    Re: Not able to upload some PDF files

    Here is an exemple of the problem. It's derived from simple-upload-UI.aspx.
     
    Modification of simple-upload-UI.aspx :
    The forms begins now with a simple button.
    All the old part of the form is placed into a MultiView/View.
    Initialy, the multiview have its visible attribute set to false.
    The callback of the first button sets the visible attribute of the multiview to true.
     
    Prolem with the new code :
    After the first clic on the button. the old form appear. OK 
    The first use of image upload is normal.  OK
    Now, the association of "InsertButtonID='Uploader1Insert'" is lost. NON OK
    The original text button of  Uploader1 appear. NON OK
     
    Code :
