If a lookup component in workflow like 'Query List' etc is having a value with apostrophe, the workflow is getting terminated:
For example:
If in the configuration below if {Variable:Brand} is having a value like xyz's (apostrophe inside) then the workflow is terminating throwing the error like substringof('xyz's',Brand/Title)" is not valid...
I have sorted it with a trick but not to an extreme satisfaction. I am not sure whether it's a bug or not but it seems a bug to me in NINTEX.
Let me know if you have any information about this.
