[jira] [Resolved] (WICKET-3866) Typecasted TextField ignores given Type

["Martin Grigorov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/WICKET-3866?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Martin Grigorov resolved WICKET-3866.
-------------------------------------

    Resolution: Invalid

The proper way to set the type in the constructor is:
new TextField<Integer>("integer", integerModel, Integer.class);

new TextField<Integer>("integer", integerModel) is not enough because Java doesn't preserve this information at runtime (generics erasure).

> Hi,
> while reading a Integer from a typecasted TextField I realised Wicket ignores the given Type and asumes a String. Only way to get another Type is to call the Function setType(). But using a typed contructor the usage of setType() should be obsolete and the TextField should assume the given type.
> I attached a Quickstart. Simply have a look at the HomePage and comment out Line 29.
> Cheers
