path access (.)
FEEL language construct
context.entryName
The dot operator reads an entry out of a context and chains for nested structures. Reading an entry that does not exist yields null rather than an error, which is why a typo in a path silently collapses a decision to null instead of failing loudly.
Syntax elements
| Element | Type | Description |
