AjaxFallbackLink - target NULL
Hello,
I tried to switch to Wicket 7 and I got a problem with all
AjaxFallBackLinks having target = NULL.
link = new AjaxFallbackLink<String>("tableImportRows") {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
log.debug("import new entries ...");
ModalPanel importPanel = page.getImportPanel(modalImport.getContentId(),
modalImport);
modalImport.setTitle(new StringResourceModel(
"titleImport", importPanel, new Model<String>()).getString());
modalImport.setContent(importPanel);
if (target != null) {
target.focusComponent(importPanel.getFocusComp());
modalImport.show(target);
}
}
};
Any help will be appreciated.
Thanks, Peter

https://issues.apache.org/jira/browse/WICKET-5953 could be related.
But it is about touch devices with IE11.

Re: AjaxFallbackLink - target NULL
Posted by Martin Grigorov <mg...@apache.org>.
Once you prepare a quickstart app we will be able to debug it and help you.
In the meantime think why you use AjaxFallbackLink in this use case and why
there is no check for target==null?
As you probably know AjaxFallbackLink is designed for cases when JS is
disabled in the browser, so your app works both with and without JS.
Apparently your app is not quite prepared for the "without JS" case.
