Change image on expand/contract of tree table node.

I have a tree table. If the branch node is expanded show an image of open folder. If the branch node is closed, then show an image of closed folder.
How can we know whether the node is expanded or collapsed ?
Any help appreciated !!

Thanks Umesh for the reply.
The implementation works well with non-recursive tree.
My Tree Table is a recursive tree.
When I try to implement the functionality, the problem I am facing is as follows:
Only the top level node is refreshed to display the new image. whereas the the child nodes do not get refreshed.
When i provide with a sysout in the managed bean, the child nodes, transient attribute displays updated value .
Could you please provide help regarding dis ?

Tree Table is not getting refreshed properly in Jdev 11.1.2.0

Hi,
I am seeing a peculiar issue with tree table not getting refreshed in Jdev 11.1.2.0.
Let me explain you my use case.
I have a tree table in a page, where the first column is displayed as selectBooleanRadio component. When user selects this selectBooleanRadio component, that treetable node should get expanded and at the same time all the child records(I have a select boolean check box component(transient attribute) at the child level) for that node should get selected. This is to allow user to unselect the child records, which he/she does not want to process further(some functionality).
Now when the user selects any radio button, the tree table node is not expanded, but the arrow beside the radio button for that node can be seen as expanded.
I thought it may be a partial trigger issue, so i tried refreshing the tree table programatically as well. But it was of no use.
Then I set the partial triggers wrt to SelectBooleanRadio component on the parent container of the TreeTable. After which somehow the node got expanded but the tree table shrinks in width and the actual disclosure functionality of a tree table is lost.
The same use case works perfectly fine in Jdev 11.1.1.5.
For reference:
I created a sample test case(Dept/Emp) in jdev version 11.1.1.5, which works fine. Workspace: http://adf-use-cases.googlecode.com/files/TreeTable1.rar
But the same test case, when i created in jdev version 11.1.2.0, gives issues. Workspace: http://adf-use-cases.googlecode.com/files/TreeTableUseCase.rar
If you download the application and run in respective jdev version, you will get to know more about the issue.
Please let me know, If I am doing anything wrong in the implementation of this use case.
Any help/suggestions are appreciated.
Thanks
Umesh
Note: My complete application is in Jdev 11.1.2.0, so I can't degrade my jdev version to 11.1.1.5.

Thanks Frank for the reply.
But upgrading the jdeveloper to 11.1.2.2 is not an ideal solution for us now, because of the size of the project.
Some how, the issue of refreshing the tree table is resolved. I am using a command button with clientComponent to true and causing a full page refresh.
I am not sure, if this is a perfect solution.
As you said, that this behavior may be an issue with the Jdev version 11.1.2.0, I am using. I am going with the above said approach.

ADF Tree table is not exapanding

Hi all,
I have to implement an ADF tree table along with a form. I have three Views,
two of the views are used to populate the Tree table, And one of the view used in the Tree population is used to manipualte the form,
And the third one is to populate a table. And I have a Popup call button in the same panelCollection where the tree table is placed
I am facing two issues with the the tree table.
1. The tree table is not expanding, if I click on the '+' on the node it won't expand and it will show me small circle which is trying to open the node.
But if I click on the Popup button and cancel(RollBack) the popup and come to the node, it will exapand. I don't kow why it is....
2. As I said I have a Form and I have to populate the form based on the selection in the tree table nodes, the form filed is same as that of the view used to populate the Tree table view.
But when i click on the tree table nodes it is not chaning the record according to the selection in the tree nodes. But in a master Detail form it is working fine. It is always pointing to the first record.
Please help.....

No vinod, I am not getting any kind of exceptions..
And mY tree table is
<af:treeTable value="#{bindings.TestVO.treeModel}"
var="node"

