Facility Control

I'm having trouble using ogscript.asyncFTPListFiles. I can successfully connect to the FTP server, but the returned fileList variable is empty. I know the FTP is connecting since I'm monitoring the server. I just used the example code included in the Dashboard Script Palette. I can't find any documentation on this function in the ogScript reference doc.

Here's the code I'm using:

/* fileList consists of an array of org.apache.commons.net.ftp.FTPFile */
var fileList;

function callback(success, fileList, exception)
{
if (success) {
ogscript.debug("FTP success");
}else{
ogscript.debug("FTP Fail!");
}
}
ogscript.asyncFTPListFiles('localhost', '21', 'username', 'password', '', callback);
ogscript.debug(fileList);

I would verify that you have valid files at the default directory for that username/password or try manually-specifying a path. I have just verified the following code snippet against one of our local FTP servers:

function outputResults(success, files, exception)
{
   if (!success)
   {
      ogscript.debug("NO SUCCESS");
      return;
   }
   else if (files != null)
   {
      /*
       * files[i].getName()
       * files[i].getTimestamp  // returns java.util.Calendar
       * files[i].getSize()     // returns file size in bytes
       * files[i].isFile()      // returns true if the file is a File (not a directory)
       * files[i].isDirectory() // returns true if the file is a Directory
       */
      ogscript.debug("GOT " + files.length + " FILES");
      for (var i = 0; i < files.length; i++)
      {
         var jsTime = (new Date(files[i].getTimestamp().getTimeInMillis()));
         if (files[i].isDirectory())
         {
            ogscript.debug("GOT DIRECTORY: " + files[i].getName());
         }
         else
         {
            ogscript.debug("GOT FILE: " + files[i].getName() + " " + jsTime);
         }
      }
   }
}

That works, thanks! I think I wasn't reading the array properly, so it looked like nothing was getting passed.

Another question, since it seems asyncFTPListFiles isn't documented anywhere: Is there a way to recursively list directories? I can successfully list directories and files in the root level, and differentiate between them. I'm having a problem digging into each directory to list those files, too.

Basically I'm putting the directory names into an array, and the file names into another. Eventually I'm trying to populate a drop-down with file names in the format "directory/filename."

If the directory array length is more than 0, then I do another asyncFTPListFiles and repeat the process. The problem comes from the way I'm looping through all the directories. I'm using a for loop to go through the directory array and open a new FTP connection, using the name from the array as the directory to list.

if (dirList != 0){
      for (var a = 0; a < dirList.length; a++){
         var currDir = dirList[a];
         ogscript.asyncFTPListFiles(FTPip, 21, FTPuser, FTPpass, currDir, outputResults1);
      }
   }

Since the code is asynchronous, I can't use a variable in a for loop to mark what second level-directory we're listing, since by the time the second directory has been listed, the for loop has gone through all the other folders.

for (var i = 0; i < files.length; i++)     // files is the array returned by asyncFTPListFiles
   {
      constraintData.push(currDir + '/' + files[i].getName());  //Push the key/value pair
      
   }

Any thoughts? Thanks again!
