I'm trying to switch from a DataView component to a GridView component
as per the GridView example at [1]. Everything worked fine with the
DataView but with the GridView (after adding a <div wicket:id="cols">
element) I get:
"WicketMessage: Couldn't find the markup of the component 'name' in
parent productList:2"
(possibly off topic, what is the ":2" part in this message?)
It's very late here, I may be making a very stupid mistake but I just
can't see it. Here's the relevant code snippets:
ProductList.html
================
<div wicket:id="productList">
<div class="product1">
<div wicket:id="cols">
<p class="product_name">
<span wicket:id="name" class="label">[Name]</span>
</p>
<img wicket:id="image" class="product_picture" />
<p class="product_details">
<a wicket:id="view" href="ProductView.html">[Details]</a>
</p>
<p class="product_price">
<span wicket:id="price">[Price]</span>
</p>
<img src="images/buy_button.gif" class="buy_button" />
</div>
</div>
</div>
ProductList.java
================
GridView dataView = new ProductDataView(this, this, "productList",
new ProductDataProvider());
dataView.setColumns(ITEM_COLUMNS);
dataView.setRows(ITEM_ROWS);
ProductDataView.java (extends GridView.java)
============================================
protected void populateItem(final Item item) {
Product product = (Product) item.getModelObject();
ProductDescription desc = ProductDescriptionService.getDescription(
product.getId(),
ProductDescriptionService.LANG_ID_DEFAULT);
if (desc == null)
desc = new ProductDescription();
new Label(item, "name", desc.getName());
new Label(item, "price", product.getPrice().toString());
new Image(item, "image", ImageUtil
.getThumbnailImageResource(product));
ProductView.link(item, "view", product.getId());
item.add(new AttributeModifier("class", true,
new AbstractReadOnlyModel<String>() {
@Override
public String getObject() {
return (item.getIndex() % 2 == 1) ? "right_products"
:
"left_products";
}
}));
}
What on earth am I doing wrong?
