Intake & initial values

[Scott Eade <se...@backstagetech.com.au>]

I have a form that I validate with intake that I 
would like to provide initial values for some 
of the fields.  I have tried setting the intake 
field values thus:

  #set ($group.Active.Value = true)
  #set ($group.StartDate.Value = $today)

but this doesn't seem to work.

Is there some way of initialising intake field values?

Thanks,

Scott

Intake takes initial values from the objects attached to the groups
through the method "mapTo".  Setting initial values the way you are
attempting to would be a good thing to support.  I will keep it in mind
or feel free to add the functionality.

I agree, so of course this way will not work.

I too mostly reference the object that contains the values, but
in this case it is for a new instance of the underlying object and
I am thus using the Default intake group.

Apart from delving into the intake code (which unfortunately
I do not have time for right now) the only other solution that 
comes to mind involves retrieving a reference to a new instance
of the underlying object and populating it with the default values 
before mapping that to intake.  I haven't tried this yet as it seems
like a bit of a hack.  Intake also seems to use the primary key
as the key value so I am not sure how this will be handled.

Thanks again for your comments.
