I tried your .lca file. You are trying to maintain history in a table. thats good. As i have already told you, i have got the solution. i.e, I'm able to get the history by using some process level variables and some hardcoded text. But the problem is different.
The requirement is to have a list box for the history. Each statement has to be displayed in separate lines (not wraped). I dont know how to make use of list box for this dynamic behaviour. So we are using a text box. The problem is there is no object like text area. If we select Allow Multiple Rows checkbox, the lines gets wrapped when it hits the boundary. If i uncheck it, we cannot vertically scroll to view the entire text.
So do you have any method where in which i can bind a dynamic list box instead of a text box (The problem is we dont know how exactly history grows based on the iteration) OR to use text box object as a text area.
