If_wd_context_node- to_xml( )

Hi experts,
I'm trying to convert some context node(s) to xml data.
But always when I call the standard method if_wd_context_node->to_xml( ) there occurs an RABAX_STATE error like this:
It doesn't matter if I call it on the root node, or on a childnode?
Any ideas?
Best regards
Volker

How to store context data in XML file in Webdynpro

Hi all
i have one typical requirement as follows.
1) i want to store context data of one view in XML file and i want to read the same data from XML into another context of View.
is there any one did this functionality then it is great help to me if they share?
Thanks

Hi,
In WD4A
Check out the mehtod in IF_WD_CONTEXT_NODE-
TO_XML returns the string about the context.

Class for IF_WD_CONTEXT_NODE

Hi Gurus,
I am new to WDA and OOPs . Some doubts
1 - Interface IF_WD_CONTEXT_NODE is implemented in which class.?
2 - What do you mean by attribute of an Interface (i.e WD_CONTEXT ) ?
     TABLE_NODE = WD_CONTEXT->GET_CHILD_NODE( 'MY_TABLE_NODE' ).--      means what ?
3 - Why do we create objects of Interfaces and not classes that implement them ?
     e.g data: TABLE_NODE type ref to IF_WD_CONTEXT_NODE.
4. Can i see the code for the CLASS that implements these INTERFACES ?
5. When and where are the objects for the classes created ?
   (as in ABAP OOPs - CREATE OBJECT <varname> ).
Help me out.
Thanks in advance.

Hi Jimmy,
Hera are some of the answers
1 - Interface IF_WD_CONTEXT_NODE is implemented in which class.?
CL_WDR_CONTEXT_NODE
2 - What do you mean by attribute of an Interface (i.e WD_CONTEXT ) ?
TABLE_NODE = WD_CONTEXT->GET_CHILD_NODE( 'MY_TABLE_NODE' ).-- means what ?
Here you are calling a method of IF_WD_CONTEXT_NODE to get a reference to a context node called as ' MY_TABLE_NODE' in your application. Once you get a refernce you can apply various operations on it. Like reading values or setting values of attributes of context node.
3 - Why do we create objects of Interfaces and not classes that implement them ?
e.g data: TABLE_NODE type ref to IF_WD_CONTEXT_NODE.
I cannot understand this question.. of course you can not create objects of the this class because it is a abstract class (reason being its non-completeness ) which therefore has this interface to use it and complete the implementation.
4. Can i see the code for the CLASS that implements these INTERFACES ?
. yes of course you can see the code.
5. When and where are the objects for the classes created ?
This are some basic of OOPS and i think you should go thru tutorials to draw this picture better.

WD_CONTEXT AND IF_WD_CONTEXT_NODE

Hi folks,
Am very new to Abap objects and working on webdynpro.I have a very basic question what is wd_context and if_wd_context_node.Please let me know what is the use of them.
Regards,
Vamshi.

Hi Vamshi,
IF_WD_CONTEXT_NODE is the reference interface of Context node, which is having so many methods for context node and attribute operations like BIND_ELEMENTS, BIND_STRUCTURE, GET_ATTRIBUTE etc.
The WD_CONTEXT attribute is a reference to the root node of the context of the controller.
See the below code, it will differentiate the two concepts.
method INVALIDATE_TABLE_NODE .
data: TABLE_NODE type ref to IF_WD_CONTEXT_NODE.
TABLE_NODE = WD_CONTEXT->GET_CHILD_NODE( 'MY_TABLE_NODE' ).
TABLE_NODE->INVALIDATE( ).
endmethod.

Regarding 'get_attribute_props_for_node'* method from if_wd_context_node

hello gurus,
                i have requirement in a view it has two radio buttons named as release and un release.if i select release button the view data in display mode only , it meaans in view one header information and one item table is there.in the second case when i select un release button the view data again in change mode.how can i achive this requirement.right now i can get the release status at runtime through radio button group by key ui element onselect action.now i need to impliment depends upon release information view data into change mode or display mode. for this can we use 'get_attribute_props_for_node' method from if_wd_context_node . if yes how can we pass parameters to this method and how can i achive my requirement through this.
i am very new for webdynpro abap .could any one suggests me on this and could any one can send sample code regarding this if possible.
thanks in advance for your reply

Hi Rajasekhar,
For ALV you have to write some code like this.. follow this
lr_column = lr_column_settings->get_column( 'FIELD' ). // Field is one field you wnat to display in edit mode..
      CREATE OBJECT lr_input_field
        EXPORTING
          value_fieldname = 'FIELD'.
      lr_input_field->set_read_only( abap_true ).
      lr_column->set_cell_editor( lr_input_field ).

Result type of get_elements of if_wd_context_node

Hello,
I need to get the internal table of a context node. I try to use the methode get_elements(), but the result type is not if_wd_context_element. What should it be? Could you give me any suggestion? Many thanks!
regards
meer

Hi , For getting the context element in to an Internal table you have to use
get_static_attributes_table method ,
Look into the Piece of code below
DATA lo_nd_series TYPE REF TO if_wd_context_node.
    DATA lt_series TYPE wd_this->Elements_series.
*   navigate from <CONTEXT> to <SERIES> via lead selection
    lo_nd_series = wd_context->get_child_node( name = wd_this->wdctx_series ).
    lo_nd_series->get_static_attributes_table( importing table = lt_series ).

