MARKLESS_ATTRIBUTE_OBJECT_VALUE

Lowercase on* attributes are plain HTML attributes: a Markless compiler warning.

Warning from the compiler, while it builds your .tsrx files.

What happened

Markless prints the message, the reason, and a suggestion:

MARKLESS_ATTRIBUTE_OBJECT_VALUE: `<attributeName>={<valueSource>}` is a plain attribute, not a Markless event. It would serialize the function source into HTML.<eventText>
Attribute bindings serialize to plain text in HTML and DOM updates; only graph cells keep structured values across resume.
Use the event prop casing, for example `<eventSuggestion>={...}`, or serialize a string deliberately.

Words in angle brackets change from case to case.

How to fix it

Start with the suggestion in the message above.

If you accept the warning on purpose, put this comment on the line above it:

// markless-allow MARKLESS_ATTRIBUTE_OBJECT_VALUE: the reason you accept it
