             Summary: Error in reading Array
                 Key: PLC4X-262
                 URL: https://issues.apache.org/jira/browse/PLC4X-262
             Project: Apache PLC4X
          Issue Type: Bug
          Components: Driver-S7
    Affects Versions: 0.8.0
            Reporter: Stefano Bossi


Dear developer,

after the commit [ Improve the reading of S7 Date and Time 
handling|https://github.com/apache/plc4x/commit/9c25eb319f5c4e9192d4fc6a4abf5bedc3838c0c]
 I have found that reading array raise an exception. 
The code I am trying to use is the HelloWord:

{code:java}
try (PlcConnection conn = manager.getConnection(connectionString)) {
    if (conn.isConnected()){
        PlcReadRequest.Builder builder = conn.readRequestBuilder();
        builder.addItem("PollingValue", "%DB2:126.0:INT[2]");
        // builder.addItem("PollingValue", "%DB2:114.0:INT");
        PlcReadRequest readRequest = builder.build();
        PlcReadResponse syncResponse = readRequest.execute().get(2000, 
TimeUnit.MILLISECONDS);
        printResponse(syncResponse);
    } else {
        logger.info("PLC is not connected, let's try to connect");
        conn.connect();
    }
}
{code}

and the exception is: 

{noformat}
[INFO ] 10:58:21.274

        at it.fox.datapicker.HelloPlc4x.main(HelloPlc4x.java:43) [main/:?]
{noformat}

If I try with the simple 
{code:java}
builder.addItem("PollingValue", "%DB2:114.0:INT");
{code}

Everything works.

Stefano Bossi
