ADF Dynamic Table Generation

Hi, I'm trying to generate dynimic tables from my backing bean and i can't get it work, i've looking on the web and many forums, and this is the only example i've found :
public void setDataTable(UIXTable param) {
this.dataTable = param;
if(!columnsBound) {
// Bind to the table
List<SearchResultsColumn> cs = this.getColumns();
for(int c = 0; c < cs.size(); c++) {
CoreColumn col = new CoreColumn();
SearchResultsColumn colDef = cs.get(c);
col.setHeaderText(colDef.getName());
CoreOutputText coldata = new CoreOutputText();
FacesContext.getCurrentInstance().getApplication();
coldata.setValueBinding("value", FacesContext.getCurrentInstance().getApplication().createValueBinding("#{row.cellArray.value}"));
col.getChildren().add(coldata);
col.setHeaderText(colDef.getCaption());
this.dataTable.getChildren().add(col);
This code is useless for me, because i'm using a version of JDeveloper and ADF that has deprecated methods like createValueBinding(xx) (JDeveloper 11g). I'll be gratefull for any help with this problem.
Thanks!
Giorgio

Dynamic table generation for Employee Schedule Project

Hi,
I am new to Jave programming and attempting to teach myself Java using the Sun tutorials & these forums. As a first step of learning, I want to do a Automated Employee Schedule Project in Java. (JSP)
There are two main parts of the project. The first part will be a table with the employees listed down the left, the days of the week across the top, and with each cell being that employee's shift for the day. There are four different types of shift in a day ( M- Morning, R- Regular, A- Afternoon and N- Night).
The second part will allows the user to enter in a new employee or display/edit an existing employee's information, including a list of scheduling constraints, like can?t work in Morning shift / Night shift. Apart from that number of employee in a shift may vary based on situation.
Could you please help me to understand the flow for creating this Automated Employee Schedule project?
Thanks in advance.
Amitava

I need the logic as to how to generate the shift plan. Could you tell me how to get about creating this dynamic table and any idea what i should take as baseline? I was thinking to read the employees from the database and take them as input for the first column. and the number of days as the column list. Can you tell me if this is the correct approach?

Creation of ADF dynamic table

i want to create a table where the columns are fixed but the rows should be added dynamically and user can insert data into the rows so that the data will be inserted into the database tables.When the data is saved by clicking save button the row will be reset and at a time we can see only a single row.please tell me how to implement this using ADF-BC.
please give the solution using ADF-10g

Thanks for the reminder, but licensing is covered by my organisation. I am really concerned about the technical aspects of my question.
Regarding Vit's post, I do not understand fully why "Well, partitioning on "data" seems to be a bad idea, if it contains other values than just dates (as you indicate)." I would partition on data, the problem is that the governing field is not a column per se, but rather contained in the data column together with other information. I'll make it more clear:
column 1: fiche id
column 2: data code
column 3: data itself
Thus, a "fiche" would consist of several records, each containing diverse information, for example:
fiche code data
1 10 01/01/2007 (i.e. the date I would use for partitioning)
1 20 Acme (e.g. name of manufacturer)
1 30 1000000 (e.g. revenue in 2007)
1 40 WaltDisney st. (e.g. address)
and so on
So, it is not so straight forward to use a column for partitioning, I actually need the combination of code and data to know what data to use. Otherwise I would use hash partitioning.
Regarding the keys, the obvious columns are fiche and code, being the combination of both, unique. A typical query would want to search for data in the data column (i.e. year), for which I also need column code (I need to know what code is the type of data year before I can ask for it). Indexing of data would be necessary.
Finally, the data would be accessed through an SQL editor. The end user would have freedom to build own queries. Just for information, a select count on the partially loaded table (bit more than 95 million records = ~9% of foreseen load) without indexes takes about 1 min 20 seconds to complete.
One more thing I forgot to mention: the table will have inserts (not frequent, but maybe massive) and not updates.

Dynamic table generation, an OOP question, and .

