How to call the task flow one region from another region?

I have page with 3 regions (column wise) named as start, center, end.
currently I having task flow for middle(i.e, center) region which have panelCollection to perform view, create, & delete functions.
Task flow:-
From(action)To
View(create)Create
Create(Done)Execute (Execute is a method call)
Execute(*)View
View(self)Execute
By press create button on Center page, task flow takes to the Create page(in Centre region) but all other regions(start, end) remains same.
I have a usecase where we have a commandLink on Start region to show the View page on Center region. but it is not able to achieve when we move to Create/Edit page.
Plz help me out to built the same.
Thanq
KSB

Hi!
First, I'm not sure that your page layout is adequate. The regions are not intended to be navigated from outside. Yet, they can send navigation action to the container (page on which the region is placed) through Parent Action taskflow element. Also, you can investigate Contextual Events that can be raised by region, but I'm also not sure that this can be easily used for cross-region navigation.
I would suggest you to reconsider you page layout. You can use dynamic regions (which are populated by taskflow based on menu selection or click on actionLink or s button). This way, in the Start facet you place a navigation menu (links), which are connected with dynamic region in Center. If you want to reuse a navigation links (in Start), you can put all this in page template and reuse it over and over again.

How can i access all the objects of one schema from another schema

Dear All,
How can i access all the objects(Tables,Views,Triggers,Procedures,Functions,Packages etc..) and do the modifications of one schema from another schema (Without using synonyms concept).
Thanks in advance,
Mahi

First of all, synonyms only help you easy reference the object. It doesn't have any implication of object privilege.
As long as you have proper privilege on target object. You can access it with or without synonyms.
Assuming you have proper privilege of objects, you can use following command to assume schema owner.
ALTER SESSION SET CURRENT_SCHEMA = Schema_owner

Two pages reuse a task flow -------how to reinitialize the task flow?

Hi, i get a question.
In general:
In the navigation menu i have two commandlink that are "Service" and "Application". And when i click on each of the two command links, i go to a page.
The detail:
This two commandlinks use a same task flow-----that is : <af:commandNavigationItem...... definition of this two link' action attributes are just the same.
What's more, the pages that i go to when i click on the link also use the same one, just show something different bansed on the paramaters when alick on the link. The parameters are defined in the <af:commandNavigationItem...... using <af:setPropertyListener..
And the question is:
when i click on the "Service" link and see the "Add service" page and then click "Application" it's still the "Add service" page, and otherwise is the same. i just can not jump freely through this tow link.
I have debuged the code and find that, once i click "Service" link then i click "Application" link, the task flow won't reinitialize.
Any one has some solutions?
Thanks in advance.

Reading the official doc will help.

How to call the show method of Popup from backing bean?

Hi!
I wanted to display the results of a search form in a dialog that is placed in popup.
That is The content of the popup will be rendered from the backing bean, dynamically .
And so when the form is filled and the submit button is clicked, the form fields have to be submitted to the server, and the results are to be displayed in the dialog,after the PPR response has arrived, and not at the time of calling the PPR.
Could you explain How this can be achieved?
Samba

Samba,
The fix for the popup in a template is to give the template an id say "template" and reference the popup in the JavaScript as "template:popupId", where popupId is the value of the af:popup's id attribute.
Regarding DWR, Joe really did a nice job with this framework. I have to say he got my attention. The one issue though is that JavaScript is an absolute must when using DWR and other frameworks that have a heavy JavaScript tilt. Dealing with JS can be a bit of a hassle due to x-browser idionsyncrascies as well as slow exection of JS. That said I believe Joe has one of the best JS solutions around.
On the flip side of this ADF Faces is trying to do something a bit different. Firstly, we want to avoid JS. The user should handle as little as JS as possible. In addition,
ADF Faces has the benefit of a server-side component framework we want to leverage this to make sure there is a limited amount of JS execution on the client.
So if you want to work with JS, DWR is a good solution. If you want to work with, Java, standards, and a great tooling environement ADF Faces is a better choice.
Finally, "Reverse AJAX" is a marketing term for "Push". You probably have also heard the term Comet. There are some varations on the protocols used but all-in- all. We are talking about one thing, the ability for the server to "Push" information to the client. Luckily, we provide this ability in a feature called active data channels. You will see this feature in the next preview. By setting an attribute value in a pageDef trees, tables, and BAM components can recieve data from the server via "Push".

