-----------------------------------------
Summary: modbus: Future which writes data correctly in modbus does
not return
Key: PLC4X-159
URL: https://issues.apache.org/jira/browse/PLC4X-159
Project: Apache PLC4X
Issue Type: Bug
Components: Driver-Modbus
Reporter: Alvaro del Castillo
When writing data registers in modbus, the data is written correctly but the
Future which does it does not return. The hack is just to not wait for the
Future because you don't need the results. Just that the data is written. But
if there are some error during the writing you don't know it. And probably the
resources are not freed correctly.
Some sample code:
{code:java}
PlcWriteRequest writeRequest = connection.writeRequestBuilder()
.addItem(registerName, "register:" + offset + "[" + size + "]", writeRegister)
.build();
writeRequest.execute().whenComplete((writeResponse, error) -> {
assertNotNull(writeResponse);
});
{code}
The whenComplete is never called. I have follow the code and the "decode"
method is called, so it is when processing the response from the modbus slave
where the problem is.