I am attempting to teach myself Java using the Sun tutorials (mostly DiveLog) and these forums. So far, things are going well.
My application is a scheduling program for my current boss. I work in retail, and the app would (ideally) faciliate creating the weekly schedules. I am using Swing to generate the windows and such.
There are two main parts to the app, each corresponding to a tabbed pane. The first part will be a table with the employees listed down the left, the days of the week across the top, and with each cell being that employee's shift for the day. Totals for hours worked that week will be the farmost right column and totals for hours of coverage that day will be the bottom row. The second part of the app allows the user to enter in a new employee or display/edit an existing employee's information, including a list of scheduling constraints (e.g., can't work mornings Tu/Th because of class).
My intuition is that the schedule table and the list of scheduling constraints should be dynamically generated and displayed depending on the number of employees and the number of constraints. It would also seem that both parts of the application need access to the current set of data encompassing all employees and their information. As I am just starting, the work I have done so far has been in the employee info section where I am in the process of implementing an MVC architecture with the model as a sort of employee datagram.
The questions....
1. How do I draw tables with a dynamic number of rows? I want the scheduler table to have a row for each employee and have the number of employees not hardcoded in. With the list of scheduling constraints, could I just have Swing draw each new row from a loop that counts down the number of constraints?
2. What is the smart move regarding having multiple parts of the app/GUI access employee data? Would I just load the data into an object when the app starts and have the two parts access the info via 'get' functions? (And subsequently have the second part of the app be able to edit the data via 'set' functions and then tell the first part of the app update itself?)
3. Is it appropriate to use reading and writing to and from a file for this sort of activity? (As opposed to a database of some sort.) The DiveLog app uses object serialization, and I'm feeling sketchy in this area, particularly with accessing specific pieces of data from whatever gets read from a file. If the user selects an employee from a JComboBox, how do I take that selection and grab the right object from the stuff that's been read back from a file? Similarly with the scheduling table.

Dynamic table generation

Hi everybody !
I'm using Adobe LiveCycle Designer ES free trial.
I have a set of data and two pdf. The first is a pdf i got on the web, which was created with Adobe LiveCycle Designer ES full version.
The second is the one i created with the trial version.
I'm trying to display several data like this:
    <history>
        <date>08/05/2009</date>
        <doc>doc</doc>
        <desc>desc</desc>
    </history>
    <history>
         <date>09/05/2009</date>
         <doc>doc</doc>
         <desc>desc</desc>
     </history>
With the first pdf it works fine. All the data are displayed.
But only one data is displayed with mine.
I checked all the options (like binding) and there are all the same on the two pdf.
So is there a limitation on the trial version with repeating data ??
Thanks

No there are no limitations in the trial version, but the one you got from the web is probably saved as a dynamic PDF and yours is probably not saved that way.

Dynamic Table in PDF - only first row passed to the WD Java

Hi Experts,
I'm working with Web Dynpro for Java on WAS 2004s SP13, ADS for SP13 and LiveCycle Designer 7.1
I am facing a problem related to PDF-dynamic table generation.
I am creating the PDF form with a dynamic table, an empty row will be added, when ADD button is clicked, the row will be deleted when DELETE button is clicked. After form submit, only first row of the table is passed to the Web Dynpro. I'v tried to use different dataSource Context node structure without results. The structure diescribed in the thread [Dynamic Table - same data repeating in all rows; doesnt works for me. The same happend if i try to folow the advise from Wiki https://wiki.sdn.sap.com/wiki/display/WDJava/Creating%20Table%20in%20Interacting%20form%20using%20Web%20Dynpro.
Beside this, my DropDown list in the table column is not populated. I know how to populate the DropDown list outside of table. That's working fine. But the DropDown in the table just not respond on the click (is not going open). I'm pretty sure that this is a result of a Context node structure/binding issue.
Please suggest me how can i implement dynamic table and populate the data in table dropdown column.
Edited by: A. Mustacevic on Sep 7, 2009 12:18 AM

