Personalization - EL conditional expression based Defaulting

Summary:

Fusion Procurement. Trying to use EL Condition to decide defaulting to a field. It is working as expected but Input text field becomes display (non editable). If condition is Fales then field remains Input text only. As soon as field converts to Display only then screen does not recognize defaulting and keep giving error message saying value is required for that field.

Code Snippet (add any code snippets that support your topic, if applicable):

Field: #{node.bindings.BidCurrencyPrice.inputValue}

Defaulting Expression:

#{(node.bindings.BidVisibilityCode.inputValue == 'SEALED_AUCTION')? '0.01' : bindings.BidCurrencyPrice.inputValue}

There is no change anywhere and I can see field read only property remains false. This is happening everywhere.
