how to to check array Null value on coldfusion 7

[jiecoldfusion]

Hi,

How do you check the array elements empty or not.

for example, I have array[1] - array[10] , and from array[2] to array [10]
has some value, and there is no value in array[1]. How can I check it. Because
before I can check it using

if(array[1] eq "") (in coldfusion 5, it works)

but right now I am using coldfusion 7. It gives me an error about undefined
value. (java exception).

Can you tell me how to check?

Thank you,

I don't think you have any way in MX (both 6 & 7) to test for the array element
is empty or not.

<cfset foo = ArrayNew(1)>
<cfset foo[2] = "foo">
<cfif isarray(foo)><cfdump var="#foo#"></cfif>

Use the above code to dump what's in that array. It says "[undefined array
element]" for foo[1]. What I would suggest is initialize all the array elements
with "" i.e. foo[1] = "". Or else use a "try, catch" block as an workaround.

I know it's a nasty way of wrtting code. But what to do, there is no function
like "isEmpty" to verify the null elements. I hope many would have suggested
this to macromedia. I don't know why they haven't taken it up.

Thank you so much, try catch works
