I'm working on a sample app for Facebook, using Flash Builder and Flex.
Now, I've got everything up and running - but there's one problem, specifically with the work history part.
When I try to display the user's work history..here's the code for logging in:
protected function login():void
{
FacebookDesktop.login(loginHandler, ["user_birthday", "user_work_history"]);
}
Here, loginHandler's a callback function, that then goes ahead and displays data about the user:
protected function loginHandler(success:Object,fail:Object):void
{
if (success){
currentState = "LoggedIn";
fname.text = success.user.name;
userImg.source=FacebookDesktop.getImageUrl(success.uid,"small");
birthdayLbl.text=success.user.birthday;
workLbl.text=success.user.work;
}
}
Now, the problem occurs with success.user.work - it ends up printing the following:
[object,Object],[object,Object],[object,Object],[object,Object]
Obviously, I'm doing something wrong..but I can't figure out what exactly it is. Would be grateful for some pointers!
Thanks!
Rudi.
The object contained in success.user.work is most likely an array of objects, each item representing a work period, so you'll have to treat it as such. Either use a list and a custom renderer for each item, or create a string by iterating over the array, and appending the fields that you're interested in.
To see what the individual objects contain, either use a breakpoint during debug and inspect them, or check to see if they're documented in the facebook development documentation.

I've written a program in C using ncurses and specially forms. I need that a particular field of my form moves as I'm filling the form. I tried move_field, but it doesn't work.
Here is how I wrote it :
if (typact==ADSD && rowc>rowg )
{
move_field(field[ietg],rowg=rowc,colg);
refresh();
}
I'm sure that the move_field is executed (I use xCode for debugging my program). I presume that refresh is not sufficient. I tried also placing move_field between unpost_form and post_form like this:
if (typact==ADSD && rowc>rowg /* && !field_status(field[ietg]) */ )
{ unpost_form(my_form);
move_field(field[ietg],rowg=rowc,colg);
post_form(my_form); refresh();
}
but it doesn't work once again. The form is erased and re-posted without the texts I have written and the field is always in the same place.
How could I use move_field?
The manual page says
The function move_field moves the given field (which must be disconnected) to a specified location on the screen.
You can disconnect a field by retrieving the current list of fields with form_fields (and its length using field_count), removing the field from that list and updating the list using set_form_fields.
When using move_field, you must also (temporarily) unpost the form with unpost_form. Otherwise, move_field returns E_POSTED (The form is already posted). After moving the field, use post_form to get the form-driver to work with the updated form.
The test/move_field.c file in ncurses sources provides an example of these calls.
I'm having trouble displaying the label of my components properly in tStatCatcher. I have renamed my components label but upon logging of tStatCatcher's origin field, the name is still the previous one.
E.g. Renamed my tDatabaseInput from MY_QUERY from tDatabaseInput1
tStatCatcher is still displaying tDatabaseInput1. It should be the new name MY_QUERY.
Anyone can provide assistance.
Thanks in advance
You can't delete the technical name of the component, it will always appear in logs as tComponent_1, to ensure unicity.
What you can do is adding MY_QUERY to the technical name, using __UNIQUE_NAME__
It will still not appear in your log, but you'll be able to see that MY_QUERY is linked to tComponent_1.
For example :
[]
I'm not sure if this is the best answer. But I'm sticking to this implementation for now unless someone shared a much better way.
I created a routine java class with a method that maps the from the tStatCatcher's row.origin to my hardcoded list of label names:
public static String mapToLabel(String uniqueName) {
switch(uniqueName) {
case "tDatabaseInput1":
return "MY_QUERY";
default:
return "--not mapped";
}
}
Then I called this method on my tMap's expression editor.
I override the record view, by creating in custom/modules/myModule/clients/base/views/record/record.js this file record.js. I want to get the value of a field for the current object and I use this.model.get('duration'), but I get nothing.The only field available is "id". How can I retrieve the values for others fileds?
