Dynamically Binding to Dynamically Create View

I tried to copy the code of Dynamically Binding to Dynamically Create View object but something is wrong because when I am debbuging it doesnt work after the sentence vo.executeQuery();
I suspect that the reason could be how I created the view..
Your code is running well but not mine.
It shows this error
JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
null
I dont know why because the code is the same.
How did you create the objet view ?
Could you help me?

I'd recommend checking out this article on Debugging ADF Applications:
http://www.oracle.com/technology/products/jdev/tips/muench/debugger/index.html
and then reporting here the full stack trace using the tips described in that article.

Not Yet Documented ADF Ex 9 Dynamically Binding to Dynamically Created View

I have dynamically created a View Object and would like to build a dynamic HTML Table on a web page based upon my view. I think something similar is done in Steve Muench's sample #9. My problem is I am new to ADF and the example was done in an earlier version of JDev (I am using 10.1.3.0.4) and the JSP page in the example will not compile. I get an error at:
<textarea style="width: 100%" name="sql" rows="3" ><c:out value="${param.sql}"/></textarea><br>
Saying required param "cols" is missing. I also get a nesting error in this code:
<tr>
<c:forEach var="attributeLabel" items="${bindings.DynamicViewObject.labelSet}">
<th>
because (I think) the compiler expects a </tr> and it is seeing the <c:forEach var="attributeLabel"> tag.
Is there a setting in JDeveloper I can use to allow this application to compile? Is there a similar example done in JSF as that is what my current application is being developed using.
TIA,
Jeff

Any help on this? Kind of Urgent...
Thanks,
Jeff

Dynamic binding of items in sap.m.Table using XML views

Dear SAPUI5 guru's,
Let's start by saying I'm an ABAP developer who's exploring SAPUI5, so I'm still a rookie at the time of writing. I challenged myself by developing a simple UI5 app that shows information about my colleagues like name, a pic, address data and their skills. The app uses the sap.m library and most of the views are XML based which I prefer.
The data is stored on an ABAP system and exposed via a gateway service. This service has 2 entities: Employee and Skill. Each employee can have 0..n skills and association/navigation between these 2 entities is set up correctly in the service. The data of this service is fetched from within the app using a sap.ui.model.odata.ODataModel model.
The app uses the splitApp control which shows the list of employees on the left side (master view). If a user taps an employee, the corresponding details of the employee entity are shown on the right (detail view).
Up till here everything is fine but I've been struggling with my latest requirement which is: show the skills of the selected employee in a separate XML view when the user performs an action (for the time being, I just created a button on the detail view to perform the action). After some hours I actually got it working but I doubt if my solution is the right way to go. And that's why I'm asking for your opinion here.
Let's explain how I got things working. First of all I created a new XML view called 'Skills'. The content on this view is currently just a Table with 2 columns:
<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"
controllerName="com.pyramid.Skills" xmlns:html="http://www.w3.org/1999/xhtml">
<Page title="Skills"
       showNavButton="true"
       navButtonPress="handleNavButtonPress">
<content>
<Table
   id="skillsTable">
<columns>
<Column>
<Label text="Name"/>
</Column>
<Column>
<Label text="Rating"/>
</Column>
</columns>
</Table>
</content>
</Page>
</core:View>
The button on the Detail view calls function showSkills:
showSkills: function(evt) {
var context = evt.getSource().getBindingContext();
this.nav.to("Skills", context);
var skillsController = this.nav.getView().app.getPage("Skills").getController();
skillsController.updateTableBinding();
Within 'this.nav.to("Skills", context);' I add the Skills view to the splitApp and set its bindingContext to the current binding context (e.g. "EmployeeSet('000001')"). Then I call function updateTableBinding in the controller of the Skills view which dynamically binds the items in the table based on the selected employee. So, when the ID of the selected employee is '000001', the path of the table's item binding should be "/EmployeeSet('000001')/Skills"
updateTableBinding: function(){
var oTemplate = new sap.m.ColumnListItem(
{cells: [
          new sap.m.Text({text : "{Name}"}),
          new sap.m.Text({text : "{Rating}"})
var oView = this.getView();
var oTable = oView.byId("skillsTable");
var oContext = oView.getBindingContext();
var path = oContext.sPath + "/Skills";
oTable.bindItems(path, oTemplate);
Allthough it works fine, this is where I have my first doubt. Is this the correct way to bind the items? I tried to change the context that is passed to this.nav.to and wanted it to 'drill-down' one level, from Employee to Skills, but I couldn't manage to do that.
I also tried to bind using the items aggregation of the table within the XML declaration (<Table id="skillsTable" items="{/EmployeeSet('000001')/Skills}">). This works fine if I hard-code the employee ID but off course this ID needs to be dynamic.
Any better suggestions?
The second doubt is about the template parameter passed to the bindItems method. This template is declared in the controller via javascript. But I'm using XML views! So why should I declare any content in javascript?? I tried to declare the template in the XML view itself by adding an items tag with a ColumnListItem that has an ID:
                <items>
                    <ColumnListItem
                    id="defaultItem">
                    <cells>
                        <Text text="{Name}"/>
                        </cells>
                        <cells>
                        <Text text="{Rating}"/>
                        </cells>
                    </ColumnListItem>
                </items>
Then, in the updateTableBinding function, I fetched this control (by ID), and passed it as the template parameter to the bindItems method. In this case the table shows a few lines but they don't contain any data and their height is only like 1 mm! Does anyone know where this strange behaviour comes from or what I'm doing wrong?
I hope I explained my doubts clearly enough. If not, let me know which additional info is required.
Looking forward to your opinions/suggestions,
Rudy Clement.

