Hi, can take up this issue?

[github-actions]

As a general advice for newcomers: check out Contributing for a start. Also, guidelines for setting up a local workspace is worth having a look at.

Feel free to ask here at GitHub, if you have any issue related questions. If you have questions about how to setup your workspace use JabRef's Gitter chat. Try to open a (draft) pull-request early on, so that people can see you are working on the issue and so that they can see the direction the pull request is heading towards. This way, you will likely receive valuable feedback.

Steps to reproduce the behaviour

Have a pdf file linked to an entry
Click entry

Hi I'm new to Jabref and I'm facing issues reproducing this error , can you please give me bit more detailed explanation what is an entry and what kind of pdf file i should use to reproduce this error?

[koppor]

An entry is an entry in a .bib file. Example bib file: https://github.com/JabRef/jabref/blob/main/src/test/resources/testbib/Chocolate.bib

Drag and drop a PDF into a line in the main table. Attach the PDF. Then, you can open the PDF in JabRef.

• There should also be a tooltip showing what "Locked" means

Is there any tutorial available which guides how to create a .bib file or use an existing file in our local system?

[ThiloteE]

@Anirudhxx If you open JabRef, an empty library will be created. If you add entries to that library, it will automatically be saved as .bib file.

I don't know your previous experiences. Did you use an application working with files? Like Microsoft Word or Notepad++?

Maybe, the wording "library" is confusing for you? A library is a .bib file.

If you had installed JabRef and checked out JabRef, you could navigate to the JabRef folder, go to src/test/resources/testbib sub directory and double click on Chocolate.bib. Tests on Windows only.

documentViewerView.setLiveMode(false);
i think here we're trying to directly set a bound value of togglebutton modeLive is causing the issue. But when i tried fixing it
boolean currentLiveModeValue = viewModel.liveModeProperty().get(); // Toggle the value boolean newLiveModeValue = !currentLiveModeValue; // Update the view model with the toggled value viewModel.setLiveMode(newLiveModeValue);
it's still showing the same error, do you have any suggestions?

[Siedlerchr]

The error message is clear. You cannot set a value that is set using Binding. Maybe you should read about javafx. bindings first https://www.informit.com/articles/article.aspx?p=2251210&seqNum=4

Hello, I'm testing the software trying to understand the reason for the bug, but I'm struggling to fully comprehend the function of the 'live' and 'locked' buttons. What would be their purpose? Additionally, I've noticed that when I press the 'live' button, it then moves to 'locked' (thus allowing me to enter 'locked' mode and avoiding the bug). However, I would like to understand if this is an additional issue to be fixed or if it's intended behavior. Thank you for your responses, and I apologize for any potentially silly questions as I'm new to this software.

@SimoneSantin Do you know about Ctrl+Shift+F in IntelliJ? I searched for "Locked".

I found something interesting in DocumentViewer.fxml:

<Tooltip text="%Show this document until unlocked."/>

The other one is

<Tooltip text="%Show the document of the currently selected entry."/>

The intention is to be mutually exclusive:

Either the document viewer updates the document on change of a BibEntry (modeLive) or it keeps the current document (modeLocked). Therefore, there is a bi-directional binding of modeLock and modeLive.

HTH!

@SimoneSantin I saw that we both overlooked that the issue was already assigned. Thus, a fix was meanwhile implemented and merged into main. Please choose another issue.
