canNavigate (sbo.p)

Acts as a pass-through for the same function in some contained SDO, passing the result back to the caller to which the SDO is mapped. An SDO can navigate if it has no children or its children have no commits pending. Children with uncommitted updates prevent navigation by the parent.

Parameters: None

Returns: LOGICAL

Notes: This routine publishes isUpdatePending because that includes rowObjectState in the check. Navigation objects receive updateState from the objects they navigate and must perform this check in the source of any updateComplete message. The updateComplete message can come from a branch of a data-link tree; publishing isUpdatePending checks the whole tree.
