I'm a complete newbie and seem to have run into this trying to get a first free force.com site up.

http://boards.developerforce.com/t5/New-to-Cloud-Development/Deployment-failure/m-p/236207

Unfortunately I don't understand how to resolve it and move to first base  -I don't want to install the IDE and start all over again since I'm already drowning here.

HELP please!

Yes, this is a major problem for us still too.  I contacted our premier support and they put the MyProfilePageController.cls back in our production so that I could create a new Site.  Then I had to do a fresh deployment from our sandbox 10 minutes later, which then failed, so I had to go back to my ide and comment out the code in that class to deploy.

So, as we are heavy users of both Sites and sandbox development, now we have to:

1) re-deploy MyProfilePageController.cls everytime we want to create a Site

and / or

2) Comment out code and re-deploy MyProfilePageController.cls every time we want to deploy new custom classes/triggers/visualforce.

It's really awesome.

I work in a lot of different orgs that have this problem, so I usually use this version (slight modification) that at least doesn't fail tests:

/**
 * An apex class that keeps updates of a portal user in sync with its corresponding contact.
   Guest users are never able to access this page.
 */
public class MyProfilePageController {

    private User user;
    private boolean isEdit = false;
    
    public User getUser() {
        return user;
    }

    public MyProfilePageController() {
        user = [SELECT id, email, username, usertype, communitynickname, timezonesidkey, languagelocalekey, firstname, lastname, phone, title,
                street, city, country, postalcode, state, localesidkey, mobilephone, extension, fax, contact.email
                FROM User
                WHERE id = :UserInfo.getUserId()];
        // guest users should never be able to access this page
        if (user.usertype == 'GUEST') {
            throw new NoAccessException();
        }
    }
    
    public Boolean getIsEdit() {
        return isEdit;
    }
    
    public void edit() {
        isEdit=true;
    }    
    
    public void save() {
        if (user.contact != null) {              
            setContactFields(user.contact);
        }
        
        try {
            update user;
            if (user.contact != null) { 
                update user.contact;
            }
            isEdit=false;
        } catch(DmlException e) {
            ApexPages.addMessages(e);
        }
    }
    
    public PageReference changePassword() {
        return Page.ChangePassword;
    }
    
    public void cancel() {
        isEdit=false;
        user = [SELECT id, email, username, communitynickname, timezonesidkey, languagelocalekey, firstname, lastname, phone, title,
                street, city, country, postalcode, state, localesidkey, mobilephone, extension, fax, contact.email
                FROM User
                WHERE id = :UserInfo.getUserId()];
    }
    
    private void setContactFields(Contact c) {
        c.title = user.title;
        c.firstname = user.firstname;
        c.lastname = user.lastname;
        c.email = user.email;
        c.phone = user.phone;
        c.mobilephone = user.mobilephone;
        c.fax = user.fax;
        c.mailingstreet = user.street;
        c.mailingcity = user.city;
        c.mailingstate = user.state;
        c.mailingpostalcode = user.postalcode;
        c.mailingcountry = user.country;
    }

    static testMethod void testSave() {         
        // Modify the test to query for a portal user that exists in your org
        User existingPortalUser = [SELECT id, profileId, userRoleId FROM User WHERE ( UserRoleId <> null AND UserType='CustomerSuccess') or Id = :UserInfo.getUserId() LIMIT 1];
        
        System.assert(existingPortalUser != null, 'This test depends on an existing test portal user to run');
        
        String randFax = Math.rint(Math.random() * 1000) + '5551234';
        
        System.runAs(existingPortalUser) {
            MyProfilePageController controller = new MyProfilePageController();
            System.assertEquals(existingPortalUser.Id, controller.getUser().Id, 'Did not successfully load the current user');
            System.assert(controller.isEdit == false, 'isEdit should default to false');
            controller.edit();
            System.assert(controller.isEdit == true);
            
            controller.cancel();
            System.assert(controller.isEdit == false);
            
            controller.getUser().Fax = randFax;
            controller.save();
            System.assert(controller.isEdit == false);
        }
        
        // verify that the user and contact were updated
        existingPortalUser = [Select id, fax, Contact.Fax from User where id =: existingPortalUser.Id];
        System.assert(existingPortalUser.fax == randFax);
        //System.assert(existingPortalUser.Contact.fax == randFax);
    }

}

Sadly I can't even install the IDE on Win XP to resolve this problem:- http://boards.developerforce.com/t5/New-to-Cloud-Development/IDE-won-t-install-on-Win-XP/m-p/236677

Heapofcrap software :-(
