Hello,
When I change the backing bean openDataList to request scope, I got the exception when I click any header to sort.
javax.servlet.ServletException: Cannot get value for _expression_ '#{openDataList.data}'
If I set preserveDataModel=true or or both, I still got the exception. What is wrong?
Previously I used with dataTable, data conversion was done by JSF between String/Integer, String/BigDecimal. When I changed it to use for variable number of columns, I got error.
Cannot set value for _expression_ '#{backingBean.columnValue}' to a new value of type java.lang.String
In the backin
Yeah, that is definitely what's going on. Thanks a ton!

It's the validation method binding, not a validator.
To save you a trip, the signature is thus:

Since you have data associated with your many-to-many, you can simplify this
