How to set transient value to persistent attribute at commit in View Object

Hi
I'm using JDev11.1.1.2
I have a transient atttribute X in my View Object and a persistent attribute Y. I want the value of X to be assigned to Y before commit.
I saw that the entity has a method doDML that is used for this, but the problem is that this transient attribute is in my View Object, not entity object.
Any ideas?
Thanks

Hi
My transient attribute has a groovy expression assigned. This expression is calculated from other attributes in the view object.
It seems that the setter method of the transient attribute is not called when the value gets updated through groovy.
I used a transient attribute that duplicates my persistent attribute because groovy expression on transient attributes are recalculated, and the groovy expression on persistent attributes are not recalculated - they are used only for default values.
Any other ideas are appreciated!
Thanks

How to set default value to user attribute in customized information tab

Hi Experts,
we created a custom attribute in Administration-managed custom attributes and now we are getting that attribute under customized information tab in user admin->identity management.
This attribute is coming for all users and it is working fine and I can give value to this attribute also.
Now the problem is we have more than 10000 users in the portal and we have to assign same value to this custom attribute to all the users.
Is there any possiblity of setting the value to all the user without coding.
If it is not possible then how can I proceed for coding.
any help will be appreciated.

Hi Michael,
Yes my data source is LDAP. This attribute is added in the portal itself and I don't think it is possible to set the value of custom attribute at LDAP.
Shanta : We already created the custom attribute and it is also appearing in the Customized information
Problem is we need to set a value to that attribute. This should be same to all the users coming from LDAP.
My Basis people are asking the funtion module which calls when we click on the Customized information tab. Is that possible to know?
Or we can set this value by writing a piece of code in webdynrpo java?
Appreciate your inputs

How to set default value to date type attribute.

Hi,
How to set default value to date type attribute.
E.g I want to set u201C01/01/1999u201D to date attributes.
First i want to set value and then i want to fetch the same & want to check equals.
please suggest solution.
Regards,
Smita

Hi,
In wdinit() method u can set the date
DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
Date today = Calendar.getInstance().getTime();
String reportDate = df.format(today);
wdContext.currentContextElement().setFromDate(reportDate);
Another way you have set the this formate like that
1. Create a Simple type under "Dictionaries->SimpleType" called DateFormat
2. Select the type as "date"
3. Go to the "Representation" tab and set the format as "dd/MM/yyyy" (or whatever u want, but month should be MM)
4.Bind the context attribute to the type created now.
Hope this helps u.

Self-referential attribute: how to set the value if it is NULL/unknown

Hi,
I am getting the following error while doing Logical Loop Check:
self-referential attribute: b5@Rules_test_doc
number of rules in this loop: 3
number of attributes in loop chain: 3
number of relationships in loop chain: 0
The rule engine will be seeded with information from a database.
My requirement is to set a value to the attribute (X) = "ABC" if (X) is null and (Y) is 0
( in 10.4 NULL is represented by unknown)

You would have to have an intermediate field here to achieve this. It definitely is a logical loop in OPA terms, since you are trying to use X to prove X.
To solve it you would need to do:
attribute (X) = "ABC" if (X_input) is null and (Y) is 0
Or for a "real" example:
the person's processing office:
"london" | the person's provided procesing office is currently unknown
the person's provided procesing office | otherwise
So if no processing office has been provided by the database, (i.e. "null") it effectively defaults to London.
You could then use "the person's processing office" as normal throughout the rules, confident that it should never be unknown.
Cheers,
Ben

How to set fixed value in doDML

Hi,
My application is ADFBC.
i am getting fixed value in backing_bean.this value is not coming form VO.how to set this value in doDML.because i want to save this fixed value(this value changing in backing_bean from UIpage) into database.
actually i am using fixed list box values(these are not from VO) in UIPage and after submitting i am getting this vaue in backing_bean and some updatable table is displaying in UIpage.after filling some values in the updatable table and i am pressing commit button then i have to set this value into one table in databse.
all updated values are saving because i am using ADF table.now i have to save this list value also in one of the column in this table.
How to set this value into doDML?
please help me.
Thanks,

Have you thought of creating a "transient" attribute in your EO or VO, that stores the fixed list box value? Then in the doDML method you could grab this attribute's value and update the other EO attribute you're interested in.
Alternatively in the transient attributes setter in the EO, you could write the code to update the other EO attribute.
Hope this helps.

