PMString turning null on Mac

Question

Hi
I am developing a plug-in on Mac OS (10.5.8) using the InDesign CS4 SDK and for some reason, in my plugin project whenever i use a PMString, and assign value to it, it turns "nil". I am wondering if there is something in the project settings etc. that needs to be setup to fix this issue?
As an example, i use the following code to popup a saveFile dialog and get the file path into a PMString. (the SDKFileSaveChooser is part of the SDK)
    SDKFileSaveChooser SaveDlg;
    SaveDlg.ShowDialog();
    //save the document to disk
    PMString szFile(SaveDlg.GetPath());
    At this point, my PMString file has value nil when i look at it in the debugger.
PS: same code  that I created on windows works fine without any issue. I am able to get the filePath back without any issue.
thanks

the new displays can power up your desktop. it will only work if you plug in the firewire/usb cables from your monitor to your desktop, then go into the system prefs>displays and choose how you want the monitor button to behave. that option won't appear in the system prefs if you just have the dvi cable plugged in and not the firewire/usb cables
