Aptana does not provide auto complete list for class with type (CApplication) came from Yii::app()->
I noticed that the problem was not with Yii itself , it is with case
class::func()->
also in
self::$x->
in the previous two cases , Aptana PHP processor fail to detect variable type and function return type to give autocomplete list, and you will lost an important feature.
I modified the plugin file com.aptana.editor.php to correct this bug , then , exported the new package ,
replaced the new plugin file with file older one com.aptana.editor.php_3.3.0.1365773524.jar
where the text after _ refer to file version , and may change according to updates you made.
You may find multiple files with different versions (com.aptana.editor.php.*.jar) ,and the newer file will be the used one
Steps to install the new Plugin:
[list=1]
[*]download new file from attachments , extract the zip archive
[*]Copy the file to aptana plugins folder in aptana installation.
[]find the file com.aptana.editor.php..jar
[*]copy file name (file name only)
[*]delete the file
[*]rename the file com.aptana.com.aptana.editor.php_new.jar to the copied one.
[/list]
And notice the change
