[Laszlo-user] datasets not in canvas file

[cem sonmez]

hi
i have a dataset and a datapointer like :

<dataset name="datasetLogin">
        <person>
            <firstname>cem</firstname>
            <lastname>sonmez</lastname>
        </person>
</dataset>

<datapointer name="datapointerLogin"  xpath="datasetLogin:/"/>

my problem is that :
when i create "datasetLogin" in the file which includes *canvas* tag,
everyhing goes fine.
But when i write the same dataset in another class file, compiler tries to
find the dataset like : canvas.datasets['datasetLogin' ].
Can't we create datasets in the classes except canvas file ?
