Refresh a Tree XML dataProvider

Hello!
I have a problem with refreshing a Tree dataProvider. This is what I use:
[Bindable]
private var xmlFontes: XML;
I then use it to put some php/sql generated xml. And then I make it a Tree dataProvider.
So far so good... But I need to refresh the xml, and I use xmlFontes.refresh; and it works great. But I need to know when the refresh is complete, and I can't. Is it possible?
Thank you so much for your help!
Alexandre

Well... I don't know if I can explain mutch better... My english is not great!
I'm using a SpringLoadedTree, that I believe is some kind of tree but with more functions.
When my application initializes it makes this:
<mx:HTTPService id="treeF" showBusyCursor="true" url="php/treeFontes.php" resultFormat="e4x" result="onResultFontes(event)" />
My treeFontes.php file queries a sql database and gives back some xml code. And then:
xmlFontes = XML(event.result);
And xmlFontes is the dataProvider of my tree. This tree I'm using lets me drag and drop items between the tree nodes. When I do that I call another HTTPService to update the node position on the database. When it finishes updating the database I call the <mx:HTTPService id="treeF"... again and it updates the tree.
What I wanted to do is this:
When I drag the node on the tree I save that nodes parent id and when I drop it I save the new parent node id - confusing. With this I was hopping to be able to open the tree nodes from where I dragged and droped the child node. I can do this, but only with the click of a button...
In my onResultFontes function I call another function that does what I want, but it's not working, beacause I don't know if it has finished generating the tree, and it probably tries to open the nodes before they are created.
The function to open the nodes previously opened does something like this:
expandParents(node[0]); - This is the original node - saved on drag
expandParents(node[1]); - This is the destination node - saved on drop
It's quite confusing... But I can't think of a better way.
Thanks and sorry for all the confusing explanation!

Dynamically refresh a Tree

Hi Everybody,
I need to get Tree nodes refreshed based on some criteria.
The criteria will be based on a combobox or PopupMenuButton change
event. To achieve the same, I am using a Tree control, which is
being populated by an XMLListCollection. The XMLListcollection has
a filterFunction that filters the tree nodes that will be
displayed. The criteria for the filterFunction depends on a
ComboBox selection.
The filterFunction for the XMLListCollection is called during
the Combo change event but the tree data is not refreshed and
doesnot display the desired filtered result.
I have tried doing this for a arraycollection with a datagrid
and it works fine but doesnot work for a tree. How can we refresh
the tree data. Below are the code snippet used to perform the Tree
filter which is not working and not throwing any error as well.

Please advise and suggest on where I am going wrong or if
there is any other better way to perform the desired result.
Thanks.

You can not filter but can you refresh the tree control? Or
do you have to build a new dataprovider every time ... What if you
want to add an item to a node such as:
tree.dataDescriptor.addChildAt(tree.selectedItem,
{label:"topper", children:[{label:"one"}, {label:"two"}]}, 0);
once you add the item you have to expand the node that you
added it to ... how do you get the tree to refresh ... i have tried
tree.validateDisplayList();
tree.validateNow();
treeDp.refresh();
and my dataprovider is an ArrayCollection

Problem of refreshing a tree in web dynpro java

hi all,
I'm facing a problem for refreshing a tree in web dynpro java for SAP HR.
I created a viewset with 2 cells( 1 view for each).
In the 1st view I created a droplistbyindex to select the unit ID and in the 2nd view ( defaut=false) I called a method to populate my tree according to my selection in the 1st view ( method called in wdInit).
When I make the first selection everything is ok.
But when I select another unit ID, the tree is not changed and I know the context is well changed according to my selection.
So I think the method is executed only the first the view is called.
In this case, how can I refresh my tree on real-time?
Thanks for your help

May be u can write the code wdDoModify instead.

