String to Double Type Coercion problem in 5.1.0.2 snapshot
I have a TextField component to input a Double.
@Component(id = "MatrixEntry", parameters ={ "validate=prop:fieldValidator"})
private TextField entry;
<INPUT t:id="MatrixEntry" t:type="text" t:value="inputValue"/>
It works fine in 5.0.18. But in 5.1.0.2 snapshot, I get the following error
when I submit the form containing the above TextField component.
Could not find a coercion from type java.lang.String to type [Ljava.lang.Double;. Available coercions: Double --> Float, Float --> Double, Long --> Boolean, Long --> Byte, Long --> Double, Long --> Integer, Long --> Short, Number --> Long, Object --> Object[], Object --> String, Object --> java.util.List, Object[] --> java.util.List, String --> Boolean, String --> Double, String --> Long

Any assistance to resolve the problem would be very much appreciated!

The error reporting could be better, but the coersion there indicates
a Double[], not a double.
