Dynamic Component in Table Column

JDev 11.1.1.6
Can anyone give me guidance on how to change the component that a table column uses at runtime?
Basically, I want to have an Input Text on Column B when the value on the Output Text on Column A is within a list of strings.
Otherwise, I want to have an image on Column B.
Here is the long-winded scenerio:
I have a table with 2 columns (Column A and Column B).
Column A is an OutputText.
Column B is an InputText.
The user is only allowed to enter data into Column B when Column A is 'A', 'B', or 'C'.
If Column A is something other than 'A', 'B', or 'C', I would like to display an image in Column B that alerts the user that they cannot enter any data in this field.
I tried making the InputText read only, but that doesn't look very good.
Any help would be appreciated.

You can add image component to the same column and use rendered property on both af:inputText and af:image to show/hide them.

Dynamic iterating over table columns

hello there,
i have to create a string depending on the values in my table columns. this string creation is used on different tables with different number of columns and different column types.
so i want to write a procedure which does simplified the following:
1. create dynamic rowtype with a select statement
2. iterate over rowtype columns and append column value to a string
3. insert the created string in another table.
by trying this dynamically for any table i run in the following two issues:
1. creation of a rowtype needs the tabletype
2. no iterating over rowtype possible
are their any ideas to solve this issue. or do i have to write a procedure for every table i use.
regards,
rené

You can do it with a single, generic procedure using DBMS_SQL.

Dynamic binding for table column

Hi,
I am using standard application and in a table (not ALV) i want to chnage the name of a column. Already a OTR is placed in it so am planning to do a dynamic bind for the text in the header. Kindly suggest ways.
Thanks,

Problem with adf table when adding component in table column.

Hi All,
i am using jdev version 11.1.1.5.0.
use case: i have created one adf table which is based on DC VO. now i have added one select one radio group component(which contain 4 radio button approved ,reject,back,None) in adf table.
table have many rows for example in first row i have select approved and to next row i have select reject now when i get value of radio group in backing bean using component binding i got last selected value.(in that case reject).
And second is that when i set radio button value for current row using binding like
rb.setValue("R") then reject option selected for all rows.
so my question is that-
how can i get and set value of select one radio group in row level using component binding.

Hi,
I don't see a reason for not using a transient attribute for the radioGroup in your previous reply.
Here is the example i tried.
                        <af:selectOneRadio label="#{bindings.DeptView1.hints.DeptnoRadio.label}" id="sor1"
                                value="#{row.bindings.DeptnoRadio.inputValue}">
                            <af:selectItem label="A" value="A" id="si1"/>
                            <af:selectItem label="B" value="B" id="si2"/>
                            <af:selectItem label="C" value="C" id="si3"/>
                            <af:selectItem label="D" value="D" id="si4"/>
                            <af:selectItem label="E" value="E" id="si5" disabled="#{row.bindings.EnableDisable.inputValue}"/>
                        </af:selectOneRadio>Where DeptnoRadio is the transient attribute i've created (which will have some random values between A and E), and EnableDisable is another transient variable of boolean type which would return true or false based on some condition.
Now, for every row, the value is different (and corresponding radio button is selected) and for a row, which matches the condition, the option E is disabled.

Open a Dynamic URL from a Table column link

Hi,
Jdev Version (11.1.1.6.0)
I have requirement to open a dynamic URL from table column. Any time I click on link, it should generate dynamic URL based on column attribute and open in popup or browser. Can someone pls suggest how to achieve this.
Thanks
Ank

1)If you have any parameters that needs to be passed to build that dynamicURL, just set a propertyListener on the column attribute and get the value.
2)Then on the af:commandLink action, build your dynamicURL with the required parameters.
3) If you URL is all together a different application which doesn't share your transaction, you can open it as below
In the below code, urlWithParams will be your dynamicURL.
ExtendedRenderKitService erks =
Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
StringBuilder sbURL = new StringBuilder();
sbURL.append("window.open(\"" + urlWithParams + "\");");
erks.addScript(facesContext, sbURL.toString());
You can also try the above response by user 948181.
Hope it helps.

Dynamically changing the Advance table column Header.

