LabVIEW 2010 crashes when changing representation of TypeDef

Question

Hello NI,
I have to report a bug
which causes LV 2010 to crash with error in "datamgr.cpp", line 2720.
This crash is reproduceable.I use LabVIEw 2010, 32 bit on Windows 7.
To cause this crash you have to perform the
following steps (I attached a sample VI to reproduce these steps.):
Place a ring control on the FP, change
representation to I32
On the BD, create a property node “Strings
And Values[]”
The datatype of this property is Array of
Cluster with 2 Elems, “String” & “Value”, where “Value” is of type I32
Create a control of this property,
surprisingly the type of Value is “extended”
On the FP, select the cluster inside the
array, click “Customize Control…” from Edit- menu
In the Control- Editor change the DataType
of Value to I32, then exit the Control Editor without saving the control,
but replacing the original cluster
LabVIEW 2010 will crash with the error
message stated above
The problem is to change the
representation of the cluster element, where the cluster is part of a typedef. A
solution is to forbid to call the “Customize”- editor directly from the FP (not
nice) or to forbid to replace the orginal control, instead force the user to
save the altered control to a .ctl (nicer).
This shows a general problem with TypeDefs,
where the array of a not-typedefed cluster is typedefed. This was discussed
earlier with the cursor list of waveform graphs (couldn’t find it anymore, but
read it in this forum) where this problem also can occur. So this is an appeal
to National Instruments to change the TypeDef to the clusters and make arrays
of them.
And, after all, for me it is
unexpected behaviour that a constant / control / indicator, created from a
property (or any terminal / node I can find on the BD) has another datatype
than the original terminal or node.

Answer 1

Hi All,
I am also facing the same bug from the long time which causes loss of data unexpected.Please solve this bug and tell me any way to solve this.I am using Control Type Def in my project.
Thanks
