Hi,
You can definately do this, in your .vm file you must:
* get a handle to the group and bind it to your Java bean. e.g.
$TaskTemplateBean.setQueryKey("_0")
#set ( $TaskTemplateGroup =
intake.TaskTemplate.mapTo($TaskTemplateBean) )
* In your form vars, display the values:
<input type="text" maxlength="255" size="50"
name="$TaskTemplateGroup.Description.Key"
value="$TaskTemplateGroup.Description.Value">
Your screen (Java) class just needs to put a blank-ish Java bean in the
context so Intake can map the values to it.
...
TaskTemplate tt = new TaskTemplate()
context.put("TaskTemplateBean", tt);
Hope this helps.

Subject: Re: Intake group fields don't get populated from
ParameterParser
The problem is this:
I have a form, people enter values and submit, if there is an error I would
like the form fields to be pre-populated from whatever
was entered rather than typing the form all over again. Is there any way
Intake can help. For example: if I say
<input type="text" name="$docGroup.Name.Key" value="$!docGroup.Name"> will
the value be retained with what was submitted. Or do I
have to say $data.parameters.getString($docGroup.Name.Key)?
The problem is not that I have to write this function but during
modification of object attributes. In that case, the first time the
data should be populated from the bean but later on from the parameter
parser. For example let's say that Description attribute was
"foo", so the first time the form screen will show "foo" in the text box.
Now the user changes it to "bar" and submits and lets say
that there was an error in a different field so that the form gets shown
again. However, we still want "bar" to be shown, not foo.
If there was a way to specify how the group gets populated from a parameter
parser (we already know howfrom Bean) this problem can
be solved very easily.
Am I making sense?
Thanks.

:
: No. You must create an instance of the IntakeTool, retrieve your Group
and
: then explicitly call the Group.setProperties(Retrievable).
:
: Group.setProperties(Retrievable) where Retrievable is the Object to which
: you want set the values of based on the form data. It is EXTREMELY
: important that the java object you are trying to map values into
implements
: the Retrievable interface or this will not work.
:
: Also, some code would also be nice to help us assist you in the debugging
of
