gwt2 - With GWT, is there a way to not load widgets declared in uibinder xml files? -


one common design have gwt create widget contains 2 children: , b.

i declare these 2 widgets , b in uibinder file associated main widget.

what want load or not widget depending on if statement.

ideal approach set provided=true widget , set widget null when want not load widget. gwt throws error.

is there way declare widgets in uibinder , not loading them ?

thanks

edit: after lot of discussions, ideal approach declared field "provided=true" , "optional=true" when optional=true, createandbindui must not throw exception if field null. clean approach.

if think feature must exists in gwt, please star issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=5699

edit 2 : using lazypanel described thomas seems better way handle this.

i stumbled on gwt issue, led me here, here's take on it, 20 months later.

use lazypanel , set visible="false" it's content not built until need (simply call setvisible(true) reveal it, triggerring lazy-initialization of content.

lazypanel integrated uibinder declare content in same uibinder template, if simplepanel, without bothering creating subclass of lazypanel. see https://developers.google.com/web-toolkit/doc/2.4/devguideuibinder#lazy
