Hi everyone. I have created a nodelet which inherits from diagnostic_aggregator, and i try to load some Analyzers, but i am getting the following error:

[ERROR] [1455701271.351054532]: Unable to find Analyzer class "ros_pkg_name"/"my_analyzer_name". Check that Analyzer is fully declared.
[ERROR] [1455701271.351182915]: No analyzers initialzed in AnalyzerGroup /"ros_pkg_name"/analyzers
[ERROR] [1455701271.351207463]: Analyzer group for diagnostic aggregator failed to initialize!


I need to note that the analyzers were tested and properly loaded to a common diagnostic_aggregator, but not in the nodelet which inherits the diagnostic_aggregator. Is it configuration or implementation problem? I took a look in github in the diagnostic_aggregator/aggregator code and i have realized that my code crashed in the AnalyzerGroup::init, in the following code section:

if (analyzers_.size() == 0)
{
init_ok = false;
ROS_ERROR("No analyzers initialzed in AnalyzerGroup %s", analyzers_nh.getNamespace().c_str());
}


where analyzers_ the analyzer vector read from ROS Parameter Server. This means that no analyzers are retrieved for my nodelet.

Also reading the code, i have noriced that when the analyzer group is created for the diagnostic_aggregator, the analyzer base path is given hard coded:

AnalyzerGroup::AnalyzerGroup() :
path_(""),
nice_name_(""),
