Hmm. I don't know of a way to make Struts 2 give back 2-D array properties in the auto-magical way that it will do 1-D arrays (doesn't mean there's not one: I keep finding out that a lot of things I want to do can be done by magic if you know the correct XML incantation) but perhaps you could sidestep this with JSON? I'm not particularly familiar with AJAX stuff, but my understanding is that JSON can encode any arbitrary object possible in JavaScript. That could potentially entail a large number of changes, though...
Or, another JavaScript solution, one that doesn't entail switching to any kind of AJAX, would be to have a script that concatenates all of one row's values into a single string, and then have a single-dimensional array property. Sort of wasteful in that processing time is spent composing and then parsing back to the original state, but I think it would serve your purpose.

Is it possible to get back 2D arrays from a form? I want to be able to have a table with some number of rows. Each row has a 'grouping' field which the user can enter a number in. Each row will also have a dynamic 'foo' column which will have a button to add additional 'foo' values. Some javascript will drop in new 'foo' textfields on a given row whenever that row's button is clicked. I want to be able to collect an int[] grouping array, which is straight forward. Iterating over a collection to create textfields will let me get an int[] in my action which will be the list of groupings indexed by row (so grouping[0] yields the entered value for the first row, grouping[3] yields the entered value for the fourth row, etc.) I also want to be able to collect an int[][] foo array. This should be an int[] array of foo values indexed by row. This is less straightforward and I'm not sure how to approach this. Are there any sorts of similar examples to this floating around? -- This message may contain confidential, proprietary, or legally privileged information.
