Problem with custom property editors and Form Select TLD

[Oliver-Twist]

Hello everyone,

I am basically new to Spring, I started using Spring Framework like 1 month ago.
I use Spring 2.5.6 with webmvc module, annotations and tld.

I have a problem Custom Binding a POJO with its ID in a Select Html tag.
When I fill my form and Add the object in a list everything works, but when I try to put back the added objet in the form,
the select tag does not bind correctly.

I think there is a bug in the SelectedValueCompartor Class of
Spring that is unable tho convert integer in Spring before comparing them.

Or i simply missed something???


Let me put you in context:


Here is my pojo that I want to custom bind:

public class ItemCategory  {
    private int itemCategoryID;
    private String categoryName;

    public ItemCategory() {
    }

My Custom Property Editor for the previous object:

public class ItemCategoryEditor extends ClassEditor {
    private List<ItemCategory> list;

    public ItemCategoryEditor(List<ItemCategory> list) {
        this.list = list;
    }

    @Override
    public void setAsText(String text) throws IllegalArgumentException {
        LogFactory.getLog(ItemCategoryEditor.class).debug("text: " + text);

        if (StringUtils.hasText(text)) {
            for (ItemCategory ic : list) {
                if (text.equals(ic.getItemCategoryID())) {
                    setValue(ic);
                    break;
                }
            }
        } else {
            setValue(null);
        }
    }

    @Override
    public String getAsText() {
        LogFactory.getLog(ItemCategoryEditor.class).debug("value: " + getValue());

        if (getValue() != null) {
            return ((ItemCategory)getValue()).getItemCategoryID();
        }
        return super.getAsText();
    }
}

My Controller InitBinder method:

@InitBinder("requestCategory")
    public void initRequestCategoryBinder(WebDataBinder binder, WebRequest wr) {
        LogFactory.getLog(RequestController.class).debug("Binding!");
        binder.registerCustomEditor(ItemCategory.class, "itemCategory", new ItemCategoryEditor((List)wr.getAttribute("itemCategoryList", wr.SCOPE_SESSION)));
    }

My Form:

<frm:form modelAttribute="requestCategory">
	<fieldset>
		<legend>Item Category&nbsp;</legend>
		<br>
		<table>
			<tr>
				<td class="formLabel">Item Category</td>
				<td>
					<frm:select path="itemCategory">
						<option value="0" class="selection">Choose</option>
						<frm:options items="${itemCategoryList}"
									 itemLabel="categoryName" itemValue="itemCategoryID"/>
					</frm:select>
					<frm:errors path="itemCategory" cssClass="error"/>
				</td>
			</tr>

And finally the modelAttribute object used in the previous form that contains the nested ItemCategory object:

public class RequestCategory implements GridTagSupport {
    private int requestCategoryID;
    private Request request;
    private ItemCategory itemCategory;
    private String userID;
    private Calendar requestFrom;
    private Calendar requestTo;
    private Rental rental;

    public RequestCategory() {
    }

I have tested a Integer object to replace my int for itemCategoryID to see if the select tag bind the id correctly and it did not worked.
Also Tested a String object and it worked!
I dont really want to use this work arround, i think this feature should be fixed to work with primitive, IMO


If you have any other solutions or ideas, that would be appreciate.

Thanks in advance
