function _workflow_transition_form_validate_buttons in Workflow 8

Same name and namespace in other branches

1. 7.2 workflow.form.inc \_workflow_transition_form_validate_buttons()

Submit callback function for the Workflow Form / DefaultWidget.

This is only used when using action buttons in the widget. It sets the new state to proper element and sets a submit function if needed, making sure the action is executed, influencing function core/includes/form.inc/form_execute_handlers(). (While constructing the Workflow form, we were not yet aware of the submit buttons of the complete form. We try to correct this here, without adding another hook_form_alter. We guess the first button is the Save button.
