suppress element on one table row only?: msg#00017

Subject: suppress element on one table row only?

I know this is a classic difficulty with XMLC, but I suspect there’s a better solution out there than I’ve seen so far:

 

The issue is how to suppress an element (with children) on one table row (say the first) and have it re-appear on subsequent table rows? 

 

I see several options:

 

1. generate the element programmatically, and only add it to the DOM tree for the rows in which it needs to appear

2. have the element in the mockup.  Clone it before your loop begins and remove it from the tree.  Insert the clone back when necessary.  Pro:  this keeps the mockup in it’s desired role: as the source of the element. Con: I can’t get this to work! (DOM006 errors)

3. somehow disable the element for one row only, so it stays in the tree but doesn’t get inserted in the page.  I don’t know if this is supported, but I think this would be the ideal extension to XMLC.

 

 

And a related question:

 

My loops to iterate thru table rows typically look like:

 

page.getElementTableRow();

while(…)

{

            // modify table row as needed

 

            table.appendChild(templateRow.cloneNode(true));

}

 

I do the cloning at the end because the only way to use the nifty XMLC-generated accessor methods (getElementXXX()) is to access them from the page. Having these accessors seems the primary value of XMLC, and traversing the DOM manually seems to undermine the argument for using XMLC at all.   If somehow XMLC could generate an object for the row itself, with methods for the row’s child elements, this would no longer be necessary.

 

The downside is that I cannot remove elements from the template row temporarily.

 

Do others typically clone at the end of the loop, or do you clone at the beginning and then traverse the DOM of the cloned row manually?

 

Thx!
