هل لها طريقة في ال Adf ولو ليها طريقة هتبقى ازاي؟؟

من فضلكم لو حد يعرف يقولى محتاجها ضروري

شكرا

 

Dear,

 

many ways, let us suggest 2 ways.

 

1- in DataModel Projcect, handle it in EO impl of your entity object, in dodml method after super and prepare for dml to achieve this

2-in Interface, handle in Back Bean Method to make the required new update based on Page Definition Iterator

 

Enjoy !!

 

thanks dear but i'm beginner in adf and i don't know how to write code for this in example in dodml method, can u help me plz to write this code 

thank alot

Dear,

 

you have to study EO impl Triggers and Data model very well before going inside for theses technical points ..

 

thanks

thanx Eng Adel for reply i studied EO impl triggers and do this code

 

protected void doDML(int operation, TransactionEvent e) {

 

super.doDML(operation, e);

setFlag("1");

if (operation == DML_UPDATE) {

 

try {

getDBTransaction().commit();

}

rollback(); throw ex;

catch (JboException ex) { getDBTransaction()
. } } }

 

 

 

but when rin and pressing commit get this error 

java.lang.StackOverflowError

cannot be cast to java.lang.Exception

 

Could u help me plz.....

Dear ,

 

1- preferred to make your code before super.

2- u have to use super.preparefordml before checking operation == dml type.

3- don't use commit, it is wrong action in EO.

 

good luck

Thanks Eng Wael I did it successfully

السلام عليكم

ممكن تشرح ماذا عملت وامل وضع الكود بعد التعديل

مع التحيه

تفضل

protected void prepareForDML(int operation, TransactionEvent e) {
        
        super.doDML(operation, e);
        if (operation == DML_UPDATE) {                        
            
            setCallStat("1");
           
           
        }
    }
