ADF UI Shell Pattern- How to pass parameter to the called bounded taskflow?

Question

The sample Launcher class of the ADF UI Shell template has the following code:
    private void _launchActivity(String title, String taskflowId, boolean newTab)
      try
        if (newTab)
          TabContext.getCurrentInstance().addTab(
            title,
            taskflowId);
        else
          TabContext.getCurrentInstance().addOrSelectTab(
            title,
            taskflowId);
      catch (TabContext.TabOverflowException toe)
        // causes a dialog to be displayed to the user saying that there are
        // too many tabs open - the new tab will not be opened...
        toe.handleDefault();
    }How do I pass a parameter to the bounded taskflow that will be launched?
For example:
1) I have a list of employees displayed on a tab.
2) When I select a record and click an edit button inside the tab, A separate tab should open with the corresponding employee to be edited.
How then could I pass the employee id to the edit-employee-task-flow?
I can't think on how/what would a "calling taskflow" come into this picture?
help!

Hi Arunkumar,
Thanks for the info. I was actually using EJB DataControls, and something similar to what you have suggested can also be done programmatically, but I wanted to follow the one promoted in the Fusion Developers' Guide to take advantage of the "ADF task flow framework" (like pass-by-value, pageflowScope, etc.) especially that we were having problems when we will just follow the procedures that was presented in the tutorials(I mean that- not all the procedures in the tutorials will work on an application based on the UI Shell pattern which do have multiple active taskflows.).
For instance, you have an active List of employees in one tab, and two other tabs that try to edit employee records. If these employee list and employee edit forms are based on a single iterator binding, then what would happen to the information in the two edit forms on each separate tabs if you selected another row on the employee list tab? -- In our case, the edit tabs' values synchronized to the new selected row in the list tab.
There are sure many work-arounds for these, but I am looking for a cleaner, clearer, or best way to handle this scenario.
