FormAPI - Accessing replicant?

Adam Stoller

TeamSite 5.5.2 SP2b + patches, on Solaris 8

I have a DCT with a structure like this:

...
  <ruleset ...>
    ...
    <item name="Generated Content Type">
      ...
    </item>
    <container name="gen_info">
      ...
    </container>
    <container name="orgsubnav_links">
      ...
    </container>
    <item name="addlinks">
      ...
      <replicant min="0" max="5" default="0">
        ...
        <item name="title">
          ...
        </item>
        <item name="url">
          ...
        </item>
      </replicant>
    </item>
  </ruleset>

I'm working on some FormAPI code (something I've only done marginally in the past), but running into problems trying to access fields within the "addlinks" replicant - and I'm sure it's something simple, but rather than waste too much more time on this myself, I figured I'd check with you folks to see if you can pinpoint my mistake.

var tmp = IWDatacapture.getRootItems();
alert("tmp length: " + tmp.length); // => 4
for(i = 0; i < tmp.length; i++){
  alert("["+i+"]: "+tmp[ i ].getName()+" ("+tmp[ i ].getType()+")");
// => [0]: /Generate  Content Type (select)
// => [1]: /gen_info (andcontainer)
// => [2]: /orgsubnav_links (andcontainer)
// => [3]: (andreplicant)
}

I'm trying to figure out why there's no 'name' associated with the replicant. While I could access the replicant information via tmp[3].getChildren() I'd much rather be able to access it through IWDatacapture.getItem("/addlinks").getChildren() - but that doesn't seem to work. Any ideas?

Hmm, don't know the answer to your specific question. But here's the approach I've always used to access replicants via FormAPI. It's a bit brute force, but it works

 
for (i = 1; i < = 5; i++)
{
    var title = IWDatacapture.getItem("/addlinks[" + i + "]/title");
    // check to see if this replicant item actually exists
    if (title == null)
    {
        // stop the loop, we've reached the last intantiated replicant
        break;
    }
    var url = IWDatacapture.getItem("/addlinks[" + i + "]/title");
    // Do something with title and url
}
