Steps to reproduce:

1. Install Zabbix 2.0.6.
2. Please have a look at the screenshot I have attached for the configuration
3. Create an item with the Zabbix agent active. 
4. Create a trigger based on that.
5. Then the trigger says "No update so far. Trigger just got updated". This remains like that.

Documentation is very poor. It doesn't have any examples. No useful data is found online.

Images Attachment:

1. Item Configuration
2. Trigger Configuration
3. Log file
4. Item Status
5. Trigger Status

Please help me out here!!!
