Hi, I could able to resolved bit as, on my java script call i m passing the record id as :
onclick="javascript:tstconfirm('${recordInfo.getId()}');"


and java script method written as :

function tstconfirm(recId){
smoke.confirm('Are you sure you want to delete this record?',function(e){
if (e){
smoke.alert('Confirmed');
alert(recid); // This place I am able to get the correct record id
// here i can call the ajax function to delete the record.
}else{
smoke.alert('Canceled');
}
});

Now issue i am facing is alert "Confirmed" and alert(recid) display simultaneously, at this point browser not waiting Confirmed event from user, it goes ahead and print alert(rec id) too. It means that record gets deleted without user select "Confirmed". what if user decide to not to delete it using "Esc" button from key board.
}

I have to exposed a REST service, This service will take json string and then it will verify against the json schema, to check if input json string confirms the json schema. If input json string confirms the schmea then i have to create a asynch thread which will process the json data.

Please guide , how can i perform following:
1. After validation is done, then I have send "Accepted" Message.
2. After validation is successful, create a asynch thread which will be process my json string.

I have seen the concurrent modification exception normally thrown if a Collection is modified while an Iterator is iterating through it.

I was able to receive concurrent modification exception when i executed below code, as i was iterating the list and was removing the item from list:

But once I commented the code to remove item from list and added a line which add a item in the list, I did not received the exception:




Does concurrent modification exception always comes when we Iterator a collection and removes an item from it? Not in case of addition .

Hi,

I have an application implemented using Adobe Flex. After login into the application from multiple browser, I can see each time a new session created which is a correct behavior as for our requirement.

I am using java console to check the session information.

Once I launch my application, I verify that in TaskManger i found that javaw.exe instance gets created. But when I log out from the application javaw.exe instance remains appears there in task manger and keeps eating the system resource.

My question is :

1. Does javaw.exe instance maintaining the session information at client end?
2. programaticlly how can I kill javaw.exe instance on logout?

Thanks,