How to make the text_field to editable in the adobe document?

Hi, expert,
I meet a problem when I develop a WDA. I hope to get your help. Thanks a lot. The following is my action:
Action:
1. I am using "Text Field" control rather "Text" Control in the pfd form by transfer code "sfp". I make sure in Object Palette under value tab type is : user entered - optional in the layout tab in the pfd form. The textfield is editable in the PDF preview.
2. Add the pdf forms to webdynpro application and set "sss" to the inputfield("Text Field") through context in the WDA.
3. Run the WDA. In the IE, I found the textfield in the PDF is not editable. How can I make the textfield to editable?
Whether I need change the code or others to make text_field to editable?
Do you give me some hints? Thank you very much.
The following is my code in the WDA:
method WDDOMODIFYVIEW .
********Make INTERACTIVE_FORM to editable。******
data:
lr_interactive_form type ref to cl_wd_interactive_form,
lr_method_handler type ref to if_wd_iactive_form_method_hndl.
lr_interactive_form ?= view->get_element( 'INTERACTIVE_FORM' ).
lr_method_handler ?= lr_interactive_form->_method_handler.
lr_method_handler->set_legacy_editing_enabled( abap_true ).
data:
Node_Zz_00_Test_Form_000 type ref to If_Wd_Context_Node,
Elem_Zz_00_Test_Form_000 type ref to If_Wd_Context_Element,
Stru_Zz_00_Test_Form_000 type Wd_This->Element_Zz_00_Test_Form_000 ,
Item_TEST1 like Stru_Zz_00_Test_Form_000-TEST1.
navigate from <CONTEXT> to <ZZ_00_TEST_FORM_000> via lead selection
Node_Zz_00_Test_Form_000 = wd_Context->get_Child_Node( Name = wd_This->wdctx_Zz_00_Test_Form_000 ).
get element via lead selection
Elem_Zz_00_Test_Form_000 = Node_Zz_00_Test_Form_000->get_Element( ).
get single attribute
Elem_Zz_00_Test_Form_000->set_Attribute(
exporting
Name = `TEST1`

Hi Volker,
Thanks a lot for your help.:)
When I compile the WDA, the WDA don't occur any error. The WDA occurs error when I run the WDA.
1. In the st22 transcation code, I found the following code:

To explain in simple terms, i've done the following:
1. Stored the context table data in a XML format in a string variable
2. Converted the string variable to xstring format using fm 'SCMS_STRING_TO_XSTRING'
3. Job Open
4. Identify the Actual FM Name
5. Genarate Form
6. Job Close
7. Bind data (fpformoutput-pdf) to the PDF Source variable in context
Issue is, when i run application and download, i am only able to get a PDf with no data in it.
Interestingly, in debug mode, i am able to see some data.
Points to add: When i display in a PDF UIElement the output comes in two pages, and in debug mode when i see the variable FPFORMOUTPUT-PAGES, it has a value of 1.
May be am following the wrong approach or missing someting in code.
Any inputs, appreciated.
Thanks,

How to get changed data in ALV in Web Dynpro for ABAP

this code is ..get all data(changed and not changed)
but i want get changed data only, not all data.
how to get changed data?
Edited by: Ki-Joon Seo on Dec 27, 2007 6:04 AM

Hi,
To get only the changed data in the ALV grid of a WD, you need to capture the "ON_DATA_CHECK" of the ALV grid.
To this please do the following in the ALV initialization of the ALV table settings :
    lr_table_settings->set_data_check(
            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CELL_EVENT ).
You may also do this:
    lr_table_settings->set_data_check(            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CHECK_EVENT)
The above two ways would depend on when do you need to check for the changed data. If you want to check the data as soon as it is entered, then use the first method. Else, use the second method.
You need to register an EVENT HANDLER for this event.(You may do this in your VIEW or Component Controller).
In this Event handler, you would find an importing parameter R_PARAM which is a ref type of      IF_SALV_WD_TABLE_DATA_CHECK.
The attribute T_MODIFIED_CELLS of this interface IF_SALV_WD_TABLE_DATA_CHECK will contain the modified cells of the ALV with the old & new values.

Error message in a table (not ALV)

Hi there,
i know that in ALV an error-message appears and the cell is marked if an user puts a not allowed value in the cell.
Now i want to achieve the same in my non-alv-table. If a user enters a value in a specific cell, i want to output a message and mark the specific cell as "wrong". Can anyone provide me with a code-example?
Best regards
David

HI,
Even in table cell if a value is entered that is not permitted ,system issues an error message and highlights the cell after some action is performed.
Case1: Suppose you enter a character value in date field and perform some action system performs the checks, issues an error message an higlights the cell.
Case 2: If validation of the entered value needs to be done programatically after an action is performed the use the below logici in the WDOBEFOREACTION method.
a) Get the node binded to the table( lo_node = wd_context->get_child_node('Node Name").
b) Using the node reference get alll the elements using the method GET_ELEMENTS of IF_WD_CONTEXT_NODE i.e lo_node.
c) Now loop at list of elements and for each element use the method GET_STATIC_ATTRIBUTES to get the attribute values
d) Do the required validation if some error is found use REPORT_ATTRIBUTE_ERROR_MESSAGE using the attribute name and element refernece.
Hope this helps.
Regards,
Madhu.

