File attachment is not opening – Not Allowed Error

[tonydaes]

Hi,

this is my first attempt to prepare a dynamic form in Livecycle Designer ES4. In this form, there is an option to add and view attachment. As I have little experience in javascript coding, I went to the adobe forum and found a very good example posted by Bruce in https://forums.adobe.com/thread/2517255. Thanks to Bruce.

I made some adjustment in the code and my final code looks like below-

//Code for add button
form1.page1.ImportDataObject::click - (JavaScript, client)
// Get Import Name
var cName = AttachName.rawValue;
// Test for empty value
if(!/^\s*$/.test(cName))
{// Do Import
   try{
     var bRtn = event.target.importDataObject(cName);
     if(bRtn)
     {
        var cDesc = AttachDesc.rawValue;
        if(!/^\s*$/.test(cName))
        {
            var oAtt = event.target.getDataObject(cName);
            oAtt.description = cDesc;
        }
        app.alert("File Attachment Successfully Imported",3);
     }
     else
        app.alert("Unable to import File Attachment",0);
   }catch(e){
     app.alert("An Error Occured while Importing the File Attachment:\n\n" + e);
   }
}
else
   app.alert("Attachment name must be non-empty");
//code for dropdown list
form1.page1.AttachNameSel::preOpen - (JavaScript, client)
this.rawValue = null;
this.clearItems();
var a = event.target.dataObjects;
if (a !== null) {
for (var i = 0; i < a.length; i++) {
this.addItem(a[i].name); 
}
}

//code for open button
form1.page1.ExportAttach::click - (JavaScript, client)
//code for export attachment button
var cName = AttachNameSel.rawValue;
//var nAction = ExportAction.rawValue;
    try{
    event.target.exportDataObject({cName:cName, nLaunch:2});
    } catch(e) {
      app.alert("An Error Occured while Exporting the File Attachment: " + cName + "\n\n" + e);
    }

With the above code, I can attach file successfully. But my problem is that when I want to open file attachment in Acrobat Pro XI, it is showing below error instead of opening the file. This error is showing independent of file attachment type (I tried attaching doc, txt and pdf file).

Any help from anyone in the community would be greatly appreciated.

Thanks

The script is fine, the problem at you end seems to be the attached file itself. Acrobat exports only a handful of file types (PDF, JPG, PNG …), all others a blocked for security reasons, so noone simply could run an evil executable attached to a PDF. You screenshot states that your file "GPD" doesn't have any file extensions, so Acrobat of course blocks it.

Hi Radzmar,

Thanks for your reply.

My file GPD is a .doc file. I checked the code in Acrobat Pro DC and attachments are opening without any problem. Now I am using below code so that acrobat pro XI user can open file by selecting from navigation panel.

if((app.viewerVersion)<12){event.target.viewState = {overViewMode:7};}
else {
//code for export attachment button 
var cName = AttachNameSel.rawValue; 
//var nAction = ExportAction.rawValue; 
    try{ 
    event.target.exportDataObject({cName:cName, nLaunch:2}); 
    } catch(e) { 
      app.alert("An Error Occured while Exporting the File Attachment: " + cName + "\n\n" + e); 
    }
}

Thanks
