Thank You, Jason, problem solved :) Anyway, I believed the "autheticate" attribute of tag "gm:page" served for transferring the authentication of the browser to the gm application. Just like when logged into Google Reader and opening Gmail in another tab of the browser, You are automatically signed into Gmail, too. If it turns real in the future, that will be fun!

As far as I can tell, your authenticate() function is never executed, which probably explains why I can't see the authenticated content. To fix this, you can amend your onload() function as follows:

function onLoad() { if (google.accounts.user.checkLogin(authenticationURL)) { google.gdata.client.init(); myService = new google.gdata.calendar.CalendarService('Google- GData_Calendar_Mash-1.0'); ... } else { authenticate(); } };

Unfortunately, you cannot use the account credentials provided during application sign-in to authenticate to a Google data service, but I'll go ahead and file a feature request.

Happy mashing! - Jason

Hi Jason, Your question makes me beleive that it is the authenticated content (a table with calendar entry data) that is missing. So I assume I handle the token fetching incorrectly. My FireFox has got a valid token, that is why it is the only session showing the authenticated contents, too. In fact, I would like to use the GME login to fetch the token, too. Is it possible at all? When logging into GME, I use the same account that I refer to when fetching the token, right?

Hi Ádám. I see the same page across all three browsers: a green header ("The latest entries of calendars shared with You") along the top and a gm:calendar and gm:map display below it. Are you seeing anything different? What are you expecting to see?

Hi Jason, After some break I am working on my mashup again. Now I got the basics work, meaning I can access data, and the UI operates. Not that surprising, since it all comes from your demo. Although the functions are hardly touched, I am building a different logic with them. According to your recommendation, now I work with FireFox and FireBug. The result is a mashup that seems to be OK in FireFox, but not in IE6 or Safari for Win. In these last browsers the authenticated content simply does not appear. Would You pls have a look at it?http://ppfinder.googlemashups.com/ Thanks in advance

Hi Ádám. Sorry, this was my fault; google.gdata.Person.getName() returns a google.gdata.Name object. This object provides a getValue() method which returns a JavaScript string.

So, taking my code from earlier:

var authors = eventEntry.getAuthors(); var authorName = null;

if (authors.length > 0) { authorName = authors[0].getName().getValue();

}

... if (authorName) { new GPath('gmd:author').setValue(newEntry, authorName);

}

Two quick notes: 1. Currently, Safari 3 is not officially supported. Please use a supported browser such as Firefox 1.5+ or IE 6.0+. 2. Firebug is the best tool I know for JavaScript debugging. I found this particular error by setting a breakpoint just after initializing author. Firebug showed that author was an object instead of a string. I then used the JavaScript client library documentation to find the correct method to use.

http://code.google.com/apis/gdata/jsdoc/1.1/index.html

I hope this helps. Please let me know if you continue to run into issues

Hi Jason, Unfortunately, the same error message comes again: GPath.setValue(): Value set should be of type string. Is there any tool to get more info about javascript errors? I've tried Firefox's Javascript debugger, but it delivers the very same error message. Anyway, I've shared my Calendar with You, have a look at the

feed if

You like...

Ah, I see. More than likely, you're seeing this error because your author variable evaluates to null, either because the entry doesn't have an author associated with it or the author in question doesn't have an initialized name. See if this slight change suppresses the error:

var authors = eventEntry.getAuthors(); var authorName = null;

if (authors.length > 0) { authorName = authors[0].getName(); } ... if (authorName) { new GPath('gmd:author').setValue(newEntry, authorName); }

Hi Jason, Thanks. Strange, but the browser (IE6) reports the same

error:

"Line

string." Unfortunately, at the specified line there's

nothing to

do

with setValue.... I tried to coplete the setValue with .getValueString(), but it didn't work either. I haven't modified the "create new entry" block, neither its template, because I plan to remove this parts from my mashup. So I

Hi Ádám. The google.gdata.Entry class' getAuthors() method returns an array of google.gdata.Person objects. The class

specification

is

located here:

http://code.google.com/apis/gdata/jsdoc/1.1/google/gdata/Person.html

As you can see, this specification does not provide a getValueString() method. It does, however, provide getName():

var author = eventEntry.getAuthors()[0].getName(); ... new GPath('gmd:author').setValue(newEntry, author);

Please let me know if this works.

Hi All, Having slightly modified Jason's demo mashup, l have

Hi Adam. Since atom:author is managed by GME's

server-side

services,

it is not exposed in fetched feeds; this explains why

it

is not

appearing. I haven't tried this myself, but you may be able to extract an event's author using the getAuthors() method of the google.gdata.Entry class.

http://code.google.com/apis/gdata/jsdoc/1.1/google/gdata/Entry.html#g.

..

You could then copy this value into a custom GME

element (

e.g.

gmd:author) and display it using your textarea

control.

Please let me

know if this works for you.

Hi, I am usinghttp://demo-

own mashup, and I faced some difficulties when reaching the elements of the calendar feed. It is the lines 374..376 of the code in GME.

While

Jason's <td

expression

operates, the <td><gm:text

does not. I have

tried all the methods mentioned athttp://www.w3schools.com/xpath/xpath_syntax.asp, including ".author/name", and "atom:author/name"

I also could not reach the "gd:where@valueString

data element. On the

other hand, "title" can be fetched succesfully. Is there any trick that makes it work?

Hi Reto. I have some good news for you:

1) As of last week's release, all caches,

Google

Spreadsheets and Google Calendar, now expire

after

10 minutes --

much

better than once or twice a day. :) This

greatly

increases the

utility

of applications that use Google Spreadsheets,

store.

2) Styles for certain tags (including gm:link

gm:image) have

been

adjusted so that they now more closely match

their

HTML analogues,

meaning that they are now displayed as inline elements rather than block.

Enjoy!
