Money Data Type Attribute Issue

If you faced [Object reference not set to an instance of an object.] error on creating new record; and you confirm is not javascript problem...
then it might be the CRM4 Money Data Type issue.

Scenario: Let say you created a money data type field in custom entity, then you realise you select the wrong data type and remove it. (should be number instead of money).

If you add a Money data type and then delete, you probably will hit this error unless you still have others money attribute in that Entity.

Create at least one attribute with Money data type to solve the problem.
Just don't display the field if you don't wan it, but it must exist in entity.
