Thanks,

There is an update issue here. When I add/remove a condition to a job/task, it is not showing in the main gui.
I have to restart the client to see the changes.

Hi,

If I add Active Directory user, the name is filled in the User Permissions window in the Name column, like [AD] .......
If I close the User Permissions window and open it again, the column is empty (also in 7.6.0).

Erik

Hi,

When I start a FTP connection in the FTP explorer, the grid with all the events is showing the password.
I think this should be ****** just as all the other logs.

FTPS commandsent: PASS 123456789

Hi,

I have some issues with the flow / notification combination, seen here: different topic .

I hoped to see it was fixed in this version, but it's not.
I found 3 issue where I can break/crash the client:

1. create a wait task with a on complete flow with a file notification
clone this task like 20-30 times and the client will crash.

2. Use the API code I uses in the post i mentioned above to remove the notification flow. After some modifications the client chrashes:
I created the same task as above, cloned it 20-30 times and cloned the job a few times.

Erik, I experienced the client crashing with the same error (ClientError: Collection was modified; enumeration operation may not execute.) in 7.6.0 when updating a Delete Folder task. I originally posted that error to this forum and it was moved to the 7.6.0 forum. As you mentioned, this error has not been fixed in 7.6.1.

John,

if you can reproduce this in the Friday build of 7.6.1 then please export all your settings and tell us exactly how to reproduce this. You can send to support@visualcron.com

Hi,

Today I downloaded the latest build and did the following:

1. Created a wait task in a job with two modifications to it. 1) set to 1 second 2) added an on complete file write notification.
2. I cloned the task 20 times and the client crashed again.

3/2/2015 8:12:28 AM	Info	Saving Jobs (12)


The other thing I did is using the DLL's to iterate through the job-tasks and delete the on sucess file notification flow.
First I used the job with the 20 wait tasks in there and I cloned the job three times, so 60 tasks have the on success flow which I want to delete.
After running my code the carsh is still there:

The code I used to do this is the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using VisualCron;
using VisualCronAPI;

namespace VC_changeFlow
{
    class Program
    {
        static void Main(string[] args)
        {
            Server s = null;
            Client c = new Client();

            Connection conn = new Connection();
            conn.ConnectionType = Connection.ConnectionT.Remote;
            conn.Address = "123.456.789.123";
            conn.UserName = "admin";
            conn.PassWord = "";

            try
            {
                s = c.Connect(conn, true);
            }
            catch (VisualCronAPI.Client.ClientLoginFailedException ex)
            {
                Console.WriteLine(ex.Message);
            }

            if (s.Connected)
            {               
                List<JobClass> jobs = s.Jobs.GetAll();

                for (int i = 0; i < jobs.Count; i++)
                {
                    JobClass job = jobs[i];
                    List<TaskClass> tasks = job.Tasks;
                    for (int j = 0; j < tasks.Count; j++)
                    {
                        TaskClass task = tasks[j];
                        List<FlowClass> flows = task.Flow;
                        for (int k = 0; k < flows.Count; k++)
                        {
                            FlowClass flow = flows[k];
                            if (flow.NotificationId == "91f0792a-92fe-4dd6-a709-b69abe784ea0")
                            {
                                task.Flow.Remove(flow);
                                s.Jobs.Tasks.Update(task);
                                Console.WriteLine(job.Name + " : " + task.Name);
                            }
                        }
                    }                    
                }
            }
            else
                Console.WriteLine("Not Connected");
          c.Disconnect(s);
        }
    }
}
