LinkedActionFID

property LinkedActionFID: TGuid read write;

Example​

procedure ScriptEvent(var Value: Variant);
var
  ChildFID: TGuid;
begin
  { LinkedActionFID is not runtime-bound in the current product. }
  ChildFID := GetActionFID('Child Flow');
  Value := GUIDToStringNoBraces(ChildFID);
end;

Usage​

Do not read or assign LinkedActionFID in current Velox scripts because the property cannot be bound when the script executable loads.

For explicit nested execution, resolve the target with GetActionFID and pass that identifier to ExecuteFlow. Product-configured linked actions remain a separate flow configuration feature.

Behaviour

Do not read or write Action.LinkedActionFID in the current Velox version. A script that references this property is expected to fail while loading because the property is unavailable during execution.

Use GetActionFID to resolve an intended target and pass that identifier directly to ExecuteFlow when explicit nested execution is required. Product-configured linked actions remain a separate flow configuration feature.

Errors

A script that references this property can compile against the class declaration but fail when Velox binds the compiled script to runtime class helpers. No value-level try/except can make an unbound property reliable.

Additional Technical Info​

LinkedActionFID is declared to the script compiler as the read/write TGuid identifier used by Velox linked-flow configuration, but the current runtime import does not bind that property name correctly.

Declared value

The native field defaults to the empty GUID and is used by the product's configured linked-action loading/saving behaviour.

Implementation defect

Compile-time registration declares LinkedActionFID. The matching runtime getter and setter exist, but runtime registration mistakenly registers them under the name Actions. A later registration adds the real indexed Actions getter under that same name, and the PascalScript importer resolves the newest matching class item first.

Consequently, Actions[Index] has its intended current getter, while no runtime helper is registered under LinkedActionFID.

Edge cases and quirks

  • This is a product registration defect, not an invalid GUID value or permissions failure.
  • The generated Code Library page remains accurate as a declaration inventory but must carry this runtime warning until the import is fixed.
  • Correcting _Index.json or the Markdown cannot repair runtime binding; the product import name must change.
  • Do not use the accidental Actions registration as a GUID back door; the real indexed registration shadows it.
