You must also make a temporary WebLayout.
This WebLayout must then point to the temporary MapDefinition.
In one of the last lines, you redirect to the temporary WebLayout.
If that temporary WebLayout points to the temporary MapDefinition,
all should be good. (Assuming layer is visible, in range, on top, etc.).
