OpenOffice save as dialog filter types

Question

Hello,
I have the below java method that displays a OOo save as dialog .
i have an issue with filter types in this save dialog: it seems the combo box type in save dialog doesn't contain the filters (like "OpenDocument Text") i appended in java method code below . when i click on type combo box the list is empty !
can someone point me what i'm i doing wrong ?
how to force the save as dialog to display all possible OOo types in 'type ' combo box ?
thanks much

hmm i solved the issue !
the trick is to move the filter appending code after call to initialize method :
so we must append filters last thing before calling execute to show the dialog !
so this code works :
xInitialize.initialize(listAny);
            // add a control to the dialog to add the extension automatically to the filename...
            XFilePickerControlAccess xFilePickerControlAccess = (XFilePickerControlAccess) UnoRuntime.queryInterface(XFilePickerControlAccess.class, xFilePicker);
            xFilePickerControlAccess.setValue(com.sun.star.ui.dialogs.ExtendedFilePickerElementIds.CHECKBOX_AUTOEXTENSION, (short) 0, new Boolean(true));
            xComponent = (XComponent) UnoRuntime.queryInterface(XComponent.class, xFilePicker);
             // set the filters of the dialog. The filternames may be retrieved from
            // http://wiki.services.openoffice.org/wiki/Framework/Article/Filter
            XFilterManager xFilterManager = (XFilterManager) UnoRuntime.queryInterface(XFilterManager.class, xFilePicker);
            //xFilterManager.appendFilter("OpenDocument Text Template", "writer8_template");
            xFilterManager.appendFilter("OpenDocument Text", "writer8");
            xFilterManager.setCurrentFilter("OpenDocument Text");
            // execute the dialog...
            XExecutableDialog xExecutable = (XExecutableDialog) UnoRuntime.queryInterface(XExecutableDialog.class, xFilePicker);
            short nResult = xExecutable.execute();