Hi everybody,
I found this post by searching for a dynamic binding for well acutally not the same situation but it's similar to it. I'm trying to do the following. I'm having a list where you can create an order. On the bottom of the page you'll find a button with which you're able to create another order. All the fields are set to the same data binding ... so the problem is if you've filled in the values for the first order and you'll press the button you'll get the same values in the second order. Is it possible to generate a dynamic binding?
I'm going to post you a short code of what I'm meaning:
<Input type="Text" value="{path: 'MyModel>/Order/0/Field1'}" id="field1">
     <layoutData>
                <l:GridData span="L11 M7 S3"></l:GridData>
           </layoutData>
</Input>
As you can see I need to set the point of "0" to a dynamic number. Is there any possibility to reach this???
Hope you can help
Greetings
Stef

A dynamic table based on run-time created view object -- please help!

Hello!
I'm trying to create a dynamic table based on an run-time created view object. All go ok, but table binding component take the first view/iterator state and don't reflect changes they have. Please, take a look:
1. At run-time the view is being replaced by new red-only one based on query in application module:
getQueryView().remove();
createViewObjectFromQueryStmt("QueryView", statement);
2. Page definition file contains an iterator (using iterator or methodIterator - doesn't matter) binding and table, which binds to the iterator, like:
<methodIterator id="distributeQuery1Iter" Binds="distributeQuery1.result"
DataControl="QueryServiceDataControl" RangeSize="10"/>
<table id="distributeQuery11" IterBinding="distributeQuery1Iter"/>
3. The page code uses <af:table>. But, if I use table binding (it's right) like this:
<af:table var="row" value="#{bindings.distributeQuery11.collectionModel}">
<af:forEach items="#{bindings.distributeQuery11.attributeDefs}" var="def">
the table will never changed (i.e. still show the first view instance).
When I tried to use iterator binding directly (it's bad and cannot provide all needed features unlike CollectionModel from table binding) I saw that table works!
(Code is somehing like:
<af:table var="row" value="#{bindings.myIterator.allRowsInRange}">
<af:forEach items="#{bindings.myIterator.attributeDefs}" var="def">
Why the table binding do not reflect changes in iterator? Or should I use different approach?
Thanks in advance!
Ilya.

