The following workaround works but violates encapsulation. Why doesn't
AjaxRequestTarget.AjaxHeaderResponse class escape special XML
characters?
public void renderHead(IHeaderResponse response) {
String scriptToRender = "<script>if (1 == 1 && true)
alert('Hello!')</script>";
if (scriptToRender != null) {
if (AjaxRequestTarget.get() != null) {
scriptToRender = scriptToRender.replace("&", "&");
// todo: escape other XML special characters
}
response.renderString(scriptToRender);
}
}
Thanks,
Alec