How to access the datagrid in one mxml in another component

I have a datagrid in a.mxml. when click on the add button, it comes to a b.as file (not a class) to do some things and then, b.as call a popupwindow (c.mxml) to add a row into table (call backend). After I added the row to database table successfully, I want to add the row into datagrid to display, but I could not access the datagrid in a.mxml from c.mxml. How can I do this?
Thank you in advance.

If this post answers your question or helps, please mark it as such.
To add a row to the DataGrid you really need to just add data to the dataProvider collection object.
You can access components by going through the main app:
mx.core.Application.application.myA.myVar = myC.cVar;
But you should really be using custom events to communicate between components, though it is more complex. Here is my Flex 3 Cookbook post of the topic of custom events:

How to copy the data of one node to another of the same context

hi experts,
 i need to copy the data of one node to the other node of the same context.
the source node is a model node ( i.e comming from RFC ) and the destination node is a value node which i have creted.
what i have done is.
i have read the source node using wizard
do.
elem_t_p0591 = node_t_p0591->get_element(
 index = sy-index ).
 IF ( elem_t_p0591 IS INITIAL ).
 EXIT.
 ENDIF.
elem_t_p0591->get_static_attributes(
 IMPORTING
 static_attributes = stru_t_p0591 ).
IF stru_t_p0591 IS NOT INITIAL.
 wa_p0591 = stru_t_p0591.
 APPEND wa_p0591 TO itab_p0591.
 ENDIF.
ENDDO.
and then i am trying to read the destination node so the tha data i have got by above method can be binded to the destination node.
but when i am trying to get the child node it is giving me a dump saying that
'Access via 'NULL' object reference not possible' i understand this because when i debug my value node is becoming initial, and when i am trying to access the destination node using this initial node it will give me a dump,
but what is the work aroud for this.
Plz help.
Regards,
Santosh.

Hi Santosh,
 I tried replicating your behaviour in my system. This is what my context structure looks like:
Node_Test (c-> 0:n)
Name(attribute)
Node_Test2 (c-> 0:1)
 Name2(attribute)
Now when i try to access Node_Test2 then it returns me (initial) i.e. no reference and i believe the reason is that my parent node, Node_Test, is of type table( because of the cardinality) so I am expected to perform an operation on my sub node, Node_Test2, based on the node i have selected, or have specified via index .. 1 is taken by default, in Node_Test.. which in WDDOINIT is initial as i havent got access to my view yet.. so instead what you can do is bind data to your parent node, relevant data ofcourse, and then bind the recieved data to your child node i.e. Node3.
I am pasting the code here for your reference :
method WDDOINIT .
 DATA:
 node_test TYPE REF TO if_wd_context_node,
 elem_test TYPE REF TO if_wd_context_element,
 stru_test TYPE wd_this->element_test ,
 lt_table LIKE TABLE OF stru_test,
 item_test_1 LIKE stru_test-test_1.
 navigate from <CONTEXT> to <TEST> via lead selection
 node_test = wd_context->get_child_node( name = wd_this->wdctx_test ).
 @TODO handle not set lead selection
 IF ( node_test IS INITIAL ).
 ENDIF.
 get element via lead selection
 elem_test = node_test->get_element( ).
 @TODO handle not set lead selection
 IF ( elem_test IS INITIAL ).
 ENDIF.
stru_test-test_1 = 'Anoop'.
APPEND stru_test to lt_table.
stru_test-test_1 = 'Avi'.
APPEND stru_test to lt_table.
stru_test-test_1 = 'Sid'.
APPEND stru_test to lt_table.
CALL METHOD node_test->bind_table
EXPORTING
 new_items = lt_table
 set_initial_elements = ABAP_TRUE
 index =
 DATA:
 node_t2 TYPE REF TO if_wd_context_node,
 elem_t2 TYPE REF TO if_wd_context_element,
 stru_t2 TYPE wd_this->element_t2 ,
 item_t2_1 LIKE stru_t2-t2_1.
 navigate from <CONTEXT> to <TEST> via lead selection
 node_test = wd_context->get_child_node( name = wd_this->wdctx_test ).
 @TODO handle not set lead selection
 IF ( node_test IS INITIAL ).
 ENDIF.
* navigate from <TEST> to <T2> via lead selection
 node_t2 = node_test->get_child_node( name = wd_this->wdctx_t2 ).
* alternative navigation via index
 Node_T2 = Node_Test->get_Child_Node(
 Name = `T2` Index = 1 ).
 @TODO handle non existant child
 if ( Node_T2 is initial ).
 endif.
 get element via lead selection
 elem_t2 = node_t2->get_element( ).
 get single attribute
 elem_t2->get_attribute(
 EXPORTING
 name = `T2_1`
 IMPORTING
 value = item_t2_1 ).
endmethod.
I hope this helps.