Tree table is not reflecting the updated model data changes at the front end

I have two tables ,
1) Provider table(tree table) 2)member table
I have implemented drag and drop functionality using jQuery UI on both tables.
In my scenario when I drag a member from the member table and drop it on the Provider table and also when I delete an assigned member from the provider table I will update the data fetched from odata model and again I will call the method which binds the data to the provider table so that the table will reflect the changes.
here is the code,
on drop:
$("#Provider tbody tr").droppable({
drop: function(event){
oController.AssignMember(oProviderId, oMemberId)
}).disableSelection();
Assign member function: here am updating the model.
AssignMember : function(oProviderId, oMemberId){
var oModel = new sap.ui.model.odata.ODataModel("../../../services/provider.xsodata/", true);
var oParameters = {};
oParameters.PROVIDER_ID = oProviderId;
oParameters.MEMBER_ID = oMemberId;
oParameters.CREATED_ON = new Date();
oModel.setHeaders({"content-type" : "application/json;charset=utf-8"});
oModel.create( "/PROVIDERMEMBERS", oParameters, null, function() {
var oController = sap.ui.controller("adsm.provider.member_assignment_view");
oController.GetProviderData();
},function(jqXHR) {
var errorMessage = jqXHR.response.body;
var jsondata = JSON.parse(errorMessage);
sap.ui.commons.MessageBox.alert(jsondata.error.message.value);
GetProviderData function: here i bind the data to the table
GetProviderData: function(){
var oModel = new sap.ui.model.odata.ODataModel("../../../services/provider.xsodata/", true);
var Context = "/PROVIDERS?expand=ASSIGNEDMEMBERS&$select=NAME,ID,ASSIGNEDMEMBERS/NAME,ASSIGNEDMEMBERS/ID,ASSIGNEDMEMBERS/PROVIDER_ID";
var oTable = sap.ui.getCore().byId("tblProviders");
oModel.read(Context, null, null, true, onSuccess, onError);
function onSuccess(oEventdata){
var outputJson = {};
var p = 0;
var r = {};
if (oEventdata) {
r = oEventdata;
try {
if (oEventdata.d){
r = oEventdata.d;
} catch(e){
//alert('oEventdata.d failed');
try {
if (oEventdata.d.results){
r = oEventdata.d.results;
} catch(e){
//alert('oEventdata.d.results failed');
try {
if (oEventdata.results){
r = oEventdata.results;
} catch(e){
//alert('oEventdata.results failed');
$.each(r, function(i, j) {
outputJson[p] = {};
outputJson[p]["NAME"] = j.NAME;
outputJson[p]["ID"] = j.ID;
outputJson[p]["PROVIDER_ID"] = j.ID;
outputJson[p]["DELETE"] = 0;
var m = 0;
if (j.ASSIGNEDMEMBERS.results.length > 0) {
$.each(j.ASSIGNEDMEMBERS.results, function(a,b) {
outputJson[p][m] = { NAME: b.NAME,
ID : b.ID,
PROVIDER_ID: b.PROVIDER_ID,
DELETE: 1};
m++;
p++;
var oModel = new sap.ui.model.json.JSONModel();
oModel.setData(outputJson);
oTable.setModel(oModel);
function onError(oEvent){
console.log("Error on Provider Members");
oTable.bindRows({
path:"/"
Its working fine in chrome but in IE the model data gets updated but the table is not reflecting the changes at front end.Can anyone suggest me a possible solution to fix this?
Please have a look at the attached screen shots.

How to remove Expand All in view menu of tree table

Hi,
I want to remove Expand All in view menu of tree table. How to do that?
Regards,
Raghu.

I am having the exact same problem.
However, I believe that displaying large amount of data via a tree table is fine as the user is able to quickly drill in to the data of interest.
It is just that the 'Expand All' option (as implemented) does not make sense in my case.
Given that I cannot hide it, is there an easy way to change it's behavior so that it does nothing (or provide an 'No implemented' alert).
I don't have the time/experience to implement custom menu items.
Thanks

Tree expand / contract not working when region copied...

Hi
I have a tree view region which I want to appear on each relevant page. Simple, thinks I, I'll copy the region from page to page... but when I do this then the expand / contract buttons don't work. If I create a new tree region then paste in the code from the tree region I want to copy all works well...
Using Apex version 4.0.0.00.46.
Anybody else seen this?