Hi Prabhakar,
You describe exactly my situation. The node which is bound to the table row has cardinality 1..n. Exactly Context structure is:
node dataSource (cardinality 1..1/ Singleton true) ======> dataSource of the Interactive Form
subnode TableList (cardinality 1..1/ Singleton true) ======> bound to the table in the Interactive Form
subnode TableWrapper (cardinality 1..n/ Singleton true) ======> bound to the table row in the Interactive Form
subnode TableData (cardinality 0..1/ Singleton false) ======> table data
attribute 1 ====> Context nodeattribute bound to the table row field
attribute 2
This structure is recommanded in the post that I found on the Forum (see the firs hyperlink in my firs post).
Is this structure correct? Why is not working?
Your link is not working. Can you post the correct one.
Thanks in advance.
Regards
Adnan

Dynamic Tables: TableCellEditor depending on Context node value

Dear community,
I'm creating a dynamic table containing all the neccessary fields to display my context node in Java code but I have one requirement that I can not resolve by myself:
Depending on the value of a cell the TableCellEditor should be of type IWDTextView or LinkToURL. So if the context node value is e.g. the String "abc" I want to display a LinkToUrl containing a Target - such as http://www.abc.com - depending on the value, if the context node value is "def" I want to do nothing but display the value in a TextView.
As I am creating the dynamic table in advance and binding my Context node to it later, I don't know how to change the TableCellEditor at that point of time.
Right now I have the choice to either display all cells of the column as LinkToUrl TableCellEditor or display all cells as TextView - the dynamic table generation itself is no problem for me.
Does anyone have an idea on how to do that? Maybe it is not possible in WDJ right now?
regards,
Christian

Hi Christian
Try this:
IWDTable theTable=(IWDTable)view.createElement(IWDTable.class,"table");
IWD TableColumn aColumn=(IWDTableColumn)view.createElement(IWDTableColumn.class,"col");
if(str.equal("abc"))
IWDTextView aField=(IWDTextView)view.createElement(IWDTextView.class,"TextView");
aField.bindText(str);
aColumn.setTableCellEditor(aField);
else if(str.equal("def"))
IWDLinkToURL aField=(IWDLinkToURL)view.createElement(IWDLinkToURL.class,"LinkToURL");
aField.bindtarget("http://www."str".com");
aColumn.setTableCellEditor(aField);
theTable.addColumn(aColumn);

Image not displaying on a dynamic Table !

Dear Friends,
In my assignment, I would like to display the Status column of a table with different image as per the data received from backend system.
Infact it is a dynamic table generation. The code snippet is as below:
IWDNodeInfo tabNode=wdContext.getNodeInfo().getChild("Reports_TAB");
String colName="Status";
String imagePath=tabNode.getAttribute(colName).toString();
IWDImage colImage=(IWDImage)view.createElement(IWDImage.class, colName+"Image");
colImage.setSource(imagePath);
But problem, is imagePath is hold the value as DataAttributeInfo(DashBoardView.It_FinalTAB.Status), instead of actual image name.
(Ya, Image is stored in src/mimes/Components/<component>/ folder, which is working absolutely fine with test example.)
Because of this, image is not displaying on the table elements.
Can anybody help me, how can retrive exact image name from the tabNode?
Thanks in advance,
Lakshmikantha

Hi Lakshmikantha,
Instead of Doing colImage.setSource() you have to do collmage.bindSource()
IWDNodeInfo tabNode=wdContext.getNodeInfo().getChild("Reports_TAB");
String colName="Status";
IWDAttributeInfo imagePath=tabNode.getAttribute(colName);
IWDImage colImage=(IWDImage)view.createElement(IWDImage.class, colName+"Image");
colImage.bindSource(imagePath);
What we have done here is when the table column is created we are mentioning that at runtime for each record the image source has to be taken from the attribute value of "Status". This will only work if at runtime the value coming in the Attribute Status has the image path (relative path).
If for instance you dont have the image path coming from the backend but only the status code and you have to decide which image to show at runtime. This is mostly the case. Then under the node "Reports_TAB" you will have to create a calculated attribute of type String. The calculated attribute will generate a getter method which will accept the current record and return the string. You will have to write code to extract status from the current record and return the appropriate path.
The binding of the Image table column should now point to the newly created calcuated field instead of the field Status.
Hope this helps.

