Subject [jira] Commented: (WW-1993) Unable to submit lists without a conversion.properties file
Date Mon, 18 Jun 2007 06:36:26 GMT

    [ https://issues.apache.org/struts/browse/WW-1993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_41243
] 

Björn-H. Moritz commented on WW-1993:
-------------------------------------

The same problem here with Maps: with Struts 2.0.6 everything worked fine, with 2.0.8 I have
to add a conversion.properties. I don't get a NullPointerException but a ClassCastException.
The map is correctly set to the action, but in the map there are objects of a wrong type (Map<String,String[])
vs. Map<Integer,Integer>)

>             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

> 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.
