[TYPO3-mvc] Loading JS files in Extbase plugins: best practice?

OK, good.

Sorry for using the wrong terms, I'm not very familiar with Extbase yet. 
And thanks for educating me :-)

Ah yes, that could be the issue. I'm not sure if it has been solved yet.

In my case I can live with a workaround, load the JS file from the TS 
template and add some additional checks inside it so that it does not 
fire actions in views that don't have the proper elements. It will also 
mean that I can't use $pageRenderer->addInlineLanguageLabelArray() to 
load localized labels. Again I can work around that for now because my 
application will run in a single language (phew! ;-) ), but it's an 
embarrassing issue and I'll try to find more information.

Thanks
