Set context attribute property

Hello.
I have bound the visibility of a ui element to the property of a context attribute.
What's the syntax the set the property of the context attribute to invisible ?
Thanks and regards.

Hi Carola.
Another way:
METHOD set_shiptos_visible .
DATA:
    node_ctr_struct                     TYPE REF TO if_wd_context_node,
    elem_ctr_struct                     TYPE REF TO if_wd_context_element,
    stru_ctr_struct                     TYPE wd_this->element_ctr_struct ,
    item_pn_visible                     LIKE stru_ctr_struct-pn_visible.
node_ctr_struct = wd_context->get_child_node( name = wd_this->wdctx_ctr_struct ).
elem_ctr_struct = node_ctr_struct->get_element( ).
IF visible EQ abap_true.
    elem_ctr_struct->set_attribute(
      EXPORTING
        name = `PN_VISIBLE`
        value = '02' ).
ELSE.
    elem_ctr_struct->set_attribute(
      EXPORTING
        name = `PN_VISIBLE`
        value = '01' ).
ENDIF.
ENDMETHOD.

What is "Primary attribute" in Context attribute property?

Dear Friends...
Many properties..in Context attribute properties..
Attribute name, Type, Read-only, Primary attribute..and so on..
What is primary attribute and how to check it?
I don't check it. and i don't know what is this..?
Please answer..
Thank you.

Hi,
The primary attribute specifies the lead column for the configuration editor. The maximum of one attribute for each node can be declared as a primary attribute.
Dependencies:
The primary attribute is only allowed in the context of configuration controllers.

Invert Attribute/Property ("NOT") for context binding

When I bind a contex node to the property "enabled" of a checkbox, there is a special setting for the binding called "Invert Attribute/Property ("NOT")", which I can use to invert the value from the context.
However, for the property "checked" of the checkbox, this setting is not offered.
Is there anything, i can do?

Hi Daniel ,
Invert property is not available for checked because its the data which it is going to be represented by checkbox like for inputfield - value , textview- text . properties are enabled , readonly......for which this function id present.

Not able to get the context attribute set in ServletContextListener

Hi all,
I have written a simple ServletContextListener and set an attribute in it. when i am trying to retrieve the attribute value in my servlet, I am getting as null. Could anybody please let me know about this if i need to add any more changes.
Below is the complete code of my sample application

PrintWriter out = response.getWriter();
out.print("The required value is... "+output);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
OUTPUT
When accessed with any url as below:
http://localhost:8080/helloworld/u
gettting output as "The required value is... null" . Because i set the context attribute, I am expecting not null. Can anybody suggest me on this.

context.setAttribute("myTest", "mkmmkmmkm");
String output = (String) getServletContext().getAttribute("testMe");You set "myTest" but try to get "testMe"

How to set multiple values in one context-attribute

Hi all,
Anybody knows a possibility to set multiple Values to a context-attribute?
I know it how to get it with the following code:
String break[]= request.getParameterValues("break");
Now I want to do something like:
request.setParameterValues(break[no]);
where no is a counter in a loop.
With the Method setAttribute(), I overwrite the previous inserted value.
Thanx
Robert

I have not explizit declared break as an array.
It is the Context- Attribute I want to send. I thaught that I can use it as an array in the same way I can do it when I send Data from an HTML- Form (with multiple values) to an servlet.
I don't know how to declare the Attribute explizit as an array.
that it is you wanted to know?
I think my main problem is to get an array from the servlet to the jsp. Is there an other possibility (other than via Context-Attributes) to do that?
thanx
robert

WCF :Consider marking the type with the CollectionDataContractAttribute attribute or the SerializableAttribute attribute or adding a setter to the property

Currently I am working in a WCF project here when I try to send data from WCF Project 1 to WCF project 2 I am getting the below error.
The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:subscriber. The InnerException message was 'The use of type 'Integra.Business.ICC.ObjectChangeTracker'

