Yes, REST is definitely simpler. I'm not too familiar with JavaScript.
Let me explain what I'm trying to do...
I have two SQLFORM.grids on the same page. The user clicks on one row of
one grid to add that row to the other grid. A simple enough application
pattern.
Just like when you click on "delete" to delete a row from a grid and the
grid automatically updates on the page, I want something similar to occur
here.
Now, this works fine as far as it goes using "links" and REST. However, if
the first grid has pagination and you're on, say, the third page, I'd like
to preserve my place (ie, stay on page 3) when the page is updated. It's
not a big deal, I guess. The user will have to manually go back to where he
was before.
