reference to a node element causes a form to crash

https://groups.google.com/d/topic/javarosa-developers/AxAdvTfuRwY/discussion

What steps will reproduce the problem?
1. using attached xform, fill-in the fields (name, kinship, age) in a loop
2. At the end of the loop, select "add another" to add another person.
3. You will be asked to fill-in the name. Enter one and/or swipe to next page 
and Collect crashes.

What is the expected output? What do you see instead?
Access the value stored in the node /d_bug/roster[1]/name. 

The xform works if there's only one node, if there's more than one node Collect 
crashes after you fill-in your name.

What version of the product are you using? On what operating system?
1.2 1012 on 2.3.7

Please provide any additional information below.
See attached xform and catlog

The expression that causes the failure is: "/d_bug/roster[1]/name".

If I take this out, the loop works fine.

It appears that most of the XPath functions are not supported in this version 
of JR.

I.e., last(), first(), position(), etc. are not available.

While these parse and validate, they do not actually filter anything, causing 
the full list to be passed through (why not an error?), which in turn causes 
the reported fault.

• Added labels: Collect

Fixed in 1.2 rev 1013 if you change the form to use position()=1

Attached is the revised form.
