      Hi

       

      I am developing an application PDF-Viewer

       

      I set annotations on my pdf document. My Pdf/javascript posts annotation list to html/javascript, html/javascript stores annotations into database through ajax.

       

      When I restart my application, html/javascript retrieves all annotation from database and posts them to pdf/javascript. So they are added on my pdf document

       

      Problem :

       

      My PDF pages are loaded later than HTML document and I had Html/Javascript error:

      postMessage is not a function

       

      For correct this error I wrote something like that :

       

      var a = (typeof myPDF.postMessage);

      if(a != 'undefined')

      myPDF.postMessage("test");

       

      Now It works but not all time, sometimes I have an error :

      Error calling method on NPObject

       

      I think that my pdf document is not entirely loaded

       

      Is it possible to signalilze from PDF that my document is ready?
