How To Set Justification Settings

Question

Hi,
I'm trying to set the justification settings of a paragraph using IJustificationStyle's different setter mehods but the paragraph does not reflect the change that I set into the setter methods. I can see using the IJusificationStyle->GetWordspace method that the value was changed.
I tried recomposing the wax using IFramelistComposer->RecomposeThruNthFrame() method after setting the values but still the paragraph won't reflect the change in values.
Any help is highly appreciated, thanks!

I wrote this code soemtime ago for CS4 it reverses the alignment of all the text in a textFrame but could easily be modified to operate on a paragraph.
//========================================================
// ReverseTextAlignment 
// Change the text alignment in the text frame from leftAlign to rightAlign or leftJustify to rightJustify.
//========================================================
void PageItemFlipper::ReverseTextAlignment(UIDRef textFrameRef)
    do {
        // get the text content UID
        UID textContentUID = kInvalidUID;
        InterfacePtr <IGraphicFrameData> frameData(textFrameRef, UseDefaultIID());
        if (frameData) {
            textContentUID = frameData->GetTextContentUID();
        IDataBase* database = textFrameRef.GetDataBase();
        InterfacePtr <IMultiColumnTextFrame> mctf(database, textContentUID, UseDefaultIID());
        if (mctf == nil) { this->logger->Error("Nil multi column text object."); break; }
        InterfacePtr <ITextModel> textModel(mctf->QueryTextModel());
        if (textModel == nil) { this->logger->Error("Nil text model object."); break; }
        // get the number of characters in the story. Theres always a terminating character so
        // if the character length is not greator than 1 say goodbye.
        int32 characterCount = textModel->GetPrimaryStoryThreadSpan();
        if (characterCount <= 1) { break; }
        // get the range of characters in the story
        int32 textSpan = mctf->TextSpan();
        TextIndex startIndex = mctf->TextStart();
        TextIndex endIndex = startIndex + textSpan;
        // Check if the frame displays the stories terminating character
        if (endIndex >= characterCount) {
            textSpan--;
            endIndex--;
        if (textSpan <= 0) { break; }
        RangeData tRange(startIndex, endIndex);
        InterfacePtr <IComposeScanner> composer(textModel, IID_ICOMPOSESCANNER);
        if (composer == nil) { this->logger->Error("Nil ComposeScanner object."); break; }
        IDrawingStyle* drawingStyle = composer->GetCompleteStyleAt(startIndex, &textSpan);
        if (drawingStyle == nil) { this->logger->Error("Nil DrawingStyle object."); break; }
        InterfacePtr <ICompositionStyle> compStyle(drawingStyle, IID_ICOMPOSITIONSTYLE);
        if (compStyle == nil) { this->logger->Error("Nil CompositionStyle object."); break; }
        // get the alignment applied to the text range
        ICompositionStyle::TextAlignment appliedAlignment = compStyle->GetParagraphAlignment();
        ICompositionStyle::TextAlignment newAlignment = this->GetNewAlignmentValue(appliedAlignment);
        // change the alignment (values see ICompositionStyle alignment enum)
        InterfacePtr <ITextAttrAlign> alignAttribute1(CreateObject2<ITextAttrAlign>(kTextAttrAlignmentBoss));
        InterfacePtr <ITextAttrAlign> alignAttribute2(CreateObject2<ITextAttrAlign>(kTextAttrAlignmentBoss));
        if (alignAttribute1 && alignAttribute2) {
            alignAttribute1->SetAlignment(newAlignment);
            alignAttribute2->SetAlignment(newAlignment);
            // create the command to set the alignment attribute
            InterfacePtr <ICommand> alignCmd(Utils<ITextAttrUtils>()->BuildApplyTextAttrCmd(textModel, startIndex, (uint)textSpan, alignAttribute1, kParaAttrStrandBoss));
            if (alignCmd == nil) { this->logger->Error("Nil alignment command."); break; }
            InterfacePtr <IApplyStyleData> cmdAtts(alignCmd, UseDefaultIID());
            cmdAtts->GrabOverrides()->ApplyAttribute(alignAttribute2);
            ErrorCode result = CmdUtils::ProcessCommand(alignCmd);
            if (result == kFailure) {
                this->logger->Error("Reversing alignment failed...");
    } while (kFalse);
Hope it helps.
