After updating the Arm CMSIS Solution extension to version 1.64.x, the Software Components (RTE) view became partially broken.

[DrGebb]

OS and Version: Windows 10
VS Code Version: 1.107.1
Extension Version: Arm CMSIS Solution v1.64.0 / v1.64.1
Target Device: STM32F401RCTx
Other extensions: ARM Keil Studio Pack (Keil v6 stack).

Description:
After updating the Arm CMSIS Solution extension to version 1.64.x, the Software Components (RTE) view became partially broken. There are two main issues:
Identifier Mismatch: The extension adds components to the *.cproject.yml using shorthand identifiers (e.g., CMSIS:RTOS2:Keil RTX5&Source), but the bundled csolution (v2.12.0) fails to resolve them, throwing a no component was found error. It appears the backend now strictly requires the vendor prefix (e.g., ARM::CMSIS...), which the UI fails to provide.
UI/YAML Desync: When checking a component in the Software Components view, the entry is correctly added to the *.cproject.yml file. However, unchecking the component does not remove the entry from the YAML file. This leads to "zombie" dependencies that must be manually deleted from the code.

To Reproduce
Steps to reproduce the behavior:
Create or open a project for STM32F401RCTx using Arm CMSIS Solution v1.64.1.
Open the Software Components (RTE) view.
Select any component (e.g., CMSIS:RTOS2:Keil RTX5).
Observe the output log: 🟥 RPC: ConvertSolution failed with error csolution error: no component was found with identifier 'CMSIS:RTOS2:Keil RTX5&Source'.
Try to uncheck the same component in the RTE view.
Check the *.cproject.yml file -> The component entry remains in the file despite being unchecked in the UI.

Expected behavior
The extension should generate component identifiers that are compatible with the bundled csolution version (including vendor prefixes if necessary).
The UI should maintain two-way synchronization with the YAML file: unchecking a box in RTE should immediately remove the corresponding line from the *.cproject.yml.
ConvertSolution should complete successfully for standard CMSIS components that worked in v1.62.1.

Additional context
The project worked perfectly in version 1.62.1. The issue started immediately after the auto-update to v1.64.0/1.64.1. Downgrading the extension back to v1.62.1 restores correct RTE behavior and successful solution conversion.

I found the same problem when I created a new project for the STM32F756. As soon as I added CMSIS:RTOS2:Keil RTX5&Source, the problem occurred. Only the heading is visible in the CMSIS view. The files, e.g., from the RTOS, are not visible. Then the errors described above occur.

Perhaps a problem with the & character or the space in the component name.

The issue is due to the fact that the pack is not added automatically anymore.

The component "CMSIS:RTOS2:Keil RTX5&Source" comes from the pack "ARM::CMSIS-RTX@5.9.0", however this pack is no longer automatically added to the *.cproject.yml file.

Workaround: add manually the pack to the *.cproject.yml file

 packs:
      :
    - pack: ARM::CMSIS-RTX@^5.9.0

These errors are somewhat duplicated an misleading.

csolution error: no component was found with identifier 'CMSIS:RTOS2:Keil RTX5&Source'
csolution error: unresolved components:
CMSIS:RTOS2:Keil RTX5&Source
csolution warning: DataTest.cproject.yml - dependency validation for context 'DataTest.DebugRec+AVH-SSE-300' failed:
MISSING CMSIS:RTOS2:Keil RTX5

Better would be just one error

csolution error: component 'CMSIS:RTOS2:Keil RTX5&Source' not found in included packs.

Thanks for the information. I tested it. It seems that cproject no longer creates a pack area. You have to add the pack entry for each component you want to select.
