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?

How can I automatically refresh a Web Dynpro App every 5 minutes

Hello,
I have a web dynpro that is calling a web service. I need that this web dynpro app auto-refresh (recall the web service and update the information) without any user interaction every 5 minutes.
How can I do this?
Thanks & Regards
SU

you can use timedtrigger UI element to achieve it.

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.

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 !

Web Dynpro application needs to never expire.

Hi
I have a Web Dynpro application (NW2004 SP12) that displays spreadsheet like sales data to anyone who walks past the screen in a common area in the office/s. It should therefore run unattended. It refreshes the data on a timer. The data comes from a back-end aRFC. Everything works fine but about every 1.5 days the application times out (session expires) and needs to be re-opened (this seems to be a large administrative problem to re-login at all the deployment sites).
It gives an error 500application has expired. Please restart with the refresh button
In testing/troubleshooting I used the direct URL to the application running on WAS and not through a Portal iView.
I also changed the System destination from using SSO to using a dedicated user to the back-end.
Does anyone have an idea on how to auto refresh a Web Dynpro application or auto-renew the session so that it can run forever or a way to re-login automatically?
Thanks in advance,
Rick Viljoen

Hi Isidro
Yes, this was my final solution. Here is the code for the htm page. It will refresh/reload every 6 hours. Hope it helps.

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

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,

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,

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<i>.fieldname = $.rawValue
xfa.host.messageBox($record.rootnodename.tablenodename.data<i>.fieldname)

Clear/refresh(F5) fields in web dynpro application view

How to clear or refresh(F5) fields in web dynpro application abap while redirecting to another view? I have tried using "context_node->invalidate()" but it's not working for all the fields, some are getting initialised and some not. Is there any other method to refresh all the fields in the view all at once. Please guide.

Hi,
For the Context node( to which the drop down is bound) create a supply function as shown below:
Now populate the drop down in supply function method instead of WDDOINIT method.
Go to methods tab and write the below code in supply function method:
DATA lo_nd_drop TYPE REF TO if_wd_context_node.
    DATA lt_drop TYPE wd_this->elements_drop.
    DATA ls_drop TYPE wd_this->element_drop.
*Fill Drop down
    ls_drop-val = 'ABC'.
    APPEND ls_drop to lt_drop.
    ls_drop-val = 'DEF'.
    APPEND ls_drop to lt_drop.
* bind all the elements
   node->bind_table(
     new_items            = lt_drop
     set_initial_elements = abap_true ).
Now once you call invalidate( ) the drop down will automatically be initialized( since the supply function will be called again) And you don't have to write the code again to populate the drop down.
hope it's clear now.

Kiran

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).

Raju,
Please clarify this.
Do you have a method clear_info_refresh_visible in your component controller. I think not.
I am not able to relate your request and coding.
You can simply clear the internal table like this
clear lt_intern_tab[].
If it is a context node then you can bind a empty table to the node to make it empty.
lo_nd_data->bind_table(
     new_items            =   lt_intern_tab
     set_initial_elements = abap_true ).

Dynamic selection screen with ABAP web dynpro

Hi all.
    How can I create dynamic selection screen with ABAP web dynpro? Thank you in advance.

hi yinglak.....
         this is possible........ all the ui elelments has the property called visible and enabled.... just assign an attribute of type wdui_visibility to the visible property....
in the wddomodify method..... check for the radio button value and pass the value true or false to this attribute and it gets changed automatically.
