Allow graphical connection to array of connectors in omedit

[roeldeconinck@…]

I want to connect a realoutput to the first element in an array of realoutputs. This does not work because the connection triggers a translation, but off course, the translation fails cause I could not yet specify to which element in the array I wish to connect. I can make the connection textually, and the model checks fine. But then I have no graphical line between both connectors.

This issue is very similar to another bug I reported: it is extremely annoying that OMEdit checks/translates the model for every graphical connection I try to make. During WIP, the model is often not translatable.

Before the translation is triggered you should get a dialog window which asks you about the array index you want to connect to. If this is not happening then I need a sample model to test.

The translation is used to check the invalid connections but perhaps we can remove this then user is responsible to delete the invalid connections later on.

There are two conflicting issues here:

1. OMEdit needs to find out information about the model to be able to do connections, etc.
2. Model is a draft state (it might not even parse)

Truth is that in some cases we do instantiation (flattening) when we should not do that.
We should investigate the entire graphical API and see where we do instantiation and if it could be avoided.

I did not get that dialog window. Maybe it is indeed because the flattening happens before the dialog window has the chance to pop up?

With this minimalistic model, I can't graphically connect u to y[1]:

model testarray

Modelica.Blocks.Interfaces.RealOutput[2] y annotation(Placement(visible = true, transformation(origin = {103.59,7.17949}, extent = {{-10,-10},{10,10}}, rotation = 0), iconTransformation(origin = {103.59,7.17949}, extent = {{-10,-10},{10,10}}, rotation = 0)));
Modelica.Blocks.Interfaces.RealInput u annotation(Placement(visible = true, transformation(origin = {-96.7521,4.10256}, extent = {{-10,-10},{10,10}}, rotation = 0), iconTransformation(origin = {-96.7521,4.10256}, extent = {{-10,-10},{10,10}}, rotation = 0)));
annotation(Icon(coordinateSystem(extent = {{-100,-100},{100,100}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2,2})), Diagram(coordinateSystem(extent = {{-100,-100},{100,100}}, preserveAspectRatio = true, initialScale = 0.1, grid = {2,2})));

end testarray;

Thanks for the test model. It is now fixed in r18047.