>
The existing page zero appears at the top of other pages, containing specific data. This Tree element only appears on the config pages and is on the left hand side of the page.
>
You've just caused me to make a discovery that I hadn't noticed in nearly 6 years of APEX use: Page Zero is assigned a page template! I've no idea why this is: I don't think it should; this template will have absolutely no effect on how the application is actually rendered so I therefore think we should ignore it and maybe it will go away...
Has the presence of a page template on Page Zero influenced your thinking on its use?
Understand that regions on Page Zero will not be rendered according to the Page Zero template, but according to the page template for the page they are included on. The region Display Points remain constant: if you assign the Tree element to region position 2 on Page Zero, and it's included on pages 6, 7 and 8, then it will appear in region position 2 on pages 6, 7 and 8. However, using page templates and CSS, region position 2 can be in completely different places on the screen on pages 6, 7 and 8 (and even be in different positions on the screen and on a printout from the same page...).
The other main thing about Page Zero is that the rendering of regions can be controlled conditionally, often using the Current page in Expression 1 condition, where a list of page numbers specifies which pages a region should be included on. So to make your Tree region only appear on Config pages 6, 7 and 8, set its Display Position to Region Position 2, and give it a Current page in Expression 1 condition with Expression 1 set to <tt>6,7,8</tt>. If the "existing page zero" elements appear on every page except 6, 7 and 8 then use the opposite Current Page not in Expression 1 condition...
Only very simple apps would tend to include all Page Zero regions on other pages in their entirety: most of the time there will be mix'n'match using conditional rendering.
>
Which raises yet another question (getting my 2 cents worth here!) - can we conditionally change the position of a region? eg if on app pages 1 thru 5 then page zero is at top. if on pages 6 thru 8 then appears on left side?
>
Hope I've managed to explain why that's not how it works?
(And reflecting on the mysterious presence of a template on Page Zero, I can only think that it has something to do with the Display Point preview pop-up, even though it's entirely useless as a safe guide to where the region will ultimately appear...)

How to achieve this tree table ?
My client wants that they should also be able to manage budge at Location or region level not only at the leaf(Dept) level.
I did a lot of research and finally found out that the details can only printed at the leaf(Dept) level.......
We can not hard code Region, locations and departments in table rows. When table tree is displayed we will only show all the regions... (US, UK, SA, IND, AUS, CAN,RUS, JPN.... etc..)
For Example:
Locations for US (NY, CA, OKH, WC...... etc.)
Locaitons for UK (SC, ENG, WL..... etc) and so on......
Departments for CA (HR, IT, ADMIN, FIN, TRVL, OPRN........ etc. ..)
Thanks in advance... It will be really great help if I get some breakthrough...

Hi,
what if you add a transient attribute to those view objects? This way you don't need to change the table structure.

Tree table-initially expand all nodes raises error when closing a node 11g

Hello,
Frank Nimphius posted a blog entry about how to initially display all the nodes in a tree or table here:
[http://thepeninsulasedge.com/frank_nimphius/2007/12/19/adf-faces-rc-initially-expanding-all-nodes-in-a-tree-or-tree-table/|http://thepeninsulasedge.com/frank_nimphius/2007/12/19/adf-faces-rc-initially-expanding-all-nodes-in-a-tree-or-tree-table/]
This works very well. However, when the user tries to close a node, a NullPointerException is thrown.
Below is the stacktrace.
Does anyone know how to work around that issue?

OK I have tried Frank's suggestion about the 2 entries in the managed bean and it works but I cannot collapse my child node !
I have a Master-Detail-Detail setup.
In the Grandparent I have this :
RowKeySet rks = new RowKeySet(true);
table1.setDisclosureState(rks);
this.grandParentTable = table1;
and in my Parent table I have this :
RowKeySet rks = new RowKeySet(true);
table2.setDisclosureState(rks);
this.parentTable = table2;
ie the same.
In my child I have nothing just the default accessors.
The collapse works OK for the Grandparent but when I click Hide for the Parent it does not do anything - no error message either.
cheers

By default all nodes expanded in tree table in jsff page in adf

Hi All,
I have a jsff page there is a table tree on it.I want it to be expanded on page load(or default behavior).
How will I achieve it.
This is to be noted that this jsff page so I can not use before phase or after phase.
There is a property in tree table which is expandAllEnabled it does not expand nodes of tree.
There is one more property in tree table which is Initially expanded it shows only first node of tree table expanded.
Thanks & regards,
Vikas

