Error when trying to create a Dynamic UI Element(DropDownByKey)

Dear All,
I am trying to create a Dynamic UI element(dropdownbykey) .
I used the following code which i wrote in domodify:
if (firstTime)
IWDTransparentContainer thetransparent =(IWDTransparentContainer)view.getElement("AttributeDynamic_TransparentContainer");
IWDNodeInfo node = wdContext.getNodeInfo().addChild(
"DynamicNode",null,true,true,false,true,false,true,null,null,null);
                          IWDAttributeInfo attr1=node.addAttribute("attrib00","ddic:com.sap.dictionary.string");
IWDAbstractDropDownByKey Sizedropdown=(IWDAbstractDropDownByKey)view.createElement(IWDAbstractDropDownByKey.class,null);
Sizedropdown.bindSelectedKey(attr1);
thetransparent.addChild(Sizedropdown);
When i deployed it i got the following error:

Dynamic layout elements determination logic for output of Pro-Forma Invoice

This is my requirement below. Please give the suggestion
Business requires output to be generated in name of the client, with client logo and scenario specific data elements. To do this in Standard SAP will require to define hundreds and hundreds of layouts. By making most of the client/scenario elements on the layout we can greatly reduce the number of required layouts and reduce implementatuion effort and lead-time.
     The goal is to define a generic table that will hold most of the dynamic layout elements for different document types and countries, including logo, sender address etc.
      For this we will create Z-versions of the output types BA00 ( Order Confirmation, ZPRI (Pro-Forma Invoice) and RD00 (ZD00 Invoice).The layout text blocks will be permanently fixed.The print Program user-exit should call the Z-table that holds the dynamic layout elements and retrieve these elements and merge them with the matching layout text block.
Message was edited by: janardhan b

Hi Janardhan,
   Even I have faced the similar situation.but what we have done is instead of calling the dynamic text elements..Why don't we call the text elements based on the required condition ,Then u dont have to maintain all the text elements required in the table.In the table we can only have the doumnent type,client name,logo name and address.
In the print program if u r using script layout then call the required text elements (write_text) based on the client name and document type that is fetched from the Z-table,Otherwise if u r going for smartforms then with in the layout give the condition under the conditions node of the window or the text.

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).

How to create dynamic list element in Site Studio designer?

Hi all,

Creating Dynamic UI Elements in Web Dynpro ABAP

Hi,
I want to an application in which the context nodes and the UI Elements for the second screen get created dynamically at run time based on the input on the first screen
First i have used this method :
cl_wd_dynamic_tool=>create_nodeinfo_from_struct()
to create the dynamic context nodes.
I have checked in debugger and the dynamic context node is getting creates successfully.
I have saved the reference for the context node in DYN_NODE.
Now for creating the dynamic UI Elements corresponding to the attributes of this context node, i call the method :
cl_wd_dynamic_tool=>create_form_from_node(
ui_parent = group_1
node = dyn_node
inputlength = 20 ).
But this thing is dumping.
This is the dump.
The following error text was processed in the system CG7 : Adapter error in &VIEW_ELEMENT_TYPE& "BP_ICLIENT" of view "ZWD_ONLINE_FORMS.FINAL_VIEW": Context binding of property VALUE cannot be resolved: Node FINAL_VIEW.1.BP does not contain any elements
Where BP_ICLIENT is the first attribute of the dynmaic context node BP created..
Please Help.

Using a Site Studio 10R4 Dynamic List Element Definition

Hi All,
I've created and can use a Static List Element Definition > Region Definition > Region Template with no problems based off of the 10gR4 samples.
However, there is no example that I've found to utilise the Element Definition of a Dynamic List. I'm attempting to use the same sample code as provided for a Static List but having no luck displaying the results of the query...
Does anyone have some sample code used in a Region Template or Sub Template to show how we use a Dynamic List Element Definition please?
I noted from another thread in this forum that there are some iDoc calls to make which load the query defined in the Element Definition... I can't find any documentation regarding this either.
Thanks

Dynamic UI Element multiple times

Dear all.
I am able to create one dynamic UI element, and bind to a node.
Now the point is my node is of cardinaly 0..n.
Based on some logic, there can be various (or 0) text edit UI element dynamically.
How can I write this code? Any help is greatly appreciated.
Thanks in adv!

