Advanced Compilation Error - perhaps in the HTML Sanitizer or in my code?

[Lillian at Ysight]

Hello.  After updating to the latest closure library, I get a RUN-Time error (not a compiler time error).  Screen shot of the chrome debugger is above.

I do use the sanitizer as 

var mySanitizer =

    new goog.html.sanitizer.HtmlSanitizer.Builder()

.withCustomNetworkRequestUrlPolicy(goog.html.SafeUrl.sanitize)// lose the id?

.allowCssStyles()

.allowFormTag()

.addOriginalTagNames() 

.withCustomTokenPolicy(goog.functions.identity) // so id= can be used and styles

.allowDataAttributes([ "data-id","data-name" ]) //data-* attributes are inert as per HTML5 specs

.build();

goog.exportSymbol ('toolbox.utils.mySanitizer', mySanitizer) ;

and later I use

areYouSureDialog.setSafeHtmlContent(toolbox.utils.mySanitizer.sanitize(htmlAreYouSure));

The full function that is returned by the advanced compilation is listed below.  Does anyone see the error in my code or the closure library.  The line the debugger complains about for the Type Error is in large font and highlighted.

 Thank you very much for your help.

function kj(a, b) {

    var c = document.createElement("span");

    if (!Pi || !b)

        return c;

    try {

        var d = document.createElement("template");

Please note:  this is a run-time error!  The compilation works correctly.  Thank you in advance.

Without seeing any uncompiled source code, it's very difficult to have any idea what could be going wrong.  Can you remove any extraneous lines of code (such that the error still persists) and post both the uncompiled and compiled versions?

Typically this sort of thing is caused by using a property unquoted that needed to be quoted, or by an inaccurate cast causing the compiler to think a variable is the wrong type.  But without seeing original code, it's hard to say.  Sometimes, in putting together a minimal example of the problem, you can even end up figuring out what's wrong yourself.

Hello,

Thank you for your response.

I have narrowed it down to the following lines of code.  I have never really “coded” a variable like this in an google-api-client export and clearly it does not work.  I have done it with function successfully

Would you happen to know how you “externalize” an object that has attributes that are functions for the good compilation?

Thank you,

Lillian

var mySanitizer =

    new goog.html.sanitizer.HtmlSanitizer.Builder()

.withCustomNetworkRequestUrlPolicy(goog.html.SafeUrl.sanitize)// lose the id?

.allowCssStyles()

.allowFormTag()

.addOriginalTagNames() 

.withCustomTokenPolicy(goog.functions.identity) // so id= can be used and styles

.allowDataAttributes([ "data-id","data-name" ]) //data-* attributes are inert as per HTML5 specs

.build();

goog.exportSymbol ('toolbox.utils.mySanitizer', mySanitizer) ;

goog.exportSymbol ('toolbox.utils.mySanitizer.sanitize', mySanitizer.sanitize) ;

signInDialog = new goog.ui.Dialog(null, USE_IFRAME);

signInDialog.setSafeHtmlContent(toolbox.utils.mySanitizer.sanitize(htmlLogin));  <—  problem line does not understand “sanitize” function - 

[Steve Hicks]

Ah, sanitize is an instance property, so exportSymbol won’t work: you need to use goog.exportProperty for properties.

goog.exportProperty(goog.html.sanitizer.HtmlSanitizer.prototype, 'sanitize', goog.html.sanitizer.HtmlSanitizer.prototype.sanitize);