Hi,
It means store the variable ps in pageflowscope variable calles expanedAllNodes and use the disclosed property of treetable.
example:
            if (ps == null) {
                ps = new RowKeySetImpl(true);
                ps = new RowKeySetImpl(true);
                ADFContext.getCurrent().getPageFlowScope().put("expanedAllNodes", ps);
            disclosedRowKeys="#{pageFlowScope.expanedAllNodes}"
Thanks

NPE when expanding tree table

Dear All,
I have a treetable in my page, and a button that inserts some rows in master detail hiearchy based on some busniess logic.
And here is my method that expands my tree table which gets called on button click event.
    private void expandAllNodes(){
        org.apache.myfaces.trinidad.model.RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();
        ViewObject iterCust = u.findIterator("IncDetSubmenuCust_VO1Iterator").getViewObject();
        ViewObject iterType = u.findIterator("IncDetSubmenuType_VO1Iterator").getViewObject();
        ViewObject iterSubmenu = u.findIterator("IncomeDetailSubmenus_VO1Iterator").getViewObject();
        ArrayList<Key> submenuList = new ArrayList<Key>();
        for(Row rowCust=iterCust.first(); rowCust!=null; rowCust=iterCust.next()){
            ArrayList<Key> custList = new ArrayList<Key>();
            custList.add(rowCust.getKey());
            if(iterType.getEstimatedRowCount()>0)
            disclosedTreeRowKeySet.add(custList);
            for(Row rowType=iterType.first(); rowType!=null; rowType=iterType.next()){
                ArrayList<Key> typeList = new ArrayList<Key>();
                typeList.addAll(custList);
                typeList.add(rowType.getKey());
                if(iterSubmenu.getEstimatedRowCount()>0)
                disclosedTreeRowKeySet.add(typeList);
                for(Row rowSubmenu=iterSubmenu.first(); rowSubmenu!=null; rowSubmenu=iterSubmenu.next()){
                    submenuList.add(rowSubmenu.getKey());
        //disclosedTreeRowKeySet.add(submenuList);
        if(treeTableSubmenus !=null)
        treeTableSubmenus.setDisclosedRowKeys(disclosedTreeRowKeySet);
            u.addPartialTargets(treeTableSubmenus);
    }Now when i click the button first time the treetable expands perfectly shows some new master detail hiearchy,
Then when i click the button second time(busniess logic cond chnged, inserted some new rows in master detail hiearchy) and call this method it gives ,me NPE as following stacktrace.

Hi Sireesha,
thanks.
You should have got few more exceptions stating line number at which the exception has raised, can you check your log?Yes i checked my log.. the exceptions is not raised from my code, its from adf internal lib.
And it is very difficult trace out the problem without knowing much details on the insertion logic and the relationship of your iterators.
Can you put more details.Sure
IncDetSubmenuCust_VO1
with (1-*)
IncDetSubmenuType_VO1
with(1-*)
IncomeDetailSubmenus_VO1basically i am inserting the records in IncDetSubmenuType_VO1 & IncomeDetailSubmenus_VO1 only..
on second attempt its giving me NPE.. as shown in my previous post.
I am inserting the records and then calling my expandAll() method.
As seen in logs, the NPE is not raised from my code. Seems like some ADF bug or something...
Thanks,
Santosh.

Tree expand/contract refreshes page

Hi I'm using APEX version 3.1. I have a question regarding a tree. When I expand or contract the tree, the page will refresh. When that happens all my fields which
contain freshly entered data will lose that data.
Is there a simple method to avoid this kind behavior? I can think of a java script which builds the url but I'm hoping for something less complex.
Kind regards,
Patrick

Instead of reloading the page, try submitting it (and not clearing its cache). That should save the item values.

Tree Table icons not getting cleared even after applying the CSS

Hi,
I need to change the tree table expanded and collapsed and the lead node icon.
Leaf node icon is getting changed properly but the remaining two are appled improperly.
In the background the old default image is getting redered and on top of that the newly given image is shown.
These are .css statemets used for changing the icons.
af|treeTable::expanded-icon{content:url(/org/calwin/ui/superweb/image/yellowBlueMarker-minus_trans.gif);
background: none ;}
af|treeTable::collapsed-icon{content:url(/org/calwin/ui/superweb/image/yellowBlueMarker_trans_plus.gif);
background: none}
af|treeTable::leaf-icon{content:url(/org/calwin/ui/superweb/image/blueCircleMarker_trans.gif);
background: none}
Can someone suggest a solution for this.
Thanks,
Praveen.

