Navigating from a tree.

Hi,
I do have a tree as described below in my application...
<mx:XMLList id="treeData">
<node label="Mail Box">
<node label="Home"/>
<node label="Student">
<node label="Create"/>
<node label="Edit"/>
<node label="View"/>
</node>
<node label="Professor">
<node label="Create"/>
<node label="Edit"/>
<node label="View"/>
</node>
</node>
</mx:XMLList>
Now how do i navigate to the various files from here, on the
click of the individual tree nodes. What are the containers i may
have to use to make this working.
Thanks in Advance.

Hmm,
I had a look at your example application on the supplied link, however I cannot find any instructions or steps on how to go about implementing this method.
Using my current method (from the thread linked in the first post of this thread) I have no problem getting the javascript to recognise changes and prompt the user on trying to leave - it's just that the href continues regardless of the user clicking cancel (wish grahamr managed to resolve somehow). Do you know why this might be?
My javascript (2 posts above) is fired within the Anchor tag of my tabs and tree items like so; (Im only using [ ] brackets here so that it will display in the forum)
[a onclick="javascript:checkForChangedData();" href="#TAB_LINK#" ][font color="#FFFFFF"]#TAB_LABEL#[font][a]
Or if possible is there any assistance you could provide for implementing the method in your sample application? (I dowloaded the app but that page was not in it)
Any help you can provide is greatly appreciated,
Jordan

Why custom layout not take effect if navigating from left tree

Hi,
I specified a custom layout for a repository in KM Content. The layout is a duplicate of AdminExplorer, which contains a tree structure in the left panel.
The problem is, when I navigate the repository in the right panel, the custom layout is always in effect. However, if I navigate from the tree structure in the left panel, the custom layout doesn't take effect.
Anyone knows why? I wonder if I forget to configure something, or this is indeed not supported?
I don't know how to attach screenshot - if you wanna see the screenshot for more info, please add [email protected]
Thanks,

problem doesn't exist. close it.

Issue with creation of ADF Table from ADF Tree selection

Hi,
Following is the usecase.
I've created ParentVO & ChildVO from a single table with view criteria to filter the nodes.And then created two View links ParentToChild & ChildToChild.
Added VOs & corresponding ViewLinks to ApplicationModule. It's got created hierarchy as Parent1->Child1->Chiled2 in Data model section of AM.So Iam done with tree creation process in Model.
As VC can't be applied for sub levels. In order to set the VCs for sublevels, followed the below approach.
Created a bind variable for tree. I've set the VC for both parent & child VOs in managed bean before setting the tree variable in setTree method. So now Iam able to display the required tree in UI with applying VCs.
Now , I can select the required nodes from tree and then click on command button to display the selection list as a table.
In order to achieve this, I tried below two options.
1) Created separate Child VO instance (Child3) from Child VO and applied same view which applied initially. and the dragged the Child3 from Datacontrol to UI(jsff) as a table. When I run the application,it's displaying all the records from the DB table without applying VCs.
2) Dragged the Child2 as a table on UI. When I run the application, it's displaying first record from the table without applying VC.
But no luck in getting the required functionality.
I've Following queries.
a) If we update any transient attribute value for an VO instance, will it effect at VO level or only for that particular instance?
Why because, I've created new instance of same VO. But the changes are not effecting for transient attributes in the new instance of VO.
b) Can some one suggest on my usecase to display the selected nodes from a tree in table format?
I tried my level best to explain the usecase. But let me know,if you have any queries on my usecase.
Thanks in advance,
Samba.

How do i Drag and drop From one tree to another and vise versa?

Yes, I have set dragEnabled and dropEnabled to true. I trying to put restriction on dropping the node(aka leaf) of 1st free tree inside the branch(aka folder) of the 2nd tree. If something is dragged from tree1, it should be dropped only on tree2 i.e., dragged node should be appended at the end of tree2 and not inside nay of the branches of tree2. This functionality should work on both the trees. I'll be glad if u can provide the solution.

