BeansBinding issue

Question

Hi all

I am using BeansBinding from java.net and i have a problem. When i sync String property from my model with the (Text) property of some (jTextField) the validator does not run when i do .bind for the first time only (my validator is to check if the jtextField is not null). While sync Float proerty from my model with the (Text) property of other (jTextField) the validator work very will. Did i misunderstod or what is the problem.

1. BeanProperty textProperty = BeanProperty.create("text");
3. BeanProperty bpDefalutPrice = BeanProperty.create("defaultPrice");
4. binding = Bindings.createAutoBinding(AutoBinding.UpdateStrategy.READ_WRITE,
5. currencyPM,bpDefalutPrice,txtPrice,textProperty);
6. binding.setConverter(new FloatConverter());
7. binding.setValidator(new FloatValidator());
8. bindingGroup.addBinding(binding);
   
   1. 1. BeanProperty bpName = BeanProperty.create("name");
   2. 1. ELProperty testName = ELProperty.create("${name}");
   3. binding = Bindings.createAutoBinding(AutoBinding.UpdateStrategy.READ_WRITE,
   4. currencyPM,testName,txtName,textProperty);
   6. binding.setValidator(new StringNotNullValidator());
   7. binding.setConverter(new StringConverter());
   8. 1. bindingGroup.addBinding(binding);
   9. bindingGroup.addBindingListener(this);
   10. bindingGroup.bind();

BeanProperty textProperty = BeanProperty.create("text"); BeanProperty bpDefalutPrice = BeanProperty.create("defaultPrice"); binding = Bindings.createAutoBinding(AutoBinding.UpdateStrategy.READ_WRITE, currencyPM,bpDefalutPrice,txtPrice,textProperty); binding.setConverter(new FloatConverter()); binding.setValidator(new FloatValidator()); bindingGroup.addBinding(binding); BeanProperty bpName = BeanProperty.create("name"); ELProperty testName = ELProperty.create("${name}"); binding = Bindings.createAutoBinding(AutoBinding.UpdateStrategy.READ_WRITE, currencyPM,testName,txtName,textProperty); binding.setValidator(new StringNotNullValidator()); binding.setConverter(new StringConverter()); bindingGroup.addBinding(binding); bindingGroup.addBindingListener(this); bindingGroup.bind();
