Here is a new JIRA https://issues.apache.org/jira/browse/WICKET-4755
I added the following code in my application class to implement what you recommended as a fix. Maybe this will help other people who run into this problem. Does this look good to you? @Override protected IConverterLocator newConverterLocator() { ConverterLocator locator = (ConverterLocator) super.newConverterLocator(); locator.set(Object.class, new BasicConverter()); locator.set(Serializable.class, new BasicConverter()); return locator; } private static class BasicConverter implements IConverter { @Override public Object convertToObject(String value, Locale locale) { return value; } @Override public String convertToString(Object value, Locale locale) { return value == null ? null : value.toString(); } } Thanks, Alec On Sat, Sep 8, 2012 at 3:47 PM, Sven Meier <s...@meiers.net> wrote: > Hi, > > Objects#convertValue()'s javadoc states that it returns null, if the value > can not be converted, thus your proposed change isn't valid for most cases. > > You could easily fix this issue in your application by registering a custom > converter for Serializable. > > Since Objects#convertValue() does more actually than "convert[ing] > numerically" (as stated in the javadoc, it handles booleans and Strings > too), I think the method could be improved, e.g by adding another > if-statement to it: > > if (toType.isInstance(value)) > { > result = toType.cast(value); > } > > Please open an issue in Jira. > > Sven > > > > On 09/08/2012 09:11 PM, Alec Swan wrote: >> >> An easy fix for this bug is to change the first line in >> org.apache.wicket.util.lang.Objects#convertValue from >> Object result = null; >> to >> Object result = value; >> >> Thanks, >> >> Alec >> >> On Sat, Sep 8, 2012 at 1:02 PM, Alec Swan <alecs...@gmail.com> wrote: >>> >>> I attached a quickstart with a test in >>> TestHomePage#formSubmitsSuccessfully. >>> >>> The test throws "'NEW VALUE' is not a valid Serializable" error when >>> "NEW VALUE" string in "value" textField is submitted as a part of >>> myForm ajax submission. >>> >>> This bug should have a high priority in 1.5 because this used to work >>> in 1.4 and there is no clear way to track down all places where this >>> needs to be fixed in the existing code base. >>> >>> Thanks, >>> >>> Alec >>> >>> On Sat, Sep 8, 2012 at 12:16 AM, Paul Bors <p...@bors.ws> wrote: >>>> >>>> Can you please put together a quick start for us? >>>> >>>> ~ Thank you, >>>> Paul C Bors >>>> >>>> On Sep 7, 2012, at 14:39, Alec Swan <alecs...@gmail.com> wrote: >>>> >>>>> Hello, >>>>> >>>>> I decided to extract this issue into a separate thread. >>>>> >>>>> I keep running into issues with default type converters in 1.5.
