Qt Translation returns the same string instead of translation

Question

Qt Translation returns the same string instead of translation

I am having a weird Qt translation problem.

Due to reasons that I cannot change that are related to outdated translation table databases, our "natural language" is Enumerations.

QString myString = tr("OUR_APP_MY_STRING");

I have a script that creates * .TS files from our databases that Qt will use.

The entry in * .TS files for English is as follows:

<message>
    <source>OUR_APP_MY_STRING</source>
    <translation>My String</translation>
</message>

The * .TS file is uploaded to Qt Linguist. Everything looks great there. "OUR_APP_MY_STRING" is found and its "English translation" looks fine.

The QT project file has * .TS files in TRANSLATION sections. I use lRelease to create .QM files and place them in the application resource file (.qrc).

( main() ) :

// initialize translator
this->currentTranslator = new QTranslator(instance());

if (this->currentTranslator->load(":/translation/myApp_en.qm"))
{
  this->installTranslator(this->currentTranslator);
  QString test = tr("OUR_APP_MY_STRING");  // <<----- problem. output is always "OUR_APP_MY_STRING"

}

?
