I have created E/R diagrams using the DB explorer. I save the diagrams to a *.mer file. When I exit Eclipse and re-start, when I click on the *.mer file in the package explorer, I get a blank panel. If I right click choose to open the file with the text editor, I can see the XML file that names the tables that I had included in the the E/R diagram, but there is no diagram any more.

I’ve tried re-attaching to the DB in the DB explorer before opening the file, and this has no effect.

I created the ER diagrams using the “new ER Diagram” option from the DB Explorer perspective.
I’ve experience the same problem with ER diagrams created while attahed to Oracle XE and Postgresql.

Steve,

This this is an odd issue – I’m going to ask you to help track this down.

1) Create a sample ERD. Close it. Open it without restarting eclipse – does it show up?

2) Make some changes in a brand new ERD, save it – are there any errors logged?

If both the above work as expected, then
3) Make a copy of the file before shutting down eclipse, when you start it up again – compare this with the orignal mer file – are they the same? (I’m quite sure they will be, but just checking).

4) Do you have any special characters in table or column names?

When you atttempt to reopen the ER diagram, please have a look at your error log and paste the contents here. Instructions on getting a good log are available here: [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL]

Best,
Brian.

Brian,
When I restarted Eclipse after having left the ER diagram open, I noticed this error in my terminal window that I used to start Eclipse:

org.eclipse.core.internal.resources.ResourceException: Resource is out of sync with the file system: /capitalVision/problem_test_01.mer.

So I just hit f5 (refresh) on the project and now all the *.mer files open with no problem.

Thanks ,

Steve