When the record.js script is initially called, the model won't have fully loaded, so the only available field with be the id.
Your best bet is probably to override the _renderHtml function; by the the time the view is being rendered all the model details will have fully loaded:
_renderHtml: function() {
// custom code involving this.model.get('duration')
// call parent
app.view.View.prototype._renderHtml.call(this);
}
Note that you may find _renderHtml is called multiple times, sometines before the model is fully loaded. This is just a quirk of Sugar so it may be best to add a check in your code:
if (this.model.get('duration')) {
// custom code involving this.model.get('duration')
}
Dont forget that app.model.get('myfield') only delivers the right content (from this field) when your field is already displayed in detailview - else you will get "undefined"!
So you
Have to call the rest api (rest/v10/yourmodel/yourid) - than you
have all the values available
Display your fields (even you dont want to) to be able to use it in app.model.get('yourfield'), an alternative you could append your record.js (after rendering) with $('div [data-name="yourfield"]').hide();
I know this question is quite old already (but if someone else run into this he could find this useful).
I've been working on this for sometime now, and I keep running into a wall. I think I'm close, but I figured someone out here in the land of SO might have some deeper insight if not a better way of doing what I'm trying to do.
Basically lets look at this scenario. I have a logo w/ some text that can be set from a few different places. If we look at the setup here is what it looks like.
Hiearchy:
Homepage [has designPath]
- Child Microsite Page [has designPath]
- Logo Component
Logic Flow (in logo component):
if properties.get("logoText") {
use this
} else if currentStyle.get("logoTextFromStyle") {
use this
} else if parentStyle.get("logoTextFromGlobal") {
use this
} else {
be blank
}
My query is with how to get the "parentStyle" of this page. Looking at the docs here: http://dev.day.com/docs/en/cq/5-5/javadoc/com/day/cq/wcm/api/designer/Style.html
I've been able to come up with the fact that I can get a Style object from the "designer" object made available via defineObjects. This is defined with the other utility objects like "pageManager, resourceUtil, resource, currentPage, etc".
With that being said this doesn't seem to work.
//assuming we have getting homePage earlier and it is a valid cq Page resource
Resource homePageResource.slingRequest.getResourceResolver().getResource(homePage.getPath());
Style homePageStyle = designer.getStyle(homePageResource);
at this point homePageStyle is null. To do some more testing I i tried passing currentPage.getPath() instead of homePage.getPath(). I assumed this would give me the currentPage resource and would in end yield the currentStyle object. This also resulted in a null Style object. From this I think I can safely conclude I'm passing the incorrect resource type.
I attempted to load the the cq:designPath into the resource hoping to get a Designer resourceType but to no avail.
I am curious if anyone has run into this problem before. I apologize if I've gone into too much detail, but I wanted to lay out the "why" to my question as well, just in case there was a better way overall of accomplishing this.
I've figured out how to return the style. Here is the rundown of what I did.
//get your page object
Page targetPage = pageManager.getPage("/path/to/target");
//get the Design object of the target page
Design homePageDesign = designer.getDesign(homePage);
//extract the style from the design using the design path
Style homePageStyle = homePageDesign.getStyle(homePageDesign.getPath());
it's very interesting the definition of "getStyle" is a little different from the designer.getStyle vs a Design.getStyle. designer.getStyle asks for a resource whereas Design.getStyle will take the path to a Design "cell" and return the appropriate Style.
I did some testing and it looks like it does work with inherited Styles/Designs. So if my cq:designPath is set at level 1 and I look up a page on at level 2 they will return the Design/Style at the cq:designPath set at level 1.
I hope this helps someone else down the way.
I tried this approach but was not getting the Styles in the Style object.
When we do this:
Design homePageDesign = designer.getDesign(homePage);
In this Design object we get the path till the project node i.e etc/design/myproject
After this if we try to extract the Style from the design path we do not get it.