How to pass the result of one script to another?

Hi
Is there any possibility to pass info from one script to another? I run some scripts at night and they have to use the results I get during the day...
Thank you in advance for any help
Vera

There's a couple of ways of doing this.
It sounds like the second script isn't being called directly from the first one, so you can't pass the data directly, so that leaves you with a couple of options.
One is to have the first script write the data to a file, then have the second script read that file.
The other would be to store the data as a property in the first script - properties are saved between executions - then have the second script read the first script's property when it starts up.
For the first option, just have the script write the data to a file:
set myData to "here's the data to save"
set myFile to (open for access file (path to home folder as text & "data.file") with write permission
write myData to myFile starting at 0
close access myFile
Now the second script can read the file:
set otherScriptsData to read file (path to home folder as text & "data.file")
For the second option, just store the data as a property:
property myData:""
set myData to "here's the data to save"
Now loading the data in the second script goes like:
set otherScript to load script file "path:to:other.scpt"
set otherScriptsData to otherScript's myData
Here you can see the second script loading the script then reading its myData property.

How to access the JTextfield on one panel from the button on the other pane

How to call BSP page in one frame from a webdynpro page in another frame?

Dear experts,
I have a scenario as follows:
A BSP application which contains 5 frames. in the first frame I am calling a web Dynpro application. This is a tree and it is displayed correctly. on click of an item (node item) in the tree, a bsp page should be displayed in the second frame. I am not able to display this in the second frame. When I call the BSP page, it is getting displayed in the same frame (i.e, the first frame).
Kindly help me out.
Thanks & Warm Regards,
Jenny

From WDA you can't force the navigation of a different frame. Nor should you really be building an application with WDA running within a frame. You will have session management problems.
SAP recommendation is to use the NetWeaver Portal. You could then place the WDA and BSP applications into separate iViews. They can communicate with each other using Portal Eventing.

How to bring the more than one rows from the table into the script

Hi
I have to bring more than one rows from the table into the Main windows of the script. so plz help me out.
Thanks in Advance
Ananya

Hi Ananya,
   Bring more than one row into main window of script.
   For this you need to do some changes for data which you pass to main window.At a time you need to pass more than one row,so for this you need to define one structure.See below code.
Types:begin of ty_rows,
     include structure (your row_structure),
     include structure (your row_sturcture),
Types:end of ty_rows.
for example....
If i need to pass 2 vendor details at a time to main window then the structure should be like this.
Types:begin of ty_rows,
       vendor1 like lfa1-lifnr,
       vendor1_name like lfa1-name1,
       vendor2 like lfa1-lifnr,
       vendor2_name like lfa1-name1,
      end of ty_rows.
Data:i_main type standard table of ty_rows,
     wa_main type ty_rows.
Based on condition you can pass more than one rows of your actual internal table data to i_main internal table.
Then you can pass i_main internal table to your main window.
    I think this will help you.
Cheers,
Bujji
