Body
I am getting this error: <code>Too many objects match the primary key oracle.jbo.Key</code> when I tried to search in some view object where the <code>primary key</code> is consists of more than one filed. Use-case: In <code>Jdeveloper 11.1.2.3</code> I have <code>Entity object</code> called <code>someTable</code> this table has three fileds <code>A,B and C</code> where the <code>primary key</code> is consist of tow filed <code>A and B</code>. I created tow different <code>View object</code> from <code>someTable</code> enity object which are <code>someTableVO1</code> and <code>someTableVO2</code>. Filed <code>A</code> in the view object <code>somtableVO1</code> is a <code>List Of Value(LOV)</code> and the data is coming form filed <code>A</code> in the <code>someTableVO2</code>. In application I have a searching page which contain a drop down list for filed <code>A</code> in <code>somTableVO1</code>. Based on some conditions the drop down list values is not static. The value of the drop down list is changeable based on a <code>select</code> query executed on <code>someTableVO1</code> and it is based on the thried filed <code>C</code> which is NOT part of the <code>primary key</code>. The page shows the drop down list with the correct values. But, I have a <code>ValeChangeListener</code> method which will be activated when ever the user select some value form the drop down list. The problem is: The error <code>Too many objects match the primary key</code> is occur when ever I am executing this method. Assumption: I think that the problem is with the multiple fields for the primary key. of curse there is a duplication in part of the <code>primary key</code> ( i.e in one filed <code>A</code> or <code>B</code>) but the combination of <code>A</code> and <code>B</code> is always unique. Notes: 1. I check the query by running it in <code>SQL Developer</code> and it is not showing any duplicate values. 2. I did not attach code, because I think the problem is not about (how to do) it is about (what to do). I hope the idea is clear

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
