All,

First, thanks for the huge support database out here.

I am using the zk tree component and have customized the code in the person tree example at http://www.zkoss.org/smalltalks/zkTreeModel/. My tree (with checkboxes) is loaded with live data and has the following structure

Grandparent
--Parent 1
----Child 1.1
----Child 1.2
--Parent 2
----Child 2.1
----Child 2.2

The Grandparent node is a static node (just one node whose value is populated in code) and the subsequent nodes are loaded with live data.

The problem I am facing is that when the data loads initially, only the children of Parent 1 are being loaded and not those of Parent 2. The children of Parent 2 get loaded only when I click the + mark beside Parent 2 after which the render method will be called again. To understand what's going on, I added another grand parent node and then noticed that Parent 1 and Parent 2 are both loaded initially. Basically, if there are N grandparents, N parents under each grandparent will be loaded in the first go without having to call the render method again.

This is probably an offshoot of the load-on-demand feature discussed in the smalltalk I pasted above. But I do not want that to happen. My data is not huge and I will not have performance issues, so I want all the parents and their children to be loaded in the first go. ZK documentation states that if the "fulfill" attribute is not specified for a component, all of its data will be loaded in the first go, but it doesn't seem to happen in this case. Can you please suggest if there is any solution to this problem?

I will post the code if required. Thank you very much,

S
