To handle Exception in CO and AM from navigation to Next option

Question

Hi..
I have built one OA page..
I have used follwing code throw new OAException("PER","<Message_Name>",null,OAException.INFORMATION,null);
It gives error as
Information - Unexpected Error. Contact System Administrator
and allows user to go ahead.
But this error doesnt stop from navigatin.Its just like FYI.
Can I use throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getName(), // EO name
getPrimaryKey(), // EO PK
"OverTimeType", // Attribute Name
ReturnValue1, // Attribute value
"PER", // Message product short name
"Message_Name"); // Message name
But getEntityDef().getName(), getPrimaryKey() cannot be used from co.
I want to stop user from navigatiing till it changes the value to resolve the error.
Same happens when I throw error from AM.
I want that when user enter date, and it is invalid, then immeditaely he should get an error and he should not be ablt to move on next tab until it enters correct and valid date..
Plesae let me know if anyone has done same
Thansk in advance,
Nisha

Hi..
Thanks for help.
For some cases I am validating at attribute level so am throwing error at EO level. But at EO level also, say I have 5 fields, in which first field is date. I have put one validation in EO if eneterd date is after sysdate then I ma throwing error as
if (startDate > sysdate)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getName(), // EO name
getPrimaryKey(), // EO PK
"TripFrom", // Attribute Name
value, // Attribute value
"PER", // Message product short name
"HG_HR_OT_MSG_15"); // Message name
} where startDate is entered date.
Here If I enter invalid date then it doesnt throw erroe immediately, it allows me to enter details in other fields and when I click on submit buuton, which stores data in database , it throws error.
Is there any way by which I can throw erro immediatley after entering invalid value and it doesn not allow me to go on next filed till i enter correct value in first field.
