Hi Martin,
Sorry for the <head> <body>.
I miss it.
Thanks for your insights.
In the ConstraintIterator's constructor, the set returned by the Hibernate
validation implementation (Set<ConstraintDescriptor<?>> constraints)
is unordered.
Either by calling
Set<ConstraintDescriptor<?>> constraints = propDesc.findConstraints()
.unorderedAndMatchingGroups(groups)
.getConstraintDescriptors();
or
BeanDescriptor beanDescriptor =
validator.getConstraintsForClass(IdentityRegistrationModel.class);
PropertyDescriptor propertyDescriptor =
beanDescriptor.getConstraintsForProperty(property);
Set<ConstraintDescriptor<?>> constraintDescriptors =
propertyDescriptor.getConstraintDescriptors();
As there are 2 annotations with the same type (Size) per property,
@Size.List({
@Size(min=4, message = "{firstName.sizeToSmall}"),
@Size(max=50, message = "{firstName.sizeToBig}")
})
the last call to SizeTagModifier # tag.put() wins and maxlength may be wrong
(Integer.MAX_VALUE).
The validation itself, when form is submitted, is OK.
Only the maxlenght may be wrong.
One way to fix this problem :
In the ConstraintIterator's constructor, before populating the stack,
an iteration could be made over the 'Set<ConstraintDescriptor<?>> constraints'
to find ConstraintDescriptor with Annotation's type = Size,
and if there is more than one, the biggest (=Integer.MAX_VALUE) max value
should be removed.
The other way is to add an AttributeModifier to the textfield, new
AttributeModifier("maxlength", new Model<>(50))).
Which I do.
