i’m clueless would somebody explain to me?.

You obviously try to use CGridView or CListView. See the API for examples on how to use these classes.

so if i really was tring to use CListView [of which is what i think i’m using] then what should i do? it’s in one of my classes/models

When I ran into this error message a couple of days ago myself, the problem was exactly matching the error output: my dataProvider variable was empty.

Originally, I wrote: ‘dataProvider’=>$dataProvider’, while I should have written ‘dataProvider=>$model->search()’, since otherwise, I would have had an empty variable. Try to check if you have filled your dataProvider variable with any data.

Cheers,

thanks!.. well…the error just disappeared all of a sudden…lol i didn’t know how and why. :P but anyway thanks… at least i know just in case the error pops up again.

oh yeah btw… you were saying that you wrote ‘dataProvider=>$model->search()’, what were you trying to do here? search the site? :D i’m looking for a way to put a search site on my webapp

In fact it was part of my CGridView - when I tried just the dataProvider, it was empty, because I didn’t initialize it in the correspondent model file, while $model was.

You can check something like I mentioned in the blog demo which is included in the yii package.

But good to hear that your problem is solved by Murphy anyway ;)

yeah… thanks :D
