[Trinidad] Problem in PageflowScope - attribute's value available even after it is removed.

[dushyant agarwal <ag...@yahoo.co.in>]

Hi,
(In the following text, I am abbreviating Baccking Bean as BB)

 A JSF- Trinidad page (Page1.jsp, BB = Page1BB.java) has to be opened in a dialog. The page contains of a tr:outputText- id="txt", BB binding="txt". In its getter method  we have to set the value of the component  from an attribute-"ConfirmMsg" from the PageFlowScope.
 
If attribute's  value is found not null, then it is set on the component txt(say - msg1), otherwise a default value (say- msg2) is set on the component-txt.

After the value has been set, the attribute-"ConfirmMsg" is removed from the pageFlowScope as following:
RequestContext.getCurrentInstance().getPageFlowScope.remove("ConfirmMsg");

Within the same BB  (Page1BB) there is a static method which contains the code for programmatically
 launching the dialog of the same page whose BB it is.

Now another jsp page has two command buttons - submit and cancel , whose action methods are submitAction and cancelAction respectively.

In cancelAction I am calling the static method of Page1BB to launch a dialog containing Page1.jsp. As well as I am setting an attribute -"ConfirmMsg", in the PageFlowScope as following:
RequestContext.getCurrentInstance().getPageFlowScope.put("ConfirmMsg",msg1);

In submitAction, I am calling the static method of Page1BB to launch a dialog containing Page1.jsp. But I am not setting any attribute on PageFlowScope.

Step 1. Initially on clicking on "submit" a dialog is launched, which contains the default message-msg2. On returning from the dialog and Then on clicking on "cancel" again a dialog is launched with the message provided in PageFlowScope(msg1). 
Now in Page1BB, this attribute had been removed after its value was set on the component in
 the dialog.
Step 2. After returning again if we click on "submit" (not sending any params this time) the content in the dialog should be the default message (msg2) But it is coming as msg1- the value of the attribute that was removed.

However, if we clear the PageFlowScope inside the action method of the return button in the dialog page(by which we are returning from the dialog) then repeat steps 1 and 2 we get msg2 as desired in the dialog.

What might be the reason for this? Help please.

Thanks,
Dushyant
