How to dynamically create a JSF dataTable from a String[][] array

Hi, I�m developing an application that uses columns, rows and data instead of any other attributes, so I got from a database Resultset a String[] array with the rows headers, other String[] array with the columns headers, and a String[][] array with the information between every row[] and column[] header al this String arrays depend on a method that receives the group title as a parameter so they are dynamically created, anyway I can display this information in a jsp page but I don�t know how to display this information in a JSF dataTable.
Does anybody knows how I could do this? and which is the proper way to create a dynamically rows and columns dataTable?

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,

Adding AJAX support for dynamically created panelGrid components

Hi everyone!
I would like to ask help from anyone who may have encountered similar problem before...
I have a panelGrid whose component is dynamically created by the backing bean. Here is my JSF code:
<h:panelGrid styleClass="panelGrid"
          rowClasses="tsPanelGridRowClass" columns="8" cellpadding="0"
          cellspacing="2" bgcolor="transparent" style="margin-left: 10px"
          id="revCenterItemPanelGrid"
          binding="#{pc_Touchscreen_pull_select_item.revCenterItemPanelGrid}">
</h:panelGrid>And here is the code for backing bean that adds content inside the panelGrid:
HtmlOutputText index = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
index.setId("1");
index.setValue(String.valueOf(1));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);On click of a button...

index.setId("2");
index.setValue(String.valueOf(2));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);
}However, update doesn't seem to work. I have been successful in adding ajax support to a panelGrid that is not dynamically created but not for this one.
Has anyone encountered this error before? Any ideas?
Thanks in advance!

Dynamically create a SelectOneMenu

Hi All,
I have a JSF page on which I need to dynamically create and bind a SelectOneMenu. In order to do this I have the following code (all in a request-scoped bean used by the JSF page):
List<SelectItem> values;
// Called after a button is clicked on the page
public void createMenu() {
    values = new Vector<SelectItem>();
    // Load the values to be displayed
    HtmlSelectOneMenu menu = new HtmlSelectOneMenu();
    menu.add(items);
    UISelectItems items = new UISelectItems();
    ValueExpression expr = // Get ValueExpression pointing to this request-scoped bean's 'values' attribute
    items.setValue("value", expr);
    // Create the SelectOneMenu inside a binded panel on the screen
    getCustomPanel().getChildren().add(menu);
public List<SelectItem> getValues() {
    return values;
}This works fine and the SelectOneMenu is displayed correctly and contains the correct values. However, as soon as I perform any type of postback (navigation, clicking on buttons/links on the page), I receive the following exception:

|#]I tried adding breakpoints to all my getters and setters and the constructor of the request-scoped bean, and as they are never triggered I assume this exception occurs before my code is actually accessed. As far as I can tell, for some reason, on creating a postback the value binding of the UISelectItems component is null and as such it can't find the SelectItems it needs. I don't know why this is or how to fix it, though. This doesn't happen if the component isn't created dynamically, and unfortunately our business requirements are as such that I have to create it dynamically.
Your help would be much appreciated as this really got me stumped and I really need this functionality to be in the project.
Thank you,

