Java snippet - DoubleCell/Java type double [] problem

Hello, I have a problem with node containing this column type:

ListCell (Collection of: ListCell (Collection of: DoubleCell))

It looks like this: 

[[-0.518, -1.431], [-1.431, -0.518]]

Next node is Java Snippet. In input, the only Java type option for this column is String, which is absolutely wrong as you can see:

ERROR     Java Snippet  Execute failed: java.lang.ClassCastException: java.lang.String cannot be cast to  [Ljava.lang.Object;

Is there any solution for this problem?

Thanks for help.

Hi jirinovo,

the JavaSnippet node can handle collections of doubles, etc. but not collections of collections.

We will change the type definitions in the JavaSnippet node in order to handle this more dynamically and be more flexible. However this will take some time, probably until summer 2015 latest.

Cheers, Kilian

Hi Kilian,

Are there any news on that topic? I encounter the same issue using Knime 11
