Please help i am struck here.
Hi there,
This is normal, you rely on the @NotifyChange but actually your object is already notified before the actual delete is happend cause you use the EventListener.
solution :
hdr.delete(true);
galleryList= new GalleryUploadServiceImpl().getImageuploadsList("");
BindUtils.postNotifyChange(null,null,className.this,"galleryList");
BindUtils.postNotifyChange(null,null,className.this,"showLineGrid");
}else if(Messagebox.ON_CANCEL.equals(e.getName())){
//Cancel is clicked
}
Greetz chill.
thank you for reply,
Still no refresh on grid, I am added this class,see once
hdr.delete(true); galleryList= new GalleryUploadServiceImpl().getImageuploadsList(""); BindUtils.postNotifyChange(null, null,img, "galleryList"); BindUtils.postNotifyChange(null,null,img,"showLineGrid");
}else if(Messagebox.ON_CANCEL.equals(e.getName())){
//Cancel is clicked
}
may be it help:BindUtils.postNotifyChange(null,null,img,"*");
Oke possible that that won't work.
What definitly works is this :
hdr.delete(true);
galleryList= new GalleryUploadServiceImpl().getImageuploadsList("");
BindUtils.postGlobalCommand(null, null, "refresh", null);
} else if(Messagebox.ON_CANCEL.equals(e.getName())){
//Cancel is clicked
}
and you make a new method :
@GlobalCommand
@NotifyChange({"galleryList","showLineGrid"})
public void refresh(){}