Sanyev

PDF - Dynamic Table

Hi,
I am facing one problem related to PDF-dynamic table generation. Suppose I have designed the master page and i have the company logo as header in all the pages and my body page has one table designed. I have choosen Flow Layout for the table but when the tables has many rows, it is extending to the next page but problem is that these rows are overlapping with the header of the next page(Company Logo). Is there any way we can keep the Master page header fix and the extra table rows from the first table will be displayed that only.
Your sugestion is highly welcome.

Hello,
You can create multiple master pages with different layouts for 1st and following pages.

[SOLVED] Multiple Dynamic View Objects and View Links - ADF Tree Table

Hi all,
I've got a method that creates 3 dynamic viewobjects using this:

How to create bindings at runtime for Dynamic Tables ?

We have lot of Dynamic tables, In ADF, we need to try out the Dynamic EO, Dynamic VO, Dynamic DataControl and Dynamic binding for UI
Ex:
We need to load the data to the ADF table where database table name is dynamic, the columns in the tables are also dynamic. At runtime , we need to create VO, Dynamic binding and display to UI? We also should be able to add, delete,update records in the dynamic tables.
Does anyone done this before? Please shared your thoughts on this

Hi,
for a table you can declaratively build a tree binding. Then you remove all the attribute items in the tree definition so that the number of attributes is dynamic. See: https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf

An extra column of a query in an ADF Faces Table?

Hi to all OTN Community...
I use ADF Faces, Toplink and EJB 3.0 in JDevelooper 10.1.3.1.0, and i have a question...
I need to show in an adf faces table, the result of a query like this
SELECT COLUMN1, COLUMN2, COUNT(*)
FROM TABLEX
GROUP BY COLUMN1, COLUMN2
I do this query in the TableX named queryes...and then i have acces to this named query in the dataControl, but, when i drag and drop the dataControl to a jsf page, this only shows the columns of the tableX. Then, i want to know, ¿How can i show the count(*) column in the page in a dataControl?
PD: i want to show in the adf faces table the same result if i execute that query in an sql client.
Thanx in advance...
Darklorddany

Darklorddany,
The solution to this is to add an additional method on your EJB 3.0 session-bean that exposes an dynamic TopLink report (projection) query.
The TopLink code within the method would leverage your existing TopLink mappings to do the query like:
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);The ReportQueryResult objects are very generic map/row type containers that will not work well in your ADF binding layer. With JPA you can specify and ad-hoc Java class to contain such projection results that make them a little easier to use in clients. This functionality will be available in the next release of TopLink. Until then you will need to write some code to convert to your own result class for this query.
In my case I'll create a simple POJO like:
    public class EmployeeNameCount {
        private String firstName;
        private String lastName;
        private int count;
        public EmployeeNameCount(String firstName, String lastName, int count) {
            this.firstName = firstName;
            this.lastName = lastName;
            this.count = count;
        public String getFirstName() {
            return this.firstName;
        public String getLastName() {
            return this.lastName;
        public int getCount() {
            return this.count;
    }Now I combine the previous report query code into an EJB 3.0 session bean method:
    @TransactionAttribute(TransactionAttributeType.SUPPORTS)
    public List<EmployeeNameCount> findEmployeeNamesWithCount() {
        Session session = getSessionFactory().acquireSession();
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);
        session.release();
        List<EmployeeNameCount> empNameCounts = new ArrayList<EmployeeNameCount>(results.size());
        for (ReportQueryResult rqr: results) {
            String fname = (String)rqr.getByIndex(0);
            String lname = (String)rqr.getByIndex(1);
            int count = ((Number) rqr.getByIndex(2)).intValue();
