APEXLang metadata:
.apex/apexlang.json contains:
{
"mmdVersion" : "26.1.0+3102"
}

Project structure:
I am opening the root folder of the exported APEXLang application, not only the pages folder.

Example structure:

aurora/
.apex/
apexlang.json
pages/
p00001-....apx
p00065-....apx

Problem description:
I exported an Oracle APEX application using Oracle SQL Developer Extension for VS Code.

After opening the exported APEXLang application folder in VS Code, the extension detects APEXLang correctly. When I open a page .apx file and edit the property:

cursorFocus: doNotFocusCursor

I delete only the value and leave the cursor after the colon:

cursorFocus: |

Then I press Ctrl + Space.

Issue 1 - Slow autocomplete:
With my normal VS Code extensions enabled, the autocomplete popup stays in "Loading..." for around 1 or 2 minutes before showing any suggestions.

Issue 2 - Incorrect suggestions:
If I start VS Code with extensions disabled using:

code --disable-extensions /home/vpacheco/Documents/apex/aurora/

then autocomplete opens quickly, but it still does not suggest valid values related to the cursorFocus property. Instead, it shows generic or unrelated suggestions.

Expected behavior:
When the cursor is after the property name and colon:

cursorFocus: |

and I press Ctrl + Space, APEXLang should suggest valid values for the cursorFocus property, such as:

doNotFocusCursor

Actual behavior:

• With normal extensions enabled, autocomplete takes around 1 or 2 minutes to show suggestions.
• With other extensions disabled, autocomplete is fast, but the suggestions are not specific to cursorFocus and do not show the expected valid value.

Additional information:
The Oracle SQL Developer extension version is 26.1.2.
The project root folder is opened correctly.
The .apex/apexlang.json file exists and contains mmdVersion 26.1.0+3102.
APEXLang is detected in the status bar.
The problem happens inside a .apx page file.

Command used for comparison:

code --disable-extensions /home/vpacheco/Documents/apex/aurora/

I am aware that the production of a snippet for a child component can be very slow (by which I mean more than a few seconds). I am working on a fix for this. I have not seen the kind of performance you are describing ever, especially for code completion of a property value following propertyName:. I will look into this, I guess amount of memory the jvm is allocated might be a factor. If you can give any further info, that would be helpful.

I don't think "other" extensions being enabled is relevant btw - when you use code --disable-extensions you are also disabling SQLDeveloper and so you have no APEXlang support. Any code completion is just text that vscode comes up with based on what it finds in the file, if any.
