Check for step's controls validity before calculating transition

[pazunino]

Hi,
In almost all cases of branching the decision is taken by a radio button selection.
Then this selection turns mandatory and this control is required in the form.
But when you click forward in the wizard the logic first check the transition and you lose the uniform criteria in validation messages.
It could be better, check for form validation and raise the required selection in the radio button.
Sorry for my English.

Pedro.
