Description:
I wrote small plugin which uses mforms module for few user interface wizards, while it worked okay in Windows with 5.2.18 version, it does not work on Linux Ubuntu with 5.2.25 version.

Error after workbench started with installed plugin in script shell:

..... line 16, in <module>
import mforms
ImportError: No module named mforms

I'm not sure if it has something to do with Windows/Linux difference, or version difference, but it successfully worked before.

How to repeat:
Just try to import mforms module in plugin code (I use python language)

Does the administration module work for you?
[14 Jul 2010 17:27] Igor Gladkov 
Yes, everything works in workbench itself, just my plugin isn't loading because of that error.
[15 Jul 2010 18:18] Alfredo Kojima 
Can you upload your plugin so we can try loading it ourselves?

Please see Alfredo's last comment. Thanks.

I uploaded strip-down version of the plug-in, which has the same type of error.

Should be something Linux-specific. On Mac OS X I've got no problem like you described after adding your plugin. This is what I see in scripting shell:

Ready.

What version of Python do you have on Linux?
[17 Jul 2010 16:00] Igor Gladkov 
Probably it's Linux specific, since it worked fine for me on Windows as well.

Python is 2.6

Hello Igor,

import mforms
ImportError: No module named mforms

Afair its mformat under Linux and not mforms.
[22 Jul 2010 0:39] Igor Gladkov 
Using mformat gives the same error as when I use mforms.
[22 Jul 2010 6:06] Susanne Ebrecht 
Is mformat installed on the system?
[22 Jul 2010 7:19] Igor Gladkov 
The only program I know in Unix named mformat is program for disk format, so I'm still not sure how mformat related to Workbench plugins.
Other than that, I assume that all modules needed to run Workbench plugins are installed with the program, the same as it works on Windows and Mac.
Mform is a module in workbench, which I see in the source code and in the installation directory, but it's not found for some reason.

I was able to repeat and fix the problem.

fix confirmed in release 5.2.28

An entry has been added to the 5.2.28 changelog:

A plugin which used Mforms generated the following error when MySQL Workbench started:

..... line 16, in <module>
import mforms
ImportError: No module named mforms