Setting Application Context Attributes for Enterprise Users Based on Roles

Hello,
We have an Oracle 11g database with a table containing data from multiple sites (a SiteID field identifies the site for a record). Since application users can have access to different subsets of sites, we would like to use Oracle's Virtual Private Database feature to enforce row-level security on the table.
I did a successful proof-of-concept with database users. I created a role for each site (example: USER_SITE_A, USER_SITE_B, ...), and then assigned the appropriate site roles to each database user. I then created a package (run via a logon trigger) which set application context attributes for each site. If the current database user has been assigned a role for a given site, then the corresponding attribute named "SITE_PRIVILEGE_SiteID" is set to 'Y'... otherwise, it is set to 'N'. Here is the code which worked to set application context attributes for database users:
-- For each record in my RoleSitePrivileges table, set
--   an attribute named 'SITE_PRIVILEGE_<SiteID>'.
--   If the current user has been assigned a role matching
--   the value in the 'RoleName' field, set the corresponding
--   attribute to 'Y'... otherwise, set it to 'N'.
FOR iPrivRec IN (SELECT RoleName, SiteID
                   FROM RoleSitePrivileges
                   ORDER BY SiteID)
   LOOP
      SELECT COUNT(*)
        INTO roleExists
        FROM dba_role_privs
        WHERE granted_role = UPPER(iPrivRec.RoleName)
          AND grantee = USER;
      IF roleExists > 0 THEN
         DBMS_SESSION.set_context(
                     namespace   => 'my_ctx',
                     attribute   => 'SITE_PRIVILEGE_' || iPrivRec.SiteID,
                     value       => 'Y');
      ELSE
         DBMS_SESSION.set_context(
                     namespace   => 'my_ctx',
                     attribute   => 'SITE_PRIVILEGE_' || iPrivRec.SiteID,
                     value       => 'N');
      END IF;
   END LOOP;To finish things off, I created a security policy function for the table which returns the following:
RETURN 'SiteID IN (SELECT TO_NUMBER(SUBSTR(attribute, 15))
                     FROM session_context
                     WHERE attribute LIKE ''SITE_PRIVILEGE_%''
                        AND value = ''Y'')';This setup worked great for database users. I am now working to do a comparable proof-of-concept for enterprise users created in Oracle Internet Directory (OiD). I have Enterprise User Security (EUS) up and running with OiD, global roles created in the database, enterprise roles defined in EUS with global role assignments, and enterprise roles assigned to OiD users. The enterprise users are able to successfully login to the database, and I can see the appropriate global role assignments when I query the session_roles view.
I tried using the same application context package, logon trigger, and security policy function with the enterprise users that I had used with the database users. Unfortunately, I found that the application context attributes are not being set correctly. As you can see from the code above, the applicaiton context package was referencing the dba_role_privs view. Apparently, although this view is populated for database users, it is not populated for enterprise users.
I tried changing the application context package to use invoker's rights and to query the session_roles view instead of the dba_role_privs view. Although this package sets the attributes correctly when called manually, it does not work when called from the logon trigger. That was an oops on my part, as I didn't realize initially that a PL/SQL procedure cannot be called with invoker's rights from a trigger.
So, I am now wondering, is there another view that I could use in code called from a logon trigger to access the roles assigned to the enterprise user ? If not, is there a better way for me to approach this problem? From a maintenance standpoint, I like the idea of controlling site access from the LDAP directory service via role assignments. But, I am open to other ideas as well.
Thank you!

WD ABAP. set context noe for an inputField

Hello community,
Does anybody know how to set a context attribute that mapped to an inputField?
node = wd_context->get_child_node( 'NodeName' ).
node->bind_elements( new_items = ANY_TABLE ).
It seems to be very inconvenient to pass any table (ANY_TABLE). Why can't I just pass a string to this method?
Thanks.

Hi,
Do you have general understanding about context structure and data binding?
You are binding attribute to the particular property, not a node (with some exceptions like dataSource for table). But to set attribute you need at least one node element. There is always one - root. You can define cardinality of node 1..x and in this case you don`t need to create or bind your node. You can immediately set attribute value.
Best regards, Maksim Rashchynski.

