A conflict exists between two map items, one static and the other dynamic, when they refer to the same UI element. In such a case, the precedence is with the dynamic map item, no error is generated, the static map item is silently ignored.

Usually, there is no need to worry about these conflicts (mostly because static and dynamic mappings are rarely mixed, usually either only static or only dynamic mappings are used), but in case the programmer wants to know which items are in conflict with each other, that can be done using this property.
