Interop with Java libs is way harder than it should be. Consider this real-world example of using the ElasticSearch Java API. (docs:

QueryBuilder qb = rangeQuery("age")   

If you create an instance of Elastic's rangeQuery, you can not call the gte method from ColdFusion at all. You get an error:

Invalid CFML construct found on line 12 at column 10.

ColdFusion was looking at the following text:








This is not an issue with parsing *gte* but a problem with recursive chaining. I just created a sample code snippet with *gte()* function and verified that the following code works: {code:java} WriteOutput(sample.gte(5)); {code} But the one having multiple dotted references fails eg: {code:java} WriteOutput(sample.gte(5).lte(15)); {code}

You sure yer looking at the same code, Ashudeep? The error reported in the ticket is a *compile* error. Having a problem multiple chained methods would be a runtime issue, would it not?

Yeah i know this is an issue with chaining kind of syntax in our parser.This will be a problem with any reserved keywords being used at the second and subsequent levels during function chaining and we are going to fix it.
