Check if it opens on master, if yes then likely this has been fixed in core, will test after upgrading if not then open an issue for opensim-core. Thanks @tkuchida

[tkuchida]

The following works on master:

auto Model = model("bouncing_block.osim");
model.finalizeFromProperties(); //throws exception if this line is omitted
model.printSubcomponentInfo();

[aymanhab]

The GUI workflow invokes initSystem (which implicitly calls finalizeFromProperties), the change to require the new call finalizeFromProperties was not in the alpha code base, so I'd expect the issue to go away with upgrading API. Would be great though to try opening other models from the GUI-alpha distribution using master so that any necessary fixes are incorporated into the API core beta. Thanks much @tkuchida for investigating 🥇

[tkuchida]

All models in opensimWin64Alpha01\opensim\models\*.osim /s load successfully in the API on master.

Test code

auto model = Model(filename);
model.finalizeFromProperties();
model.printSubcomponentInfo();

Awesome, excellent job @tkuchida 👍

[jenhicks]

Moved to "needs verifying" list for testing in the next GUI build

[aymanhab]

Trying to load the model now gives the error dialog

This obviously is the latest API Beta since Sockets mentioned in message didn't exist in previous versions
model in opensim-models/Models/BouncingBlock/bouncing_block.osim

Still unable to open bouncing_block.osim with opensim_devWin64_060217.zip (same dialog box as @aymanhab noted on Apr 3 post, above).

[tkuchida]

Tested again using opensim_win64_070517_2.zip on Windows 7. Error message is identical to what Ayman posted above (Apr 3). Contents of Messages window:

This obviously isn't a GUI issue until corresponding API issue is resolved

[jenhicks]

Issue moved to opensim-org/opensim-core #1856 via ZenHub
