Indeed it should. I didn't check all the code I copied.
If you use an expansion ${color}, just the value of the property color
gets inserted there and Tapestry doesn't has access to the property
color. This was the first error reported in this thread.

I haven't ever seen anything like value="${teste}" in the tml either.
I think that should just be value="teste". You used the @Property
attribute in your java page so tapestry will magically create your
getter and setter. Tapestry will then use that getter and setter for
the value.
For a good example of how to use checkboxes and radio buttons take a
look at this page example:

Hello,
while I've never worked with the Radio Component before, I assume
from the URL I provided to you that it should look like this:
Class:
-----------------------------------
[...]
@Property
private String currentColor;
@Property
private String chosenColor;
[...]
void onSubmit() {
System.out.println("aqui.........: " + chosenColor);
}
[...]
-----------------------------------
Template:
-----------------------------------
<form t:type="form" t:id="myForm">
<input t:type="submit" t:name="${teste}" value="${teste}"/> ${teste}
<br/>
<t:radiogroup value="chosenColor">
<t:loop source="colors" value="currentColor">
<t:radio value="currentColor"/> ${currentColor}
</t:loop>
</t:radiogroup>
<br/>
<input t:type="submit"/>
</form>
-----------------------------------
Code is untested and maybe needs to be tweaked a bit.

I have three items: Blue, Green and Red.
So I want to print the value of "Colors" by selected item.
I need simple example.

Hello,
I'm not seeing where you are using the Radio Component?
I suggest you take a look at
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Radio.html
and combine it with your loop.
Hope that helped,
Tobias