Copying data from a tree to another

Hi all!
I am in a trouble when I try to copy somedata from one tree to another one.
The interface allows the user to select one item from the first tree, and then when he clicks on a button, this item is copied to the second tree. The first tree stays in the same way. It is not permitted to the user to do any operation on the first tree.
It is permitted to the user to remove items from the second tree. But I implemented this without any trouble.
The problem occurs, after I selected the item that will be copied. Then, when I click on Add button, an unexpected error occurs.
The vi is attached.
Thank you in advance

Error with getAttribute( ) function, while navigating from parent to child

Hi,
I have been trying to develop a small project with two task flow(TF).
Both the TF contains only one page.
Both of my pages are made from different VO,s.
from the Parent page (P1) if i select a row and navigate to Child Page (P2), i need to filter the result in P2 using the selected row in P1.
From P1 when i selected a row and navigate to P2 by clicking a button, i have used a Bean to get the parameters from the selected row and Passed the same to TF2.
I made an AMImpl method and binded it to P2, such that whenever my P2 render this AMImpl method will be executed.
Inside the AMImpl method i am trying to run the VO query of P2 with new selected criteria from TF1 ie.P1.
i also have few more functionalites in P2 like when i select a row and clicks on a button i will some some info on a pop-up for the corresponding selected row.
When i run the page P2 individually,all works fine. But when i navigate from P1 to P2 none of the functions are working, i.e when i click on the button on P2 to see popup its showing that Attribute is Null in the selected row, even though the attribute is not null. After navigation in P2 this function getAttribute( ) is returning null. but when i run P2 individually the same function is returning all required fields without error.
Actual AMimpl.java method code :
RowKeySet selectedRows =
Table.getSelectedRowKeys(); //Table is a "Rich Table" i declared outside the method and binded to my actual table on P2
Iterator selectedRowsIterator =
selectedRows.iterator();
DCBindingContainer dc =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBinding =
dc.findIteratorBinding("P2Iterator");
RowSetIterator rowSetIterator = iterBinding.getRowSetIterator();
Key selectedRowkey =
(Key)((List)(selectedRowsIterator.next())).get(0);
Row selectedRow = rowSetIterator.getRow(selectedRowkey);
String parameter1ForCurrentRow =
selectedRow.getAttribute("parameter1").toString(); // -->this particular line is returning null while navigating from P1 to P2, but the same line returns actual value if the run P2 individually
Kindly guide me how to achieve this.
Regards
Siva

Hi Timo
thanks for your reply.
The reason I am doing this is to avoid the numerous instances of VO2 (Child VO) that will get created for every row of VO1. (eg: 100 rows of Vo1 means 100 instances of VO2 created & executed ).
I am trying to avoid that by Binding and executing the params to a single child VO instance, only on the click of a button.
Please advise if my assumption about as many child instances of VO2 being created and executed is incorrect and ADFBC does some kind of Lazy instantiation / loading of the child VO until the point of execution of the UI code where it is bound to ?

Passing non-key field values to a form from a tree link

I'd like to be able to link to a record form from a tree, and to pre-populate certain fields in the form from values available in the tree, even if there isn't a record matching the primary key value on the tree.
I hope that makes sense.
Let me fill in some more detail. I have dummy nodes in the tree, which don't correspond to data items, but to types of data items ( underneath which I have the real items ). I've made the dummy nodes a link to the form in the same way as the real items, so that when you click on the dummynode, you go to the form ( which is blank) and can create a new record. I'd like to populate the form with as much information as possible when this happens. I've tried adding the fieldname/formvalue to the link string but with no effect.
Thanks, Mark.
If the forum allowed screenshots to be posted I could show you what I'm trying to achieve.

If your form items are of source database column, than it will not work. However, you may create a custom form and have no source for the items. For that, you will need to create a custom procedure to fetch, update and delete the records.
If I understood your question properly...

Blank Screen while navigating from one screen to another in a web applicati

Blank Screen while navigating from one screen to another in a web application.
While navigating through the screens of the web-based application, I get blank screen at times. The application menu bar is still visible and the header and footer jsps are also still available. The main processing frame alone goes blank. Once I get the blank screen, I am able to choose from the menu option and contine navigating through the screens.
The application has been deployed on WebSphere Application Server v6.0 and uses JDK 1.4.2. I have checked the application, server and systemerr logs. And there are no exceptions in any of the log files. There is no difference in the logs for a normal flow and the flow when the blank screen occurs.
The blank screen does not occur always. It occurs around 3 out of 10 times. If you consider a particular page, mostly it loads normally and very few times, the blank screen occurs.
Compression filter is being used and it gets invoked for every request. Size before and after compression also gets printed in the logs.
Could this be causing any issue in terms of memory handled or could any jsp timeout be happening, though there are no exceptions in the logs.

