Struggling with RichFaces tree and Ajax. I don't want to load whole tree only the necessary children
posted 4 years ago
I'm trying to build a heirarchical tree using RichFaces 3.3.3. The data that the tree will be built from varies greatly. It could be a large tree or it could be small; therefore, I want to go fetch the children when a node is expanded using ajax. I do not want to have to load all of the data when building the tree for the first time. When the user expands a node, I want to hit the database and bring back it's children at runtime
I have looked on the richfaces site, and have found nothing similar to what I'm trying to accompish. The examples I found are loading the entire tree up front.
Can anyone point me in the right direction? Sample code would be great. Thanks in advance.
Look again. Specifically, look at the actual RichFaces manual. Admittedly it can be confusing, but it's there. Fortunately. I had a system that would have otherwise downloaded over 3MB worth of menus every time the page was refreshed.
