Undefined variable or classname snpRef (when executing Java within a KM)

Question

Hi there,
I'm looking into ODI, specifically customizing scripts using java functions and have hit a bit of a problem.
Does the following error ring any bells?
Attempt to resolve method: getobjectname() on undefined variable or class name: snpref
I find it quite weird and strange that it cannot find snpref?
The script is below - as you can see, I'm just having a play around
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = odiRef.getFrom(); %>+
+<%sTestString = sTestString.toLowerCase();%>+
+<%out.print("/*"+sTestString+"*/");%>+
As you can see, I have no clue where snpref is being called from. It may be an internal translation of odiRef but I thought snpRef has been deprecated!? What's also weird is that without the last or penultimate line, everything works fine?
For example, this works:
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = odiRef.getFrom(); %>+
+<%out.print("/*"+sTestString+"*/");%>+
it gives:
drop table ODI_TESTING."C$_0SmalldatetimeTable"
+/*Testing.dbo.SmalldatetimeTable as SMALLDATETIMETABLE*/+
Also this works:
drop table <%=odiRef.getTable("L", "COLL_NAME", "A")%>
+<%String sTestString = "TeSt"; %>+
+<%sTestString = sTestString.toLowerCase(); %>+
+<%out.print("/*"+sTestString+"*/");%>+
outputting (as totally expected):
drop table ODI_TESTING."C$_0SmalldatetimeTable"
+/*test*/+
What gives? I know this is a bit theoretical but I'd really love to know what's causing it to break so spectacularly? Could it be some sort of misconfiguration?
Here's the stack trace:

Answer 1

Okay here is the solution.
I tried 100s of ways but it didnt work. So the alternative is create one more step in your KM with jython technology. Below code will print it in lowercase.
sTestString= '<%=sTestString%>'
raise (sTestString.lower())
Note: Click on ignore error. So that the flow will move on.