I got it to work! I used a hybrid approach comprised of some of your code and some of Steve Muench's AcceessAppModuleInBackingBean example.
In the setBindings method, I execute an app module method that redefines the query, then I used your code to delete and recreate bindings and iterator:
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
rebuildVO();
The rebuildVO() method looks like the code you provided in your example:
private void rebuildVO() {
DCDataControl dc;
DispatchAppModule dApp;
DCBindingContainer bc;
DCIteratorBinding it;
OperationBinding operationBinding;
ViewObject vo;
DCControlBinding cb;
try {
bc = getBindingContainer();
dc = bc.findDataControl(DATACONTROL);
dApp = (DispatchAppModule)dc.getDataProvider();
// Execute App Module Method to rebuild VO based upon new SQL Statement.
dApp.setDispatchViewSQL();
vo = dApp.findViewObject(DYNAMIC_VIEW_NAME);
it = bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME);
it.bindRowSetIterator(vo, true);
// logger.info("Remove value binding...");
cb = bc.findCtrlBinding(DYNAMIC_VIEW_NAME);
cb.getDCIteratorBinding().removeValueBinding(cb);
bc.removeControlBinding(cb);
// logger.info("Creating new value binding...");
FacesCtrlRangeBinding dynamicRangeBinding =
new FacesCtrlRangeBinding(null,
bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME), null);
// logger.info("Add control binding...");
bc.addControlBinding(DYNAMIC_VIEW_NAME, dynamicRangeBinding);
} catch (Exception e) {
e.printStackTrace();
And my App Module method that redefines the view object looks like this:
public void setDispatchViewSQL() {
String SQL =
"begin ? := PK_BUsiNESS.F_GETDISPATCHVIEWSQL();end;";
CallableStatement st = null;
String ViewSQL = null;
try {
st = getDBTransaction().createCallableStatement(SQL,
DBTransaction.DEFAULT);
* Register the first bind parameter as our return value of type LONGVARCHAR
st.registerOutParameter(1, OracleTypes.LONGVARCHAR);
st.execute();
ViewSQL = ((OracleCallableStatement) st).getString(1);
findViewObject(DYNAMIC_VO_NAME).remove();
ViewObject vo = createViewObjectFromQueryStmt(DYNAMIC_VO_NAME, ViewSQL);
vo.executeQuery();
} catch (SQLException s) {
throw new JboException(s);
} finally {
try {
st.close();
} catch (SQLException s) {
s.printStackTrace();
When I run it I get my desired results. One thing I don't quite understand is why when the page is first rendered it shows the last set of records rather than the first. Now I have to figure out how to put navigation URLS in each of the table cells.
Thanks for your help; I would not have gotten this far without it,
Jeff

Problem with embeding the same view in dynamically created view container

Hello Experts,
              I am getiing a dump when i try to embed the same view inside the dynamically created view container of
dynamically created tabs of a tabstrip
The requirement go like this, i have 2 views in which i have have to embed the 2nd view to view1 where i have an empty
tabstrip without tabs. During runtime i create tabs as well as view containers accordingly and then try to embed view2 in tabs.
I have put the below mentioned code in HANDLEIN,
DATA: lref_vcntlr TYPE REF TO if_wd_view_controller,
        lref_comp    TYPE REF TO if_wd_component_usage,
        lv_embed_pos TYPE string.
lref_vcntlr = wd_this->wd_get_api( ).
lv_embed_pos = 'FILE_PERS_EDIT/VC_GENERAL'.
TRY.
      CALL METHOD lref_vcntlr->do_dynamic_navigation
        EXPORTING
          source_window_name        = 'FILE_PERSISTENCE_WND'          " Window
          source_vusage_name        = 'FILE_PERS_EDIT_USAGE_1'       " Source View usage
          source_plug_name          = 'TO_EDIT_LAYOUT'                       " Outbound plug
          target_view_name          = 'PERS_EDIT_LAYOUT'                  " Second view to be embedded
          target_plug_name          = 'IN'                                                  " Second view inboun plug
          target_embedding_position = lv_embed_pos
        RECEIVING
          component_usage           = lref_comp.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_edit_layout_plg( ).
This works fine for the first time.
However onaction tab select i change the embeding position( 'FILE_PERS_EDIT/view container name of different tab') of the view2 an try to embed view2 in a different tab.
At this point i get a dump stating View2 already present in the window 'FILE_PERSISTENCE_WND' of component.
I think, the view2 embediing has to be removed before i add the view2 in a different tab
Kindly let me know how to remove view2 embedding from tab1 before i add a view2 to a different tab or is there any other
means to handle this problem?
Thanks & Best Regards,
Srini.

Hello Srini,
I found a solution to your problem, because I had a similar task.
In WDDOINIT I changed the method do_dynamic_navigation to if_wd_navigation_services_new~prepare_dynamic_navigation:

          source_vusage_name        = 'VW_SUB_USAGE_1'
          source_plug_name          = 'TO_VW_CONTENT'
          target_component_name     = 'ZTEST_DYNAMIC'
          target_view_name          = 'VW_CONTENT'
          target_plug_name          = 'DEFAULT'
          target_embedding_position = 'VW_MAIN/VC_TAB.VW_SUB/TAB1_VC'

wd_this->fire_to_vw_content_plg( param1 = 'TAB1' ).
In the action I first deleted the navigation targets, then navigated to the empty-view and last I called my target view:

