Method Detail

selectValues

Override this method to provide the values for the options. These will be the possible values returned by the form's input and should be the possible values for the JSON argument.

Returns which value should be selected. This is *not* the default value itself, as the default values may be of any type, but the input value that should be selected in the browser.

selectNames

Override this method to determine the value names, that is the names displayed in the browser. Return null, if the value strings should be used (this is default behavior).

protected java.lang.String queryElement()

Displays the query element. It is a select tag with option tags inside. If the argument is required then additional empty value is added with name "Please select..." that ensures that the user selects actual value.
