Yii framework - picking up field value from other model -

-

i have been struggling this, have 2 models , showing data in cgridview 1 model, model contains id's values in different table

so, have added

'value'=> 'tblareaoflaw::model()->findbypk($data->typeoflaw)->areaoflaw'

which giving error

"trying property of non-object"

might due reason records doesn't exist in tblareaoflaw. can't check in line through isset?

when put static value, work well, like

'value'=> 'tblareaoflaw::model()->findbypk(5)->areaoflaw',

could please help

thanks lot

the error because expression tblareaoflaw::model()->findbypk($data->typeoflaw) returning null. means trying null->areaoflaw won't work (this error message "trying property of non-object" clarifies).

my best guess $data->typeoflaw returns non-existing primary key tblareaoflaw model.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
