Process scope values get cleared randomly

Question

Hi,
In my backing bean i pass dynamic values as bind variables to a ViewObject
from the user selection screen form data.
I do this using ValueChangeListener method for each field.
In this method i put the current value in the processScope.
So in the pageDef file i give as:
<NamedData NDName="ContractTypeBind" NDType="java.lang.String"
NDValue="${processScope.contractType}"/>
<NamedData NDName="ContractPseNumberBind" NDType="java.lang.String"
NDValue="${processScope.pseNumber}"/>
After passing values like this, i have placed an LOV in the page so that it will populate dynamic records from the DB based on
the contract type and pse number entered by user.
If i use the LOV button for 3 -4 times randomly the process scope values are getting null.
I mean process scope values are getting lost.
why is this happenig can any one tell?
Thanks,

Hi,
I tried without using any valuechange listener and its absolutely working fine.
No need of putting any values in processScope and blah blah!!
I am passing values in backing bean for the ExecuteWithParams this way:
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("ProcurementLOVParams");
Map map = operationBinding.getParamsMap();
map.put("ContractTypeBind", conTypeChoice.getValue().toString());
map.put("ContractPseBind", pseNumber.getValue().toString());
Object result = operationBinding.execute();
And this is working fine..
