AttributeParser is already initialized; cannot add patterns after initialization.

Error message

AttributeParser is already initialized; cannot add patterns after initialization.

Parameters

None

Error explanation

This error occurs when you attempt to register a new attribute pattern (IAttributeParser.registerPattern) after the attribute parser has already been initialized. Initialization happens automatically the first time an attribute is parsed (IAttributeParser.parse). Once initialized, the parser's patterns are fixed and cannot be changed.

Common causes

• Trying to register attribute patterns dynamically after the application has started compiling templates.

• Calling IAttributeParser.registerPattern in response to an event or user action after initial template compilation.

How to fix

• Ensure all attribute patterns are registered before any template compilation begins. The best place for this is typically during application startup or configuration.

• Register patterns via the @attributePattern decorator or by providing them to the container configuration, rather than calling registerPattern manually after initialization.

Debugging tips

• Check the stack trace to identify where the late registration attempt is happening.

• Verify the order of operations during application startup to ensure patterns are registered before parsing/compilation starts.
