[rules-dev] Activating the rule

[pchenna]

I have a rule while calls doMenu to display options and modify data
accordingly.But why this rule is getting called only once even thought
"WHEN" condition is matching.Isn't it should be called every-time condition
matches?

rule "Check trans"
	dialect "java" 
	when
		exists(Account())
	    $account :Account()
	then
		doMenu($account,drools.getWorkingMemory());		

end

rule "Credit"
#some code here
end rule

rule "Debit"
#some code here
end rule


function void doMenu(Account account,WorkingMemory wm) {
	
	String option = "1";
	//while(!option.equalsIgnoreCase("3")){

	option = JOptionPane.showInputDialog("1.Debit \n" +
						"2.Credit \n" +
						"3. Exit");
	
	if(option.equalsIgnoreCase("1")){
	
		String amount  = JOptionPane.showInputDialog("Enter Amount to be
Debited");
		double amt = Double.parseDouble(amount);	
		Transaction t = new Transaction ( account, amt, Transaction.DEBIT);
		wm.insert(t);
		
		
	}else if(option.equalsIgnoreCase("2")){
	
		String amount  = JOptionPane.showInputDialog("Enter Amount to be
Credited");
		double amt = Double.parseDouble(amount);	
		Transaction t = new Transaction ( account, amt, Transaction.CREDIT);
		wm.insert(t);
	}
	
//}			
}

Sorry if this question is very naive,tried searching in forums and couldn't
find anything helpful.
