Re: Calling method for getting tree2 data

[Rob Decker]

I think if you look at it you really don't want it to be a business method. There is nothing business particular about it. It's not like you can fetch specific data. You get back a TreeNode which may or may not be the data in question. It may only be part of it, or can be none of it at all. Maybe you want to say fetchTreeA, fetchTreeB, or load data from a db. But you should hide that behind the getChildren method of TreeNode.   Then you can just return a TreeNode for the value binding method with a hidden root and depending on the Tree selected by the user getChildren returns treeA or treeB or data from the database if there is any. It's particularly useful to do it this way so you don't load data from the database you aren't displaying.     ----- Original Message ----- From: Mihir Solanki To: 'Rob Decker' Sent: Friday, April 15, 2005 7:59 AM Subject: RE: Calling method for getting tree2 data See if I simply write Cabinet.treeData, then I think its being treated as Bean�s property. I don�t want to have it.   I wanted to treat this method as a business method.   Thanks Mihir   -----Original Message----- From: Rob Decker [mailto:[EMAIL PROTECTED] Sent: Friday, April 15, 2005 5:21 PM To: MyFaces Discussion; [EMAIL PROTECTED] Subject: Re: Calling method for getting tree2 data   The tree2 value  expects a TreeNode object returned by the value binding. If you mean call, the method is CabinetTree.fetchTreeData not cabinetTree.getFectchTreeData probably not as you have to live with bean limitations specification. Why can't you just call it getTreeData? Then you can call CabinetTree.fetchTreeData from that method. ----- Original Message ----- From: Mihir Solanki To: 'MyFaces Discussion' Sent: Friday, April 15, 2005 5:06 AM Subject: Calling method for getting tree2 data   Hi,   I would like to know whether I can call a method (NOT PROPERTY) of a bean to get the data for the tree2 node.   If yes then could anyone guide me how?   <x:tree2 value="#{CabinetTree.fetchTreeData}" id="cabinet-tree" var="node" varNodeToggler="t" clientSideToggle="false">               :             :             : </x:tree2>   In the above �fetchTreeData� is a method which gets data from the DB and returns it.   By doing this I am getting some Invalid _expression_ error. So, is there any other way to do so?   Mihir Patni Computer Systems Ltd. Tel : 91 79 23240905 Ext : 413   http://www.patni.com World-Wide Partnerships.
