
empty
AbstractValidationInterceptor.validateValue because empty field and Web
parameter is set to false.
ExtVal 1.2.3-SnapShot + ExtVal-82 Implemented +
javax.faces.VALIDATE_EMPTY_FIELDS = false
@Length(minimum=3, maximum=50) --> No validation error when field left
empty
@Pattern(value={"[a-z]{3,}"}) --> No validation error when field left
empty
AbstractValidationInterceptor.validateValue because empty field and Web
parameter is set to false.
ExtVal 1.2.3-SnapShot + ExtVal-82 Implemented +
javax.faces.VALIDATE_EMPTY_FIELDS = true
@Length(minimum=3, maximum=50) --> Validation error when field left empty
@Pattern(value={"[a-z]{3,}"}) --> Validation error when field left empty
Since EmptyValueAwareValidationStrategy is now found
Myfaces 2.0.0-SNAPSHOT
ExtVal 2.0.3-SnapShot + javax.faces.VALIDATE_EMPTY_FIELDS = true
@Length(minimum=3, maximum=50) --> No validation error when field left
empty
@Pattern(value={"[a-z]{3,}"}) --> No validation error when field left
empty
ValidationInterceptor.isValidationStrategyCompatibleWithValue return
false since no EmptyValueAwareValidationStrategy annotation present
ExtVal 2.0.3-SnapShot + javax.faces.VALIDATE_EMPTY_FIELDS = false
@Length(minimum=3, maximum=50) --> No validation error when field left
empty
@Pattern(value={"[a-z]{3,}"}) --> No validation error when field left
empty
AbstractValidationInterceptor.validateValue because empty field and Web
parameter is set to false.
Without Extval
Myfaces 2.0.0-SNAPSHOT
javax.faces.VALIDATE_EMPTY_FIELDS = true
<f:validateLength minimum="3" maximum="50"/> --> Validation error when
field left empty
<f:validateRegex pattern="[a-z]{3,}"/> --> Validation error when field
left empty
javax.faces.VALIDATE_EMPTY_FIELDS = false
<f:validateLength minimum="3" maximum="50"/> --> No validation error when
field left empty
<f:validateRegex pattern="[a-z]{3,}"/> --> No validation error when field
left empty
UIInput.shouldValidateEmptyFields return false since web parameter is set
to false.
MyFaces 1.2.7
<f:validateLength minimum="3" maximum="50"/> --> No validation error when
field left empty
UIInput.validateValue doesn't do anything since the field is empty and not
required.
> Add the EmptyValueAwareValidationStrategy annotation to the Length and
> Pattern Annotations

>
> Key: EXTVAL-82
> URL: https://issues.apache.org/jira/browse/EXTVAL-82
> Project: MyFaces Extensions Validator
> Issue Type: Improvement
> Components: Property Validation
> Affects Versions: 1.2.3-SNAPSHOT, 2.0.3-SNAPSHOT, 1.1.3-SNAPSHOT
> Reporter: Rudy De Busscher
> Priority: Minor
>
> Adding the EmptyValueAwareValidationStrategy allows in JSF 2.0 that Length
> and Pattern validations are triggered (with the
> javax.faces.VALIDATE_EMPTY_FIELDS parameter set).
> They will cause a validation error with an empty string (Length annotation
> with minimum set or Pattern) so the Required annotation is no longer needed.
> Tested it out with ExtVal 2.0.3-SNAPSHOT and Myfaces 2.0.0-SNAPHOT (of 21/01)
> and it works as expected.
