Export-import problems with a use case

[johnafitch]

Because of the UI limitations that I experienced per Discussion #975, I attempted to download/export the textual model of my example, fix it in a text editor and import it into a new package. The combined exported (first package), then imported (2nd package) code was:

package 'Direct Input - Flat structure' {
use case 'useCase-Transport1' {
action start {
action forkNode1;
action driverGetInVehicle;
action passenger1GetInVehicle;
first forkNode1 then driverGetInVehicle;
first forkNode1 then passenger1GetInVehicle;
action joinNode1;
action '^done';
action driverGetOutOfVehicle;
action passenger1GetOutOfVehicle;
action driveVehicleToDestination;
action providePower;
first driverGetInVehicle then joinNode1;
first passenger1GetInVehicle then joinNode1;
first forkNode2 then driveVehicleToDestination;
first forkNode2 then providePower;
action forkNode3;
first driveVehicleToDestination then forkNode3;
first providePower then forkNode3;
first forkNode3 then driverGetOutOfVehicle;
first forkNode3 then passenger1GetOutOfVehicle;
first driverGetOutOfVehicle then '^done';
first passenger1GetOutOfVehicle then '^done';
action ignitionCmd {
inout payload;
in receiver = ;
}
first joinNode1 then ignitionCmd;
action forkNode2;
first ignitionCmd then forkNode2;
}
}
}

Edited, then imported:
package 'Import actions under UC' {
use case 'useCase-Transport1b';
action start;
action forkNode1;
action driverGetInVehicle;
action passenger1GetInVehicle;
first forkNode1 then driverGetInVehicle;
first forkNode1 then passenger1GetInVehicle;
action joinNode1;
action '^done';
action driverGetOutOfVehicle;
action passenger1GetOutOfVehicle;
action driveVehicleToDestination;
action providePower;
first driverGetInVehicle then joinNode1;
first passenger1GetInVehicle then joinNode1;
first forkNode2 then driveVehicleToDestination;
first forkNode2 then providePower;
action forkNode3;
first driveVehicleToDestination then forkNode3;
first providePower then forkNode3;
first forkNode3 then driverGetOutOfVehicle;
first forkNode3 then passenger1GetOutOfVehicle;
first driverGetOutOfVehicle then;
first passenger1GetOutOfVehicle then;
action ignitionCmd {
inout payload;
in receiver = ;
}
first joinNode1 then ignitionCmd;
action forkNode2;
first ignitionCmd then forkNode2;
}

Several anomalies occurred in this process.

1. The General View of the imported model appears to have lost all relationships between the actions
2. All special action types (forks, joins, accept actions) appear as simple actions
3. The use case parent shows up as a sibling of all the actions that it was intended to contain.
   Some of this may be cockpit and coding errors on my part. If so, please advise.

The import from textual SysMLv2 and export to textual SysMLv2 with SysON are currently under development and we still have some unhandled concepts/relations in both cases.
We are working on it to handle all the missing cases and provide the most accurate versions of these modules.