Well, since no one has any ideas, here is my two cents worth:
Can you turn off compression and see if the problem goes away? If not, I suggest creating a small separate project with the same functionality as that part of the program that causes problems and see if you can duplicate it. Use System.out.println() in the java code and out.write() in the JSP pages throughout the java and JSP code to write to the log file or console as each section is run to see what section is causing problems. You can also consider commenting out sections of code in your JSP page to see if you can isolate the problem.
I had a similar problem with the screen being blank and this is what I found:
My JSP page had an include tag in it that included another JSP page. The outer JSP page was drawn and waited for the included JSP page to be drawn. The logic took several minutes to run and something timed out. The inner JSP page was never drawn. No log entry occurred. It appears that it was not Apache or Tomcat that caused the problem, but some firewall or similiar such device. If you have a firewall or similar device, see if the person who maintains it can temporarily set its timeout to a very long time (15 minutes) to see if the problem goes away. Apache and Tomcat probably also have a timeout feature too. You will have to read up on their configuration settings on how to set them.
By the way, each of those devices probably has its own log file you can read to see if its reporting an error.

I created ADF unbounded taskflow and want to use it in my webcenter portal application for navigation from one page say Page x to another say Page y by clicking on the hyperlink in the Page x. How to do this in webcenter portal application. When I try to add the taskflow in the navigation model it is taking to the blank page instead of taking to Page x. Many thanks in advance.

Problem in navigating from one report to another in OBIEE 10g

Hi,
I am facing an issue with OBIEE 10g while applying navigation on my reports.
Lets suppose I made a report showing list of all items(in broad categories) sold on a particular day, say Dairy, Frozen Foods, Chocolates etc.In this report there is a date prompt showing the date of sale.
Now there are certain items that are distributed within these categories, like dairy includes milk, cheese, butter etc.
Hence, my navigation should be like when I click on a particular item category, the control should move on to the report which has all items under that particular category and the prompt for this report should show the same date as passed in the previous report.
But sometimes what happens is that on clicking the navigation from first report to the second one, the date is not persisting in the prompt. I say sometimes because at times the navigation does work correctly. This is a bug of Obiee or something which is giving unexpected results.
Kindly help with your suggestions.
Thanks
Ankita

Ankita,
This is not a bug in OBIEE...I'm sure something is missing. If this is working for some cases and not working for some other case then you will need to find the root cause. Try in bits and pieces...Step by Step with some dates (unit testing). Ideally this shud work properly.
For an instance try with OBIEE drilldown feature and not with navigation with a single sale date and observe the behavior.
Hope its clear...

Popups: Navigation from view to window does not work

Hi,
I open a second window as popup. This window has 2 views embedded, displaying view1 first. On some actions I would like to navigate to view2.
Defining an outbound plug on view1 and an inbound plug on view2, connecting them and firing the outbound withith the onaction works absolutely fine.
However, for some reasons I would like to avoid a direct navigation, but would like to navigate from view1 to the popupo window and from there to view2 (or maybe another view, ofcourse also embedded in the same popup window). Unfortunately I fail on this scenario - I can fire the view-to-window plug, but the destination on the window side (handle in method) is never reached.
Since the same concept works fine on non-popup windows I wonder whether a navigation from view to embedded window does not work for popups?
Any idea?

Hi Yashpal,
no, just one window.
The first link is view1 -> window, the second window -> view2.
I.e., I fire in the view the outbound plug, which is connected with its window.
In the window I fire an outbound plug, which is connected to view2.
In theory this should work - for non-popup windows I do not have any problem at all, however, for popup windows the navigation from view1 to the window is not processed.
In the meantime I played a little bit further: Instead of firing a navigation from view1, I now fire an event defined in the component contoller, on which an event method is registered within the window. Doing so, I reach the window, which I didn't reach via the navigation link. Once in the window, firing to view2 works just fine ...
Hope the issue is a bit clearer now. Also I found a solution, I am surprised that the simpler way via navigation does not work.
