Re: [CForms] How to set multivalue widget's values ?

[Johannes Textor]

Derek,
I actually don't use the values this way, I insert them directly into 
the database
after the form was submitted.
Let's examine your code though, since you should be able to use the 
values in jxt
as well.

var model = form.getModel();  
 var atheme = model.theme; /* theme is multiselect box */
 cocoon.sendPage("jxpage", { "atheme":atheme, "theme":model.theme });

There is something subtile here. "model.theme" is an object of type ScriptableWidget,
so JXT will be confused when you pass it as a collection. (and print out the "value"
[EMAIL PROTECTED]) 

I suggest retrieving the values to a native JavaScript array and passing that one 
to JXT. 

var model = form.getModel();  
var values = Array();
for( i = 0; i < model.theme.length ; i ++ )
	values[i] = model.theme[i];
cocoon.sendPage("jxpage", { "atheme":values, "theme":values });

Does this work? It's just the solution to my problem applied in the opposite direction 
:)

I have tried what you suggested - the problem
is displaying the results in the JXTemplate - could 
you please post your code snippet, as what I have 
tried does not work....

ie. 

in flowscript:
var model = form.getModel();  
 var atheme = model.theme; /* theme is multiselect box */
 cocoon.sendPage("jxpage", { "atheme":atheme, "theme":model.theme 
});

in jxtemplate:
 <jx:forEach var="thisTheme" items="theme">
   <li>Selection: ${theme}</li>
 </jx:forEach>
 
 <jx:forEach var="thisTheme" items="atheme">
   <li>A Selection 1: ${atheme}</li>
 </jx:forEach>
   
 <jx:forEach var="thisTheme" items="atheme">
   <li>A Selection 2: ${thisTheme}</li>
 </jx:forEach>   

in output html:
Selection:
[EMAIL PROTECTED] 
A Selection 1:
[EMAIL PROTECTED] 
A Selection 2:
[EMAIL PROTECTED] 

I am obviously missing some crucial conversion ?!
Thanks
Derek

Hi Derek + all,
I got this solved in the meantime. Actually I had to create a
temporary
array and then set the multivalue model to this array:
var model = form.getModel();
var rubriken = Array();
for( i = 0 ; i < size ; i ++ )
   rubriken[i] = new java.lang.Integer(val[i]);
model.rubriken = rubriken;
Notice the difference to the code quoted below: Modifying the model
directly did NOT work, as it is actually an object of type widget and 
something
gets messed up. This is because internally, a setter method is called
when
assigning something to model.rubriken. Took me some hours to figure
this
out, as I'm a CForms beginner :)

I think I will put a stripped-down version of my article management on
the
wiki when I'm done - it's based on CForms + Woody + Hibernate and uses
a few more widgets than the present sample.
Derek, you can read values from the model like this:
var model = form.getModel();
var vals = model.rubriken // retrieve array from multivalue widgets
Now, vals is an array which contains all the values of the options 
selected by
the user.

And maybe the same person knows how to
*get* the values from the CForm multivalue widget
and display them using a JXTemplate loop??
A sample showing both of these would be *very*
helpful and (IMO) needs to be  a part of the
Cocoon forms samples.
Thanks
Derek

Hi all,
I'm going nuts trying to set values in a CForm multivalue widget.
I obtained the Form model with:
var model = form.getModel();
Then I tried to set the values like this:
model.rubriken = Array(size);
for( i = 0 ; i < size; i++)
  model.rubriken[i] = new java.lang.Integer(val[i]);
When size=0, everything is fine. Otherwise, I get
Cannot set value of field "rubriken" with an object of type 
org.mozilla.javascript.UniqueTag

When I omit the array declaration, I get null pointer exceptions.
Has anybody done this and can explain me how ?
TIA, Johannes
