Hi,
I met a problem similar to
WICKET-281<https://issues.apache.org/jira/browse/WICKET-281>.
It sill happens even after our project moves to wicket 1.2.6.
I can regenerate this error (JavaScript errors "Object expected"), when
1) submit a form which will update ListView in the same page and clear
itself through ajax
This process is a bit similar to the Guest Book Example.
2) click BookMarkablePageLink, which points to a page (includes ajax
component)
3) error happens when you click ajax component
In the html source code, you can't find wicket-ajax.js
Part of my code:
Html
<div id="detail"><p>RMA Request Details:</p>
<form wicket:id="itemForm">
<table border="0">
<tr align="left" valign="bottom">
<td width="100">Category<select
wicket:id="category">Category</select></td>
<td width="100">Product<select wicket:id="product">Product</select></td>
<td width="60">Quantity <input wicket:id="quantity" type="text"
size="5"></td>
<td></td>
</tr>
<tr>
<td colspan="3" align="left" valign="bottom"><textarea
wicket:id="reason" cols="50" rows="3"></textarea></td>
<td align="left" valign="bottom"><input wicket:id="addItem"
type="submit" value="Add"></td>
</tr>
</table>
</form>
</div>
<div wicket:id="showItems">
<table border="0">
<thead>
<tr>
<th>Category</th> <th>Product</th> <th>Amount</th>
<th>Reason</th> <th></th>
</tr>
</thead>
<tbody>
<tr wicket:id="item">
<td><span wicket:id="item_category">item_category</span></td>
<td><span wicket:id="item_product">item_product</span></td>
<td><span wicket:id="item_amount">item_amount</span></td>
<td><span wicket:id="item_reason">item_reason</span></td>
<td><a href="#" wicket:id="item_drop">Drop item</a></td>
</tr>
</tbody>
</table>
</div>
Java code
public ItemForm(String id) {
super(id);
setOutputMarkupId(true);
IModel cateChoices = new AbstractReadOnlyModel() {
public Object getObject(Component component) {
List cates = ((RMAApplication)
getApplication()).getRMAService()
.getCategories();
if(cates == null){
cates = Collections.EMPTY_LIST;
}
return cates;
}
};
IModel prodChoices = new AbstractReadOnlyModel() {
public Object getObject(Component component) {
List prods;
if(getSelectedCategory() != null){
Category cate = ((RMAApplication) getApplication())
.getRMAService().getCategoryByID(
getSelectedCategory().getId());
prods = new ArrayList(cate.getProducts());
}else{
prods = Collections.EMPTY_LIST;
}
return prods;
}
};
final DropDownChoice cates = new DropDownChoice("category",
new PropertyModel(this, "selectedCategory"),
cateChoices);
cates.setRequired(true);
final DropDownChoice prods = new DropDownChoice("product",
new PropertyModel(this, "selectedProduct"),
prodChoices);
prods.setRequired(true);
add(cates);
add(prods);
cates.add(new AjaxFormComponentUpdatingBehavior("onchange") {
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(prods);
}
});
FormComponent quantity = new RequiredTextField("quantity",
new PropertyModel(this, "quantity"));
quantity.add(new QuantityValidator());
add(quantity);
FormComponent reason = new TextArea("reason", new PropertyModel(
this, "reason"));
reason.setRequired(true);
add(reason);
add(new AjaxSubmitButton("addItem", this) {
protected void onSubmit(AjaxRequestTarget target, Form form)
{
// repaint the feedback panel so that it is hidden
target.addComponent(feedback);
target.addComponent(form);
target.addComponent(itemsContainer);
}
protected void onError(AjaxRequestTarget target, Form form)
{
// repaint the feedback panel so errors are shown
target.addComponent(feedback);
}
});
}
public void onSubmit(){
Item item = new Item(getSelectedProduct(), Integer
.parseInt(getQuantity()));
item.setReturn_reason(getReason());
Request r = ((RMASession) getSession()).getRequest();
r.addItem(item);
setSelectedCategory(null);
setSelectedProduct(null);
setQuantity(null);
setReason(null);
}
