how to hide a field when user creates new replicant

I've got a replicant element that defaults to 6 instances when a DCT is first loaded. The replicant element includes several fields, one of which I want to have hidden on the form. For each of these 6 default instances, I am able to hide the field using FormAPI when the DCT is loaded.

However, if a user creates a new replicant (by clicking the + button), the field is not hidden in the new replicant. I want to hide it, but I'm not sure how. The only FormAPI command I can think of is the onItemChange, but I can't find any examples of how to construct this event handler on a replicant itself (rather than an individual field).

I'd appreciate any examples or advice anyone has. (TS 5.5 on AIX)

Could you not hide the item using the <hidden /> tag like this, if for example you needed EmpID hidden?

<replicant max="10" default="6">
<container name="A" hide-name='t'>
<item name="Name">
<database data-type='VARCHAR(90)' />
<text required="t" size="23" maxlength="23" wrap="virtual" />
</item>

<item name="EmpID">
<label>Employee ID</label>
<hidden />
<database data-type='VARCHAR(90)' />
text required="f" size="23" maxlength="23" wrap="virtual" />

</replicant>

I am also having trouble with a field that sometimes needs to be hidden, and whenever a new replicant is created it contains the field which should be hidden. The only thing I could think of to hide it would be if you had a "total" field which would be a sum of the amount of replicants and attached an OnItemChange to this, so that whenever a new item is added, it runs the "hide item" script you described. Sadly I haven't been able to see if this works yet - sorry!. Hope this is some help...
