I complained the ajax modal window cannot show every time when i click the ajax
link ,after the updgading ,it can work well. but i get a new problem, I used a
modal winwo to input something, when i open the modal window first, it's ok,
but when i open it again , it will generate the bellow error. i searched the
form ,and find someone also happen the same error.
final DefaultDataTable table = new DefaultDataTable(listContainer, "dataList",
columns, dataProvider, 15);
table.setOutputMarkupId(true);
final ModalWindow modal1 = new ModalWindow(this, "modal_add");
modal1.setPageMapName("modal_add-1");
modal1.setPageCreator(new ModalWindow.PageCreator()
{
public Page createPage()
{
return new EditFilterWordPage(getPage(), "");
}
});
modal1.setWindowClosedCallback(new ModalWindow.WindowClosedCallback()
{
public void onClose(final AjaxRequestTarget target)
{
target.addComponent(table);
}
});
modal1.setCloseButtonCallback(new ModalWindow.CloseButtonCallback()
{
public boolean onCloseButtonClicked(final AjaxRequestTarget target)
{
target.addComponent(table);
return true;
}
});
new AjaxLink(this, "createRecord") {
public void onClick(AjaxRequestTarget target) {
modal1.show(target);
}
};
the second open generate the below errror
