How to persist parent and child tree node data through JSF and Hibernate

Dear dudes,
I'm a novice to JSF and Hibernate
Actually i want to create a tree structure where for each child node, i should have the parent node reference in my form and then when i save, i need to save the corresponding child node data in the database.
node-1
node 1-1
     node 1-11a
node 1-2
node-2
   node 2-1
   node2-2Whenever i click node 1-1 the corresponding parent node ( node-1) reference should appear in my form and when i save this data this data should be saved under parent node and the tree should be re-rendered.
How this can be accomplished and if there are any URL's please refer.

Recursive function to find the parents of a tree node

Hi,
I need help to write a recursive function to get the parents of a tree node upto the root.The major problem is , each node can have more than one parent.I have two methods ; one to get the immediate parents(getParents() will return me a vector) and the other to get the parents upto the root(will also return me a vector).
Thanks in advance,
nanduvs

let me risk a dumb response ..
if there are multiple parents
why not just follow the first parent
back to the root
if everything starts at one root

Just use a format like this:
http://<Server Name>:<port Number>/OpenDocument/opendoc/openDocument.jsp?sDocName=reportB&sType=wid&sRefresh=Y
&lsMObjectName=[test1],[test2]
Here in lsM[ObjectName] parameter [ObjectName] = the object name which you want to send data to ReportB
I can give you a idea of creating hyperlink for jumping another report (Here ReportB)
Just use a formula like that in any cell:
="<a href=http://<Server Name>:<port Number>/OpenDocument/opendoc/openDocument.jsp?sDocName=reportB&sType=wid&sRefresh=Y&lsMObjectName=[test1],[test2]&sWIndow=New> Click here to view </a>
Now from the property select Read cell content as "Hyperlink"...
thats it......
For more information please see the
"OpenDocument" artile
Hope you can get help from this

Display tree node data in bold characters

Hi,
I have a requirement where I need to display tree nodes data in bold characters. If I click on a particular tree node, next time it should appear in normal font only which means that some task had done using that tree node. Is my question clear??
Plz help me....
thanks,
ravindra.

Hi Ravindra,
I think it is possible, i have not done it but let me explain how we can do it.
In <htmlb:treeNode> tag there is an attribute 'text' in
which we specify title of that treeNode.
Now you define a page attribute 'treeNodeTitle' type
edpline and in onCreate assign it value <html><b>MyTreeNode</b></html>
When you click on this node then you do event handling
in onInputProcessing, there assign only 'MyTreeNode' to
treeNodeTitle.
sample code may look like this...
<htmlb:treeNode
id = 'treeNode1'
text = '<%=treeNodeTitle %>' >
</htmlb:treeNode>
Page Attribute
treeNodeTitle type edpline
in onCreate
treeNodeTitle = '<html><b>MyTreeNode</b></html>'
in onInputProcessing
in event-handling code for that treeNode write
treeNodeTitle = 'MyTreeNode'
I hope this will work.

Narinder Hartala

What does it tell you. If it says it isn't compatible, then you don't have a mid/late 2007 MBP. You might have an early 2007 MBP, which cannot run Mountain Lion or Mavericks.
You can check here to see exactly which MBP you have: http://support.apple.com/kb/ht4132
If you hold down the Option key and select System Profiler from the Apple Menu, it will display the model identifier under the Hardware Section.
It must be a macbookpro3,1 or later.

How to identify parent item & child (component) item??

Hi
Plz let me know how we can identify parent item & component item in the same bom?? I am checking it in table STPO but not able to identify.
Thnx
Neel

Hi,
I hope there is no such indicator to differeciate parent material and child material in same BOM.
i will explain one simple way to find out.
Suppose you are having three Material Number ex P1,C1,C2 .
Suppose ur having three Material Number ex P1,C1,C2 .
1.Use table MAST and give the Material List - It will give Parent Material list only(P1)
2.Give the BOM Number to table STPO - It will give child material list of Parent Material BOM(C1,C2) with repect to BOM
3. Use report CS15 to find out that Parent Material (P1 Material from MAST) material is being used as component in Some other BOM.

Af:tree - how do I highlight the selected tree node?

af:tree
I checked the generated CSS file. I found that when a tree node is selected, the related CSS attribute is:
.xj:link{
font-family:Arial,Helvetica,Geneva,sans-serif;
font-size:10pt;
font-weight:normal;
color:#663300
I created a customized CSS attribute, but then all of the links have the customized CSS attributes.
How do I just highlight the selected tree node link?
Thanks,
--Todd

try doing the onclick javascript method
you have to place it on the node element and id must be made dynamic
for this use 'this.id'
by which the current id of the node is passed
and by capturing the id name in a var
use the same for invoking its selected property and make it true
like this
var currentid = this.id;
this.form.currentid.selected = true;

How to hide default tooltip for tree nodes?

I have an af:tree.
When a node contains a long string, the tree automatically creates a horizontal scroll bar to accomodate it.
But when I hover my mouse on top of the node, a tooltip is coming showing the complete text of the node.
Because of this I cannot drag and drop this node.
Is there anyway to hide this?

Still can't get rid of the tooltip the layout is:
<af:panelStretchLayout>
    <f:facet name="center">
        <af:panelSplitter>
            <f:facet name="first">
               <af:panelAccordion>
                   <af:showDetailItem stretchChildren="first">
                       <af:tree>
                       </af:tree>
                   </af:showDetailItem>
               </af:panelAccordion>
            </f:facet>
        </af:panelSplitter>
    </f:facet>
</af:panelStretchlayout>Which should be pretty fine in terms of geometry management.
If I move the splitter too much to the left the whole label can not be displayed => a tooptip pops, which prevents the node from being clicked.
Maybe the lables have to wrap in some way instead of stay 'under' the splitter.
Same behaviour with or without af:panelCollection wrapping the af:tree.

JTree and selected tree node

I am allowing the user to search for a node in a JTree. I can find the node and progamatically expand and select the node. What I would like to do next is find the x,y coordinates of this selected node so I can use Robot to move the mouse to this node. I have hover help which is chock full of information in HTML describing this node, however, the user now is required to move the cursor to this selected node to see the hover help.
Any help would be appreciated.

Hi ,
