Hi
I just stumbled upon a problem I don't know how to solve: I have a kendo Scheduler with a DataSource, that uses a field-model with relation definitions (f.ex. foo: {from: "Name"}). This works like expected, if the data is delivered by ajax or hard coded when executing the script. But when i set new data (can even be the same as before) with DataSource.data(myData), the relation Model seems not to be used anymore. This is also the case on other widgets. f.ex. I tried this with ListView and a template as well, where the template finds the entry "foo" which was defined as a relation when I create the DataSource, but is missing it, when I set the new data. I double checked the relation definition and could not find an error.
Someone has an idea? Or is this a bug?

Hello Patric,
The behavior you described is expected - when the data is passed through the data method it will be processed via model parser. In other words the dataSource expects already parsed and ready-to-use objects.
If possible please try to manually parse the data objects before passing them to the data method (e.g. instead of having "Name": "Name 1" directly change it to "foo": "Name 1"). In case this approach does not fit in your scenario please provide a better description of your scenario (why data is first loaded via Ajax transport and after that replaced via data method) so I can advice you accordingly.

Hi Alexander
Thank you for your help. In this case I will have to way until I can call the data by ajax (testing with local objects at the moment). But this is a good thing to know for me :)
