I’m just upgrading a project from version 7.9.12 to 7.9.14 and I’m facing the following 2 problems: 1. one page is populated with a **Template repeater**. Inside each single template variables are assigned to components through **Indirect addressing**. 7.9.12 is running without problems, whereas 7.9.14 raises the following exception whenever I enter the page: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/9/96b901f6913e43dc7b8667ab7e200bde00c921cf.png) one exception for each item in the repeater. 2. one page has a **Template canvas**. Each template background in the template canvas is colored based on an **Expression binding** such as ```auto tag(concat("PLC2SCADA/bits/RCAE_",{tplRCAE.sourceID},"1_Alarm")) ``` `sourceID` is a _Custom property_ which is passed to the template canvas as follows ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/a/aa535fd13bf6e9b849ab96ccc0403595ac87c388.png) Again: 7.9.12 is working as expected, whereas 7.9.14 is raising the following exception: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/3/313a04ed2d24dc0583817dfe836872154d29ca5d.png) Any suggestion? Thanks in advance, regards ---

Thanks jpark for pointing me to your post: it seems you incurred just my same issue. I think I’ll have to stay with 7.9.12 then. ---
