I just create a simple project, a form with a button, auto complete works.

After I add a TcxButton (or others DX component), now auto complete is not work.

Hello,

Thank you for informing us about this problem. I've replicated it on my side but only with the Sydney IDE - other IDEs work correctly.
It seems the issue is caused by the fact that Embarcadero introduced a new feature in the Sydney IDE that may work with problems:
New in Delphi 10.4: Redesigned Code Insight
I recommend you contact Embarcadero's Quality Center about this.

In turn, we will also study this problem at the level of our controls.
We will get back to you once we have any results or need additional information.

Hello,

We've examined the issue. It occurs because Embarcadero's new server broke the correct work of code autocomplete in the IDE (see the attached screenshot with this add-on).

To fix this issue, use the following approach:

Choose the Tools > Options > User Interface > Editor (Options) > Source option in the IDE's main menu;
Click the Code Insight option;
Switch the Code Insight Manager from Delphi ("Language Server Protocol") to Delphi ("Classic Code Insight").
After that, the code autocomplete will work as expected.

Hi Mikhail,

i hope this is only the workaround and not the final answer.

The LSP is one of the most important features of Delphi 10.4.

So I hope you will get in contact with Embarcadero to get this fixed. On Delphi or on DevExpress site.

Regards
Jens

Is this fixed? according to Embarcadero it is closed as they cannot reproduce it

Hello,

I believe Embarcedero's developers tested this behavior with the latest IDE (10.4.1).
The current version of our controls (v20.1.4) does not support it. However, we are planning to release VCL v20.1.5 this week. This version should support the 10.4.1 IDE, and you will be able to test this functionality.

Besides, you can ask Embarcadero about this issue in this thread: https://quality.embarcadero.com/browse/RSP-29674.

I need to be very clear on this…

Can Dev Express confirm that Language Server Protocol Code Insight in Delphi 10.4.1 works correctly with Dev Express VCL 20.1.5?

Hello,

LSP is Embarcadero's feature and we cannot guarantee that it works correctly in all cases. We tested it on our side with our controls and it seems to work without problems.
However, I believe if you face any difficulties or problems with its operation, it is necessary to contact their Support Department about the issue or LSP nuances.

Hi Mikhail,

this is for me a strange definition.

You're software is designed for the use with the IDE. If there is a problem between the IDE and the way you're software is build, I would think that it's to simple to say we are out of race. Only Embarcardero has to look.

If there is a problem how the software is working with Windows you are also not saying, that's a microsoft problem. Normally you would also start - if it's a critical issue - together with Microsoft to fix the problem or in the minimum to find a workaround.

And this problem is not a smaller issue, for me this sounds like a critical issue.

Only my personal thinking :-)

Hello Jens,

I understand your point of view. You are absolutely right - we are resolving issues together with Embarcadero.

LSP is a new IDE feature, and we cannot guarantee that it will work without issues in all cases. We always try to resolve issues at the level of our controls.
However, we cannot alter inner IDE features (e.g, LSP mechanisms). We write our code according to the rules. If these rules do not work, we create a ticket in Embarcadero's Quality Center and they fix it.
This is exactly the case discussed in the current ticket - the issue is fixed at the IDE level since it was not caused by our source code.

If Embarcadero is unable to fix a certain problem, we are trying to find a workaround at our level. However, in this case, it is not necessary to do so.

I fully agree with Mikhail!

The new Delphi LSP still has many open issues. These must be solved by Embarcadero and DevExpress should not be held responsible for this.

LSP problems with large projects: https://quality.embarcadero.com/browse/RSP-30627
LSP problems with Error Insight: https://quality.embarcadero.com/browse/RSP-30667
(may one have a look into the video in RSP-30627 to see the behavior of DelphiLSP)

… and many other open LSP issues.

I'm totally with both of you.

Embarcardero has to fix this.

I was only surprised a little bit, because it sounds in the original comment like, as DevExpress will not look into this.

But Mikhail explained it in exactly that way like I have expected it.

From DelphiLSP can be seen on Task Manager, 3 threads.

When I killed the 2 threads with bigger memory consumptions, it restarts automatically and auto complete now run.

This not good trick, but at less can solve.
