Bug Reports Archive (2009-2012)

When I paste I get an object reference not set to an instance of an object exception. Other diagram types seem similar

Platform tested: Linux.

Mono versions: Mono JIT compiler version 2.6.3 (Debian 2.6.3-2 ~ dhx1) / Mono JIT compiler version 2.4.4 (Debian 2.4.4-1ubuntu4 ~ svn151842).

Problem: When deploying the submenu "Add Diagram" from option "Project", the program crash and closes.

Thank you very much!

I just download the new version. I again repeat the action that caused the crash of the application and error persists.

When I go to: Project-> Add diagram, the menu tries to pop up but it does not and the program crash.

This might be very well the case. Mono is getting better and better, but it still is buggy. I also have applications, which run great on Windows/.NET, but fail on Linux/Mono. Debugging applications on Linux with MonoDevelop is also not as easy as it is with Visual Studio on Windows...

If you are able to reproduce the bug in Mono using a small peace of code, you can send the bug report to them and it will be fixed. I did that with my application and they fixed it in 15 mins. Mono IRC channel is a good place to get in touch with Mono devs.

P.S. Great job! Keep it up!

P.S.2 Is it normal that the *.simp file has tons of null or '\0' bytes at the end after </sim-project>?

I confirm this bug. All works great on Windows but crashes on Linux.

From what I have seen so far it is already a great tool and it has the potential of becoming even better.

Pros:

- Its C# and I love C#

- Its fast (much faster than other Java crap)

- You put a lot of effort to make the diagrams nice looking (not just rectangles, but shadows, gradient colors, etc.)

Cons:

- You probably noticed that GDI is not the best thing, when it comes to drawing and moving around large objects

Suggestions:

- Release the code as open source (the code itself is visible anyway in .NET Reflector)

- Start a bigger forum (phpbb, smf, etc.)

- Start a bigger bug tracking system (Bugzilla, etc.)

- Use other people to help you with things listed above (I am willing to help if you are interested)

Best wishes,

It might be helpful to release the code. I love this tool and I think could be improved much more among them. In addition also could help in the translation of more languages (Spanish, for example). I hope the bug is fixed.

Hi. First I must join in to say really good work with the program!

I've got two reports about trouble with copy and past, both for UI diagrams (v 3.35, WinXP sp3).

1. If grouping a rectangle and a text and try to copy and past this object I get a SerializationException, Type SoftwareIdeasModeler.Commands.Mementos.LocationSizeMomento has not been decleared as serializable

2. If having several UI diagrams and trying to copy a window with some buttons and comments from one diagram to the other I run in to the following exception when trying to save the project:

System.NullReferenceException: Object reference not set to an instance of an object.

Hi,

I've found problems when using copy and paste object several times, each time when using the copy Ctrl+ C and Ctrl+ V

program will hang for 1 minute as every time (if drag from template are normal)And the last show error message about memory.

"Object cannot be serialized.System.OutOfMemoryException:Exception of type 'System.OutOfMemoryException:Exception' was thrown.

FYI,I use SIM 3.35

I use WinXP SP3.

I'm not sure the number of times. But I working for about 5 hours with mix diagram

if object used then i will use Ctrl +C and Ctrl+ V (about 1 or 2 Object).

Today I tested. Again to inform but not found problem

I think that may be caused by working too long. And I will try to collect information and inform you once again.

finally,I may have forgotten to tell you that your program is a very great tool.
