Duplicate of read only model is also read only (but shouldn't)

[Christian Kral <dr.christian.kral@…>]

If I load any system library in OpenModelica, then the library is marked as read only. If I make a copy of any model to be treated as a new separate model, then the model is also marked as read only -- which does not make sense.

Reproducible example:

• Open Modelica Standard library
• Double click on Modelica.Blocks.Examples.Filter
• Right click on Filter and select Duplicate

  Name: Filter
  Path: (blank)
  

• Change Modelica code in duplicated model
• A warning appears: Warning: You are changing a read-only class.

If I unload the model an re-open it, the read only warning is not shown any more...

It's not critical, but it would be nice to have it fixed in 1.14.0

I am unable to reproduce this issue.
It works as expected for me.

[Francesco Casella]

I am also unable to reproduce the issue with the latest nightly build. @christian, what version of OMEdit are you using?

Replying to casella:

I am also unable to reproduce the issue with the latest nightly build. @christian, what version of OMEdit are you using?

I am using

OMEdit 1.14.0~dev-45-g9f3d0f7
Connected to OpenModelica 1.14.0~dev-285-g270177b
Connected to OMSimulator unknown-linux

on Linux Mint 19.1 64bit XFCE.

[Christian Kral <dr.christian.kral@…>]

I actually also tested this issue under Linux Mint 18.3 64bit XFCE. It does not work either on this version of Linux Mint.

Maybe it' a Linux thing.

@Andrea.Bartolini, can you try this please?

[Andrea.bartolini]

I confirm the wrong behavior reported by Christian.
Moreover, if you modify the model (for example adding a parameter) and save it, the modification is saved, in spite of the shown warning.

OMEdit 1.14.0~dev-45-g9f3d0f7
Connected to OpenModelica 1.14.0~dev-285-g270177b
Connected to OMSimulator unknown-linux

Sysop: Linux Ubuntu 16.04

[Francesco Casella]

Then, the problem is probably caused by the way Linux handles file properties, which is different from Windows?

[Adeel Asghar]

I can't even reproduce it on Linux.
@Christian and @Andrea.Bartolini can you post the output of the attached script?

[Andrea.bartolini]

Here the output of the script on my PC:

andrea@andrea-hp-pavilion-notebook:~/Downloads$ omc script.mos
true
""
true
""
("model","Demonstrates the Continuous.Filter block with various options",false,false,false,"<interactive>",true,169,3,250,13,{},false,false,"","",false,"")
""

[Adeel Asghar]

Martin any idea why do we get true for readonly attribute?

[Adeel Asghar]

Ahh maybe for you the Modelica.Blocks.Examples.Filter is readonly and then the SOURCEINFO is copied as it is.

[Adeel Asghar]

Hopefully 91743ce/OMCompiler fixes this issue.

[Christian Kral <dr.christian.kral@…>]

I tested version

OMEdit 1.14.0~dev-47-g29420dd
Connected to OpenModelica 1.14.0~dev-323-g220cd16
Connected to OMSimulator unknown-linux

and the issue does not appear any more. So it seems to be fixed from my point of view.

Please reopen if the issue pops up again.
