Unusual behaviour [Valentina with LIVECODE API, Converting BitSets to ArraySets]

Lastly, the error details when I crash/hang:

Looks like it is stemming from the Valentina module.

Following on from 1st e-mail, additional tests:

 

When I write:

 

   put VField_FindValue (fldCode, "E001") into tBitSetRef

   put VSet_Count(tBitSetRef) into tCount

   put tCount after field efDisplay

 

I will get 1 appearing (correct as only one record with code E001).

 

BUT when I write:

 

   put VField_FindValue (fldCode, "E001") into tBitSetRef

   put VArraySet_FromBitSet (tBitSetRef) into tArySetRef

   put VSet_Count(tArySetRef) into tCount

   put tCount after field efDisplay

 

I don't hang...but I don't get any output in field efDisplay as well???
Nothing happens!

 

I am trying to get comfortable with converting BitSets to ArraySets but
right now, I seem to be doing something wrong.

Btw, I am using Valentina 4.8.1 with Livecode 4.6.4

Friends,

 

Background:  I have a simple test table called pricelist with 4 columns and
only 12 records.

In my card script, I have already set up my table reference to be the global
variable tblPricelist.

 

My problem arises as I am trying out the functions to change a bitset to
arrayset.

 

When I do this:

 

global tblPricelist -- table pricelist

   

   put VTable_SelectAllRecords (tblPricelist) into tBitSetRef

   put VArraySet_FromBitSet (tBitSetRef) into tArySetRef

 

it executes silently in the background, apparently no problem.

 

BUT, when I do this (efDisplay is a Livecode text field):

 

global tblPricelist -- table pricelist

   

   put VTable_SelectAllRecords (tblPricelist) into tBitSetRef

   put VArraySet_FromBitSet (tBitSetRef) into tArySetRef

   put "done" into field efDisplay

 

the execution HANGS!  In fact, ANY command I execute after I use the
VArraySet_FromBitSet() function causes my script to hang.

 

Am I missing something here?

 

Sincerely 

Ng Wee Tong (surname is "Ng".J)
