v8.0.0 build crashes upon DBC decoding data

[MatinF]

I tried v8.0.0 just now to DBC decode an OBD2 file (attached) - it results in an unending loop of the decoded file being created, forcing a manual shutdown of asammdf. You can try to see if it's repeated on your end with the attached

Hi Daniel, this build seems to fail when I open the GUI:

Hi Daniel, just wanted to check if you've had the chance to review this further?

Just FYI I tried also the latest dev build 8.0.2, but here I get below issue when trying to open it on Windows 10:

please try this versionhttps://github.com/danielhrisca/asammdf/actions/runs/11889185054

Hi Daniel, this seems to resolve the crashing and allows for DBC decoding data again - so that's much better!

Minor observations:

1. It seems visually that there is an issue with the margins on various elements - as if the margin width has been set to 0. While not critical, I think this might be a bug as it's not how it looks in prior releases:

2. From what I can tell, LIN bus decoding with DBC files does not work currently. When I try to decode below samples, it fails. I think this has been a problem since back in 7.5.0 and maybe earlier releases as well.

3. In the raw CAN bus trace, enabling 'Time as date' seems to have no effect

Hello Martin, have a try with this build https://github.com/danielhrisca/asammdf/actions/runs/11893707166

All the layouts have been setup with 1px margins to reduce wasted screen space

[MatinF]

Thanks Daniel, this is great - solved the previous issues!

One other issue we've had reports on from users is inconsistency in terms of the localized PC time across the 'Raw CAN bus trace' and the 'decoded' physical values plots. See below example:

As evident, the raw CAN bus trace starts at 09:43 (+02:00)

The decoded physical plot seems to start at 08:43 (+01:00), while the left-side timestamp shows 07:43 (+00:00).

I realize that the times are in principle all correct because of the explicit time zone factor at the end of them. But I guess the intuitive solution from my view would be to have all of them show the same localized time, with the correct one being the +02:00 in this particular log file example case, i.e. what the raw CAN bus trace displays. But let me know if there is a reason for the differences that I am missing?

[MatinF]

Hi Daniel, wanted to check if you've had the chance to implement a solution for the time zone issue I mentioned? We'd love to get out asammdf GUI hosted version updated with some of these fixes.

Hello Martin, please try the development branch code

Latest build seems to give an error when opening:
