G'day
Consider this code:
<cfset a = arrayNew(1)>
<cfset a[1] = "tahi">
<cfset a[2] = "rua">
<cfset a[3] = "toru">
<cfset a[4] = "wha">
<cfset b = f(a)>
<cffunction name="f" returntype="boolean">
<cfargument name="a" type="array" required="true">
<cfreturn false>
</cffunction>
It works fine. It doesn't do anything, but it works. This is a
dramatically simplified repro case, needless to say.
Now: comment-out any of the first three array element assignments. Re-
run code.
I get this error:
BlueDragon Internal Server Error

I get a similar error, as it happens, on BD.NET:
java.lang.NullPointerException: Object reference not set to an
instance of an object.
at com.naryx.tagfusion.cfm.engine.cfArrayData.copy()
at
com.naryx.tagfusion.expression.compile.CFFunctionExpression.evaluateArgument(CFContext
_context, CFExpression _argExp, Boolean cfcMethod)
at
com.naryx.tagfusion.expression.compile.CFFunctionExpression.processUDFArguments(CFContext
_context, userDefinedFunction _function)
Note that making the argument type=any or not specifying a type at all
does not help.
Needless to say, an array with missing elements should still work as
an array, yes?
Shall I raise this as a bug?
I guess I could google the answer for this, but does anyone - offhand
- know if there is a publicly accessible bug tracker for BD.NET?
Cheers.