Dynamically created HTMLDataTable does not update its chlidren

I have a very delicate problem that I hope to get help with. I have created a HTML data table dynamically in the Java code. The left-most column contains a checkbox so that I can select and deselect rows in the table. The problem is that the checkbox value is only read from my backing bean but changes to it are not written back.
The strange thing is that if I create exactly the same data table statically (i.e., as tags in the JSP-page) everything works perfectly fine.
Is there some strange property that needs to be set when creating the data table dynamically that the JSF-framework automatically sets when it creates the table from the tags?
Below you see the code for the creation:
HtmlDataTable component = new HtmlDataTable() ;
CColumnHeader   column;
UIColumn        tableColumn;
tableColumn = new UIColumn();
HtmlOutputText textHeader = new HtmlOutputText() ;
textHeader.setValue("");
tableColumn.setHeader(textHeader);
HtmlSelectBooleanCheckbox tCheckBox = new HtmlSelectBooleanCheckbox() ;
tCheckBox.setValueBinding( "value", FacesContext.getCurrentInstance().getApplication().createValueBinding("#{data.subItems[0].selected}")) ;
tableColumn.getChildren().add( tCheckBox ) ;
component.getChildren().addAll( this.uicolumns ) ;
JSF tag is defined as...
<h:dataTable id="table" value="#{bean.model}" binding="#{bean.component}" var="data" />This do not work!
However, the below code do...
<h:dataTable id="table2" value="#{bean.model}" var="data">
<h:column >
<f:facet name="header">
     <h:outputText value="" />
</f:facet>
<h:selectBooleanCheckbox value="#{data.subItems[0].selected}" />
</h:column>
</h:dataTable>          For what I know these to examples should be equivalent.
Furthermore, I noticed in the debugger that the attributes of my dynamically created table was not the same as the attributes on the one that JSF created for me. For example, each component that JSF created has got a map entry with the key javax.faces.webapp.COMPONENT_IDS for a ListArray containing the ids of its children. However if I try set this attribute in my code the column is not rendered at all. The UIColumn in the JSF-created table did have a javax.faces.webapp.FACET_NAMES=[header] in its attribute map. I don�t know if this has something to do with it, it was just one thing I noticed.
Is this a bug or am I missing something?

Why is that?
What is it that actually goes wrong here? The two example works
exactly the same in every aspect but in the first example, the JSF-
framework only calls the getter method of the selected property and the
latter case it calls both the getter and the setter. Otherwise the two
tables works correctly.
I use the binding attribute to be able to create the HtmlDataTable
before the actual page is loaded and dynamically populate it with
different numbers of columns depending on different system states.
This is the reason why I have to create it dynamically and why I have to
use the binding attribute.
What is the reason for this not working? Am I breaking anything in the
specification?
What do you mean by "...with the hope that JSF will draw.."? It's is
drawn, it is just the setter method that is not beeing invoked correctly.

Dynamically Create Image: RDataMatrix

Hello All,
Anyone know of any samples or tutorials showing how to dynamically create images on a web page using RDataMatrix? The library can be found at java4less.com. Any input would be greatly appreciated.
Thanks,

Hi,
I am not aware of this. However, we have examples posted in blogs and referenced here that use a servlet URL reference from the image objec in JSF to access streamed image contents

Dynamically create dataTable

Hi,
I need to know if it's possible to dynamically create a jsf data table and populate it with values from an ArrayList at runtime. I already have the array list but I won't know it's dimensions until runtime because the queries that fill the arrayList will be custom selected by the user. Can anyone pls help me? If you need any more information or any code I'll be glad to provide it.
Thanks.

Use value binding, or method binding, for its rows attribute value. Other attributes may serve parts of your specific needs. -- Or, depending on your use-case scenario, simple value binding for its value attribute might suffice.