Need Clarification for the Attribute Property (Calculated)

hi
I am new to Web Dynpro and i am in need of clarification regarding the Attribute
Property - Calculated
Thanks in Advance
Regards
S.Chandran

Hi,
Calculated Property in webdynpro is required when you want to handle node context attribute programmatically.
When you say Context Attribute as True, it generates two methods, Setter and Getter Method for that attribute.
In getter method you will be getting one element it is the context node, where you created attribute. These methods will be called automatically.
For more Info check this link

Hope that helps

Using Static Variable against Context Attribute for Holding IWDView

Dear Friends,
I have a method which is in another DC which has a parameter of the type IWDView. In my view, I will have an action which will call the method in another component by passing the value for the view parameter. Here, I can achieve this in 2 types. One is - I declare a static variable and assign the wdDoModifyView's view as parameter value and I can pass this variable as parameter whenever calling that method or the second way - create an attribute and assign the same wdDoModifyView's view parameter as its value. Whenever I call this method, I can pass this attribute as parameter. What is the difference between these two types of holding the value since I am storing the same value i.e., wdDoModifyView's view parameter. But when I trigger the action from different user sessions, the first type of code (using static variable) prints the same value in both the sessions for view.hashCode() and View.toString(), but the same is printing the different values when I pass the attribute which holds the view parameter.
Clarification on this is highly appreciated
The problem I face is when I use static variable to get the view instance and export the data using the UI element's id, the data belonging to different user sessions is mixed up where as when I use Context Attribute, the same problem doesn't arise. I want to know the reason why it is so. Is there any other place or way where I can get the current view instance of each session instead of wdDoModifyView?

Hi Sujai ,
As you have specified the problem that we face when we use static attributes, when end users are using the application .
Static means i have n number of objects but the static variable value will remain same every where.
when it is context attribute for every object i.e nth object you have a nth context attribute i mean nth copy of the context attribute.
so every user has a unique Iview parameter , when context is used and
when static is used , assume you have userA , his iview is set this intially and u have another user B , when he is using , since the variable is static and when you access this variable you will get the value of userA.

Can't set managed bean property:

Hi,
I am trying to experiment with JSF and I am extending an example I downloaded from the web. When I added a new secret field and extened the bean. I get the following error. I trying to resolve this problem from two days , cant figure out why I get this exception. I tried changed the property name I still get the same error. It is something to do with the bean, I am not sure why its not able to set the property, I know that the get and set methods exist in the class file. Any help would be greatly appreciated . I have pasted the bean file, faces-config.xml, and the inputname.jsp file below. Thanks a lot.

Using dynamic context attributes with flashisland

I recently started looking at flashislands.
Going through the SDN tutorials on this topic, I noticed that the declarations of GACDATASOURCE and GACPROPERTY properties inside web dynpro and their counterpart variables inside flex are a bit static (all naming and binding is done at design time).
So I'm asking if there's a way inside flex to dynamically capture the values of the attributes of a web dynpro context node that is bound to an ArrayCollection variable inside flex without knowing the names and the amount of the attributes of the context node?
Here's my situation:
I have a context node (REPORT_DATA) inside web dynpro that at design time has no attributes.
The attributes and their names are created dynamically at runtime.
It is even so, that over time the amount of attributes may vary.
Inside the web dynpro, the contents of this context node (REPORT_DATA) are shown in a (dynamically built) table.
Besides using the table, I'm trying to show the same contents as a piechart and as a columnchart in a flashisland.
The ROOTUIELEMENTCONTAINER of the FlashIsland view in web dynpro only contains a GACDATASOURCE element at design time.
The 'dataSource' property of this GACDATASOURCE is bound to the context node REPORT_DATA.
The 'name' property of this GACDATASOURCE is bound to an ArrayCollection variable inside flex (named dataSource).
So much for the static part created at design time.
At runtime inside web dynpro the correct GACPROPERTY's are created, based on the - over time changing - amount and the names of the context node.
Suppose my REPORT_DATA context node at runtime starts with 3 attributes: ATTR1, ATTR2 and ATTR3
Also suppose the node contains 2 elements: [ {"1_1", "1_2", "1_3"} , {"2_1", "2_2", "2_3"} ]
The dataSource variable inside flex also contains 2 entries with 3 elements each.
The code to show the value of (for example) the first element of all entries inside the ArrayCollection variable would be:
+for each( var o:Object in dataSource) {
var s:String = o.ATTR1;
Alert.show( "the 1st value = " + s ); // 1_1 for the first entry, 1_2 for the second
}+
I can then use the myAC variable inside flex as dataprovider for various other objects.
This works fine.
But inside flex I can only capture the value of an attribute when I know its name at design time (like ATTR1 in the sample code above).
And that's not what I want.
Inside flex I want to capture the value of the context attributes dynamically in a (correctly typed) flex variable without knowing the names and the amount of the context attributes.
Is this possible?
Thanks in advance for - any - response.
Bart.