Hi,
Check this code
data: LR_CONTAINER type ref to CL_WD_UIELEMENT_CONTAINER,
LR_BUTTON type ref to CL_WD_BUTTON,
LR_FLOW_DATA type ref to CL_WD_FLOW_DATA.
do 10 TIMES.
LR_BUTTON = CL_WD_BUTTON=>NEW_BUTTON( ).
LR_FLOW_DATA = CL_WD_FLOW_DATA=>NEW_FLOW_DATA( element = LR_BUTTON ).
LR_CONTAINER ?= view->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).
LR_CONTAINER->ADD_CHILD( LR_BUTTON ).
enddo.
it is for inserting 10 buttons on the same basis you can insert number of text views......

Can't create dynamic html elements with jsp????? important

Hi All,
I am having problem creating dynamic html elements with jsp tags, i have tried to use EL and java scriplet, both of them don't work.
i am trying to create dynamic menu in my "rightMenu.jspf", based on, if user has logged in or not.
some like this!
<jsp:if test ="${validUser == null}">
some simple text menu here
</jsp:if>
but it is not working. it simply loading all and images with in statement, regardless of whether user has logged in or not. i think some how if statement is not working properly.
"validUser" is a session bean, which is not creating at this point, it will created when user will log in successfully. and also this session bean does not exist at the page, where i am trying to check that .
Is there any way to create dynamic values in jsp. It is really important, is there any body who help me in this matter. i would be really grateful.

hi jaspre,
thanks for replying me. you know what, is it not something wrong with web.xml file. i remember once, i deleted some from there, a property with "*.jsp". i can't remember what exactly was it though.
all if statements works on files ending with extension ".jsp" but don't work only on with extension ".jspf". there must be to do with this.

How to read values of dynamic UI elements in a backing bean?

Hi, I have an ADF page where some of the UI elements (in this case, checkboxes) are dynamically rendered as such:
<af:forEach var="row" items="#{backing_testPage.userList}">
<af:selectBooleanCheckbox id="checkbox" value="#{row.id}"
text="#{row.name}" selected="#{row.userSelected}"/>
</af:forEach>
I am wondering how can I read the values of these checkboxes in my page's backing bean. It does not seem possible to specify a distinct binding value for the selectBooleanCheckbox elements in order to tie them to a CoreSelectBooleanCheckbox variable in my backing bean (so that I could check whether the checkbox is selected or not).
When the page gets rendered, I did see that the checkboxes get assigned distinct ids like checkbox_1, checkbox_2, checkbox_3, etc... Not sure if that would help with this.
Would appreciate any tips on this as I've been struggling with this for awhile. Thanks!

You probably would do better with a SelectManyCheckbox. Here's how:
In your backing bean you need:
private String[] usernames;
public String[] getUsernames () {
return usernames;
public void setUsernames (String[] _usernames) {
usernames = _usernames;
}In your page:
<af:selectManyCheckbox value="#{backing_testPage.usernames}">
<f:selectItems value="#{backing_testPage.userList}"/>
</af:selectManyCheckbox>When the form is rendered any strings in the usernames array that are in the userList will be checked. When submitted, any checked items will be in the array.

Dynamic Structure / Element building

Hallo, I am new to Java and have some problems at building Elements and handling like passing them to some dynamic structure and letting the references be handled without losing the elements in memory.
There are also some questions about general memory usage. I hope it gets visual at this small testclass. Maybe you can pass me throuh to some reference post at topic?

