Found a mendix default setting that has been causing me problems without me knowing it...Ill share to maybe help others
Hi There If there is no default close button on a popup. Mendix by default makes the close button on the top right hand side(X) a cancel action. This roles back the context object. So if it is a new object on a new form the object you are trying to create gets deleted. And the user can do nothing from here on it.