About dynamically setting bind variable in LOV View

Hi,
I have a LOV VO for an af:SelectOneChoice field in the page.
The LOV is depended on an SQL statement in which there is a bind variable in the where clause.
When I open the page, I set the bind variable by using VO.setNamedWhereClauseParam in the prepareSession method in the application module, followed by VO.executeQuery();
The problem is, the af:SelectOneChoice is blank. Why?
If I do not use the bind variable in the SQL, I can see rows in the af:SelectOneChoice field.
When is the proper time to populate the LOV? And where should I put the code for populating the LOV?
I am sure that the VO is populated, because after I executeQuery, there are many rows in the VO.
Thanks
Stephen

Hi Franky,
Yes, when I set a default value for the bind variable, everything is OK.
But I want the bind variable dynamically be set when the AM is initiated. Is there a way to do that?

Dynamically binding backing bean

Dynamic binding of backing bean
Here is a problem that I have been trying to solve. Maybe someone can have a go at it:
Here is a Search form(Simplified version):
af:selectOneChoice - to choice a 'class family' e.g., companies, NGO, charity, institution etc
af:inputText - to enter a name
af:commandButton – to search
Here is a User task:
1.     Choose a 'class family' from the selectOneChoice
2.     Enter a name in inputText
3.     Click commandButton to start the search
Additional information
1. The number of 'class family' is about 30 and requires different method of search.
2. I want to use a uniform search user interface and so there is only one page for all.
3. Each 'class family' has it own managed bean in face-config.xml.
Scenario:
Lets say the searchUI.jsp has an initial backing bean called SearchBean.java. The af:selectOneChoice in searchUI.jsp has a valueChangeListener and when the user chooses a 'class family' at step (1), the valueChangeListener in SearchBean.java is triggered.
Problem:
The problem is how do I dynamically switch the backing beans, say from SearchBean.java to SearchCompanyBean.java so that when the user next click the search commandButton, it is the searchAction method in the SearchCompanyBean.java and NOT the initial SearchBean.java that handles the action.
Cheers in advance.

Hi,
Assuming you are using ADF BC, have a look at using view criteria. You can define, dynamically apply and remove view criteria on the view object.
Have a look at the help on oracle.jbo.ViewCriteria and applyViewCriteria from the ViewObject implementation class. Sounds like they might meet your requirements.
Create a client method on your VO and drag it onto your page as an ADF parameter form and go from there.

How to create dynamic DataTable with dynamic header/column in JSF?

Hello everyone,
I am having problem of programmatically create multiple DataTables which have different number of column? In my JSF page, I should implement a navigation table and a data table. The navigation table displays the links of all tables in the database so that the data table will load the data when the user click any link in navigation table. I have gone through [BalusC's post|http://balusc.blogspot.com/2006/06/using-datatables.html#PopulateDynamicDatatable] and I found that the section "populate dynamic datatable" does show me some hints. In his code,
// Iterate over columns.
        for (int i = 0; i < dynamicList.get(0).size(); i++) {
            // Create <h:column>.
            HtmlColumn column = new HtmlColumn();
            dynamicDataTable.getChildren().add(column);
            // Create <h:outputText value="dynamicHeaders"> for <f:facet name="header"> of column.
HtmlOutputText header = new HtmlOutputText();
header.setValue(dynamicHeaders[i]);
column.setHeader(header);
// Create <h:outputText value="#{dynamicItem[" + i + "]}"> for the body of column.
HtmlOutputText output = new HtmlOutputText();
output.setValueExpression("value",
createValueExpression("#{dynamicItem[" + i + "]}", String.class));
column.getChildren().add(output);
public HtmlPanelGroup getDynamicDataTableGroup() {
// This will be called once in the first RESTORE VIEW phase.
if (dynamicDataTableGroup == null) {
loadDynamicList(); // Preload dynamic list.
populateDynamicDataTable(); // Populate editable datatable.
return dynamicDataTableGroup;
I suppose the Getter method is only called once when the JSF page is loaded for the first time. By calling this Getter, columns are dynamically added to the table. However in my particular case, the dynamic list is not known until the user choose to view a table. That means I can not call loadDynamicList() in the Getter method. Subsequently, I can not execute the for loop in method "populateDynamicDataTable()".
So, how can I implement a real dynamic datatable with dynamic columns, or in other words, a dynamic table that can load data from different data tables (different number of columns) in the database at run-time?
Many thanks for any help in advance.