Dear All,
I want to change dynamically the Advance table column header.
I tried the below code and its working process request,not in process form request when button pressing.
Please suggest me.
         OAAdvancedTableBean tableBean =
                           (OAAdvancedTableBean)webBean.findIndexedChildRecursive("advanceTableRN");
                       if (tableBean != null) {
                       System.out.println("tableBean");
                           OAColumnBean columnBean =
                               (OAColumnBean)tableBean.findIndexedChildRecursive("column3");
                           if (columnBean != null) {
                               System.out.println("columnBean");
                               OASortableHeaderBean colHeaderBean =
                                   (OASortableHeaderBean)columnBean.getColumnHeader();
                               if (colHeaderBean != null) {
                                   System.out.println("colHeaderBean");
                                   colHeaderBean.setText("Segment3");

You can try 2 options:
1. Try to call pageContext.forwardImmediatlytoCurrentPage();
2. Try yo set a vo attribute to the columnbean text property and set the vo attribute programmatically. (I have not tried this but I think it should work)

Nested Composite Component Doesn't work for table column

I have reported this issue as defect 1541 but I'm hoping someone my have a suggestion on a work around for this. Here is the issue
I am attempting to use composites to represent a table column. I have tried this with both IceFaces and the standard implementation. I have a custom component that is of type UIColumn that is being inserted into another composite that houses a table. The table renders and the column renders. However, the outputText that should represent the row data does not render. Interestingly this will render using composites when I don't have the column rendering as a composite (IE the table is contained in the composite and the row level output is contained in the top level page.). That is not my requirement though. This seems to be a tough cookie to crack. I have the source now and am starting to acquaint myself with it in an attempt to figure out what is going on. Any brilliant ideas out there?
Code is below.

Hi,
I recall an issue in 10.1.3.2 with inner frames that had the wrong JavaScript reference to the DOM. So I assume this to be the same in your case. So you can give it a try with JDeveloper 10.1.3.3 and see if this fixes the problem

Dynamic table columns...

hi there,
i have a table on my webdynpro with several columns displaying values in EUR with 2 decimals.
now my customer wants to be able to switch between EUR and Thousand-EUR. When Thousand-EUR is displayed ther should be no decimals visible anymore. How can i achieve that? in my context-node the values are defined with 2 decimals. is it possible to change types of context-attributes dynamically? or is there another way to achieve that.

Hi,
Suppose ur text view element ID contained in a particular table column is 'TXT_VIEW_AMOUNT'.
then you get its reference like this in domodifvview
data: lo_text_view type ref to cl_Wd_text_view.
lo_text_view ?= view->get_element( 'TXT_VIEW_AMOUNT' ).
then call the corresponding bind_text method
lo_text_view->bind_text( path = 'DATA.AMOUNT ). "here DATA.PATH is attribute path
Hope this helps

SQL from Table Column with Dynamic URL Problem

This is the SQL I'm attempting to save to a table column via the Object Browser;
select
"a"."PBR_BRIEF_ID" "Brief ID",
"a"."PROJECT_NUMBER" "Project",
"b"."DESCRIPTION" "Description",
"b"."ACTUAL_END_DATE" "Actual End",
"b"."RFS_DATE" "RFS",
"b"."LOCATION_CODE" "Location",
''||"b"."ESA_CODE"||'' "ESA",
"b"."PROJECT_USER_STATUS" "Status",
"b"."PROJECT_TRIGGER" "Trigger"
from
UPT1TRIAL.FUND_PLAN_BRIEF_LINK_CCR@NDSD "a",
UPT1INTEGRAL.INT_PROJECT_DATA@NDSD "b"
where
"a"."PBR_BRIEF_ID" = :P3_BRIEF_ID and
"a"."PROJECT_NUMBER" = "b"."PROJECT_DEFINITION_NUMBER"
The intesting bit is the following, where a URL is return behind a particular column;
''||"b"."ESA_CODE"||'' "ESA",
It's interesting because when I click on "Apply Changes" in the Object Browser, the text that appears in the column is as follows, i.e. with APP_ID and SESSION populated;
''||"b"."ESA_CODE"||'' "ESA",
Why would that happen??
The full SQL above is used in an application page with a SQL Query (PL/SQL function body returning SQL query). The basic SQL works OK but because of what the Object Browser is doing, the link does not.

