Expression evaluation error at function a!forEach [line 104]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function 'cast' [line 106]: Could not cast from COSELM_coselm_eox_information to Number (Integer). Details: CastInvalidCould not cast from COSELM_coselm_eox_information to Number (Integer). Details: CastInvalid

You don't need the CAST. You can simply have the following: 
 a!forEach(
 items: local!productInfo,
 expression: 'type!{urn:com:appian:types:COSELM}COSELM_coselm_eox_information'(
 /* map your attributes from each instance of fv!item to your CDT attributes */
 )
 )

Note: if you want to use CAST (which is valid) you need to lose the () suffix from your type! statement i.e. 
 a!forEach(
 items: local!productInfo,
 expression: cast(
 'type!{urn:com:appian:types:COSELM}COSELM_coselm_eox_information',
 {
 /* map your attributes from fv!item to your CDT attributes here*/
 }
 )
 ) 
 This is because the instruction type!'<myType>'() is a function to create an instance of your CDT, whereas type!'<myType' is a reference to the type number, and CAST requires the type number of a type not an instance of the type.