Manual Drag and Drop from Tree to Tree with XML dataProvider

Been struggling with Drag-n-Drop between Tree controls. As far as I can tell, it doesn't work very well.
I have boiled it down to a minimal project below and would be ever so grateful if someone can tell me what I am doing wrong.
The complete MXML application file is below. Flex 3.5.
Two trees side-by-side. One has XML that I want to drag over to the drop tree.
On the DragOver() event, I select the node which is given to me by the calculateDropIndex() function.
After startup; first open the L1 branch on the left and drag L11 over and drop it on the right Tree.
Looks good, root node is selected/highlighted and dropFeedback is correct and dropping the node drops it as a child of "Start Here".
Open the Start Here root node to see it.
Now proceded to #1 below.
Here are the problems:
1) Drag "L12" from the left tree over to the middle of the right tree (below "L11" just dropped). "L11" will not be selected. The Selected node (with dropIndex=4) will be the entire new nested XML "<L><L11/></L>"; and therefore only "Start Here" node will be highlighted. Drop "L12" anyway. So, it is acting like selectedIndex = <anynumber> will only select the root node. How do I get the new L11 to show as a drop target?
2) Now drag "L21" from the left tree onto the right tree; again starting below all nodes on the right tree. Selected node will not change until you drag it above #2 out of 3. Then, you can drag it anywhere, and correctly highlight/select any node as the target, and get that node in code. This is a problem. Go ahead and drop it anywhere. Now if you drag, for example, L22 from the left it will correctly highlight/select any node without having to first drag above #2 in the list.
3) Now, grab and drag L11 a second time and drop it at the bottom on the right. Drag L23 over. No matter which L11 you hover over, it highlights the one at the bottom. How can this be right?
Those are the bugs I would like to figure out. If I am doing it wrong, I sure would like to know what I am doing wrong. The code below is distilled down to one simple mxml application module.
Thanks,
Jeff

I just found out that by setting the dataProvider for each tree to the XML variable instead of the XMLListCollection variable, problems #1 and #2 went away!
But the documentation says to use an XMLListCollection if you will be dynamically changing the tree contents.
And, I just found out that #1 returns if I specify showRoot="false". But with it set to "true" that problem goes away. Is there some sort of minimum XML required to make drag-n-drop work on these Tree controls?
Hmmmm. It appears that (for #3) the calculateDropIndex() will always return the last matching XML node - by name - in the tree.

Tree control and XML dataprovider

Hi,
I am trying to get this xml ( http://mitjafelicijan.net/test.xml ) working with my tree control in my Flex app and cannot figure it out how exactly to do this.
my Flex code is this
<mx:Tree left="0" top="0" bottom="0" showRoot="true" id="trvTreeview" right="0"></mx:Tree>
and my AS code is this
var tmp:XML = XML(event.target.data);
trvTreeview.dataProvider = tmp.node;
I get such output
http://mitjafelicijan.net/tree.png

The default data descriptor will see any child node as a child and claim that node is a folder. If the xml node used attributes like this:
Then there aren't any child nodes. However, if you can't change the XML structure you can create a custom TreeDataDescriptor that is smarter about hasChildren()

Expand all on tree when dataprovider is an object.

When I first start the application I would like to have the
tree and all nodes fully expanded. My RemoteService returns an
object that looks like the snippet below.
I have seen a lot of code on how to expand all nodes of a
tree, but I do not have a tree.selectedItem yet as I have just
created the app. I would like to add an expand all to the
creationComplete on the tree but I an not sure what to pass the
tree.expandItem. I have tried to pass tree.firstVisibleItem. I have
tried to iterate over the children of the root object of my
dataprovider. I can do it with xml but can't seem to figure it out
using an object. Any ideas?

I tested with your data structure and the following worked
for me. I called expandAll(myTree,true) on creationComplete and all
nodes were open on load.

Problems with codepage after refreshing data from XML

Hello,
I've created a dashboard with XML connection.
XML file with new data is created via macro in INPUT.xls Excel file. This INPUT.xls file was created through exporting spreadsheet from Xcelsius and then adding a macro to it, so text data should be this same codepade. Generated XML through macro have no errors and Flash file gets numeric data with no problems.
But there is other problem with text's codepage. After reload there are some unidentified symbols in place of polish alphabet letters.
What should I do to make it right? Is this a problem with codepage or something else?

