Navigation Problem in forms 10.1.2.0.2 !!!

Question

Hi All,
when we create relation between master and child block then getting problem in navigation.
i assume that you have form with two block with relation and data then execute query then
start following step
0) make sure you set required = true for first navigation item of child block
1) you are in child block make some change on any item and make your cursor must not be on first navigation item.
3) commit the form
2) then click on master block and here make sure you are clicking on non current record.

Thanks Frank,
Yes Frank please follow the steps.
this is error explanation :
I have debug many times !!!
actually it is not error but funny behaviour !!
when you click on parent block on diffrent record then validataion trigger of first item of child block will fire. I do not why it is happening !!!
I removed the validation trigger and did required=true for first navaigation item of child block then also it's behaving funny.
This are the steps.
1) create form with parent and child block and make relation ship
2) insure that you put 2 record in parent and 2-2 recors in child for each parent record.
3) insure that your first navigation item of child block has required property = true
4) run your form fresh
5) from parent bloc execute query ( I hope child block is populate some records)
6) click on any record of child block and make changes
7) then commit your form.
now fun will start
8) click on parent block on any record which has child records and non current record.
9) then form should populate details for child instead of it behaves different as follows
you will find FRM-40202 : Field must be entered
your cussor will remian in child block;
your record will not change in parent block.
and child block will remail blank.
by debugging I found that problem is coming from this code of <Clear_All_Master_Details> procedure
-- Put cursor back where it started
IF :System.Cursor_Item <> startitm THEN
Go_Item(startitm);
Check_Package_Failure;
END IF;
when I remove this line
Go_Item(startitm);
then my problem is solved
But I do not know what is the other impact can be possible by removing this.
Hello Frank
I hope you will catch this error by this example.
