How to perform addition for attribute of Number type in expression language

When adding two attributes of oracle.jbo.domain.Number type in Expression Language like EmpSal and EmpBonus as below  :

#{bindings.bindings.EmpSal.inputValue + bindings.EmpBonus.inputValue}

or adding number 1000 to EmpSal as  :

#{bindings.bindings.EmpSal.inputValue + 1000}

You may get below exception :

Unexpected exception caught: java.util.MissingResourceException, msg=Can’t find resource for bundle java.util.PropertyResourceBundle, key el.convert

To Eliminate this Exception, Add EmpSal and EmpBonus as below :

#{bindings.EmpSal.inputValue.value + bindings.EmpBonus.inputValue.value}

Add ‘value’ to inputValue to remove the exception.
