---------------------------------
Can't think of how to fix it but I hope this helps.
Here's a trace of where it does the conversion (xwork 2.0.4, ognl 2.6.11,
struts 2.0.11) .

> "HTML form buttons HOWTO" tutorial in Cookbook does no longer work
> ------------------------------------------------------------------
>
> Key: WW-2362
> URL: https://issues.apache.org/struts/browse/WW-2362
> Project: Struts 2
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 2.0.11
> Reporter: Sebastian
> Fix For: Future
>
>
> In the "HTML form buttons HOWTO" tutorial, it is said that "When a button is
> pressed, a parameter is set in the framework with the name and value that are
> specified as the name and value attributes of your HTML button. The framework
> converts this automatically to boolean value if an appropriate property of
> the Action is found."
> In Struts 2.0.11, this is not the case.
> The framework only converts to "true" if the parameter is set to the String
> "true".
> So the only way to get the example of the tutorial work is to define the
> input tags like this
> <input type="submit" name="buttonOnePressed" value="true">
> <input type="submit" name="buttonTwoPressed" value="true">
> This renders the example useless, as the value attribute defined the button
> text.