However I implemented it in a different way.
In the design object, we also get the complete JSON of designs for(etc/design/myproject).
Get the sling:resourceType of the target page and get the value after last index of "/".
Check if this JSON contains the last value. If it contains, you can get your styles, i.e. image, etc.
I've been looking on forums for 2 days now and can't find a good answer so I'll just post it.
I appear to be having a problem posting JSON back to the controller to save. The JSON should map to model view but it keeps getting default(constructor)values rather then the values from the POST.
We have a series of JS widgets that contain a data field with json in them. We do all our data manipulation in these widget objects on the client side. When a user wants to save we grab the data we need from the widgets involved and we put it into another JSON object that matches a ViewModel and POST that back to the server.
For example:
$("#Save").click(function () {
if (itemDetails.preparedForSubmit() && itemConnections.preparedForSubmit()) {
itemComposite.data.Details = itemDetails.data;
itemComposite.data.Connections= itemConnections.data;
$.post(MYURL, itemComposite.data);
} else {
alert("failed to save");
}
});
The preparedForSubmit() method simple does stuff like any validation checks or last minute formatting you might need to do client side.
The itemDetails widgets data matches a ViewModel.
The itemConnections widgets data matches a collection of ViewModels.
The Controller looks like this:
[HttpPost]
virtual public JsonResult SaveItemDetailsComposite(ItemComposite inItemData)
{
if (ModelState.IsValid)
{
try
{
_Mapper.Save(itemComposite.Details , itemComposite.Connections);
return Json(true);
}
catch (Exception ex)
{
_log.Error("Exception " + ex.InnerException.Message);
throw;
}
}
return Json(SiteMasterUtilities.CreateValidationErrorResponse(ModelState));
}
The ItemComposite Class is a simple View Model that contains a single itemDetails object and a collection of itemConnections. When it returns data to here it is just getting the default data as if it got a new ItemComposite rather than converting the POST data.
in Firebug I see the data is posted. Although it looks weird not automatically formatted in firebug.
Are you saying that itemComposite.data is formatted as a JSON object? If so, I'm pretty sure you're going to have to de-serialize it before you can cast it to your object. Something like:
ItemComposite ic = jsSerializer.Deserialize<ItemComposite>(this.HttpContext.Request.Params[0]);
You may want to look into a framework like JSON.NET to ensure that your data is being serialized properly when it gets supplied to your Action.
JSON.NET seems like it's one of the main stream frameworks: http://json.codeplex.com/releases/view/43775
Hope this helps.

You could also use the JSON Serializer in WCF: http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer.aspx
SO wouldn't let me put both links in one answer, sorry for the split answer.
Thanks everyone. I think I have solved my problem and I'm pretty sure that I had four issues. For the most part I followed thatSteveguys's suggestion and read more on this article: http://haacked.com/archive/2010/04/15/sending-json-to-an-asp-net-mvc-action-method-argument.aspx
Using jQuery's post() method and specifying json as the type didn't seem to actually send it as json. By using the ajax() method and specifying json it sent it as json.
The JSON.serialize() method was also need to cleanly send over the json.
Also my ViewModel design was a big problem. We are using the MS code analytic build junk and it didn't want me having a setter for my collections in the ViewModel. So me being from a java/hibernate world, thought it didn't need them to bind and it would just come in as a serialized object magically. Once I just suppressed the error and reset up my setters. I am getting the collections now in my controller.
I believe using the MVC2 Future's Value Providers are doing something but it still doesn't convert json dates robustly, So I am still investigating the best way to do that.
I hope my issues help out others.
UPDATE: using this method to update collections of data appears to be super slow. A collection with 200 entries in it and 8 fields per entry takes 3 minutes to get to the controller. Just 1 or 2 entries take very little time. The only thing I know of that is happening between here is data binding to the model view. I don't know if MVC2 provides a easy way to send this much data and bind it.
