Hello guys!

We're trying to get the current value of the Business Unit LOV on Purchase Agreements creation screen using Page Composer, but we couldn't get any value. We tried to get the values passing the parameters in Expression Language like this: 

#{row.bindings.ReqBuId.inputValue} and we also tried #{row.bindings.ReqBuId.attributeValue}, but it's not returning any values.

We'd like to know if there's a way to get the values from a LOV using Page Composer.
