Dynamic Web Dynpro

In my application I need to capture a set of data for every day for as many days as needed, based on information already entered. In other words I do not know how many days I need to capture data for until runtime.
I need to be able to dynamically repeat the same set of data input elements for each day.
Any suggestions would be greatly appreciated.

Hi,
it's possible to generate web dynpro on the fly. You should be able to find some articles or documentation here on SDN. But why don't you use a table? You can use parameter visibleRowCount to avoid paging and disable adding/removing lines from the table. It would be easier than dynamic generation of view elements and binding them.
BTW there is a separate forum dedicated to WebDynpro for ABAP. You would have better chance to get answers for your questions there.
Cheers

Refresh dynamic web dynpro

hi all,
i have a dynamic dynpro, whit this similar structur:
a->
a1->
        a1.1
              ->a1.1.1
              ->a1.1.2
        a1.2
              ->a1.2.1
              ->a1.2.2
b->

hi,
The structure could be achieved with Recursive node.
Can you be more specific for the requirements like what you need to reload?
Can you provide example?
What will be there initially and after reload how should be the structure?

Dynamic Web Dynpro Project

Noufal,
I am working on a WD app wherein I need to dynamically populate dropdownlists, input fields. Dynamic values are contained in an object that has propertiy values such as id, text (could be a value set), read-only flag, labelid flag etc.....
My issue is depending on the UI element type (dropdownlsit, input field, checkbox etc..) I may have to populate UI element corresponingly. I do not want to yse context nodes to bind values, as I have way too many fields to populate. My question to you is as follows:
1) How do I know the type of the element ?
2) How do I populate the dropdown list ?
3) Show the view manipulation be done only in the wdDoModifyView method only ?
If you have posted code for some of my questions, please paste in your response once again....
Thanks,
Sri

Armin,
I reviewed the chapter and found it helpful. However, I am not sure if it addresses the issue of accessing the value of a node, the kind I have talked about. Example is as follows.
I have the context structure created dynamically, and it is as follows.
NodeA
NodeA1
NodeA11
Element1
Element2
Element3
NodeA2
NodeA21
Element1
Element2
Element3
NodeA3
NodeA31
Element1
Element2
Element3
One of the earlier responses to my post, I think it was by Noufal, would work if nodes were created at design time.
But noes above are created at runtime.
I have been able to access the node say NodeA11, but still not sure how to access the attribute Element1 or Element2, which ever is the selected element. Keep in mind, these elements are created dynamically, so I cannot access values with statement like
wdContext.currentNodeA11Element().getElement1();
Hope I am making sense. Do let me know how.
Thanks !

Create dynamic table in web dynpro abap

Hi Friends,
I want to create several tables in a web dynpro. For this reason I have created a View, a group1 and a context node.
Now I want create a table for each characteristic group from cabn in the ui group1.
For this reason I want to use create_table_from_node and I have to craete dynamicly attributes in the node.
Is it the propper way or is there a different approach.
So in this case
1. I read the node
2. craete attribute for each characteristic group in this node
3. create a UI Table with create_table_from_node for each attribute
4. bind the data to the UI Table
Can I do the same without to craete attributes?
Thank in advance.
RG. Jimbob

Hi Jimbob,
Have you looked at using the row-repeater UI element? You could then have as many tables as per your characteristic groups.
Although this would be more difficult if the attributes of each table were to also be only known at run-time. (I'm not sure that this is the case though from your description of the issue.)
so have a context of the form:
Context Root
--->node_characteristic_group (0..n)
>node_char_group_details(0...n) (non-singleton child node)
then bind your row repeater to node "node_characteristic_group " and bind the table inside the row repeater to node "node_char_group_details".
Each time you had a new element in the node_characteristic_group you would get a new table...
Much easier to support that anything dynamically created.
Cheers,
Chris

Dynamic insertion of MIME object into a web dynpro component

Hi,
I want to dynamically insert a MIME object of type JPEG or type GIF into my web dynpro component at runtime.
I was unable to find the database table which contains the list of MIME objects for a particular web dynpro component.
Can you please help me out with this?
Thanks in advance,
Adithya
Moderator message: wrong forum, please have a look in the "Web Dynpro ABAP" forum.

Hi Muzammil Bichoo ,
when you copy the wda component, it will be copied and will be in active state, once all the components are activated means, windows, views, everything will be available.
now create application for your component, if you have more than one window(interface view) select the one which you need for the application.

Adding rows in web dynpro ABAP Dynamic Interactive form.

Hi Experts,
I am having problem in web dynpro ABAP Dynamic Interactive form.
This is my scenario....
I have a dynamic interactive form that has buttons to add and remove rows in a table. It works fine when I preview it , but when I render, view or save it using ADS, it no longer works. The "add" button actually does instantiate more repeating rows, because I put some trace messages in to count them, but the added rows are not displayed. How do I make them visible?
In web dynpro java we write some coding in modify view to set the pdf form as dynamic
IWDInteractiveForm iForm =
(IWDInteractiveForm)view.getElement("<ID>");
iForm.setDynamicPDF(true);
simillarly what we need to write in web dynpro ABAP.
Please give me solution for the same.
Thanks,
Sathish

hi all,
expecting reply from u all. pls help me and give some sugesstion.

