How to auto expand a tree2 & set focus?

[Adam <ad...@softfab.com>]

Dear All,

I am looking to use jsf to add a tree to allow people to insert std 
documentation into an object model expressed in an xml format.

basically you have some XML which is:


Class name="MyClass" /Attribute name="MyAttrib" /DataType name="MyDatatype"


In the schema I have created to cope with this, within each datatype you 
can have a number of different text elements (e.g. a boolean datatype 
would obviously have text for "false" & text for "true". Equally a given 
Class/Attrib/DataType might have different documentation dependent upon 
where it's being used/the sort of model it's being used.


So .....many text children of datatype each of which carries a "value" 
attrib so that I can drill right down to the right piece of 
documentation for a datatype with that value in that attrib in that class.

Onto my JSF question

I have created a JSF tree where the treemodel is based on a JDOM Dom (if 
anyone wants the code I can post it) which contains everything & my 
initial choice  (I am opening the tree in a popup/new window based on a 
link in another page) can give me the classname, Attrib name, datatype 
name etc right down to the value of the datatype.

What I want to be able to do is to unroll the tree to that point & set 
the focus to the lowest level I can find a match for (e.g. if there was 
no datatype value then just show me all the datatypes for that 
class/attrib but with the focus set to the element/node with that 
datatype name.


Any ideas/tips/hints?

TIA

Adam

Right, there is <af:tree> ([1]) and <af:treeTable> ([2]).

The public drop has a *compiled* web application demo,
which includes the adf-faces-api.jar and the adf-faces-impl.jar

Feel free to compile on your own against MyFaces' source code ([3]).

I'd start by looking at the code for tree2.  You will probably need
something like tree2 (or datable for that matter) that knows how to
render its own children.  You will also need a way to model the data
and the state of that data.

Coming soon will be a new TreeWalker interface.  That might help give
you some ideas as well.  Finally, I believe ADF has a tree as well. 
You can check that implementation.

Good Luck

Sean