WDA error in changing read only property of fields at runtime

Hello Friends,
I am creating a custom Web Dynpro ABAP Application for FI module in ECC 6.0
I need to make a set of fields uneditable/grayed out based on a value in a dropdown list. If the user chooses the other value (out of the 2 values provided) in the dropdown list, the set of fields need to made editable.
I created a context attribute of type WDY_BOOLEAN and bound this attribute to the "readOnly" property of the aforementioned fields. When defining context binding, I chose the option "Bind Directly to the Selected Attribute".
I have written the following code in the OnSelect event handler method for the dropdown:
I read the value in the dropdown which is stored in the variable "lv_payment_instrument". Based on this value, I am changing the value of the context attribute:
if lv_payment_instrument = 'X'.
DATA lo_nd_check_fields1 TYPE REF TO if_wd_context_node.
DATA lo_el_check_fields1 TYPE REF TO if_wd_context_element.
DATA ls_check_fields1 TYPE wd_this->Element_check_fields.
DATA lv_editable1 TYPE wd_this->Element_check_fields-editable.
navigate from <CONTEXT> to <CHECK_FIELDS> via lead selection
lo_nd_check_fields1 = wd_context->get_child_node( name = wd_this->wdctx_check_fields ).
@TODO handle non existant child
IF lo_nd_check_fields IS INITIAL.
ENDIF.
get element via lead selection
lo_el_check_fields1 = lo_nd_check_fields1->get_element( ).
@TODO handle not set lead selection
IF lo_el_check_fields1 IS INITIAL.
ENDIF.
@TODO fill attribute
lv_editable = 1.
set single attribute
lo_el_check_fields1->set_attribute(
    name = `EDITABLE`
    value = 'ABAP_FALSE' ).
elseif lv_payment_instrument = 'Q'.
DATA lo_nd_check_fields TYPE REF TO if_wd_context_node.
    DATA lo_el_check_fields TYPE REF TO if_wd_context_element.
    DATA ls_check_fields TYPE wd_this->Element_check_fields.
    DATA lv_editable TYPE wd_this->Element_check_fields-editable.
*navigate from <CONTEXT> to <CHECK_FIELDS> via lead selection
    lo_nd_check_fields = wd_context->get_child_node( name = wd_this->wdctx_check_fields ).
*@TODO handle non existant child
   IF lo_nd_check_fields IS INITIAL.
   ENDIF.
*get element via lead selection
    lo_el_check_fields = lo_nd_check_fields->get_element( ).
*@TODO handle not set lead selection
    IF lo_el_check_fields IS INITIAL.
    ENDIF.
*@TODO fill attribute
   lv_editable = 1.
*set single attribute
    lo_el_check_fields->set_attribute(
      name = `EDITABLE`
      value = 'ABAP_TRUE' ).
endif.
When the user chooses either of the 2 values in the dropdown, the set of fields are made uneditable. I am unable to make them editable again.
I would greatly appreciate your inputs/thoughts on how to rectify this error.
Regards,
Arun.

Hi,
Create one attribute of type WDY_BOOLEAN , i think u already done.
First get selected dropdown value into one variable.
For example :
lo_el_segment1 = WDEVENT->GET_CONTEXT_ELEMENT( 'CONTEXT_ELEMENT' ).
get all declared attributes
lo_el_segment1->get_static_attributes(
IMPORTING
static_attributes = ls_segment1 ).
now ls_segment1 has selected drop down value.
DATA : lv_dropdown type string .
lv_dropdown = ls_segment1-segment.
If lv_dropdown = 'X'.
set single attribute
lo_el_check_fields1->set_attribute(
name = `EDITABLE`
value = ABAP_FALSE ). // No Quotes, ABAP_TRUE or false not works use 1 0r 2 or ' ' 'X' .
elseif lv_dropdown = 'Q'.
set single attribute
lo_el_check_fields1->set_attribute(
name = `EDITABLE`
value = ABAP_FALSE ).
else.
set single attribute
lo_el_check_fields1->set_attribute(
name = `EDITABLE`
value = ABAP_TRUE ).
Hope it solves..
cheers,
Kris.

Also check this excerpt from Thomas Jung for previous Thread on same issue
SE78 is the old graphics store for SAPScript. Not the best place to store images now because of the limited support for graphic types. Usually you store as Bitmaps there, making those images highly inefficient for usage on the web. Unless you have thousands of images you need to use, I would suggest downloading them, converting their format and storing them in the MIME repository. If you absolutely must access those images for some reason, look at the function modules in group STXBITMAPS - function module SAPSCRIPT_GET_GRAPHIC_BDS or SAPSCRIPT_BITMAP_GET depending upon which of the two formats/folders where used in SE78.
