Two views on one entity

Question

Hi,
I am using ADF. I have one entity with one attribute called Attr. I´ve created two view objects on this entity. Let´s name them v1 and v2 and there row objects v1row and v2row
When I execute v1row.setAttr and commit the transaction the call to v2row.getAttr returns the original value and not the new one. In my opinion this happens due to the caching mechanism.
How can notify all views that there underlying entity has changed?
Thanks!
Regards,
Christian

I implemented two changes:
1. Disabled database trigger
2. replaced validate/postchanges with commit
myAm = getNotificationImplApplicationModule();
Test1ViewImpl v1 = myAm.getTest1View1();
Test1View2Impl v2 = myAm.getTest1View2();
Test1ViewRowImpl v1row;
Test1View2RowImpl v2row;
System.out.println("executeQuery for both views");
System.out.println("table has exactly one row");
v1.executeQuery();
v2.executeQuery();
System.out.println("navigate to first row of view 1");
v1.first();
v1row = (Test1ViewRowImpl)v1.getCurrentRow();
System.out.println("V1, before setVt1:" + v1row.getVt1());
v1row.setVt1("changed text through v1");
System.out.println("V1, after setVt1:" + v1row.getVt1());
System.out.println("commit changes to database");
myAm.getDBTransaction().commit();
System.out.println("navigate to first row of view 2 without requery");
v2.first();
v2row = (Test1View2RowImpl)v2.getCurrentRow();
System.out.println("V2 without requery:" + v2row.getVt1());
System.out.println("now requery view 2 and navigate to first row");
v2.executeQuery();
v2.first();
v2row = (Test1View2RowImpl)v2.getCurrentRow();
System.out.println("V2 with requery:" + v2row.getVt1());
The result now is:
04/07/26 10:24:20 executeQuery for both views
04/07/26 10:24:20 table has exactly one row
04/07/26 10:24:22 navigate to first row of view 1
04/07/26 10:24:23 V1, before setVt1:initial text in database
04/07/26 10:24:24 V1, after setVt1:changed text through v1
04/07/26 10:24:24 commit changes to database
04/07/26 10:24:25 navigate to first row of view 2 without requery
04/07/26 10:24:26 V2 without requery:initial text in database
04/07/26 10:24:29 now requery view 2 and navigate to first row
04/07/26 10:24:53 V2 with requery:changed text through v1
As you can see view 2 still gives the initial value without requery.
