When I select “Create ER Diagram” after right clicking on a database in a DB Browser, It asks for a .mer file, and acts like it executes normally, but the .mer editor that comes up is empty (filled with the window background color), and the following errors appear in the .log file:

This is followed by more messages much the same (27K file length on a cleared log). Any ideas?

Thanks,

MyEclipse 4.0 requires the final release of Eclipse SDK 3.1. It looks like you are using an earlier integration build and it is causing a SWT problem. Download the Eclipse SDK 3.1 from here
http://eclipse.org/downloads/index.php and then install MyEclipse 4.0 onto that and you should be good to go.

Greg,

Re-installed Eclipse with a fresh download (Version: 3.1.0 Build id: I20050627-1435). Now I get an ER diagram with just the table boxes, but no relationship info. The primary and foreign key fileds are marked as such in each table, but no connector lines between tables and no errors in the .log file.

Are the relationship lines something that has to be turned on in 4.0GA?

Thanks,

Tom

Tom,

No, nothing has changed in the ERD in 4.0GA, was it working for you in 4.0M3 or any previous version?

It is really surprising that you see the table nodes *with* PK and FK information and yet no relationship lines, the common reason for this is the lack of FK information.

1) Check your ERD color preferencces.
2) Are you recreating your mer file from scratch or using an existing one? I assume you are doing the former, but just checking.
3) Are you sure you see FKs marked in the ERD? PKs and FKs are both marked with key icons, the PK icons aren blue while FK icons are yellow.
4) Are all relationships within the same schema? Or do you have cross schema relationships, in which case the relationships might not show up in the diagram.
5) What database and database driver are you using?

Let us know and we’ll get this issue sorted out.

Best,
Brian.
