Hi all,
I think it is an issue that could be fixed easily.

let's say we build a simple pipe:

Modelica.Fluid.Pipes.DynamicPipe p11(length = 10., diameter = 0.05)

then i modify my code directly in the text editor in the text view link my code is then the following

  Modelica.Fluid.Pipes.DynamicPipe p11(length = 10., diameter = 0.05, height_ab = 0, redeclare package Medium = Modelica.Media.Water.StandardWater constrainedby Modelica.Media.Interfaces.PartialMedium)

now let's go bat the diagram view option and let's say i want to increase the nNodes from 1 to 5. You open the menue while clicking on the p11 object and modify the nNodes value click OK and check the code. nNodes will not appear this means the link between the diagram view and the text view is lost.

This issue concerns all parameters and all the objects in modelica.

Once you add something in the text vew you loos the link with diagram GUI.

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

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.

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                                                                                                                                                                                                                                                                        

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

Dear all,

I am using OM with the following version 1.9.2+dev (r23710), on Ubuntu (Linux jugurtha 3.16.0-031600-generic #201408031935 SMP Sun Aug 3 23:36:11 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux).

Everything was running fine till last updates (I can not exactly identify the update).

Now I am experimenting annoying problem on the GUI.

It takes me nearly 5 to 7 attempts to make a link between two objects let's say between two pipes ! 

I tried to rest my environment by creating a new .openmodelica/ path or even reinstall OM. The problem is still present.

Anyone one else is facing the same problem as me ?

How can I fix this ?
Thank you all !
