Cannot find element with id "gwt-uid-". Perhaps it is not attached to the document body.

Hello everyone,

I am fairly new to Google Web Toolkit, but I love the Polymer&GWT combination. Now I wanted to add widgets to a container. I couldn't figure out what was wrong because it kept giving shitty umbrellaexceptions: "Cannot find element with id "gwt-uid-<n>". Perhaps it is not attached to the document body."

Could anyone possible help me?

Container:

<c:ServerList ui:field="serverList">
</c:ServerList>

Function to add server:

@UiHandler("addServerButton") /*This is a PaperFab button fyi*/
public void onAddServerButtonClick(ClickEvent event){
serverList.addServer();
}

Function in ServerList class

public void addServer(){
root.add(new Server());
}
