This must be a bug, because I fail to grasp the reason for this. When I create a select form where I can select multiple objects I am allowed to set the properties of the Select all button on Select page but not on Select all. What is the difference (outside the obvious number of objects)? Now I have to create a custom select button. Regards, Ronald [EDIT] This still seems to be the case in all Mx version. Could somebody from Mendix please comment on the why?
