When attempting to bind a Double type field from a POJO to a NumberField Vaadin Flow component in GridCrud using myGrid.getCrudFormFactory().setFieldType("temperature", NumberField.class);, a BindingException is thrown.
Steps to Reproduce
Set up a Vaadin project with GridCrud.
Create a POJO with a Double type field named temperature.
Create a grid using GridCrud and set the field type for temperature to NumberField using myGrid.getCrudFormFactory().setFieldType("temperature", NumberField.class);
Attempt to bind data to the grid.
Expected Behavior
The Double value should be correctly bound to the NumberField in the grid without any exceptions, and the values should be displayed correctly.
Actual Behavior
A BindingException is thrown with the following error message:
com.vaadin.flow.data.binder.BindingException: An exception has been thrown inside binding logic for the field element ... Caused by: java.lang.ClassCastException: class java.lang.String cannot be cast to class java.lang.Number (java.lang.String and java.lang.Number are in module java.base of loader 'bootstrap')
Environment
Vaadin version: (24.1.10)
GridCrud version: (7.1.0)
JDK version: (OpenJDK 17)
