i do to point the cursor on CANVAS53?
With Regards
Vids
Vidu,
you can also do like this.
in form property set navigatation to BLOCK and use the below code. in WNFI
BEGIN
SHOW_VIEW('CANVAS53');
HIDE_VIEW('CANVAS2');
END;ON KEY-F5 TRIGGER
BEGIN
NULL;
END;Regards

How to handle multi valued attributes
Hi All,
I am supposed to populate multivalued attributes for a field in oim resource profile. Lets assume the field is mailbox. The issue is that I am supposed to reconcile this field from the directory server during initial load. The mailboxes are fetched from the DS based on organization. For provisioning I have to get the mailboxes from the database and these mailboxes are based on the role a user has. At the time of provisioing, I am supposed to populate the mailbox field with values the user already has been provisioned with and also display the mailboxes that he can get access to. I have created the mailbox as a resource with id and name as two of its fields. Could someone please tell me how do I handle this?
Thanks,
SupreethaI am not sure if I could follow the same thing as mentioned in the link above. Here is my case, Role is a multi valued attribute which i need to handle in oim and is very different from the usual roles. For this purpose, I have created roles as a resource object with role_id as field in its process form.When an admin logs in to assign a new role_id, he should be able to see only those roles for assignment that the admin's org has. I have these org and role mappings in a custom table that I have created in the oim schema. How will I able to display only these available role_ids so that the admin can choose them and assign for the role resource.
Could you please let me know how do I do the config in oim?
Thanks,
supreetha

How to handle multi row update in table?!
Hello,
I am searching for a solution to edit/update a lot of rows of a table at one time. The user has the ability to edit all cells of this table and then update this by pressing a submit button.
I have a managed bean with an collection of objects. Each object represents on row.
How is this handled in JSF? Is it only necessary to bind the datatable to the collection?
Thanks,
ThomasIs it only necessary to
bind the datatable to the collection?Yes.
Don't forget to put the collection in session scope. -
How to Handle Multi Value Indexes
Hi all,
i'm a newbye and i've a class attribute which is a String Array, and i want to create a secondary index on this attibute.
I'm wondering which is the best solution to achieve this.For new users we recommend the DPL. It was created for ease of use.
However, the DPL doesn't support arrays as key fields. So you would have to concatenate the strings with a delimiter and use a single String field, or if the number of strings is fixed use a composite key with a separate String field for each element. Some references are:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/SecondaryKey.html
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/KeyField.html
If you use the Base API or the Collections API you can use a tuple binding to create a secondary key DatabaseEntry from a String array. For example, you can call TupleOutput.writeString for each element.
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/bind/tuple/TupleBinding.html
What sort order for your key are you expecting? I assume you want the keys sorted by each string in array element order. That means you should NOT write the length of the array at the beginning of the key, since that will cause the sort order to be primarily based on the array length. Instead you can write an empty string as a terminator, or use TupleInput.available to test for whether you've read all strings in the key. The latter is recommended.
I assumed above that the array length is variable. If it is fixed length, you don't need a terminator.
If you don't care about key sort order, consider using a hash of the String array as the key. The hash field could be a single key field, which would work with the DPL.
I'm giving you a lot of general info. If you can be more specific about what you're doing, I can give more specific advice. I suggest that you start with one of the APIs and try doing what you want. Then you can post specifics about the questions you run into.

Handling multi byte languages in Web Service
Hi,
I am calling a web service and its working fine with English language i.e web service is returning correct parameters with English.
But it's returning me Junk characters when i call web service with multi byte languages like Japanese, Russian etc.,
Generally while configuring Web Service or calling a web service using proxy - it asks for a user id/ Pwd but not a logon language (unlike while you login SAP it asks for Logon Language) so i am thinking since there is no option to enter log on language, its taking a default language i.e English so when i am passing japanese its returning me Junk Values.
Can any one please help me with this? How to handle multi byte webservice call? I am using ECC 5.0.
Thanks & Regards,
Pavan.I appreciate your thought but our webservice must be able to handle multiple languages not only Japanese. Users might call webservice in any language they prefer. If i change it my default to Japanese, i will have problem when users call webservice in Russian.

How does IDP handle multi-value attributes in directory?
I have a directory referenced by the IDP where the mail attribute is multi-value. Assertions being received by the SP are indicating that the mail attribute is null or empty. How does the Oracle IDP handle multi-value attributes from a directory? Is there a way to select the first entry in an array of multi-values?
On the IdP side, passing of multi-valued attributes is supported. Read this section:
http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/configuring.htm#BCGCGFCJ
Snippet (under 'Delimited Data'):
"In addition to supporting and passing multi-valued attributes, Oracle Identity Federation can also support delimited data to provide multiple values for assertion attributes ......"
This information is also available on the OIF screen for 'Add Assertion Profile'.
On the SP side, mapping a multi-valued assertion attribute to a local user attribute is NOT supported. Read this section:
http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/configuring.htm#BCGGEAEA
Snippet (under Submit/Reset button):
"Note: Mapping an assertion attribute containing multiple values to a local user is not supported."
So, basically, there is no way to send only the first value of an LDAP attribute.

