Changing the readOnly attribute of fields in a JHeadstart generated table

Question

Hey Folks,
I'm trying to set the readOnly attribute on a bunch of fields in a jheadstart generated uix table based on a http request param, using a <boundAttribute>. For some strange reason, the value of the param is ALWAYS seen as true within the table, no matter what the param actually is set to. I have other fields that are NOT part of the Jheadstart generated table, and it is working fine. However, when I try and apply the boundAttribute to the uix table, the readonly attribute is always seen as true. Why is this? Wouldn't the http request param be the same throughout the page no matter if it was in a uix generated table or not? What am I doing wrong? I'm using Jdev 10.1.2 and Jheadstart 10.1.2.2, using struts/uix.
Thanks!

Sure. First, note that this page submit to itself. Previewmode is a request param that gets toggled to true or false each time the page loads through a seperate boundAttribute.
Here is the code for one of the fields on the uix table:
<messageTextInput id="${ui:concat('DetailsInClaim:ProcRevDrug:',uix.current.tableIndex)}"
model="${uix.current.ResubmitProcRevDrug}"
text="${uix.current.ResubmitProcRevDrug}"
name="ProcRevDrug"
promptAndAccessKey="&amp;Procedure / Revenue"
rows="1"
maximumLength="12"
columns="5">
<boundAttribute name="readOnly">
<if>
<not>
<comparison type="equals">
<convert javaType="string">
<dataObject default="${!param.previewMode}"/>
</convert>
<fixed text="true"/>
</comparison>
</not>
<fixed text="true"/>
<fixed text="false"/>
</if>
</boundAttribute>
</messageTextInput>
However, our consultant figured out that applying the value of ${param.previewMode} directly to the readOnly attribute WITHOUT using a bound attribute actually worked. (within the messageTextInput tag do readOnly="${param.previewMode}"
Not sure why that would work as when a <boundAttribute> would not.
