Error Icon incorrectly placed when widget in ListEditor has constraint violation

[j.ashton]

I’m having the following problem using GXT 3.

I have a list editor and I’m using the SimpleBeanEditorDriver.

My client side model class is annotated for validation in this example: -

@Min(value = 20, message = "Amount must be at least £20")
private BigDecimal amount;

I have a button on my screen which when selected validates varies model classes including the one above and sets the driver’s constraint violations accordingly: -

final Set<ConstraintViolation<?>> allViolations = validator.validate(objectModel, groups);
editorDriver.setConstraintViolations(allViolations);

The correct fields are highlighted as in error although the error icon for the fields in my Editors (which my listEditor creates as instance of for each element in it's bound list) is wrongly located, this is sporadic and shows no easily identifiable logic. The attached image best demonstrates my findings which is that the image has been set to have a top xxx value in this case -280px which moves the icon far from where it should be (this has been discovered through firebug) note other browsers have been tried and the results are sporadic in the same way as in firefox.
