Trying to save QtiPlot entities to Nexus file causes exception

[Arturs Bekasovs]

When you try to save Table, Matrix, Graph etc. to a Nexus file you get an exception: Invalid input workspace for SaveNexus. Saving these things using SaveNexus is obviously impossible, however the File -> Save -> Nexus menu item is not disabled in that case.

On contrary, File -> Save ASCII is disabled when current object couldn't be saved to ASCII, e.g. when it's a Graph.

Moved to backlog at the end of Release 3.1

bulk move to assigned at the into of the triage step

I think this is not an issue anymore. I cannot reproduce it.

For Tables, Matrices, and Graphs: both the Save button in the workspaces window and the File->Save->Nexus action are disabled. The Save action is enabled only when you a workspace selected, and it applies to the workspace. Recent changes to this have been made in #1109, and possibly other tickets.

Another related (or duplicated) ticket: #8287

The option in File > Save is still there for me, both clicking that and using Ctrl-S allow me to try and save a matrix and always gives an exception.

Tested on the latest master.

I see, it still happens if you start from an empty environment. Once you have loaded a workspace at least and selected/deselected workspaces the problem seems to go away.

This also applies to all the other objects that you can create with New->, like note, 3D surface plot, etc.

So the issue would become something like this:

• Starting from an empty environment, if you create a table/matrix/graph/note, etc. the Save->Nexus action is active and you'll get an exception/crash if you try to use it for such objects.

prevent Save Nexus from being used on qti entities re #8318

I also updated "save project as" so that it is disabled at the beginning and becomes enabled as soon as the project is modified/something is done, or a project is loaded. This was for consistency with "save project" which is disabled at the beginning when you start in an empty environment.

Related to this, there are details in the behavior of the project save actions that I don't understand well, or they may not be well adjusted. For example, Save->Project is disabled if the project hasn't been modified since the last save. But if you double-click on the project (project explorer) it is somehow marked as modified and Save->Project is enabled.

Anyway, I think this exception/crash is now sorted out. To test:

• check that you don't get the crash, with empty and non-empty environments.

Seems that a checkbuild is needed:

ERROR: Branch 'feature/8318_qtiplot_entities_save_to_nexus_causes_exception_and_should_not_be_possible' has not been fully merged to develop, meaning it is not possible to know whether the code is valid on all environments.

[Federico M Pouzols]

Oops, it should work now...

[Raquel Alvarez Banos]

Merge remote-tracking branch 'origin/feature/8318_qtiplot_entities_save_to_nexus_causes_exception_and_should_not_be_possible'
