Cannot create diagram #2714

Closed kquick closed 2 years ago

kquick commented 2 years ago

Summary When attempting to "Create Diagram..." or "Open Diagram" from right-click menu in a .aadl file, I get a popup "Error creating diagram: null argument: " and no diagram is created.

Expected behavior The ability to create a diagram or better information about why I cannot create one.

Actual behavior Above

Steps To Reproduce

  1. File open test.aadl (see below)
  2. Right-click in test.aadl and select "Create Diagram..."
  3. See error
package test
public
end test;

Note that this happens for any AADL file, the above is the minimal example for reproducing the problem.

Desktop (please complete the following information):

Additional context Performed $ sudo apt install openjdk-8-jre and downloaded https://osate-build.sei.cmu.edu/download/osate/stable/2.9.2/products/osate2-2.9.2-vfinal.linux.gtk.x86_64.tar.gz, unpacked, and executed the osate executable from the unpack.

I tried in an Ubuntu VM (20.04.2) with Java 8 and cannot reproduce the error. Do you have anything in the error log (open with window > show view > other > general > error log)?

kquick commented 2 years ago

The errors in the error log are: Command 'org.osate.ge.commands.creatediagram' failed (Plug-in org.eclipse.e4.ui.workbench) org.osate.ge.internal.ui.handlers.CreateDiagramHandler.execute(): Error creating diagram (Plug-in org.osate.ge) org.osate.ge.internal.ui.handlers.CreateDiagramHandler.execute(): CreateDiagramHandler Started (Plug-in org.osate.ge)

Note that only the bottom-most appears after selecting the Create diagram... button. When clicking on OK in the error dialog, the next two lines appear above the bottom-most line.

How do you open the aadl file? Is it in an AADL project that is visible in the AADL navigator?

kquick commented 2 years ago

Generally just "File -> Open" and select the .aadl file, then in the .aadl contents in the main window, right click and select "Create diagram...".

That explains it. In OSATE we generally assume that AADL files are organized in projects in a workspace. This is inherited from Eclipse, on which OSATE is based.

If you are not familiar with these concepts see the Getting Started guide: Help > Help Contents, then expand "OSATE Core Documentation" and select "Getting started"
