Hi,

Sencha Architect is missing a config called matcher when you add a validation of type 'format' into a Model.
This config should have 'object' as a type.

The good thing is that there is a workaround (you can add the config by yourself) but this can lead into errors, specially if people that are getting started with the framework starts using the tool.

Attached are 2 screenshots.
