> Unable to submit lists without a conversion.properties file

> Key: WW-1993
> URL: https://issues.apache.org/struts/browse/WW-1993
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.8
> Environment: Mac OSX 10.4.9, Java 1.5.0_07-87, Tomcat 5.5.20
> Reporter: Adam Ruggles
> Assignee: Rene Gielen
> Priority: Minor
> Fix For: 2.0.10, 2.1.0

> My Form looks like this:
> <form ...>
> <input type="hidden" name="invoices[0].id" value="24907" />
> <input type="text" name="invoices[0].salesOrder" value="" />
> <input type="hidden" name="invoices[1].id" value="24908" />
> <input type="text" name="invoices[1].salesOrder" value="" />
> <input type="hidden" name="invoices[2].id" value="24909" />
> <input type="text" name="invoices[2].salesOrder" value="" />
> ...
> ...
> </form>
> My Action looks like this
> /**
> * A list of Invoices.
> */
> private List<Invoice> invoices;
> /**
> * Sets invoices.
> * @param invoices The invoices to set.
> */
> public void setInvoices(final List<Invoice> invoices) {
> this.invoices = invoices;
> }
> In struts 2.0.6 the form submits and works like expected. In struts 2.0.8 I
> get a null pointer when trying to access invoices in my action (basically
> it's not coming over). I've changed nothing but the struts.
> Adding a conversion.properties file allowed me to submit the form
> successfully. According to the docs and previous versions of struts and
> webwork the Generics definition of Invoice should have been sufficient.
> Adding the new Element annotation did not solve the issue.