Problem refreshing the Tree Component icons

Hello,
I'm using the Tree, adding the nodes dinamically, following the example: http://www.netbeans.org/kb/55/vwp-databasetree.html
This Tree shows the access permissions from the users, and show a red icon on the itens without permissions and a green icon on the itens with permissions.
In the nodes, I add an action that change this permissions when the user click.
If the permission is Ok on the clicked item, the action remove this permission and vice-versa.
The action is working fine, but the problem is the refresh of the tree after click. The icons stay like before the click. It is refreshed only if I navigate to another page and return after. Then the icons are showed correct.
In the method that add the nodes, I select the node icons like this:
if (havePermissionModulo(grupo, modulo)){
moduloNode.setImageURL(imgPermissaoOk);
}else{
moduloNode.setImageURL(imgPermissaoNegada);
Where imgPermissaoOk and imgPermissaoNegada have the path to the images.
Sorry by my english :)

It is hard to tell
When the user clicks on an icon, is the page submitted to the server and the page redisplaying itself?
Is the tree's clientSide property cleared (that is, false).
Is the browser caching the images? What if you hit a Shift-Reload?

Getting xml dataprovider to reload information on page load... not compilation.

Hey everyone,
I've got an app that grabs information from a XML file on my server. After the user has used the app, they'll have the option to save their input. I've got the application to edit the xml file and store the users' information. After saving the information, however, the XML datasource doesn't update the combobox that allows users to see passed saved saves. Here's how it's being done now:
This is the code to grab the XML file while I compile:
<mx:XML id="applicantsXML" xmlns="" source="http://www.hr.fsu.edu/SubSites/HRAPPS/salaryconsideration/applicants.xml"/>
Here's the combobox being populated with the XML information:
<mx:ComboBox id="applicant_combobox" y="35" x="135" dataProvider="{applicantsXML.app.appid}"></mx:ComboBox>
Is there any way to get the XML to repopulate using applicationComplete or something like that?
Thanks a bunch,
Brds

By "Store the users' information" i mean that the application uses sliders, checkboxes, and textboxes. After clicking the save button, these items will be saved into my DB and also put into an XML file. I've gotten all that part working... the problem is updating the XML as the dataprovider.
When you say "You can create a new dataprovider and reload the new XML file. Then point the combox to the new data provider" I'm not sure exactly what you're saying. Can you explain a little please?

XML - DOM tree - XML

I'm building an application that takes an xml file, turns it into a DOM tree, then the user selects different options from a database to manipulate the internal information gathered by the original XML file, the program is a process and at the end of the process the original XML file has been updated with new information, i need help with finding some code to take the DOM tree information displayed to the user and save back out as a new XML file. any help would be greatly appreciated.

You can use JDOM, Xerces XMLSerializer, or J2SE's Transformer. The first 2 are pretty simple. The 3rd isn't too hard. An example can be found in code sample 3 on http://java.sun.com/developer/technicalArticles/xml/JavaTechandXML_part3/.

Refresh JNDI tree when accessing from outside the container

Hello,
I wrote a tool (a simple main class) which runs a thread to simply check the DataSources stored in an Application Server's JNDI tree (to see, if they can be used by other tools).
The problem is: Once the thread is running, it always gets the same DataSource back, no matter if the DS's properties changed. Let me describe what happens:
1. I defined a DataSource in Orion 2.0.5's data-sources.xml
2. Testing it with an application in the container works fine.
3. I start my external tool, which gets the DataSource and checks it - it works
4. Then I stop the container and change the DataSource props in a way that the connection won't be established (i.e. wrong url)
5. After restarting the container, the aplication in the container throws the expected SQLException
6. But the external tool (which is still running) does its next lookup for the DataSource and gets a valid one and claims that everything is fine.
Well, it seems to me that the external tool outside of the container somehow gets a copy of the JNDI tree (or something) and does no real lookup, but I just don't know. Another hint is, that - unless I do a context.list(""); before looking up the object - the container did not even need to run after the first lookup from the external tool - it just needed one lookup and afterwards I could stop the container without having the external tool recognizing any changes. Well, it at least recognizes that now by the above mentioned context.list(""); ...
I hope I explained it right, let me just add some code of my tool.
Thank you in advance for any hints!
