Re: how to disable the table while it is empty in wicket
Hi, Sorry. I don't have time to write sample applications for all the problems Wicket users have. If you create a mini application and share it with us (as attachment or a project at GitHub/BitBucket/...) then we could check it, fix it and send it back to you.

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.
Code:
Homepage.java:
public class HomePage extends WebPage {
ArrayListAssignmentDB assignments = new ArrayListAssignmentDB();
DataViewListlt;AssignmentDB dataView ;
private String memberNumber,lossNumber;

PropertyModel lossIdModel=new PropertyModel(this,lossNumber);
TextField memberIdField = new TextField(memberId,memberIdModel);
TextField lossIdField = new TextField(lossId,lossIdModel);
assignments.add(new AssignmentDB());
dataView = new DataViewListlt;AssignmentDB(AssignmentList, new
ListDataProvider(assignments)) {
public void populateItem(ItemListlt;AssignmentDB item) {

item.add(new Label(AOmemberId, assign.getMemberId()));
item.add(new Label(AOlossId, assign.getLossId()));
Link link1 = new Link(AssignmentIdLink){
public void onClick()
{
System.out.println(Linkclicked+ assign.getMemberId() + +
assign.getLossId() );

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 DataViewListlt;AssignmentDB(AssignmentList, new
ListDataProvider(assignments)) {
public void onConfigure() {
*super.onConfigure();* *//am getting error here*
setVisible(getDataProvider().size() 1);
}
public void populateItem(ItemListlt;AssignmentDB
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 DataViewListlt;AssignmentDB(AssignmentList,
new
ListDataProvider(assignments)) {
public void populateItem(ItemListlt;AssignmentDB item) {
final AssignmentDB assign = (AssignmentDB)
item.getModelObject();
item.add(new Label(AOmemberId, assign.getMemberId()));
item.add(new Label(AOlossId, assign.getLossId()));
}};

You should pass an empty IDataProvider.
In your case an empty list.
