The problem you are having is the nature of JSF and postbacks.
In your example. lets say it is initially disabled.
1. user clicks checkbox
2. you submit the form
3. decode the checkbox and inputtext (which is disabled)
4. validate checkbox (no validation on the disabled inputText)
5. update the checkbox value
6. re-render the page
This process should work for you if you aren't worried by validation errors.
If you are worried about validation errors, make the code that submits the
form immediate.
If you are using trinidad, try this:
<tr:document>
<tr:form>
<tr:selectBooleanChechbox
id="myCheckbox"
label="Select me to enter text"
value="#{bean.test}"
autoSubmit="true" />
<tr:inputText
disabled="#{not bean.test}"
value="#{bean.test2}"
partialTriggers="myCheckbox" />
</tr:form>
</tr:document>
Note that if the inputText is disabled, it will not update so the test2 in
this case will remain in its current value. So if you want it to be null
when disabled you would need to have it be set to null in the bean's
setTest(boolean) method, or add a listener to the checkbox to do it.
Now if you start having validation problems, you need a way to only
update/validate the checkbox. In this case I would recommend that you use
the tomahawk subForm component and wrap it around the checkbox.
