SyntaxError in Plus Viewer When DocumentType is not Tagged

[austinmatherne-wk]

If the DocumentType is not tagged, the instance section body ID will include parentheses (e.g., #instance-body-sectionDoc-(Source)), which results in an invalid CSS selector runtime exception. This issue prevents users from progressing beyond the Processing Inline Facts... loading screen unless the ID is properly escaped.

Example:
#instance-body-sectionDoc-(Source) div.accordion-body

You can reproduce this issue with the provided filing_documents.zip. However, any report missing the DocumentType tag will cause the same problem.

@austinmatherne-wk i'm unable to replicate your issue. Steps take to try to reproduce below.

1. Download attached zip
2. Open Arelle and enable EDGAR Renderer plugin
3. Under tools -> validation -> select disclosure system... -> select US SEC (EDGAR Filing Manual, Pragmatic)
4. Open the zip file and select austin-20250115.htm file.
5. When the FilingSummary page opens up I click on the yellow button (does not have any text because documentType is missing).
6. Inline viewer loads ok and I can see 1 fact in the facts sidebar.

Hi Freddy,

Thanks for investigating.

It looks like there's one additional requirement to reproduce the issue. An SEC disclosure system must not be selected.

• With an SEC disclosure system the yellow button text is blank (and the corresponding CSS selector does not include the invalid (Source) string).
• Without an SEC disclosure system the yellow button text is (Source) (and it's included in the CSS selector).
