Hi all,

This might be reaching, as it seems like something unique to my implementation, but has anyone else come across something like this:

I have this code powering a cascading dropdown column:


			relationshipList: "{C62FA8D5-CF36-47B2-92C1-ADAA40259012}",
			relationshipListParentColumn: "Company",
			relationshipListChildColumn: "Category",
			relationshipListSortColumn: "ID",
			parentColumn: "Nominators Company",
			childColumn: "Category",
			debug: true

The code is working perfectly, but the form itself gives a generic "An unexpected error has occurred" page when the user clicks 'OK' - it doesn't even run OOTB validation first.

If I comment out this code snippet, the form will submit perfectly. It should be noted that I am also running SPRedirectUserWithID from this library on the same page, and this too executes without issue...


any thoughts anyone?

This is caused by invalid data in the dropdown most likely. I have seen this posted before. This actually is the OOTB validation which is having a problem with the dropdown. I am not sure what data might be causing it to error, but I have found that if the dropdown contains items that are not correctly formatted or some special characters. Just something to look into.

Mosre often than bad data is that the relationships between the lists aren't set up properly with respect to the lookups.

I guess my brain is not fully awake this morning as that is a much better way of saying what I meant to say! That is what I meant by bad data!

Brilliant. Good job gents. Turned out I had set the child column as a choice field long ago, and did not think to change this to a Lookup when I introduced the filtering.

Is that a question or a statement, can you be more specific?

If you want to physically add a new choice to the list, you may be able to use the UpdateList operation to reconfigure the column. If you're just talking about populating a select element with choices you can use straight jQuery to push the options to the field and wouldn't need SPServices unless you were pulling those options from a list.
