You should pass an empty IDataProvider.

Re: how to disable the table while it is empty in wicket
Hi Martin,
I have added that code in the dataview as below.
dataView = new DataView>("AssignmentList", new
ListDataProvider(assignments)) {
public void onConfigure() {
*super.onConfigure();* *//am getting error here*
setVisible(getDataProvider().size() > 1);
}
public void populateItem(Item>
item) {
.
}
};
Also in the above code in the thread above , i have add a assignmentdb
object with empty values before form submit code, so it is loaded a table
with empty row. while onsubmit i have removed the list values and populate
the table with new values. I believe I should not add the empty values
first.How to correct this ,i have done this because wicket says
labels,dataview Ids are not defined,dataview should not be null am not aware
of how to handle the null values. please advice and help me.
code snap:
assignments.add(new AssignmentDB());
dataView = new DataView>("AssignmentList",
new
ListDataProvider(assignments)) {
public void populateItem(Item> item) {
final AssignmentDB assign = (AssignmentDB)
item.getModelObject();
item.add(new Label("AOmemberId", assign.getMemberId()));
item.add(new Label("AOlossId", assign.getLossId()));
}};

how to disable the table while it is empty in wicket
Hi Friends,
Finally i have created a program to display table with links with guidance
of you all.I have the below program which displays the data in a table
format.While the page loads initially an empty table will be shown , once
the submit button is pressed the data is populated in the table.I would like
to disable the empty table while the page loads initially. I am not aware of
ajax, also i have tried dataview.setenabled(false), it did not work.Please
help me.

Aw: Re: Exclude link from disabled hierarchy
Thanks for your respose Martin.
I maybe found another solution meanwhile. There is a method in AbstractLink
@Override
protected boolean isLinkEnabled() {
return isEnabledInHierarchy();
}
I've overwritten this by
@Override
protected boolean isLinkEnabled() {
return true;
}
Now it seems to work as expected.

Re: Exclude link from disabled hierarchy
Hi, I believe there is a ticket for such requirement but JIRA is too slow today and I cannot find it. In general this is not possible. But it is possible for links - override org.apache.wicket.markup.html.link.AbstractLink#disableLink() for this special link.

Exclude link from disabled hierarchy
Hi, I enable a Form by autorized role. Some users see the form enabled, some disabled. All works fine. My problem is that i've added a goback-link which should be enabled always for all users. But because the link is added to the form (within a button panel) it get's disabled to. Is there a smart way to exclude the goback link form "enabledInHierarchy" processing?

The flow looks OK.
Wicket creates a new instance of the page to be able to find the stateless
form inside it and submit it with the entered by the user data.
If conversion and validation passes then Wicket sets the form components'
model objects and calls #onSubmit().
Since you do #setResponsePage() in #onSubmit() Wicket will obey and
redirect to the desired page (in your case the same page).
But you say that the search engine is called twice. That means you use the
raw request parameters to make the search. It seems you don't need
conversion and validation (this is what Wicket Form component provides for
you) then you don't need (Stateless)Form at all. You just need a in
your markup that 'action' attribute points to the mount point of the page.
add(new WebMarkupContainer("form") {
@Override
public void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put("action", urlFor(ThePage.class, new PageParameters()));
}
});
There is no need to use TextField or other form components too. Use simple
HTML form elements.
