@SkyFoxvn Friendly ping

sorry about the delay
i just checked that but im not sure thats the solution sure maybe it will work depending of few thinks for example if we are working with single tone PropelDataCollector but if we are making new instance of this class you will get printed only the instance queries not all queries as in the previous case ussing logger->getQueries

also another think is if you check the logger class PropelLogger -> getQueries you will easy see that function cant return anything else then array so the problem is somewere else please provide me with more information so i can reproduce the problem and find what happens

NOTE: i will look it after the new year but still i will need more info to reproduce it

@SkyFoxvn Sorry, I edited the wrong line, You're right. I updated the PR.

I believe the regression comes from adding the hint type to the "getQueries" method in the commit 58fa12e#diff-53d4d12dd850e3a771f9af985f2fea723cbbaee3f0d3509da76ab67404a0c05b

You can reproduce it by going to the profiler panel, you should have the error An exception has been thrown during the rendering of a template ("Propel\Bundle\PropelBundle\DataCollector\PropelDataCollector::getQueries(): Return value must be of type array, Symfony\Component\VarDumper\Cloner\Data returned").
