Javadoc
Connect the validation result from the given data binding context to the
given wizard page. Upon creation, the wizard page support will use the
context's validation result to determine whether the page is complete.
The page's error message will not be set at this time ensuring that the
wizard page does not show an error right away. Upon any validation result
change,
WizardPage#setPageComplete(boolean) will be called
reflecting the new validation result, and the wizard page's error message
will be updated according to the current validation result.
