I have been suffering and trying many times to create a really simple project with primefaces from tutorials. I have done a lot of them and all of them don`t work for me.

I have been working with primefaces, and the sheet component meet most of the requirements that I need to accomplish my work, did some research and added contextual menu and other functions, but my main problem is visual, if I put some columns fixed, and I move to the right all the rows are resized automatically, I have decided to avoid the fixed columns but anyway if I move the cursor a few columns to the right the row’s height is resized.

I guess this is a similar problem as described in this question.
In my case I open a Dialog which, when it is closed, should download a file and then close aftwards.
