[Nant-users] Problem with readonly attribute on property

[Rod Ayers]

I have a "top-level" build file in which I initialize several properties.  It then calls a task in another build file <nant .../> that reads a properties file, updating properties previously initialized.  I want to make sure that properties updated from the property file don't get overwritten anywhere in the script, so I tried teh following:

 

 

     <foreach in="${build.file.properties}"
      item="Line"
      delim="="
      property="property.name,property.value"
      >

 

    <!-- property.name must not be empty -->
      <if test="${property.name > ''}">

 

     <!-- property.name must not be a comment -->
           <if test="${not string::starts-with(property.name, '#')}">

 

      <!-- property.value must not be empty -->
            <if test="${property::exists('property.value')}">

 

           <property name="property.name"      value="${string::trim(property.name)}"/>
           <property name="property.value"      value="${string::trim(property.value)}"/>

 

           <echo message="Adding property = value:         ${property.name} = ${property.value}"/>
           <property name="${property.name}"                   value="${property.value}" readonly="true" />

        </if>

 

       </if>

 

      </if>

 

   </foreach>

 

Everything weorks fine, except the readonly attribute is bein ignored.  I had one property in the property file, build.number.  But, right after the foreach, I was able to set build.number to a different value with another property statement, withouth an error or waraning.

 

If I set readonly on the original property statement, any attempt to update the value results in the warning message:  Read-only property "build.number" cannot be overwritten.

 

Why doesn't readonly="true" work when I change the value of an existing property?

 

Thanks,