          System.out.println(ob.size());
          long mem = Runtime.getRuntime().totalMemory(); //- Runtime.getRuntime().freeMemory();
          //@1 What about that here? total and free almost same value
          long time = System.nanoTime();
          System.out.println("Total Runtime Mem: "+Runtime.getRuntime().totalMemory()/Math.pow(2,20));
          System.out.println("Free Runtime Mem: "+Runtime.getRuntime().freeMemory()/Math.pow(2,20));

          System.out.println(ob.size());
          //@QUESTION I just want to know how to remove from vector. If i put it in the building loop
          //and remove it immediately after adding, memorysize does not grow. Here like you see the last

          //maybe I have to build the added element in another way? and not at adding but look @tested

          System.out.println(ob.size());
          //Here I ve tried clearing at once, but does not work either that way. The vector is empty and I ve lost Strings in memory
     //     ob.removeAllElements();
     //     ob.clear();
     //     ob = null;
     // System.gc();

}

Hmm, sorry... the format and some bytes were lost between copy and paste.Edit your post and use the tags to format the code.
And what does happen when I remove them while nobody holding references? If nobody has references to the objects, the garbage collector will collect them. Just putting them in an ArrayList won't lose them, the ArrayList will still have references to the objects.
tried also to build dynamic array myself but having problems with memory managmentNo, you have no problems with memory management.
cant get back to the amount of startup, even backwards does not work...That's because you're trying to do irrelevant things. Basically you're wasting your time.
Maybe I should trie interface building object?No, you should learn the basics of Java by going through the tutorials.
Have fun there.Thanks, you too!

How to bind the attribute in the context to a dynamic created element?

Hi, experts,
There are some attributes in the node context(ee_node) that contained the attribute named "ANSSA" in the view(test_view) in the WDA for abap. In the method modifyview of the view(there is a transfered parameter that represent the name of "ANSSA")
I want to create a dynamic element(inputfield) in the test_view. The element need bind the context attribute (ANSSA).Through the transfered parameter(para), I only know the name of the attribute binded.
How can I bind the attribute of the context in the following code?
METHOD modifyview .
*importing para type string.
*importing m_view type ref to if_wd_view.
data wd_inputfield type ref to cl_wd_input_field.
create one element automatically in the view.
wd_inputfield = CL_WD_INPUT_FIELD=>NEW_INPUT_FIELD(
                                    view = m_view
                                    id = para
                                    BIND_VALUE = ???
ENDMETHOD.
I don't know how to replace the "???" in the method modifyview? Do you give me some hint for it?
You can reply back to me via e-mail if you think we should discuss this internally at [email protected] or [email protected]
Thanks.

When I run the WDA, The web page occuring the error information:

But when I delete the code of the wddomodifyview, and create a inputfield in the layout of the view, and bind the "ANSSA" to the "value" property in the layout, the WDA is running correctly.
Do you give me some hints?
Thanks a million.

Context binding error in Dynamic UI element creation

Hi,
I am new to Webdynpro. I am trying to build an app for dynamic table data in an ALV,so creating an input field for table name dynamically.
I am facing a issue while binding the dynamic input field to the dynamically created context node attribute. The error description is: ERROR: Error in INPUT_FIELD "IF" of view "ZVK_DYNAMIC1.MAIN": Context binding of property VALUE cannot be resolved: The MAIN.1.INPUT node does not contain any elements (termination: RABAX_STATE).

Please help.

Hi Vishal,
Actually, for an input field the node should be with cardinality either 1...1 / 1...n. i.e. at least one element should exist. So you need to pass "is_mandatory = abap_true" while creating node.
Please modify your code as below
CALL METHOD lr_root_node_info->add_new_child_node
     EXPORTING
       name                         = 'INPUT'
       is_mandatory = abap_true
       is_multiple                  = abap_false
       is_multiple_selection        = abap_false
*      is_initialize_lead_selection = abap_false
     RECEIVING
       child_node_info              = lr_input_node_info.
Hope this helps you.

Dynamic text element (Text Symbols)

Hi,
How can we make text element dynamic?
Ex:
If I want a text "Consider date g_date" where g_date is populated from program. Can I pass g_text like <b>text-001 g_text</b>?
Thanks.

If you need it for a message, just use a predefined generic one, i.e
MESSAGE s000(0k) WITH 'Consider date' gdate '' ''.
Then you don't even have to define 'Consider date' as a text-symbol. But you can. Then it is
MESSAGE s000(0k) WITH text-001 gdate '' ''.

Clemens
