stringedit.text(element.args().parm()) but nothing shows up

Hey all,

i have this code :

NOTE: i'm trying to pass one value from a field in Form A to a field in Form B.

in Form A, on button's clicked method :

void clicked()
{
    FormRun formRun;
    Args args;
    args = new args();
    args.parm(MyTableParent_MyID.text()); //from a datafield in Form A - Datasource sA.
    args.name(formStr(MyFormChild));
    formRun=ClassFactory.formRunClass(args);
    formrun.init();
    formrun.run();
    MyTableParent_ds.refresh();
    MyTableParent_ds.executeQuery();
    super();
}

in Form B, on init() form method :

public void init()
{
    str anycaller;
    super();
    anycaller = element.args().parm();
    if(element.args())
    {
        MyTableChild_MyID.text(anycaller); // -----> in here nothing shows up

//but if i change it into :

MyTableChild_MyID.text("anything about string here it shows up.");
}}

This very makes me headache, can anyone help? Why the field won't showing value from element.args().parm(); ?????? Thank you!
