InputElementIntbox.getValue() is the same
as this method except with a different signature.
It invokes InputElement.checkUserError() to ensure no user error.

setConstraint in class InputElementconstr - a list of constraints separated by comma.
Example: no positive, no zeroprotected Object coerceFromString(String value) throws org.zkoss.zk.ui.WrongValueException
InputElementInputElement.setText(java.lang.String).
Deriving note:
If you want to store the value in other type, say BigDecimal,
you have to override InputElement.coerceToString(java.lang.Object) and InputElement.coerceFromString(java.lang.String)
to convert between a string and your targeting type.
Moreover, when Textbox is called, it calls this method
with value = null. Derives shall handle this case properly.
coerceFromString in class InputElementorg.zkoss.zk.ui.WrongValueExceptionprotected String coerceToString(Object value)
InputElementInputElement.setText(java.lang.String).
Default: convert null to an empty string.