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:
DATA:
    l_view_controller_api TYPE REF TO if_wd_view_controller.
l_view_controller_api = wd_this->wd_get_api( ).
TRY.
      CALL METHOD l_view_controller_api->if_wd_navigation_services_new~prepare_dynamic_navigation
        EXPORTING
          source_window_name        = 'WDW_MAIN'
          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'
        RECEIVING
          repository_handle         = wd_this->g_rep_handle.
    CATCH cx_wd_runtime_repository .
ENDTRY.
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:
DATA:
    lv_position           TYPE string,
    l_view_controller_api TYPE REF TO if_wd_view_controller,
    lr_view_usage         TYPE REF TO if_wd_rr_view_usage,
    lr_view_***_t         TYPE wdrr_vca_objects,
    lr_view_***           LIKE LINE OF lr_view_***_t.
l_view_controller_api = wd_this->wd_get_api( ).
lr_view_usage = wd_this->g_view->get_view_usage( ).
lr_view_usage->delete_all_navigation_targets( plug_name = 'TO_VW_CONTENT' ).
CLEAR lv_position.
CONCATENATE 'VW_MAIN/VC_TAB.VW_SUB/' old_tab '_VC' INTO lv_position.
TRY.
      l_view_controller_api->if_wd_navigation_services_new~do_dynamic_navigation(
      source_window_name = 'WDW_MAIN'
      source_vusage_name = 'VW_SUB_USAGE_1'
      source_plug_name   = 'TO_EMPTYVIEW'
      target_component_name = 'ZTEST_DYNAMIC'
      target_view_name   = 'EMPTYVIEW'
      target_plug_name   = 'DEFAULT'
      target_embedding_position = lv_position ).
    CATCH cx_wd_runtime_repository.
ENDTRY.
CLEAR lv_position.
CONCATENATE 'VW_MAIN/VC_TAB.VW_SUB/' tab '_VC' INTO lv_position.
TRY.
      wd_this->g_rep_handle = l_view_controller_api->if_wd_navigation_services_new~prepare_dynamic_navigation(
        source_window_name = 'WDW_MAIN'
        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 = lv_position ).
    CATCH cx_wd_runtime_repository.
ENDTRY.
wd_this->fire_to_vw_content_plg( param1 = tab ).
Ann.: I my example, I had 3 views: VW_MAIN which embedds VW_SUB. VW_SUB has the tabs in it and VW_SUB embedds VW_CONTENT.

Is there a way to use a statically defined appearance stream in a dynamically created annotation?

Hello,
I want to create a document with cascading 'popups'. Not the built-in text-only popup, but an annotation containing an appearance stream that defines text and images. I'm currently using widget annotations based on a pushbutton field.
Each page in my document has many citations that refer to other pages in the document. When a user hovers over the citation, I want a 'popup' to appear containing a depiction of the destination. However, as the destination will itself have citations, I also want the 'popup' to contain citations that the user can hover over, triggering another popup, etc. In this way, a user could navigate throughout the document without leaving the page or even clicking the mouse.
Obviously, with even a modest number of citations per page, pre-calculating and statically defining all of these widgets causes a combinatorial explosion, making the document sluggish and very large.
Instead, I'd like to statically define appearance streams once per document, and then dynamically create annotations and assign the appropriate appearance stream using JS as the user navigates.
So far I've created a named AP in the names dictionary, but I haven't been able to use it to dynamically set an appearance stream of a dynamically created widget annotation.
Also, I've called Doc.getIcon(), passing in the named AP, which returns an Icon object. However, after field.buttonSetIcon() and passing in the named AP, the button does not display the icon.
Is there a way to use a statically defined appearance stream in a dynamically created annotation?
Thank you,
Dave

Hi George, I've gotten named APs to work, and I expect hidden buttons will follow. Thank you very much!
Quick follow-up - I will have many documents embedded within the same pdf file, and some of these documents will contain identical popups. However, I don't want to store identical icons in each document on account of file size.
Instead, I'd like to store one instance of each icon for all documents in the file.
Can I store all of the icons in a single document, and then access them by calling <DocName>.getField().getIcon() from any document in the file?
Thank you again,
Dave

How to get the co-ordinates of a dynamically created input field

Hello Frn's
i have created a dynamic text view . but this text view is not appearing at proper position . I want palce it infront of a dynamically created input field . how can i do this ?
as i am thinking ...i should first of all get info about the co-ordinates of dynamaclly creatd input field . and with respect to these co-ordinates ...set the position of text View .
Please suggest your thoughts .
Thanks and Regards
Priyank Dixit

Hi,
There is no provision in WD for getting screen coordinates and then placing the UI element.
You to add the UI element to layout editor and based on the layout type it will add the UI element to respective position.
I would advice not to create dynamic UI elements( instead you can create them statically and then play with visibility status through context binding ). This will be more effective way and less error prone. This is also recommended practice.
still,For dynamic creation you can refer to following wiki:

