is_public does not work

[diesan100]

There is a property called like the title of this issue which does not save and... I don´t know what is it for... :)

[hubrajesh]

This property is used to check if user allowed to create/edit public event/content in a space or not.
If user is not allowed to created public content in a space and tries to do so then it will fail.
A quick fix for this -
edit file : /protected/modules/calendar/models/CalendarEntry.php

public function rules()
    {
        return array(
            array('title, start_time, end_time, all_day', 'required'),
            ...
            array('is_public', 'checkVisibility'), //add this array to fix issue
            array('all_day, recur, recur_type, recur_interval', 'numerical', 'integerOnly' => true),
            ...
        );
    }

and add a function for this rule to work in same class

    /**
     * Checks if current user can create public event
     * 
     */
    public function checkVisibility()
    {
       if (get_class($this->content->container) == 'Space') {
            if (!$this->content->container->canShare() && $this->is_public == 1) {
                $this->addError('is_public', Yii::t('base', 'You cannot create public visible content for this  space!'));
            }
        }
    }

There is other way too but will require editing 2 files controller and view file.
You can pass content model ( 'content' => $calendarEntry->content) to edit.php (view file) and then create input field for content->visibility instead of is_public.
In that case is_public will not be needed and validation error message will be acquired directly from content model class.
Better use quick fix for now and wait for proper fix by developers ! :)
