php - In Propel2, filter crossref by null value -


i use propel2 orm.

i've 2 tables entry , category connected many-to-many relationship via entrycategory table.

i set iscrossref on true in schema.xml.

everything works fine : i'm able filter entry category :

entryquery::create()->filterbycategory($cat)

but

i'm not able filter entries with no category. tried 

entryquery::create()->filterbycategory(null, criteria::equal)

or

entryquery::create()->filterbycategory(null, criteria::isnull)

but, gives me

'filterbycategory() accepts arguments of type \category or collection'

i tried

entryquery::create()->where('category null')

but, i've got error

unknown column 'category' in 'where clause'

so, need ...

edit :

extract of schema.xml :

you need use id or name or whatever column name is.

->filterbycategory expects propel object of category type.
->filterbycategoryid() or whatever name actual column is. (having schema beneficial)

not passing sets null. else handled string literal. where column = 'null'

use either ->filterbycategory() (if name of column , not foreign key reference) or ->filterbycategoryid() if 'categoryid' 'phpname' of column.
