Subject: [PATCH] Workaround for std::logic_error in 00.08.00
Issue:
Server throws when there are no device module variables:
terminate called after throwing an instance of 'std::logic_error'
what(): ReadAnyGroup has no element with AccessMode::wait_for_new_data.
Aborted (core dumped)
This commit introduces a workaround as proposed by jens:
void DoocsUpdater::updateLoop(){
if (_elementsToRead.empty()) {
return;
}
This commit is intended to be reverted if the above strategy has side
effects.
