Multiple connectors and group about thingml

[vassik]

I get the same issue, here is the code snip where i get this:

//alarmpsm.thingml
configuration fragment AlarmPIMMQTTConfig {
    instance mqttalarmpsm : MQTTClientPSM   
    instance alarmpim : AlarmPim

    connector alarmpim.mqttport => mqttalarmpsm.mqttport
}

//alarmpim.thingml
configuration AlarmGatewayTest
  @output_folder "/home/tmp/"
  @add_c_libraries "paho-mqtt3a tmlmqtt cson"
{
    group alarmmqttpsm : AlarmPIMMQTTConfig 
    instance gateway : GatewayImpl

    connector gateway.alarmSirene => alarmmqttpsm.alarmpim.sirene
    connector gateway.alarmAlert => alarmmqttpsm.alarmpim.alert
    connector gateway.alarmMonitor => alarmmqttpsm.alarmpim.monitor
}

for the second and third connector in AlarmGatewayTest, the following error pops up

Description Resource Path Location Type
An expection occured while resolving the proxy for: EMFTEXT_INTERNAL_URI_FRAGMENT_14_alert. (java.lang.NullPointerException) gateway_g2_test_config.thingml /ThingMLSamples/thingmlg2demo line 22 EMFText Problem

@Lyadis this one you should look into in priority.

Seems like an EMFText issue... do we have good motivations for keeping this group concept or should we re-think it a bit? @Lyadis is going to write a few tests.

[brice-morin]

Well, it is useful e.g in the case of Anatoly, as it makes it easy to include a pre-configured PSM fragment into a PIM model, without polluting the model with the PSM details. Then it is more in the methodology we should advise people to use it wisely.

After some tests, it appears that the problem happens only when the fragment configuration is in a separated file.
Indeed when both configurations are in the same file, the compiler doesn't complain.

[brice-morin]

Ok. Can you create proper test cases for both cases, so that we can have them included in the test suite.
