#2676 Doc Value Workflow can't Set Variable for ID column

[KittiU]

If the set variable is in the column that Reference Type is Numeric, the MWFActivity.setVariable(...) is working OK.
But if the column is ID column, i.e., Table, Table direct, it will fail. This is because there is no checking for ID, and it parse as object instead of integer.

Step to Error

1. Setup a Document Value Workflow, make it to set value into any column with type Table or Table Direct.
- Document Value for C_Invoice with condition Updated=Created, set column C_DocTypeTarget_ID to value 118 (Credit Memo)
2. New Invoice Document, save it. Nothing updated in the Target DocType.