Newbie: How to handle a multi-step dialogue with no session?
I can't see how to handle the following trivial problem:
1. The user clicks on a button to retrieve values from the database
2. The values returned are displayed in a table on the same page
3. The user clicks a button next to the desired element
4. Some action is performed
I can achieve steps 1, 2, 3 but fail on step 4: the action is not called.
One prerequisite is that I don't want to store anything in the session or application scope.
In the example that follows, when you click on "Show Element" the action is not performed.
This is myExample.jsp:

I didn't realise I could use inputHidden for anything more complex than a single string...
I have added a h:inputHidden for the elements array but it still doesn't work.
How should it be used?
<h:form>
<h:inputHidden value="#{myExample.elements}"/>
<h:commandButton action="#{myExample.doSearch}" value="Search Database" />
...While debugging I noticed that at the last button-press the getElements method is called twice before setElements, returning null. -
How to handle multiple records in BPMN process
Hi All,
We are using Oracle BPM 11g.In my requirement,I am using the database adapter to get the data from table and I need to validate the each record and update the status of that record from the BPM Process.But I dont know how to handle if multiple records come at a time.Can anybody please helpout from this problem.
Thanks in advanced.
Narasimha Rao.Can you have a look at this post: http://redstack.wordpress.com/2010/09/30/iteratingtraversing-arrays-in-bpm/
It's solving a different problem, but the key is that it's using a multi-instance subprocess to iterate over an array of "things" that need to be acted in. In your case it's the set of results from the db query rather than the set of tests in the example. But the principle is the same. You'd take collection of rows from the DB and process them in a multi-instance subprocess. The text that begins with the following would be good place to start:
"Now let’s implement the body of our process. We will use the Subprocess object to handle the traversal of the array of tests. Drag a Subprocess from the component palette on the right into the process and drop it on the line between the Start and End nodes."
In the loop characteristics you'd define whether you want to execute serially or in parallel. -
How to handle selection event in alv component
Hi all,
i am new to webdynpro abap. and i want to know how to handle selection event(such as select all / unselect ) in my simple alv application.
Thanks very muchHi,
By default when you use the selection mode for the ALV as Multi/Mutli No Lead then this option is enabled.
Try to implement the event ONLEADSELECT and check wether this event is triggered or not.
DATA: lo_value type ref to cl_salv_wd_config_table.
CALL METHOD lo_value->if_salv_wd_table_settings~set_selection_mode
EXPORTING
value = cl_wd_table=>e_selection_mode-multi_no_lead.
Try to implement these event for ALV and put a break-point and test which event is getting triggered.
ON_CLICK
ON_DATA_CHECK
ON_FUNCTION
ON_LEAD_SELECT
ON_STD_FUNCTION_AFTE
ON_STD_FUNCTION_BEFO
Please provide more inputs.

How to handle the trigger sequence
I really do not have any idea for this question.

i defined two trigger for AFTER, trigger run orders are acorrding to. before statement level, before row-level, after row level and after statement level.
so my trigger actually can not implement requirement. how to handle it. now i try to use this rule: select w.essn, w.pno,p.pnumber, p.dnum from works_on w, project p where w.pno=p.pnumber; in statement level trigger. howerver in row-level trigger i can not get value i need(p.dnum i can not get its count). if you guy have any other ideas, pls give me some advise. my brain is really run out of.
Thanks for your help!!!I would recommend creating a package/procedure that is the only way to insert a user into the works_on table. Then inside this procedure you need to serialize access to the works_on table by using a select for update. Then you can count the number of projects and ensure that the new works on is valid.
If you try to use triggers then due to Oracle's mutli-versioning, if two users insert the same data at the same time, the data integrity will be violated.
You will obviously have an employee table. I have created one here as follows:
create table employee (essn varchar2(9) primary key);
insert into employee values ('999999999');
Then you can use this table to serialize access to the works_on table by issuing a select for update against it. If you don't do this then two users executing the procedure at the same time will violate the constraint. It is important that you understand this and try it out with multiple sessions so that you understand it.
create or replace procedure insert_works_on
(p_essn varchar2, p_pno number, p_hours number)
as
l_essn varchar2(9);
l_count number;
begin
select essn
into l_essn
from employee
where essn = p_essn
for update;
select count(*)
into l_count
from works_on w
join project p on p.pnumber = w.pno
where w.essn = p_essn
and p.dnum = (select dnum
from project
where pnumber = p_pno);
if l_count < 2
then
insert into works_on values (p_essn, p_pno, p_hours);
else
dbms_output.put_line('Employee works on more than 1 project for dept');
end if;
end;
Then you can try it out:
begin
insert_works_on('999999999',1, 10);
end;
commit;
begin
insert_works_on('999999999',2, 20);
end;
commit;
begin
insert_works_on('999999999',3, 30);
end;
commit;
The first two will succeed and the last will fail. Try it out in multiple session as well to ensure it works for a multi-user scenario. -

Its occurs because you're trying to access a objects with null reference. Or you forgot to create an instance or an error occurs during the instance creation. So You should put all your "Procedures and business logic" inside a Try/catch block. as follow.

ENDTRY.
The TRY block defines a guarded area whose class-based exceptions can be caught in the subsequent CATCH blocks. If no exception occurs in the TRY block and it reaches its end, the system continues the processing after ENDTRY. If a class-based exception occurs in the TRY block, the system searches for an exception handler in the same or an external TRY control structure.

How to handle null values in RTF templates
Hi - I have two groups in a report for different SQL and two formulas for each group, CF_ELE_CNT and CF_ELE_CNT1. In the template I use the below code to print or not print a section.
<?if:number(CF_ELE_CNT +CF_ELE_CNT1) >0?>
The problem is when there is no data in the second group its not creating the XML tag for CF_ELE_CNT1, though CF_ELE_CNT has 13, it still does not print that partucular section. If I remove CF_ELE_CNT1 from the condition it works fine. I was wondering how to handle this.
Any help would be appreciated!!
Thanks,
RavHey Rav,
You can add a check to identify it the element/tag is present or not
<?if:(CF_ELE_CNT1)?> will give true, if the element is present otherwise falsesince you are adding the two elements, you have to add a or condition.
<?if:(CF_ELE_CNT and number(CF_ELE_CNT) >0 ) or ( CF_ELE_CNT1 and CF_ELE_CNT1 >0)?> -
