Description shreyder 2008-12-27 20:18:28 UTC 
The navigator does not recognize fields of an object, which are declared via the object's prototype in JavaScript source
files. However, it does recognize functions, which are declared via the object's prototype.

Example:

function AnObject() {
    this.fieldA = "fieldA";
    this.functionA = function() {return "functionA"};
}

AnObject.prototype.fieldB = "fieldB";

AnObject.prototype.functionB = function() {return "functionB"};

The navigator will list the constructor, fieldA, functionA and functionB, but not fieldB.

The same problem applies to code completion. Fields declared via the object's prototype are not visible.
Comment 2 Marek Fukala 2009-03-09 17:45:55 UTC 
A bug in JsAnalyzer.AnalysisResult.visit(Node) - the prototyped fields are not supported.
A piece of the AST with the prototyped field follows:

 133:EXPR_RESULT[155,208]<655b5671>
        35:SETPROP[155,208]<8cd9095>
            33:GETPROP[155,164]<1f2346b7>
                39:NAME("AnObject")[146,154]<4072dd9>
                41:STRING("prototype")[155,164]<5cea9004>
            41:STRING("functionB")[165,174]<3a543470>
            108:FUNCTION[177,208]<4dd5e29d>
                128:BLOCK[188,207]<6ee4b24e>
                    4:RETURN[189,207]<103bbd00>
                        41:STRING("functionB")[196,207]<295c7163>
Comment 3 Marek Fukala 2009-03-09 17:50:26 UTC 
Wrong example :-(. Here is the correct part:

 133:EXPR_RESULT[116,143]<2bb7e2f7>
        35:SETPROP[116,143]<4b317e13>
            33:GETPROP[116,125]<7cef8743>
                39:NAME("AnObject")[107,115]<350f1a7>
                41:STRING("prototype")[116,125]<54c17718>
            41:STRING("fieldB")[126,132]<73ae56bc>
            41:STRING("fieldB")[135,143]<7cc2fbf>