Dynamic binding of partner links with different payloads

In dynamic binding of partner links, can we have different payloads for different
webservices ?

Hi Marc,
I have one question regarding the use of <xsd:anyType>, Before that let me clear our requirement. We are trying to create a BPEL flow (Consumer) which has the ability to call other webservices (Producers) dynamically. There can be a number of Producer Webservices performing the same task. The end user should be able to add new Producer Webservices and remove already existing ones. We achieved this using EndPointReference (http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html) but the problem with this approach is that all the producer webservices have to work on a common schema. We want to support webservices working on different payloads.
My understanding is that when we map the XML document to xsd:anyType in the service's WSDL file, the producer web service need to have an implementation of this type in for of a java class. Is this correct ? Or can we provide the java implementation in our code itself? Can you please point me to some detail documentation on xsd:anyType?
Thanks

Dynamically binding VO Parameter from Context Switcher

Hi guys,
I am using ADF JSF and BC, and I have a situation here which is:
1) My JSF page has a panel page component, inside it is a navigable form referencing a View Object.
2) In the contextSwitcher facet of this PanelPage, i have a SelectInputText which points to a "Globals" VO, having only one row ever (similar to SRDemo)
3) When the LOV returns value to this field, i must re-bind the navigable form VO Query to this value, and the form must show the first record of the NEW rowset.
The solution i am writing uses a ValueChangeListener on the SelectInputText, which runs an Application Module method that gets the value from the Globals VO and re-runs the query using "vo.setWhereClause" and "vo.executeQuery".
However, even though i debug the application and see the query being executed, the form shows strange behavior, as the page then re-runs the query, but swaps the first row of the new rowset with the row currently displayed. For example, suppose that i am seeing row "X" on the page and select a value from the LOV. The new execution fetches rows "Y" and "Z" from DB. When i scroll the page, i see that the first record is "X" again, followed by "Z"!
Do you have any idea of what could be the problem? Maybe a form clearance issue with ADF? Or i shouldn't be using dynamic binding with UPDATEABLE fields on the page, only when i use READ-ONLY fields?
Thanks a lot, and regards!
Thiago

Thiago,
you are not showing any of your code and I can only assume that this is a coding problem of yours.

Dynamic binding in Webservices (UDDI)

Hi,
I would like to know if it's possible to create a Webservice proxy (stub) with dynamic binding: I mean, if I change details in the UDDI Registry, because binding is resolved at run-time, I don't need to change any code in proxy.
I'm trying the web service proxy wizard and what creates is a bound proxy. Is there any restriction in the kind of services that are published in the ws registry?
Thanks. Miquel.

Hi,
you could receive the attributes of the node by calling method get_attributes of the node info object.
Afterwards you have to instantiate a RTTI object (cl_abap_structdescr) with a description of the attributes.
Then you have to create the structure by using create data.
Example:
DATA lo_struc_type TYPE REF TO cl_abap_structdescr.
DATA: struc_comp_table TYPE cl_abap_structdescr=>component_table.
DATA: dref TYPE REF TO data.
FIELD-SYMBOLS: <struc> TYPE ANY.
lo_struc_type = cl_abap_structdescr=>create( struc_comp_table ).
CREATE DATA dref TYPE HANDLE lo_struc_type.
ASSIGN dref->* TO <struc>.
In my opinion it is too complicated to realize your requirement in this way...

Dynamic Filter To Sharepoint Calendar View

Hello ,
I want to add Dynamic column filter to Calendar View of sharepoint.
Is there any one has good Approach for this ?
Regards, Shivaji

Hi Shivaji,
In fact, to filter dynamic we can use Filter Web Part, however the Filter Web Part Connections cannot connect to Calendar View by default. In this case, may be you can custom Filter Web Part to achieve your
requirement.

Hi Stevan
I'm using JSP.
Ive used request parameters for binding in the where clause {app_cycle=:1 and college_code='MICH'}in application structure i gave ${param.appcycle},${param.collegecode} , which the page is loaded successfully. Dont know how did that error got cleared. Anyway now session is the problem.
I want to use session and not request parameters.
How to achieve this. I dont understand the help give in the query bind parameters tab in application structure file. It says ${MyObject.MyParameter}
in Jsp session is the object. Assuming that i gave ${session.appcyle} where appcycle is the parameter which holds the value. But it didnt work
Kindly help on this.
regards
Jayashri
