             Summary: Lambda bound variable function parameters not being 
parsed by ParserHelper
                 Key: OLINGO-1334
                 URL: https://issues.apache.org/jira/browse/OLINGO-1334
             Project: Olingo
          Issue Type: Question
    Affects Versions: (Java) V4 4.5.0
            Reporter: Mike H


When using a lambda bound variable inside a function parameter, ParserHelper 
fails to include the lambda context within the ExpressionParser.  This results 
in a failed parsing of the URL.  

Line 197: 
https://github.com/apache/olingo-odata4/blob/4.5.0/lib/server-core/src/main/java/org/apache/olingo/server/core/uri/parser/ParserHelper.java#L197

For example:

/odata/ENTITY_SET?$filter=NAV_PROP/any(b:b/NEXT_NAV_PROP/any(bf:(namespace.CustomFunction(property=bf/PropertyName)
 ne 2))

We are unable to use the lambda property PropertyName from the lambda bound 
context variable 'bf'

Could we get some guidance on if we are approaching this incorrectly? Or if 
there is an issue with the olingo parsing?