How dynamically create connection pool and Datasource

Hi
How I can dynamically create a connection pool and Data source in Oracle 10g Application server. In our J2EE application the user will be login with db user name, password and database name. I want to create connection pool and data source on the fly while login the user with database name. I our application we have access approximate 80 Databases. so my approach is given bellow
1) Planning to create 80 connection pools and 80 Data sources so when user logs in while selecting the db name i will call the appropriate data source and create the DB connection. Is there any limitation to create number of data sources in oracle app server?
2) Create DB connection with out using connection pool and data source. But i am not prefer this approach coz we need to handle some transaction in our application.
Kindly throw some light on managing connection pool programmatically or in application run time.
I would really appreciate if any one can provide any links or any inormation on this issue.
Thanks in advance.

Kindly let me know is there any drawbacks to create 80 Data Sources to connect 80 database in Oracle 10G App server and each data sources should have one connection pool. so i need to create 80 connection pool. Please let me know is this right approach or any work around to create Data source on fly for each request for corresponding database.

Assigning a 'dynamically created sequence' value to a variable

in my procedure i am creating a sequence on the fly, i am preparing the name with some passed parameters like below
v_seq_name := 'seq_'||loadid||v_table_name;
execute immediate 'CREATE SEQUENCE '||v_seq_name||' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment by 1 cache 20';
and now after doing some operations i need to assign the current value of sequence to a number variable i tried following but not working
1) v_curr_value : = v_seq_name.currval ;
2) select v_seq_name||'.nextval' into v_curr_value from dual;
can you please suggest me how i can get the value in plsql block.

Having said that, your architecture is probably wrong if you are dynamically creating things in a procedure.
Why do you need to create them dynamically?

Dynamically creating a Record Group based on Previously entered Record Grou

Forms [32 Bit] Version 10.1.2.3.0 (Production)
Hi,
I know how to dynamically create a record group based on a query and putting the code in When new form instance.
My query is. I have a form which has multiple Record Groups and the user wants to dynamically create subsequent groups based on previous groups.
For example
I have a record group with selects a Location,
when the user selects the Location from a list of values
the 2nd record group called 'Cost Centres' will have to filter out only those with the locations selected above.
How can I populate the 2nd record group at run-time when I do not know what site the user will select?
If I simply populate in when new form instance as in location and just select everything, the list of values populates.
CC field is a LIST ITEM and the list style is a POP LIST, it is not required.
I have put the code in the Location field in the when-list-changed trigger.
I am getting this error:
frm-41337: cannot populate the list from the record group
here is the code:
DECLARE
v_recsql Varchar2(1000); -- The SQL for creating the Record Group.
v_recgrp RecordGroup; -- Record Group
v_status Number; -- Return Value of Populate_Group function.
c_where VARCHAR2(1000);
BEGIN
     IF :location = '1' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''02'')';
     ELSIF :location = '2' THEN
          c_where := ' substr(cost_centre,1,2) in (''02'',''03'')';
     ELSIF :location   = '3' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''11'',''07'')';
               ELSE
          c_where := ' 1=1'; --EVERYTHING
     END IF;
v_recsql := 'SELECT cost_centre, description FROM   cost_centres where '||c_where;
-- Create the Record Group
v_recgrp := CREATE_GROUP_FROM_QUERY('v_recgrp', v_recsql);
IF NOT ID_NULL(v_recgrp)
THEN -- No Error, record group has been successfully created.
-- Populate Record Group
v_status := POPULATE_GROUP('v_recgrp');
IF v_status = 0
THEN -- No Error. Record Group has been Populated.
POPULATE_LIST('block.CC', 'v_recgrp');
END IF; -- IF v_status = 0
-- Delete the Record Group as it is no longer needed.
DELETE_GROUP('v_recgrp');
END IF; -- IF NOT ID_NULL(v_recgrp)
END;thanks for your assistance.

Hi,
Once record status gets change for block you can not populate/repopulate the list item. Keep those list items as non-database item with different names and create different items as database orignal items. Than assign the values in WHEN-LIST-CHANGE trigger to the actual database items.

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.
Thanks in advance,
Harsha
