How to copy fields values between same class objects with filtering ?
Hi I'm facing a problem.
It started when thinking to the clone method for cloning objects.
And developed into a problem when trying to making something more complicate that just cloning.
Suppose you have two JPanels and one is a copy of the other suppose that u feed the copy to some methods for processing.
These methods modify simple data (ints,Strings, CustomClasses) and swing components too.
Now when I get the object back I want to copy all of the fields values to the original JPanel except for those who represent swing components or the like.
I want to do this automatically by writing some few rows of code.
How can I do this using reflection ?
How can I filter the Fields objects that I get from jpanelInstance.getClass().getDeclaredFields(); ? Which metod should I use then to check if is a subclass of java.awt.Component ?
I've read about many things on using reflection to invoke methods, constructors and so on.
But how do I get the fields values as I get the fields objects ?
Thanks for the attention, hope what is written is clear enough,
Estades.
Are you targeting a "worst design award"? What kind of "processing" would take place on a UI component?
I am sure from what you write that you missed to seperate your model from your view. Read about MVC and retry designing your application.

How to copy a value between items??
Hi friends,
[Apps R12]
I don't exactly know ho to do this:
Imagine you have a LOV.. and it retrieves a value in one of its attributes...
When selecting a value of that LOV.. I want one of those attribute values... be copied to other item in the same screen...
It would be te same as in Forms:
When-validate the lov ...
:block1.item2:=:block1.item1
where item1 is one of the columns retrieved by the LOV and item2 is another field on the screen....
Could any of you provide an example of how to do this?
Thanks!!!if (pageContext.isLovEvent())
// Form was submitted because the user selected
// a value from the LOV modal window,
// or because the user tabbed out of the LOV input.
// Find out which LOV input triggered the event.
String lovInputSourceId = pageContext.getParameter(SOURCE_PARAM);
// Find out the result values of the LOV.
Hashtable lovResults =
pageContext.getLovResultsFromSession(lovInputSourceId);
if (lovResults != null)
// Update the page depending on the value chosen by the user.
see if this helps....

How To Print Field Value in TOP-OF-PAGE During Line Selection when double click on field.
(If my memory serves me well (not used for long time ago)
Assign values to system fields sy-tvar0 - sy-tvar9, they will replace the placeholders "&0" through "&9" in the list headers and column headers.

In BADi , How to pass the values between two Method
Hi Experts,
We have two methods in BADis. How to pass the value between two Methods. Can you guys explain me out with one example...
Thanks & Regards,
Sivakumar SHi Sivakumar!
Create a function group.
Define global data (there is a similiar menu point to jump to the top include).
Create one or two function modules, with which you can read and write the global data.
In your BADI methods you can access the global data with help of your function modules. It will stay in memory through the whole transaction.

How to add field value to the standard table
Hi,
How to add field value to the standard table?
for example:
when we go to TCODE SE16-> VBAK table -> on the selection screen if we press F4 against VBTYP we get all the available values for that field. How to add a new document Category value to this field so that it shows up in F4 help for that field.Hi Asif,
I don't think it is possible and feasible for adding new field value to the field VBTYP because it is not possible through SPRO.
If u see the domain of this field VBTYP we have fixed values provided by SAP. There is no value table for this. If u have value table then it will be updated through SPRO. But still if u really want to add some value u can do that by getting access key and add the value in the fixed values of the domain. But of no use other than simply displaying in F4. Because for what ever value u created here there will be no documents in VBAK or any table using this domain.
Hope this is clear for u.
Thanks,
Vinod. -

How to set field value in workflow SPD2013?
Hi All,
how to set field value in workflow SPD2013? Actually using Infopath, i need to update a field value through workflow.(Little differnt from SPD2010). How to do this?As Amit says, some elaboration here would be good. You can use InfoPath as a form for either a list or a library and then set it to trigger a workflow upon item creation. The workflow will consist a number of actions, one of which is the Update
Field Item.
More information on the available steps can be seen here.

How to give two values of same field in read Statment
Hi,
Please Tell me how to give the two values of same field in read statements Condition.
i.e
Read table it_tab with key matnr = '1' or matnr = '2'.
With Regards
KesavaperumalHi Kesavaperumal,
<li>You can not use OR operator with READ TABLE statement.
<li>You have to use different fields of the internal table in where condition.
<li>If you want to compare with two values, you need to use LOOP statement.
LOOP AT it_mara WHERE matnr = '1' or matnr = '2'.
"Write code
ENDLOOP.

How to copy field comments from logical model to relational one?
Dear gurus!
I had a logical model without field comments. Then I made an engineering of logical model into relational one. Later I added field comments to logical model. How can I copy these values to relational model? Seems to me that when I use
model.getTableSet().toArray()
then I get list of relational model tables. How can I get a list of logical "tables" and to get a relations between those two lists?
Thank you!

Edited by: user12947051 on 12.01.2012 23:58You don't need to write and run script for that. Just use engineering to relational model. Use compare/copy options tab if you don't want something else to go into relational model

How can I share values between different jsp pages?
Hi,
I'm doing a jsp, bc4j application (JDeveloper 9.0.3), and I need to share some values between different jsp pages. To do this,
I have used the tag <jsp:usebean.....></jsp:usebean> in this way:
on pageone.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
on pagetwo.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
and so on, in order to refer to the same instance of the class "Parameters".
After deploying, the application works well only if the client is the same pc where the AS resides, otherwise the variables of "Parameters" are null.
Please, could you help me?
Thanks
Nunzio.I am seeing an indication on 9.0.3 that static includes are not static, but instead always dynamic. The compiler generates a call to the included page, and doesn't include the content in the calling page as it should.

How to copy field groups when editing a form?
Hi everyone,
I´m setting up a form using Acrobat X Pro. When I copy paste fields, they end up in the same field group. Could anyone tell me how to copy groups?
In my case, I would like to copy the answer options from one question, using them as the answer options for the next question.
Any idea?
Thanks a lot!!
AndyThank you!
I still hoped that there would be an easier way - also the Radio Button Choices change in weird ways once I change the name...
If there is still anybody who has a better way of going about this - please send a quick message.
Thanks again and best wishes -
