Symbols Browser - Go to definition (project file or server definition)

[GreatScott000]

More often than not I get this error when trying to go to a definition in Base App. I double click the object, select my launch configuration and then the error appears. Sometimes it works but most of the time it doesn't. This has been happening for a while.

What am I doing wrong? What more information can I provide to assist in investigating the issue?

AZ AL Dev Tools version 3.0.16

Hi.

Is it broken for all object types? Do you see any errors if you run "Open AZ AL Dev Tools Log File"? To which version of BC are you deploying your code? Is it BC18 or something older? Are you using Microsoft AL Extension from VS Code marketplace or from VSIX file? Do you have just 1 base app file in your .alpackages folder?

You should not see this error message at all. It is old "go to definition" functionality that I've decided to leave here just in case the new, faster logic breaks.

Sorry, I have been on annual leave. Let me review this and I will get back to you.

I went to do some testing today and it seems to be working at the moment. Yesterday it was not. I will continue to monitor.

It is not working today on my laptop. I have tried pages, reports, codeunits and tables

It worked fine all day yesterday on my PC. But I can't check because I had to come into the office today.

Here is the log file.

Hmm, okay so I was getting this message

cannot open al-preview://allang/BC%20Extension/Table/3/Payment%20Terms.dal. Detail: Unable to resolve text model content for resource al-preview://allang/BC%20Extension/Table/3/Payment%20Terms.dal

and then redownloaded symbols and it now works.

The first issue this morning was maybe related to my container (Docker Desktop) was not fully started. Can you determine if it is a communication error and include that in the messaging?

Thank you for checki it. I've modified a bit code of the extension to handle these NullReference execeptions. They look like a problems with opening *.app files.

Unfortunately I cannot do much with your second problem. I am just building the path and then I call standard "open document" functionality. "al-preview" protocol is implemented by Microsoft AL extension and it connects to the server, downloads source code and shows the file.

Getting this error today trying to go to definition. "Pag.al" is my currently open object file. Why is being accessed and why it is a problem?

Hi

I'll check it. My extension monitors file changes to collect symbol information in the current project, but it should not access file when you run go to definition.

Hi

I've released a new version of the extension, it contains a fix preventing your file read/locks issue.
