OVS with no input parameter

Hi,

I'm trying tu implement an Object Value Selector for one of my inputfields.

I use an RFC fonction module that gives a list of values that the OVS should use. I follow the tutorial on OVS but the difference is that my RFC function does not have input parameters, it only outputs a list.

The result is that when I am press the OVS button of my inputfields, I get the following error :

[code]java.util.NoSuchElementException

at java.util.TreeMap$EntryIterator.nextEntry(TreeMap.java:1024)[...]

[/code]

I do not do anything in the method applyInputValue because I do not have input parameters so I can't set them but this is probably causing the problem.

How can I correct this ?

Thanks,

Sylvain
