evaluation

Here is my script: Note that the --- line below is just for debugging and
I'll remove it soon.

function enable_recurrence_rwp(on) {
---- ${display_rwp} -----------
<if expression="'${display_rwp}' == 'true'">
<![CDATA[

    ${formname}.${rwp_monday.name}.disabled = !on;
    ${formname}.${rwp_tuesday.name}.disabled = !on;
    ${formname}.${rwp_wednesday.name}.disabled = !on;
    ${formname}.${rwp_thursday.name}.disabled = !on;
    ${formname}.${rwp_friday.name}.disabled = !on;
    ${formname}.${rwp_saturday.name}.disabled = !on;
    ${formname}.${rwp_sunday.name}.disabled = !on;
]]>
</if>
}

I invoke the script with display_rwp set to the string 'true'. Here's what
gets rendered

function enable_recurrence_rwp(on) {
---- true -----------

}

Any idea why the stuff inside the CDATA block is not being rendered? I don't
seem to understand how the boolean expression in the expression attribute of
the <if> tag works.

I think you should use <if expression="display_rwp == 'true'">

Basic String comparison.  In java 'true' != 'true' as they are two different 
strings.  you want to leave the quotes off because it's string replacement 
and true == true.
