toString null or undefined – Description
I can bet that each of you has at some point encountered with this issue. Especially when working on custom entities or customized built-in entities form.
What is the cause? Hmm, there is a couple of possible reasons.
Reasons
First of all – Microsoft fault 🙂 Some internal form scripts are executing to quickly not waiting for other script to load. Even though MS is fixing their TypeScript script these errors still occur.
Another one is a user fault. Badly designed form scripts can cause a lot of troubles to a developer.
The last one – 95% of all cases IMO – is a entity Ribbon which has been previously modified.
Solution
Please check the RibbonDiff section of entity and provide a value to …. tooltipText. I assume you will use RibbonWorkbench (or you are a masochist if you don’t) for that.
The safest option is to provide all labels for default language.
Hope it helps 🙂
