Add-on OSGiMaskedTextField doesn't work

Hi all !

I am trying to use the add-on OSGiMaskedTextField with Vaadin version 7. But I obtained an empty field…​
Nevertheless, I have correctly instantiate an MaskedTextField element with the following code :

//===================================================//
MaskedTextField field= new MaskedTextField(“Name :”, “####-####”);
layout.addComponent(field);
//===================================================//

I tried to debug that with the Eclipse Debug but I found that the mask of the element ‘field’ is correctly set up “####-####”.
So, have you met this bug ? Can you help me to debug ?

Thank you a lot for your comprehension.
