Is array-referencing syntax allowable when using javascript?

Question

Is the array-referencing syntax notation allowable when using javascript as the calculation language?  My hierachy looks like the following:<br /><br />    . form1<br />        . Area[0]<br />            . numHeight<br />            . numWidth<br />            . numDepth<br />        . Area[1]<br />            . numHeight<br />            . numWidth<br />            . numDepth<br />        . <etc><br /><br />Without getting into too many details, my need is for fields in the "Area[2]" container to access fields in the "Area[0]" container.  E.g. "this.rawValue = form1.Area[0].numHeight.rawValue;".  With this syntax, I received the following report:<br /><br />Generating PDF Document...<br />Script failed (language is javascript; context is xfa[0].form[0].form1[0].Area[2].numHeight[0])<br />script=this.rawValue = form1.Area[0].numHeight.rawValue;<br />   Error: Invalid property get operation; subform doesn't have property '0'<br />PDF generated successfully.<br /><br />1 warnings/errors reported.

You can use resolveNode on basically anything, so yes you can access the record nodes within the xml data source. The function assist does not have anything when you do record but the nodes are created under record to match the nodes in your XML data source.
I am not sure of what you are trying to do with your example - if you want to return a list of nodes match some expression, then there is another version of resolveNode method which does just that called resolveNodes()
For example if you want to find all conditions_item nodes you would have:
xfa.resolveNodes("xfa.record.conditions.conditions_item[*]")
This returns a collection of Nodes and you can then use .length to see how many are returned. Make sure conditions is a child node of the root element. I am not sure, I think you do not specify the root node when accessing the record nodes.
