netPROXY object used to map structure has inconsistent data

Bug Description from Tester:

 netProxy object representing OPC structure  change  the total and structure length after OPC client write some data to this structure.

Steps to Reproduce:

May use the attached project.

OPC configuration contains structure with byte array[50]

Structure is mapped and represented by object 0x4000000D

UAExpert OPC client  monitor this structure.

Check object 0x4000000D. ( All elements ). Read Object REQ:   0x00008840     00 00 00 00 0D 00 00 40 00 00 00 00 FF FF FF FF

UAExpert OPC client write some data to the structure.

Check object 0x4000000D again. ( All elements )  Read Object REQ:   0x00008840     00 00 00 00 0D 00 00 40 00 00 00 00 FF FF FF FF

Expected Results

All elements except the changed data value  are the same.

Actual Results

Structure total  length and data length are different  between both reading and become correct after OPC client write some data.