Thanks in advance

Hi,
"cookie" is a reserved name. If you want to write to a session scope attribute called "cookie" then you have to call #{sessionScope.cookie}. If you want to use EL to set and read from cookies then you will have to use
#{cookie.cookieName}
Note that #{cookie} writes to and returns a map

How to define a Value for an Attribute of an Class

Hi,
How to define a Value for an Attribute of a Class ...
( I need to change the value of an Attribute of a class in standard program ....
Ex...
   cl_hrce_masterswitches=>infotype_framework_is_active
Here infotype_framework_is_active is the attribute .. its value in standard program is 'X'... Now i need to change it as ' '.
How to define it and set value as ' '.

Hello Surendar
The static attribute INFOTYPE_FRAMEWORK_IS_ACTIVE is read-only and there is not SETTER method to manipulate its value.
However, the attribute is filled in the CLASS_CONSTRUCTOR:
METHOD class_constructor.
    IF ce_is_active                 = true OR
       global_payroll_is_active     = true OR
       mngmt_global_empls_is_active = true.
      infotype_framework_is_active = true.
      perid_infotype_is_active     = true.
    ELSE.
      infotype_framework_is_active = false.
      perid_infotype_is_active     = false.
    ENDIF.
ENDMETHOD.
Thus, you need to analyze how attribute CE_IS_ACTIVE, GLOBAL_PAYROLL_IS_ACTIVE and MNGMT_GLOBAL_EMPLS_IS_ACTIVE are filled in the CLASS_CONSTRUCTOR.
For sure you will find customizing settings that are responsible for this.

How to set default values for boolean columns

I'm trying to deploy some content types and columns into a site with a feature. All it's ok, except that I'm trying to set a default value for boolean columns with no success.
I've tried to set default value at column level:
<Field ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DisplayName="Se publican noticias en español"
Type="Boolean" Hidden="FALSE" Group="Columnas ShaCon" >
<Default>TRUE</Default>
</Field>
and at content type level:
<FieldRef ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DefaultValue="TRUE" Required="TRUE" />
But in any case, when i create a new item with this content type, default value is applied.
Can anyone tell how to set default values for boolean columns?
Thanks in advance,

Sergio

In the field definition you can set
<Default>1</Default>
or
<Default>0</Default>

How I set a value to only parameter one of them , such as set
GoodsID when use mx:remoteObject.
Thanks for your help

Got maybe a solution for you, I have just tested it.
So, the idea is to use intermediate variables. Imagine Var1 and Var2 variables that you refresh with your more or less complicated queries. Then what you can do is to refresh your final variable Var3 with a query using your intermediate variables. Here is an example for Oracle:
select #Var1+#Var2 from dual
This way you can make a chain of dependent variables: Var3 is using Var2 and Var2 is using Var1.
Hope it helps.

How to set the value of something in a component from the main application?

Hi,
Maybe I've been working on this too long, but I can't figure
out how to set the value of the text property of a text input field
in a component from my main application in an mx:Script block. I
have a component called Login in the components folder, and I need
to set the text value of empNum. In my mxml declaration at that the
top, I've declared these components as xmlns:c="components.*" So
logically, the property I'm trying to set is c.Login.empNum.text. I
can't figure out the correct syntax to get this to work, and I've
tried everything I can think of. Does anyone have any suggestions?
I'm thinking this should be an easy one, and I'm just missing
something.
Thanks!
Holli

Did you try giving it an id ?
<c:MyLogin id="loginScreen" /c>
So later you can do loginScreen .empNum.text = "my text"
