Wicket cannot find id in inner enclosure...but has no problem in
outer one!!!
Hi,
I have two enclosure with one closing another one like this:
*<wicket:enclosure child="userType">
<table>
* <tr>
<td></td>
</tr>
* <wicket:enclosure child="post">
* <tr>
</tr>
</wicket:enclosure>
<div wicket:id="noPostLabel"></div>
</table>
</wicket:enclosure>
Here is the java code:
*ListView<UserTypeDomain> userTypeDomainListView = new
ListView<UserTypeDomain>("userType", userTypeDomainList)
{
*
@Override
protected void populateItem(ListItem<UserTypeDomain> item)
{
item.add(new Label("organization", new
PropertyModel<UserTypeDomain>(item.getModel(), "organization"))); // (4)
int organizationId =
((UserTypeDomain)item.getModelObject()).getOrganizationId();
List<PostDomain> postDomainList = null;
postDomainList = postService.getPosts(organizationId, unitId, batchId,
locationId, iModel.getObject().getKey());
}
// user posts in each user type
* ListView<PostDomain> postDomainListView = new
ListView<PostDomain>("post", postDomainList)
{
*
@Override
protected void populateItem(ListItem<PostDomain> item)
{
String post =
((PostDomain)item.getModelObject()).getPost();
item.add(new Label("text", post));
}
};
postDomainListView.setVisible(!postDomainListView.getList().isEmpty());
add(postDomainListView);
Label noPostLabel = new Label("noPostLabel", "No posts
shared till now...!!!");
noPostLabel.setVisible(!postDomainListView.isVisible());
add(noPostLabel);
}
};
userTypeDomainListView.setVisible(!userTypeDomainListView.getList().isEmpty());
add(userTypeDomainListView);
this.createModelForUserType();
}
Now, when there is no user type, then the code works fine but when there is
a type but no posts are there..i.e. inner enclosure tab is called, then the
error comes:
Root cause:
*org.apache.wicket.WicketRuntimeException: Could not find child with id:
post in the wicket:enclosure*
at
org.apache.wicket.markup.html.internal.Enclosure.checkChildComponent(Enclosure.java:249)
at
org.apache.wicket.markup.html.internal.Enclosure.getChildComponent(Enclosure.java:228)
at
org.apache.wicket.markup.html.internal.Enclosure.onInitialize(Enclosure.java:133)
at org.apache.wicket.Component.fireInitialize(Component.java:932)
....
I am not able to understand...is there any syntax mystake. I have read that
it was a bug in earlier versions of wicket but I am using 1.5. Please help
me what is causing this error...?

Hey there,
This is just a guess!!
Why are you creating a new SelectOption?;
SelectOption selectedOption = new SelectOption(selectOption[0].getKey(), "Selected Value");
when you could just use the one that exists (selectOption[0])? The PropertyModel doesn't make sense, ether. I'd remove that line above, and the property model and maybe go for, in total;
ChoiceRenderer<SelectOption> choiceRenderer = new ChoiceRenderer<SelectOption>("value", "key");
final IModel<SelectOption> iModel = new Model<SelectOption>(selectOption[0]);
final DropDownChoice<SelectOption> postCategoriesDropDown = new DropDownChoice<SelectOption>("postCategories", iModel, Arrays.asList(selectOption), choiceRenderer);
Like I said, it's a guess, but those things look strange to me... sure other people could help better. Hope it helps...
Cheers,
Col.

I have removed inner enclosure and its working fine. I am facing another problem. This is my code:
ChoiceRenderer<SelectOption> choiceRenderer = new ChoiceRenderer<SelectOption>("value", "key");
SelectOption selectedOption = new
SelectOption(selectOption[0].getKey(), "Selected Value");
final IModel<SelectOption> iModel = new PropertyModel<SelectOption>(selectedOption.getValue(), "value");
final DropDownChoice<String> postCategoriesDropDown = new DropDownChoice("postCategories", iModel, Arrays.asList(selectOption), choiceRenderer);
Select Option is :
public class SelectOption {
private int key;
private String value;
public SelectOption(int key, String value) {
this.key = key;
this.value = value;
}
/ getters and setters
}
Now here, drop down is being rendered in markup..
*<select wicket:id="postCategories">
</select>
*
But the as given in the code, I want a particular value to come as default value. But the default one is coming out 'Choose One'. What is the issue??

You can do explicitly what the enclosure does more conveniently, by using a WebMarkupContainer where isvisible() delegates to the child's isVisible().
