BlackBerry save checkbox state in persistent store - blackberry

Question

I have a login page (username,password fields) that has a checkbox 'Remember me'. If the checkbox is selected, the application is required to remember the username & password for next login. That is done and working fine. However I am finding it hard to save the state of the checkbox field, i.e. whether it is checked or not. I am saving the username/password through the following code:
if (persistentObject.getContents() == null)
{
persistentHashtable = new Hashtable();
persistentObject.setContents(persistentHashtable);
} else {
persistentHashtable = (Hashtable) persistentObject.getContents();
}
if (persistentHashtable.containsKey("username") && persistentHashtable.containsKey("password"))
{
username.setText((String) persistentHashtable.get("username"));
passwd.setText((String) persistentHashtable.get("password"));
}
If the checkbox is selected and login is successfull, username and password are saved through the following:
if(checkBox1.getChecked() == true)
{
persistentHashtable.put("username", user_id);
persistentHashtable.put("password", password);
}
I tried to save the checkbox state with the line below but that is incorrect.
persistentHashtable.put("checkbox", checkBox1.setChecked(true));
Can somebody please help?

RIM rapc.exe compiler does not support autoboxing (it works in java 1.3 compatibility mode), and then you need to wrap your boolean value to a Boolean class instance before saving it in a hashtable or passing it to persistent store.

Hey guys I managed to find a solution to my problem. I worked around by checking if the username field is empty, then the checkbox state should be 'unchecked' else it should be 'checked'. This is doing what I wanted. If anyone of you have a better way of doing this please do suggest. My working line of code is as below:
if(username.getText().length()==0)
{
checkBox1 = new CheckboxField("Remember me",false);
}
else
{
checkBox1 = new CheckboxField("Remember me",true);
}
false = unchecked , true = checked

Check box is used for user wishes , according to your code , If user have entered user name checkbox will be checked.
Your Code is bit complex , First you need to setcontent code to persistent in very last , once you set your hashtable . You are having a login screen so you must have a submit button.
Do like this on submit button event:
// to set persistent values
if(checkBox1.getChecked() == true)
{
persistentHashtable = new Hashtable();
persistentHashtable.put("username", user_id);
persistentHashtable.put("password", password);
persistentHashtable.put("checkbox", "true");
persistentObject.setContents(persistentHashtable);
persistentObject.commit() ;
}
// to get from persistent values
if (persistentObject.getContents() != null)
{
persistentHashtable = (Hashtable) persistentObject.getContents();
username.setText((String) persistentHashtable.get("username"));
passwd.setText((String) persistentHashtable.get("password"));
String boolval = (String) persistentHashtable.get("checkbox");
if(boolval.equals("true"))
checkBox1 = new CheckboxField("Remember me",true);
else
checkBox1 = new CheckboxField("Remember me",false);
}
