Could you please provide a sample application to reproduce the issue? The actual server in GitHub does not allow to change the array dimension by the client.

Hello Alex,

The issue can be replicated with the actual version of the .NET Standard ReferenceServer from Github.
It replicates by simply running the Deadband Filter/Test Cases/015.js against the server.
The script will set the “Static/All Profiles/Arrays/Byte” to null instead of changing it's size as intended.
The CTT project used for testing is also check in to the following location : https://github.com/OPCFoundation/UA-.NETStandard/tree/master/SampleApplications/Workshop/Reference
I sent you an e-mail with a detailed report about this issue on "Tue 9/26/2017 3:12 PM" but maybe it was lost somehow. I will resend it now...

Thank you,
Alin

I did find the problem and fixed it. Please go to the Library/ClassBased/UaB.js:
Search for Line146:
UaByteString.FromByteArray = function( bytes ) {
And replace the for loop starting at line 151 with this one:
for (i = 0; i < bytes.length; i++ ) {
x = bytes[i];
if( x < 16 ) str += "0";
str += x.toString(16)
}
This is fixed in Version 1.3.340.378