Hi Frank,
I tried including -tr-inhibit:all;
but it didn't work.
Here's my skin registration tag in trinidaad-skins.xml
<skin>
<id>customSkin.desktop</id>
<family>CustomSkin</family>
<extends>fusion.desktop</extends>
<render-kit-id>org.apache.myfaces.trinidad.desktop</render-kit-id>
<style-sheet-name>org/calwin/ui/superweb/skin/css/customFusion.css</style-sheet-name>
</skin>
Can there be any other reason for not being applied properly.
The images mentioned in the css are properly rendered but in the background
default images are still coming.
Please suggest..

How to define 'First Vsible row' for Tree table in Web Dynpro

Hi,
I am using a table with a treebykeytablecolumn. The user can change the selected
line from another view and then I change the selected line within the tree according to his choice. This works fine.
Unfortunatelly, I did not succeed to change the displayed page in the tree, so the user has to scroll up or down to see the selected data, if it is not on the current page.
I try to bind the 'FirstVisibleRow', using the index of the selected element, but this
index does not fit. The page changes, but as the index is somehow 'wrong', it is not
the expected page that is shown.
Looping at the node, my selected element get index 30, but the selected line is the 8th one (regarding what is current ly open or not in the tree) and the 14th if we expand all nodes above.
So, is there a way to specify which line to be the 1st visible one when there is a tree column?
thanks a lot for your help.
reagrds,
barbara

Follow these steps,
1- Create an attribute with char1 in the view context e.g first_vis_row
2- go to the table properties in view and bind the property first_visible_row to this attribute.
3- NOw go to the wddoinit method of the view...
4- read the internal table and find out the index of the row which you want to set as first row. As in ur case you want a specific date in first row. So read the internal table and findout the index.
5- now write this code, say your attribute name is first row inside node flag1...(you can change it for yoru requirement)
DATA lo_nd_flag1 TYPE REF TO if_wd_context_node.
DATA lo_el_flag1 TYPE REF TO if_wd_context_element.
DATA ls_flag1 TYPE wd_this->element_flag1.
DATA lv_first_row LIKE ls_flag1-first_row.
* navigate from <CONTEXT> to <FLAG1> via lead selection
lo_nd_flag1 = wd_context->get_child_node( name = wd_this->wdctx_flag1 ).
* get element via lead selection
lo_el_flag1 = lo_nd_flag1->get_element( ).
* get single attribute
lo_el_flag1->get_attribute(
    EXPORTING
      name = `FIRST_ROW`
    IMPORTING
      value = lv_first_row ).
here change the lv_first_row to the index which you got after raeading the internal table.
suppose it's
lv_first_row = 4.
lo_el_flag1->set_attribute(
    EXPORTING
      name = `FIRST_ROW`
      value = lv_first_row ).
Hope it works.

How to display the icon as folder in tree table representation

I am displaying the hierarchical structure for one table in which the expanding comes like normal ">". But i want to make it like folder icon.How is it possible plz suggest me.
Thanks,

The folder icons are added in the node stamp of the tree table.
<f:facet name="nodeStamp">
<af:column headerText="Directory Name" width="200" sortable="true" rowHeader="unstyled"
sortProperty="name" id="c2">
<af:panelGroupLayout id="pgl2">
<af:image source="#{directory.icon}" id="nodeIcon"
inlineStyle="margin-right:3px; vertical-align:middle; height:16px; width:16px;"
shortDesc="directory"/>
<af:outputText id="directoryStamp" inlineStyle="vertical-align:middle" value="#{directory.name}"/>
</af:panelGroupLayout>
</af:column>
</f:facet>
You can see the full source if you click the 'view source' link in the menu bar of the demo.

How to disable a node in ADF Tree Table?

Hi,
I'm using JDeveloper version - 11.1.1.7
I have a requirement to disable the nodes in Tree table based on status of the node. How can I achieve this?
Any inputs would be helpful.
Thanks
Ravi

Hi,
you cannot disable nodes in the sense that they cannot be expanded or selected. What you can do though is to ignore node selections in a custom selection handler or to render the node different (e.g. using an output text component instead of a command link or image etc.). What is your functional requirement for what disabled nodes should not do
