This section contains reference information about possible block diagram syntax errors related to LabVIEW classes.

A class input to this tunnel or shift register does not originate at the Data Value Reference Read Element border node
Accessor VIs have different data types
Cannot have dynamic outputs without a dynamic input
Cannot use Call Parent Method node outside of a LabVIEW class
Child class overrides a property accessor VI in a bad location within the class
Class cannot be bundled or unbundled because the class private data is empty
Class input terminal is not marked as required
Class or error data is assigned to the wrong side of the connector pane
Class output terminal does not return the input class
Class type of input terminal does not match class type of output terminal
Constant value includes broken or missing LabVIEW class
Dynamic front panel terminal cannot be placed inside a structure
Illegal Property Node recursion
Incompatible property definition override
Invalid accessor VI connector pane
Neither bundle nor unbundle of this LabVIEW class is allowed on this VI
One of the class inputs to this Max and Min function does not originate at the Data Value Reference Read Element border node
One of the class inputs to this Select function does not originate at the Data Value Reference Read Element border node
One of the class inputs to this Select function does not originate at the dynamic control
One of the class terminals is static and the other class terminal is dynamic
One of the inputs to this Max & Min function does not originate at the dynamic input front panel terminal
One or more of the inputs to this tunnel or shift register does not originate at the dynamic input front panel terminal
One or more of the set of VIs that this dynamic dispatch subVI or property item may call are broken
Parent class does not define this method
Property is not readable
Property is not writable
Reentrant VI with dynamic input terminal must use 'Shared clone reentrant execution' option
Reference creation and deletion for this class is restricted
Refers to a broken LabVIEW class
Refers to a dynamic member VI
Refers to a missing LabVIEW class
Run-time type not propagated from dynamic input to dynamic output
The class object inside a reference cannot be exchanged with another class object
The overriding accessor VI has a different filename than the accessor VI in the parent class
The property definition adds readability or writability to an overridden property
The property definition folder contains a member that is not a VI
The property definition folder does not have a valid accessor VI
The property definition folder has a colon in its name
The property definition folder has a duplicate long name
The property definition folder has more than one read VI
The property definition folder has more than one write VI
The wired class does not support a method of this VI's name
This dynamic dispatch VI does not unconditionally invoke the Call Parent Method node
This function does not support LabVIEW classes
This VI cannot access the class constant
This VI cannot access the referenced item
This VI cannot access the referenced item in community scope
This VI cannot access the referenced item in private scope
This VI cannot access the referenced item in protected scope
This VI cannot connect to the referenced item in a locked library
This VI is not an accessor VI, but it overrides one
To More Specific Class must cast to the original data type of the Data Value Reference Read Element border node
To More Specific Class must cast to the original data type of the dynamic input front panel terminal or an ancestor type
Unexpected type on accessor VI class or error terminal
Wrong connector pane pattern for accessor VI
You cannot type cast between different data value reference types