Damian,
Use
& lt;
for your < tags and then the message will appear in the proper format.
If you are using dynamic sql to generate an url with APP_ID and SESSSION you could:
a) create page items (P1_APP_ID and P1_SESSION)
b) compute those page items to the actual APP_ID and SESSION_ID
c) use the value of those items while generating your dynamic sql (instead of APP_ID and SESSION)
Then, your links will show the right APP_ID and the right SESSION.

Dynamic table column creation

Hi All,
I am trying to create a table where the number of columns is equal to the number of entries in an output table in my context. How do I go about creating columns dynamically dependant on the number of entries in a table?
Kind regards
Seb

If you really need to create table columns programmatically, you can do this in the wdDoModifyView() method of the view controller.
Store the configuration data for the columns in the view controller context and write some code like the following:
private static void addColumn(IWDTable table, String id, String attributeName)
IWDTableColumn column = (IWDTableColumn)
    table.getView().createElement(IWDTableColumn.class, id);
IWDInputField editor = (IWDInputField)
    table.getView().createElement(IWDInputField.class, null);
column.setTableCellEditor(editor);
editor.bindValue(attributeName);
table.addColumn(column);
public static void wdDoModifyView(
IPrivateXYZView wdThis,
IPrivateXYZView.IContextNode wdContext,
com.sap.tc.webdynpro.progmodel.api.IWDView view,
boolean firstTime)
//@@begin wdDoModifyView
if (<table needs to be recreated>)
    IWDTable table = (IWDTable)
      view.getElement(<tableID>);
    table.destroyAllColumns();
    addColumn(table, "columnA", "attributeA");
    // etc.
//@@end
This assumes you have created the table itself during design time and bound its data source already. If needed, this can also be done programmatically.

Dynamic table column editing

Hi,
I made a VO with quite complex query (nested subqueries linked with inner join) and when I dragged it from Data Control to the page I didn't get the familiar context menu with implementation options I used to get it earlier.
Instead of, I got an implemented table with following structure:
- af:table - t3
- af:forEach
- af:column - #{...}
- af:outputText - #{...}
Did I get a dynamic table?
My problem is that I cannot get the list of attributes from VO query and then to edit table columns.
They are shown in table at runtime but with default properties. I can set up af:column options generally but I need to set up all of the attributes individually.
Is this a query-level problem or there is another way doing this?

Aleksandar Čkrebo

Dynamic entry list used in a table column

On a form, we noticed a dynamic entry list will limit which values a user may enter by validating against the entry list values. We need to have the same validation occur when a dynamic entry list is used in a table column. Has anyone had success in getting the dynamic entry list to validate the cell values in a table column?

Hey Dan,
You are right.... Its a bug... we are also using VC CE 7.1 SP 05....
When I try in form (with combo box) its working fine...I mean its giving error saying "Character string "4" does not exist in the allowed set of values and its not forwarding any values...
but when I use it in table, its not giving any error.
I saw some demos where it was working fine... but those are older sp versions of CE 7.1...
Try to contact SAP VC team on this....

How to create table columns dynamically ?

Hi All,
I am working on an SSRS report that will show sales in the past 5 years. If the user selected to view sales of past 3 years he will only see 3 columns. so How can I create table columns dynamically at run time and how can I make sure that their dimensions
will adjust to fit the report page size.

Hi Developer life,
According to your description that you want to dynamically increase and decrease the numbers of the columns in the table, right?
As Jason A Long mentioned that we can use the matrix to do this and put the year field in the column group, amount fields(Numric values) in the details, add an filter to filter the data base on this column group, but if
the data in the DB not suitable to add to the matrix directly, you can use the unpivot function to turn the column name of year to a single row and then you can add it in the column group.
If there are too many columns in the column group, it will fit the page size automatically and display the extra columns in the next page.

If your still have any problem, please try to provide us more details information, such as the data structure in the DB and the table structure you are currently designing.
Any question, please feel free to let me know.
