in the last few months I gathered a bit of experience in creating component,s so I thought it might be useful to others to (try to) summarize what I learnt.
I wrote the first part of the tutorial, you can find it here, I just went through the basic concepts so far, but indeed I may expand to more advanced ones if someone finds it useful.
The page can be found here : http://www.powerupbi.com/talend/componentCreation_
Please feel free to send remarks, suggestions etc.
part 3 of the tutorial is out :
Sorry you will have to be patient for part 4, as I will be traveling starting today for about one week.
