[ovirt-devel] IntegerEntityModelTextBox*, NumberEntityModelTextBox*, Validate

I find the TextBox Widget of ovirt-engine,such as IntegerEntityModelTextBoxEditor. They are weak in validation. When i input a string or something else can't parse Integer. In view, the widget will make as invalid, but i press the button of "OK", it always can pass. Even, when i edit the entity's attributes, such as Random Generator's Period or Bytes per period of VM, use IntegerEntityModelTextBox* widget, it will save the old data. I can't be sure this is a fault or is normal?
