Hi,
Can someone help me figure out what would be the cause why I am suddenly
getting the following error when I close one of my modal windows?
Cannot find behavior with id '0' on component
'org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow:srScreen'
in page '[Page class = ums.app.NewSalesReport, id = 2, render count = 3]'.
Perhaps the behavior did not properly implement getStatelessHint() and
returned 'true' to indicate that it is stateless instead of returning
'false' to indicate that it is stateful.
I have a class NewSalesReport where I add the modal window:
srScreen = new ModalWindow("srScreen");
srScreen.setTitle("Sales Report Preview");
srScreen.setInitialHeight(500);
srScreen.setInitialWidth(800);
srScreen.setResizable(false);
srScreen.setCssClassName(ModalWindow.CSS_CLASS_BLUE);
srScreen.setPageCreator(new ModalWindow.PageCreator(){
private static final long serialVersionUID = 1L;
public Page createPage(){
try {
srPreviewWindow = new SRPreviewWindow(srScreen,
shipmentID, grower.getDefaultModelObjectAsString());
}
catch (ClassNotFoundException e) {e.printStackTrace();}
catch (SQLException e) {e.printStackTrace();}
return srPreviewWindow;
} });
srScreen.setWindowClosedCallback(new ModalWindow.WindowClosedCallback()
{
public void onClose(AjaxRequestTarget target) {
try {
scp.setContainers(DbQueries.getGrowerUnreportedContainers(dataBase,
grower.getDefaultModelObjectAsString()));
target.add(scp);
}
catch (ClassNotFoundException e)
{e.printStackTrace();}
catch (SQLException e)
{e.printStackTrace();}
}
});
srScreen.setOutputMarkupId(true);
add(srScreen);
And the window itself SRPreviewWindow:
public SRPreviewWindow(final ModalWindow window, final int shipmentID, final
String grower) throws ClassNotFoundException, SQLException{
...
add(new AjaxLink("cancel"){
public void onClick(AjaxRequestTarget target) {
window.close(target);
}
});