Reading Dynamic Table Values in interactive form (web Dynpro ABAP)

Hi All,
I have created a Web Dynpro ABAP application which contains an Interactive Form, That Adobe Interactive Form contains Dynamic table (New rows can be added manually and deleted using a button).
I am not able to read the Dynamic table values in Web Dynpro u201COn Submitu201D.
In the Adobe form I have web Dynpro native button (I am using ZCI), while clicking the native button I need to read the dynamic table values.
How can I resolve this problem.
Thanks and Regards,
Boopathi M

that means, when u add the table instance at runtime, you will also have to add an element to the node that is bound to the table.
probably addNew() mathos may be useful to you.
it appends a new record to the record set.
xfa.sourceSet.dataConnectionName.addNew()
also when on the exit event of the table field, do the following:
var i = xfa.parent.index
$record.rootnodename.tablenodename.data.fieldname = $.rawValue
xfa.host.messageBox($record.rootnodename.tablenodename.data.fieldname)

How to create the Dynamic UI element table in web dynpro in abap

Hi All,
Does anybody have reference note or teach me how to create dynamic UI element table in web dynpro in abap ?
Regards,
Luke

HI LukeWong ,
for creating any UI dynamically you shoul use their runtime class that always start with cl_wd_* ui element name*
so for the Table UI element the runtime class is CL_WD_TABLE
now reffer the below code for creating the Table UI dynamically
METHOD wddomodifyview.
DATA lr_table TYPE REF TO cl_wd_table.
DATA lr_flow_data TYPE REF TO cl_wd_flow_data.
DATA lr_container TYPE REF TO cl_wd_uielement_container.
DATA lr_column_name TYPE REF TO cl_wd_table_column.
DATA lr_text_view TYPE REF TO cl_wd_text_view.
DATA lr_table_header TYPE REF TO cl_wd_caption.
DATA lr_column_name_header TYPE REF TO cl_wd_caption.
IF first_time EQ abap_true.
lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
lr_table = cl_wd_table=>new_table(
id = 'TBL_TABLE'
bind_data_source = 'TABLE'
design = cl_wd_table=>e_design-alternating
visible_row_count = 3
lr_flow_data = cl_wd_flow_data=>new_flow_data( element =
lr_table ).
lr_container->add_child( lr_table ).
lr_column_name = cl_wd_table_column=>new_table_column(
id = 'TBL_EXAMPLE_NAME'
lr_table_header ?= cl_wd_caption=>new_caption( text = 'Table UI elem
ent - example').
lr_table->add_column( the_column = lr_column_name ).
lr_table->set_header( lr_table_header ).
lr_text_view = cl_wd_text_view=>new_text_view(
id = 'TXV_NAME'
bind_text = 'TABLE.NAME'
lr_column_name_header ?= cl_wd_caption=>new_caption( text = 'Name').
lr_column_name->set_table_cell_editor( the_table_cell_editor = lr_text_view).
lr_column_name->set_header( lr_column_name_header ).
ENDIF.
ENDMETHOD.

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Hi everyone, I have a question if is possible to create a table dynamically in Web Dynpro Java?, depending of the RFC consults create the rows dynamically, ,this table must have diferent type of columns, for example link column (when the user click this link execute an action and show a adobe interactive form in another view), image column (show an image depending of the information)
Thank you everyone
Atte Israel

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,
Constantine

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

Path to (dynamic) image files on the WAS Server - Web Dynpro

Hello again with a new question ...
I wrote a Web Dynpro Application, that uploads images from the client and stores them in a directory on the server. In the next step the WD Application reads the contents of that directory (for Example 1.jpg, 2.jpg, 3.jpg) and shall display these pics (dynamically).
The only thing that does not work is displaying the images. I do not know how to address them; i simply can not see them.
My application is running on a windows host in path "E:\usr\sap..."
The Pics are uploaded into the server directory "E:\ZZZ\"
Following code shows the pics, when i use a browser on the server itself. When i try it from another machine, is doesn't work. Seems as if the supplied path is a local path, not a server path.
IWDImage image11 = (IWDImage) view.createElement(IWDImage.class, "TestBild" + i);
image11.setAlt("file:///" + files.toString());
image11.setSource("file:///" + files.toString());
// files.toString() contains: \E:ZZZ1.jpg
theGroup.addChild(image11);
Thank you !!

Armin, thank you, just solved the problem
I found a post telling something about HTTP aliases and this weblog
/people/renjith.andrews/blog/2005/03/31/creating-an-http-alias-in-was
So i created an alias (ZZZ for Hard drive directory "E:\ZZZ") and use it in the code for example:
image11.setAlt("http://netweaver:50000/ZZZ/0000009502_0002000197_2_002.jpg");
image11.setSource("http://netweaver:50000/ZZZ/0000009502_0002000197_2_002.jpg");
Now i see the images within my WDView

Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.
