Issue with Boolean / Two Option Set field. A binary operator with incompatible types was detected.

[carterbarry88]

I came across the following issue with my trigger:

A binary operator with incompatible types was detected. Found operand types 'Edm.Boolean' and 'Edm.Int32' for operator kind 'Equal'.

I was trying to do the following for the filter expression:

new_booleanfield eq 1

In order to fix this, I changed the filter expression to new_booleanfield eq true

You cannot use the option set value for the boolean field. You have to use true or false values

[iantaylor01]

I used not(yesnofield) in my filter as the yes/no field is true or false already and so it does not require a logical test to see if it is true. So the field alone should work if set to yes and not(yesnofield) if you only want to trigger if the field is No.
