ONETIME_WHERE property problem

Question

Hi ALL,
Forms 10g 10.1.2.0.2 and Win-XP sp2
I have a form , on it's When-new-form-instance trigger i wrote this code
Set_Block_Property('jourhead',ORDER_BY,'VOCH_NO');
Set_Block_Property('jourhead',DEFAULT_WHERE,'IDENT='||V_IDENT);
Where :
VOCH_NO is a varchar2 text item
v_ident is a number variable
I have a button in this form, i wrote this code for When-button-pressed trigger
Set_Block_Property ('JOURHEAD',ONETIME_WHERE,'VOCH_NO='||''''||V_PREV_record||'''');
EXECUTE_QUERY;
This code works fine but sometimes the form freezes at the line (execute_query)
Note, The form doesn't freeze if i wrote this line like this :
Set_Block_Property ('JOURHEAD',ONETIME_WHERE,'VOCH_NO='||V_PREV_record);
But this is not the case, it doesn't give the required result.
What is wrong in this code ?
Please help
Thanks

Hi Ade,
Before set item property the value is displayed right , and sometimes the form freezes before displaying the message (this may be for the same record).
Ade i noticed a very strange behaviour :
the following syntax freezes the form :
Set_Block_Property('JOURHEAD',DEFAULT_WHERE,' IDENT= '||FV.V_IDENT);
Set_Block_Property('JOURHEAD',ONETIME_WHERE,'VOCH_NO='||''''||V_PREV_record||'''');
However the following syntax doesn't freeze the form :
Set_Block_Property('JOURHEAD',ONETIME_WHERE,'VOCH_NO'||'='||''''||V_PREV_record||''''||' AND IDENT='||FV.V_IDENT);
Aren't the two syntax the same ??
I confused .
