LMDDock 2021 problem

Ravil

Hi.

With version 2021 I can not run project with LMDDock library. This is message when I try to run your demo project (my own projects not working too): 

---------------------------

Debugger Exception Notification

---------------------------

Project pDockingDemo.exe raised exception class EReadError with message 'Property ParentBackground does not exist'.

This is strange. I just checked using Delphi XE2 and Delphi 10.4.2 - no problems with our demo.

Which IDE version you use?

What are required steps to reproduce the issue?

Ravil

Hi.

I use Delphi 10.4.2: https://monosnap.com/file/IucdHaQhYfwZEU6stWGoxuEno2kfIO

May be something wrong with your library paths or previous installations. Because, ParentBackground property is an existing published property of TLMDDockPanel class (LMDDckSite.pas, line 379).

Ravil

Hi

This property is not exists (attached file).

Attached file.

This is old 2020 file.

Ravil

Hi.

The date of this file is today - I just install 2021 version.

Refards, ravil.

Please specify the name of the installer you used. 

We just tested setupel21src.exe (ElPack 2021 source installer) and the file you have attached is definitely not included (your file is from 2020 release).

Ravil

Hi.

1. Uninstall previous version.

2. Delete directory with 2020.

3. Install 2 files: setupel21d27.exe, setupel21src.exe

4. Result is the same - old file LMDDckSite.pas

Ravil

Hi.

But now I can compile the project. Very strange.

Rafael Maricca (LMD)

Sorry - no way to reproduce this. The LMDDckSite.pas file from 2020 file must be originated from somewhere else.

Here is the source folder after installation with setupel21src.exe:

In the install.log file in your main folder you can search for LMDDockSite.pas file including time stamp etc. and the exact destination location, it should look like this:

So make sure that your LMDDckSite.pas is time stamped with 06-Apr-2021 and time 21:00:00.

>>2. Delete directory with 2020.<<

Delete directory might not be sufficient. If you installed source code yourself, the runtime/designtime packages of 2020 release may be still around in your default package folders.

>>3. Install 2 files: setupel21d27.exe, setupel21src.exe<<

You are installing a compiled version as well? Are you compiling the source files yourself at all? What is the purpose?
