MyEclipse version: Build id: 8.6.1-Blue-20101117

Created [fileName].umldi and [fileName].uml in [projectName]/docs/uml folder. Made a number of additions, updates, etc. over a two week period. Created Java Class diagram containing numerous packages, classes, data types, etc. in support of Sequence Diagram. For some reason when I attempted to open [fileName].umldi today, I received the following error message:

org.eclipse.ui.PartInitException: Model file [projectName]/[fileName].uml could not be located

The uml file is still located in the [projectName]/docs/uml folder as it always has been. The *.umldi editor is looking for the associated *.uml file in the project’s root folder for some reason. If I copy the *.uml file to the project’s root folder the *.umldi editor locates the *.uml file but is unable to save the *.umldi file. Is there a way to re-associate an existing *.uml file with a *.umldi file? This seems to happen after running out of handlers in the *.umldi editor. Any thots on your part would be most helpful.

Stack trace available upon request.

galstuk,

Can you please provide below details –
1. Can you copy and paste your installation details. Open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > Installation Details
2. Clear your .log file located at [your workspace dir]/.metadata/.log, replicate the issue and copy and paste the stack trace here
3. You mention you have made a number of additions and updates. Can you please elaborate more

Galstuk,
The UML2 editor should work fine when you have the two files (.uml and .umldi) files in the same location. Do you recall moving the file(s) (especially the .umldi file) to a different location before you came across this issue? After facing the issue, you mentioned that you moved the .uml file to the project root folder. Did you try moving the .umldi file too and then opening the editor? In addition, can you please check the error log for any errors.

In answer to support-joy’s question about additions/updates: See my original posting. I created a Java Class diagram and a Sequence Diagram based on the classes, interfaces, etc. in the class diagram. This took me over two weeks and I’m not quite done. There were ONLY additions/updates to the UML diagrams and NOT to MyEclipse plugins during this two week period.

By cc to support-neeraj: I did not move any of the files before the error occurred. The error message is telling me that the *.umldi editor can’t find the *.uml file in a location it never occupied. What I’m seeing is that the *.umldi editor somehow lost the reference to the *.uml file in the /[ProjectName]/docs/uml folder and is looking in a default location; the /[ProjectName]/ folder. I copied the *.uml file to the project root folder and the *.umldi editor found the file and opened up without incident. The trouble now, is when trying to save the *.umldi file, there’s another error:

Invalid URL “platform:/LandingPages.uml”.

So now, I’m unable to make any more changes or updates to my diagrams until I get this file reference mess cleared up. Please be advised that the files in the /[ProjectName]/docs/uml/ folder are under version control with Subversion and moving files around between folders is really not an acceptable option.

[David E. Baker, Jr]

The link between the two files appears to be maintained in [userWorkspace]\.metadata\.plugins\org.eclipse.ui.workbench\workbench.xml. In my case, the file contained the following entries:

.
.
.
<file factoryID=”org.eclipse.ui.part.FileEditorInputFactory” id=”com.genuitec.eclipse.uml2.ui.editors.MEUMLEditor” name=”SessionMgmt.umldi” tooltip=”[projectName]/SessionMgmt.umldi”>
<persistable path=”/[projectName]/SessionMgmt.umldi”/>
</file>
.
.
.
<file factoryID=”org.eclipse.ui.part.FileEditorInputFactory” id=”com.genuitec.eclipse.uml2.ui.editors.MEUMLEditor” name=”SessionMgmt.umldi” tooltip=”[projectName]/docs/uml/SessionMgmt.umldi”>
<persistable path=”/[projectName]/docs/uml/SessionMgmt.umldi”/>
</file>
<file factoryID=”org.eclipse.ui.part.FileEditorInputFactory” id=”org.eclipse.uml2.uml.editor.presentation.UMLEditorID” name=”SessionMgmt.uml” tooltip=”[projectName]/docs/uml/SessionMgmt.uml”>
<persistable path=”/[projectName]/docs/uml/SessionMgmt.uml”/>
</file>
.
.
.

It would appear that the file became corrupted during a save. I removed the first entry and the *.umldi file can now find the *.uml file just like before. However, I’m still getting the

Invalid URL “platform:/LandingPages.uml”.

error when saving. It appears that saves are working but the error message is annoying.
