How to call events on a Dialog in Ax2012

I found a way in which we can override the form  events like modified, lookup, clicked etc. on a Dialog. We used to create event method on a dialog by using  “FieldNumber_1_event”  format. I got a requirement in which I have to show the lookup for service orders on the basis of project id on a dialog. I did it in a following way  instead of  we used to do in Ax2009.

·         Overwrite dialogPostRun method and wrote the following code

public void dialogPostRun(DialogRunbase _dialog)

{

    FormRun formRun;

    super(_dialog);

    formRun = _dialog.dialogForm().formRun();

    formRun.controlMethodOverload(true);

    formRun.controlMethodOverloadObject(this);

    fsCtrlSmmActivityNumber = formRun.design().control(fbsCtrlSmmActivityNumber.id());

    fsCtrlProjCategoryId = formRun.design().control(fbsCtrlProjCategoryId.id());

    _dialog.dialogForm().formRun().controlMethodOverload(false);

    _dialog.dialogForm().formRun().controlMethodOverloadObject(this);

         // 2012-10-02 #18679 pgad: Project adjustments -->

    dialogServiceOrderId.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(ProjAdjustmentSplit, serviceOrderLookup), this);

    // 2012-10-02 #18679 pgad: Project adjustments <-- o:p="">

}

·         Here I have registered  event lookup.

·          Created one  static method serviceOrderLookup.

public  void serviceOrderLookup(FormStringControl   _formStringControl)

{

    boolean ret;

    ;

    ret = _formStringControl.modified();

    if (ret)

    {

        this.lookup(); ( this will call the lookup method on a ProjAdjustmentSplit)

    }

}

·         Now  it will call  lookup event automatically. We need not to handle this
