Subject [jira] [Created] (OLINGO-1184) Expression Parser handles bound functions incorrectly following type filter

---------------------------------

             Summary: Expression Parser handles bound functions incorrectly following type
filter
                 Key: OLINGO-1184
                 URL: https://issues.apache.org/jira/browse/OLINGO-1184
             Project: Olingo
          Issue Type: Bug
          Components: odata4-server
    Affects Versions: (Java) V4 4.5.0
            Reporter: Philip Ho
         Attachments: cast-with-bound-function.patch, mock_data.png

When attempting to filter an entity set via a function that is bound to the subtype of a navigation
property's entity type, the expression parser is confused about which segment holds the bound
function's name and which type the function is bound to.

Example URl
/ESNavSrc?$filter=NavPropertyETNavTarget/Namespace1_Alias.ETBaseBF/Namespace1_Alias.BFETBaseBF()

!mock_data.png|thumbnail!

The issue is in parseMemberExpression, the wrong fully qualified name was being passed and
the last resource in this case differs from other cases where parseBoundFunction is called.
I've refactored parseBoundFunction's method signature to be more flexible so that in these
cases we can pass in the type filter type instead of the base type.

Patch file for fix with mock data and test:
[^cast-with-bound-function.patch]
Generated relative to 4.5.0 : 8a968923baa03235356feae73e72496890307647
