Description:
On opening a diagram file tables layout is broken - all tables are placed on top-left corner.

It seems that application (at least its Windows version 5.0.30) stores diagram layout in file correctly but it's not retrieved on file load.

It's similar to http://bugs.mysql.com/bug.php?id=42329 but I've decided to file a new one since it's on different Platform.

How to repeat:
1. Save diagram with at least one table placed somewhere in the middle of the page.

2. Open diagram - table is placed on the top-left corner.

Verified as described on Ubuntu 8.10 64 bit.

Test:
Open Workbench
create a small diagram with two or three tables and two or three conditions
save it
close Workbench
Optional shutdown your computer, go sleeping
open workbench
open recent file your diagram

just my test diagram

I have the same problem running on a GNU/Linux Fedora 10
Kernel 2.6.27.19-170.2.35, using MySQL Workbench 5.1.7 

Anytime a diagram is opened, the layout it's changed and all the relations are plaece at the upper left corner of the panel.

workaround :
export and import

Hi

There is a workaround for this bug which is to set the LC_NUMERIC environment variable to C.
However if you saved the model file after loading into a broken state, the model layout will likely be 
really lost. If you didn't save after noticing the broken layout, your model layout will be intact.

Thank you for your bug report. This issue has been committed to our source repository of that product and will be incorporated into the next release.

If necessary, you can access the source repository and build the latest available version, including the bug fix. More information about accessing the source trees is available at

fix confirmed in bzr rev 3871.
fix will be include in 5.1.10 beta

Added an entry to the 5.1.10 changelog: 

On opening a diagram the file tables layout was broken. All tables were placed in the top left corner.

It appeared that Workbench stored the diagram layout in the MWB file correctly but it was not retrieved correctly on file load.

It looks like we have a regression here. After syncen or loading a database all is placed in left top corner.

Triage:

I think this is a serious problem. It will cost customers and users immense money to
re-order all the tables manually.

We should fix this before WB52 GA.

Let WB52 and set P2 and IO=100 because we have enormous user complains here.

Thank you for your bug report. This issue has been already fixed in our source repository of Workbench 5.2 and will be incorporated into the next release.

All works fine with Workbench 5.2.6.
