JavaScript, Saving, temp file

Dear friends,

I need to edit a PDF file in Acrobat Reader and save it afterwards under the same name and location. The file is called by a DMS-App as a temp-file. I wrote a code for saving and closing:

// Meue Item

app.addMenuItem( { cName: "mySaveDoc", cUser: "Direktspeichern",

cParent: "File", cExec: "mySaveDoc(this, this.path)",

cEnable: "event.rc = (app.doc != null);",

nPos: "Open", bPrepend: true } );

//Function for saving the doc

var mySaveDoc = app.trustedFunction(function(oDoc, myPath){

app.beginPriv();

oDoc.saveAs({cPath: myPath, bPromptToOverwrite: false});

oDoc.closeDoc(true);

app.endPriv();

});

The code works fine but not for the temp-files, I get a message of ‚write protection / doc used by onother user‘. But I can navigate to the temp-file in the „Save As“ dialog box and save it manually without any problems.

Please, could you give me advice what I could try?

Thanks, Markus
