Re: Unable to retrieve row model in DataTable while running the application in Jetty

[Francois Meillet]

Hi James,

Do you use the same DataProvider for your DataTable ?
Do you use the same model when you override DataTable # IModel model(T 
object);
Do you call detach ?

Unable to retrieve row model in DataTable while running the application in Jetty

[James Selvakumar]

Hi all,

I have a DataTable with some ajax links in the first column. Other columns
are simple property columns. The ajax links are used to edit/delete
associated entities. The ajax links are encapsulated inside a panel.

The DataTable itself is rendered fine.

The problem I face is that the rowModel.getObject() is null when any of the
ajax link is clicked when running the application in Jetty (Maven jetty
plugin).  However, if the application is deployed on Tomcat, everything
works as expected.

Can anyone highlight my mistake, if any here?

Here's how my code looks like:

List columns = new ArrayList();
columns.add(new AbstractColumn(Model.of(getString("name")), "name")
{
@Override
public void populateItem(Item cellItem,
String componentId, final IModel rowModel)
{
cellItem.add(new DataTableActionPanel(componentId,
rowModel.getObject().getName())
{
@Override
protected void onEdit(AjaxRequestTarget target)
{
LOGGER.debug("Editing {}", rowModel.getObject());

//proceed to display another panel to edit the entity

}

@Override
protected void onDelete(AjaxRequestTarget target)
{
LOGGER.debug("Deleting {}", rowModel.getObject());

//proceed to delete the entity

}

});
}
});

//add other columns


//add the columns to a data table
