Hello Chen,
if you add the menuitem to the menu's floatinglist, it'll work:
var item1 = new lz.mymenuitem(*mm.flist*, {text:"Item 1"}, []);
Cheers,

Hi There,
In my application, I like to be able to create menus dynamically through the 'new' operator. As can be seen from the following code, the same constructs, if created using tags, everything works perfectly. But for the same thing, using 'new' will mess up.
In general, I have the feeling that using tags is more reliable than using 'new'. I understand the advantages of being declarative. But occasionally, we may be forced to resort the 'new' way instead of the 'tag' way. My understanding is that the tag-way is just a convenience. Eventually (deep inside the implementation), it will eventually use the 'new'-way to create objects. Not sure whether this understanding is correct.
Thanks!
Chen Ding

Below are the error messages I got when pressing the button:
