Re: Palette component

2009-02-18 Thread jgn 

I had the same problem. I am not sure what of the 5 things I did was the one
that help, but what I did was:

Implements Serializable
Implements Comparable
Override equals
Override hashcode
Override toString

I am not sure how is implemented the Pallete, but most of the time is a good
practice to implement this methods or override them if you are going to use
your beans with other components. 

Serializable: so the components can serialize them, logic :D
Comparable: It is used to reorder your beans on a list, or other things
equals: well, how would other classes or components would know if one of
your beans is equals to other if you do not override this ?.
Hashcode: Used on some kinds Maps, lists, etc, to get faster searches, or
something like this.
toString: well, u know

I said that some OptionModel seemed to be *null*. I didn't say that
the list of OptionModels was *empty*.

By the way, the code you posted seems to be right.

RE: Palette component

2009-01-27 Thread James Sherwood 
Hello,

I just ran into the same problem.

You are probably creating the available and select lists in 2 different
methods, you need to do it in the same method with the SAME object(or at
least with a list that doesn't reload when you pull your select) otherwise
you get that null error(or at least that was my problem) because you are
basically handing your palette objects in your select that do not exist in
your available.

I was using the GenericSelectModel from the JumpStart object select that you
use as both your encoder and model.

Not sure if it's the same problem that I was having but it sounds alot like
it. Posting your java may help.

 One of the parameters of Select is model. You should pass a  
 SelectModel to
 it. Basically, a SelectModel is a list of OptionModel instances
 (SelectModel.getOptionModels()), one for each option to appear in  
 your
 select tag (and component). Select does not support null  
 OptionModel's
 returned by SelectModel.getOptionModels(), so the exception you seen
 happens.

 Summary: make sure the SelectModel returned by getCategoryModel()  
 does not
 return nulls in its getOptionModels(). ;)

Re: Palette component

2009-01-27 Thread Davor Miku 
I'm using AbstractSelectModel, and ValueEncoder interface.

Palette is internally using two lists: one for available options and one for
selected.
Problem was I needed to change available options (for presentation purpose)

So, selectedSet.contains(value); (from Pallete.java) retuned false even if
'value'  is contained in selectedSet (available options).

I don't know if I'm beaning clear.
All lists contain objects of bean Category. Two categoies are equal if they
have same id property.
Besause I chaned name propery of available categories, selectedSet.contains
returns false even if categories have same id.

So, If you have similair problem just override equeas and hasSet methods of
bean (bean in my case)
in maner that suit your needs, and everything will work ok.

Hope this helps.
