ignored cell, invalid rule

Description of problem:
If you don't fill a value into a cell, that fact pattern is ignored in the source of that row. This doesn't really make sense and creates problems once you try to update that fact in an action column.

As you can see in the screenshot, I have a Fact [f], field [==] condition column and a f, field action column updating the field on the fact from the condition column. I have one row with only the action column cell filled in.

The source code then shows this:
1. | //from row number: 1
2. | rule "Row 1 gdt"
3. |     dialect "mvel"
4. |     when
5. |     then
6. |         f.setField( "aaa" );
7. | end

As you can see, this creates an invalid rule.

This happens for any empty cell, not just those in condition columns. 

The only understandable occurrence of this is for the attribute columns, where e.g. salience without a value would again create an invalid rule.
