DependentInput does not populate default values.

When you use an input field inside DependentInput and mention a defaultValue, the value is not filled:

Instructions:

1. Click on Comments
2. Click on Create
3. Click on Show Dependent.

The dependent field has a default value but it is not shown.

I found that setting the default value on the dependent input instead and setting the source, will correctly set these props and propagate them to the nested input. E.g.:

<DependentInput source="appointmentTimeslot" dependsOn="planned" defaultValue={1}>
    <ReferenceInput source="appointmentTimeslot" reference="timeslots" allowEmpty={true} >
        <SelectInput optionText="name" optionValue="id" />
    </ReferenceInput>
</DependentInput>

@pimschaaf Yes I checked and your solution is working but it is still a bug as it is a hack which will solve the problem when we have one field. In case of multiple fields we can not specify multiple sources or default values in dependent input.

@anuragagarwal561994 I don't think <DependentInput> is meant to be wrapped around multiple inputs. @djhi can you confirm?

Using multiple dependent inputs, each wrapped around only one input, should work in your case.

[anuragagarwal561994]

@pimschaaf I agree that from the examples it is not clear for dependent inputs to be used for multiple input elements. But won't it make sense, because I usually have more than 1 field, so instead of writing separate dependent inputs for them it is much clearer for me to write a single dependent input wrapper and place multiple components.

But I surely agree that it can be another way of seeing DependentInput, may be I got confused. At present, multiple input thing works inside DependentInput component but default works in your way but for a single component.

You can wrap multiple children inside a single DependentInput. I'm trying to figure out why the defaultValue is not working

wish this got resolved soon

[djhi]

We're looking for a solution for this. Stay tuned :)

Should be resolved once https://github.com/marmelab/admin-on-rest/pull/913 is finished

This is resolved in the next branch of admin-on-rest which will be released as 1.3.0
