PropertyEditorSupport setAsText not invoked

[vprucha]

Hi folks,
I'm having an issue with PropertyEditorSupport. I've got 2 classes Photo and Category. Then I have a form, you can fill in name and select category from the selectbox.

The jsp part of the form :

<spring:bind path="photo.category">
    <label for="<c:out value="${status.expression}"/>"><fmt:message key="photoform.category.name"/></label>
    <select name="<c:out value="${status.expression}"/>">
          <c:forEach var="category" items="${categories}">  value="<c:out value="${category.id}"/>"><c:out value="${category.name} ${status.value}"/></option>
        </c:forEach>
    </select>    
</spring:bind> 

I have registered my CustomEditor :

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {
        binder.registerCustomEditor(Category.class, new CategoryEditor(categoryDao));
    } 

The property editor:

public class CategoryEditor extends PropertyEditorSupport{
    protected final Log logger = LogFactory.getLog(getClass());
    private CategoryDao categoryDao;

    public CategoryEditor(CategoryDao categoryDao) {
        this.categoryDao = categoryDao;
    }

    public String getAsText() {
        Category cat = (Category) getValue();
        logger.info("Converting to int byId: " +cat.getId());
        return Integer.toString(cat.getId());
    }
    public void setAsText(String[] text) {
        logger.info("in setAsText" + text.toString());
        Category cat;
        cat=categoryDao.getCategoryById(Integer.valueOf(text[0]));
        logger.info("Setting category "+text +" name: " +cat.getName());
        setValue(cat.getId());
    }
} 

During the form setup - in formBackingObject I can see the call of getAsText, but when I submit the form setAsText is not called. It also genereates an exception:

Field error in object 'photo' on field 'category': rejected value [[Ljava.lang.String;@1fdde41]; codes [typeMismatch.photo.category,typeMismatch.category, typeMismatch.org.power_soft.photobook.bus.Category ,typeMismatch]; arguments [org.springframework.context.support.DefaultMessage SourceResolvable: codes [photo.category,category]; arguments []; default message [category]]; default message [Failed to convert property value of type [java.lang.String[]] to required type [photobook.bus.Category] for property 'category'; nested exception is java.lang.IllegalArgumentException: 58,72]

58 is the default value, 72 is the new one. I can see that String array is returned instead of string, I reckon that is the reason why it doesn't call setAsText. Unfortunately I have no clue how to get around this

any ideas why it returns the array and/or how to deal with it?
thanks Vitek

public void setAsText(String[] text) { 
        logger.info("in setAsText" + text.toString()); 
        Category cat; 
        cat=categoryDao.getCategoryById(Integer.valueOf(text[0])); 
        logger.info("Setting category "+text +" name: " +cat.getName()); 
        setValue(cat.getId()); 
    }

You have registered your property editor for Category.class, yet in your setValue you are setting cat.getId() ... probably a Long or BigInteger or whatever.

Try setValue(cat);
