Webdynpro context: (invalidate)

Question

Hi there,
My application consists of 2 DC's:
-a data DC in which all the data models are contained
-a bupa DC in which the models are used, and implementation of context, plugs etc are done
When I update a BuPa via my application the values are updated in the abap backend, but when I navigate my application the old values are still shown.
When I refresh the application, the new values are shown..
So what to do to ensure that the newest values are always shown?
I tried doing this with wdContext invalidate (so it will recall the supply function) in the following way:
public void TriggerBuPaMyAccounts( )
    //@@begin TriggerBuPaMyAccounts()
     myAcctsInput = new __Cernum__Crm_Bb_Bupa_Myaccounts_Input();
     myAcctsOutput = new __Cernum__Crm_Bb_Bupa_Myaccounts_Output();
     try{
          wdContext.nodeOutputMyAccounts().invalidate();
          myAcctsInput.execute();
     catch(Exception e){
          msgMngr.reportException(e.toString(), false);
          msgMngr.reportSuccess("error: " + e.getCause());
     myAcctsOutput = myAcctsInput.getOutput();
     this.wdThis.wdGetContext().nodeOutputMyAccounts().bind(myAcctsOutput);
    //@@end
But that didn't help. Did I do anything wrong or...? Any suggestions?
I would rather not use wdContext.reset, or is that 'safe'? If I had to implement that, where should I do it?
Thanks!
Kind regards,
Allan

Hi Allan,
The model defines which connections you use. One model (normally) has its own connection, which is used over and over again in one webdynpro application, as long as you do not close it.
You have to close the connection in the method where you change the data in the backend
Like this:
public void TriggerBuPaMyAccounts( )
    //@@begin TriggerBuPaMyAccounts()
     myAcctsInput = new __Cernum__Crm_Bb_Bupa_Myaccounts_Input();
     myAcctsOutput = new __Cernum__Crm_Bb_Bupa_Myaccounts_Output();
     try{
          myAcctsInput.execute();
             myAcctsOutput = myAcctsInput.getOutput();
             this.wdThis.wdGetContext().nodeOutputMyAccounts().bind(myAcctsOutput);
     catch(Exception e){
          msgMngr.reportException(e.toString(), false);
          msgMngr.reportSuccess("error: " + e.getCause());
     }  finally {
       DynamicRFCModel modelinst;
       modelinst = (DynamicRFCModel) WDModelFactory.getModelInstance(BuPaMyAccountsModel.class);
     modelinst.disconnectIfAlive();
    //@@end
Note: This code seems to read the data. I am talking about a finally clause when writing the data.
