Java methods in coldfusion: invalid CFML construct

Question

I have the line:

<cfif isArray( this.filters[this.name] ) 
       AND this.filters[this.name].Contains(JavaCast("string",par.fval)) >

which is generating an 'Invalid CFML Construct: contains' error message.

Am I missing something or are the java methods not available when an array is created?

Just curious.. is ArrayFind/ArrayFindNoCase not available in your version? — Leigh

Hi Leigh, it is available but I didnt realize until a little later that function existed and in the meantime I already got zealous on using the contains method. — Magic Lasso

Well just watch out for data type differences. In case you are not already aware, contains() makes a distinction on data type (unlike CF array functions). Searching for "1.5" (string) will not yield the same results as val(1.5) (number) — Leigh

For me the error is a little more explicit:

Invalid CFML construct found on line 1 at column 71.

ColdFusion was looking at the following text:
Contains

And it's saying that because contains is a reserved-ish word in CFML, and something about the combo of that and the square brackets is fooling the parser into thinking there's a problem.

However this sort of thing should work:

<cfset proxy = this.filters[this.name]>
<cfif isArray( this.filters[this.name] )  AND proxy.Contains(JavaCast("string",par.fval)) >
</cfif>

NB: this is a vagary of ColdFusion... Railo does not have this problem. I'm gonna blog it & cross-reference here.

lol I really should have thrown more syntax at it. Keeping everything dynamic Im always running into this kind of stuff. This is good to know for the future. Thank you very much.
