I don't understand your problem.
Is your question "You cannot connect a component to itself" if yes then it is not allowed.
Or your question is "You cannot connect two objects" if yes then post a use case to reproduce the issue.

Adeel.

yes I am meaning I can not connect two objects.
the GUI gives me the error message !
Well I can reproduce the issue at anytime even with 2 components example

I can't reproduce it on my Windows machine.

Adeel.

I can't even reproduce it on my virtual box Linux (ubtunu 12.04).

Are you clicking twice to start the connection?

Adeel.

thank you adeas,
is this a new feature ?
or I am just too tired to figure it ?
it works fine with a double click at the start ! so how come it works sometimes with a simple click ? maybe because it counts two successive attempts as a double click who knows !
anyway thank for your help                                                                                                                                                                                                                                                                        

Wait a second. There is something wrong. I need to test whats going on. There is something wrong with events.
When you double click you should get the error "You cannot connect a component to itself" because a single click will start making the connection.

Adeel.

ok,
so seems like something is reversed ?
actually double click works without a fault !
here is a gif capture of the error if it may help.

Hi, I think r23774 (https://trac.openmodelica.org/OpenModel … et/23774/) should fix everything. Note that now the connection will start through click and drag.

Adeel.

thank you for your help and efficiency
there are other new bugs I will report then
