Try using preserveRowStates=true on your t:dataList and see if that
fixes the problem. There's some odd behavior of UIData component
state saving that still needs to be addressed for JSF 1.1.

We're using MyFaces with Tomahawk and are seeing some strange behavior
that appears to be related to t:dataList and certain types of form
elements.
Suppose you have a form with code like this:
...
<h:selectBooleanCheckbox value="#{myBean.boxNotInDataList}"/>
...
<t:dataList value="#{myBean.things}" var="oneThing">
...
<h:selectBooleanCheckbox value="#{oneThing.boxInDataList}">
...
</t:dataList>
...
Note that one checkbox is outside of the dataList, the other is inside
the dataList.
Suppose I were to do this:
* display the form
* select both checkboxes
* click submit
I would find that the value of the checkbox that is inside the
t:dataList is ignored -- the value of myBean.boxInDataList would NOT be
set to "true". The checkbox outside of the t:dataList would work just
fine.
Stranger still, if I were to:
* display the form
* select both checkboxes
* do something that will cause a validation error (e.g. leave a
required field blank)
* click submit
Then I would find that when the form was redisplayed with the
validation error message, the checkbox within the t:dataList would NOT
be checked. The checkbox that is outside of the t:dataList would
properly remember that I had checked it.
Strangest of all, if I were to:
* display the form
* select both checkboxes
* do something that will cause a validation error (e.g. leave a
required field blank)
* click submit
* observe on the redisplayed form that the checkbox in the
t:dataList is not checked
* reselect the checkbox
* correct the validation error
* resubmit the form
Then I would find that the value of the checkbox in the t:dataList is
NO LONGER IGNORED.
What the...?
Is this a bug in MyFaces Tomahawk or is there something subtle going on
here that I'm missing? We've seen similar behavior from t:commandLink
and t:inputFileUpload when they are inside t:dataList.
We're using MyFaces 1.1.3, Tomahawk 1.1.2, Java 5, and Tomcat 5.5.
