[LVGL] Code generation error in screens.c when assigning variable to Roller.

[tobinieil04]

Describe the bug A code generation bug occurs in EEZ Studio when using LVGL v9.x. The bug appears when trying to assign a variable to the options property of an lvgl_roller object. The issue manifests in the generated screens.c file within the src/ui directory after building the project. Despite updating EEZ Studio to version 16.1, the bug persists.*

To Reproduce Steps to reproduce the behavior:

1. Create new LVGL project in EEZ Studio 16.1 (latest).
2. Add Roller object to main page.
3. Create a global string variable and assign to roller options in properties.
4. Hit build.
5. Check generated screens.c file in output src/ui directory.

Expected behavior The generated screens.c file should correctly reflect the assignment of the variable to the options property of the lvgl_roller object, with no errors.

Actual Behavior:

• The variable assignment to the options property of the lvgl_roller object is incorrectly handled in the generated screens.c file, resulting in incorrect code generation.

• This issue appears exclusively in the screens.c file after building the project.
