Subject Re: Looking for open source projects that uses the current version of Tapestry
Date Mon, 08 Jul 2019 18:09:41 GMT
Try:
<t:form>
    <t:textfield value="channelName"/>
    <t:submit/>
</t:form>

"t:id" specified the name of component. You could use it to inject the
component in Java like this:

tml:
<t:textfield t:id="channelNameField" value="channelName"/>

java:
@InjectComponent
private TextField channelNameField;

but usually you don't need to inject individual fields, unless you want to
add some custom validation errors.

Best regards,
Cezary Biernacki
