I got a strange behaviour by using hibernate validators:

I take that:

In my entity-Bean, I use the hibernate-validator-tags:

Code:
@Length(min=4)
@NotNull(message="No Password")
@Column(name = "PASSWORD", nullable = false)
public String getPassword() { return password; }


I integrated the validator in an xhtml-page by using the Seam-Tag <s:validate/>. I got the following exception:

Code:
...

The strange thing is, when I use the Tag "@Length" instead of "@NotNull" or "@NotEmpty", than my page with the hibernate validations works well.

Code:
@Length(min=1)
@Column(name = "PASSWORD", nullable = false)
public String getPassword() { return password; }


Why is that so? I wanna use @NotNull or @NotEmpty. to validate, that the field 'password' does not be empty. What is wrong?

okay, now I am using the "required="true"-Attribute. Then the validation works. But also without the @NotNull.

So how can I use the @NotNull instead of "required="true" ??

This validation works (validate the length):

Code:
 
@Length(min=4, max=60)
@Column(name = "PASSWORD")
public String getPassword() { return password;}


but this validation works NOT:

Code:
@NotNull
@Column(name = "PASSWORD")
public String getPassword() { return password;}

I have also encountered the same problem. For some reason, the field is populated with empty String(""). JSF defect? or Seam defect?