Hi again,
I tried the same thing by creating a dummy context node without any attributes, and adding all attributes at runtime using the add_attribute method. In that case too, it doesnt work. All the attributes are available in the dynamic attributes of the node element, but are not getting displayed.
Any help would be greatly appreciated. Thank you.

How to set a attribute value of a sub node binded to a table.. pls respond.

Hi friends,
I have context defined like this.
     Head_node ( table 1)
          Item_node ( table 2, sub node ). ( now this im saving in global internal table).
so now when i hit save button, im passing my internal table (it has col1- sales order no, col2 item details(table type, which can have more than one record) to a FM, to create sales order.
My sales order is getting saved.
But the function module will return some new values (like sales order number, item number etc).
Now i want these values to be updated in my context.
Meaning whenever after that i do get_attribute, i should get these new (sales order no, item no ) also.
I dont know how to set the context values of sub nodes , so im missing these values.
kindly respond back to me..
thanks in advance,
Niraja

Its very simple.
Follow these steps. e.g you want to get the new sales order number. Define a attribute in ur node (or set of attributes in ur case as per reqruirement) say new_so_number.
Check your FM, if its returning new_so_number then it's fine, otherwise you have to change the FM to return the new_so_number or you have to get from db table somehow, which best suites your req.
So once you have new_so_number after calling the FM, say in lv_new_so_number field. Then write this code to set the attribute (change the variables as per your context attributes)
DATA lo_nd_head TYPE REF TO if_wd_context_node.
DATA lo_el_head TYPE REF TO if_wd_context_element.
DATA ls_head TYPE wd_this->element_head.
DATA lv_new_so_number LIKE ls_head-new_so_number.
* navigate from <CONTEXT> to <HEAD> via lead selection
lo_nd_head = wd_context->get_child_node( name = wd_this->wdctx_head ).
* get element via lead selection
lo_el_head = lo_nd_head->get_element( ).
lv_new_so_number = new_so_number. " (You got this as a exporting parameter of FM etc..)
* get single attribute
lo_el_head->set_attribute(
    EXPORTING
      name = `NEW_SO_NUMBER`
      value = lv_new_so_number ).
Hope it works.

Validation of context attributes with adaptive webservice model

Hi, I am creating a Web Dynpro Java application (on top of Netweaver AS 7.0) using an adaptive webservice model to invoke a webservice.
The webservice has some request attributes of type string with limited length (for example limited to 1 character). I bound the model to component controller context and created a mapping between the component controller context and view context. In the view, I created a form which is bound to the context attributes.
When user enters string values, which are longer than the maximum length specified in webservice WSDL, and submits the form, an exception is thrown when Web Dynpro runtime is trying to assign entered values into context attributes:
com.sap.dictionary.runtime.DdCheckException: Length of character string "abcdef" must be smaller than or same as MaxLength 1;
    at com.sap.dictionary.runtime.DdTypeString.checkValid(DdTypeString.java:195)
    at com.sap.tc.webdynpro.model.webservice.base.model.BaseGenericModelClass.setAttributeValue(BaseGenericModelClass.java:304)
    at com.sap.tc.webdynpro.model.webservice.gci.WSTypedModelClass.setAttributeValue(WSTypedModelClass.java:62)
    at at.gov.bmf.demo.comp.employee.model.OrganizationalAssignment.setEmployeeGroup(OrganizationalAssignment.java:52)
    at at.gov.bmf.demo.comp.employee.wdp.IPublicEmployeeDemo$IOrganizationalAssignmentElement.wdSetObject(IPublicEmployeeDemo.java:1552)
    ... 32 more
This exception is thrown before my non-validating action is executed, so I am not able to prevent it or handle it.
Is there any way how to catch this exception or prevent it?
Does anyone know where these model restrictions are stored? I searched the XML files generated for the model, but I haven't found anything. Does the Web Dynpro runtime access WSDL everytime it needs to validate request parameters?
Thanks,
Tomas

No ,This is the preferred and safer way to separate the Model Node and and Input Node and relationship between them by using mapping.
You create your context structure for input and then on action set user input to model data.
Safer it means : Sometimes it happen that model data not populated properly due to network or wrong user input etc ,this time our presentation will be safe and display the proper error message rather the screen went away with null pointer exception.
Regarding your - it require a lot of work. It too much convince for us that rather than writing 50 lines of code
for only input length validation WebDynpro provides us a better model driven solution.
