Hi, we are trying to do something like this in a decision table
we need to be able to create a condition like the below in a decision table
condition column. Perhaps one way this can be done is for user to be able to
select mutiple states from a dropdown list of states and then apply the
operator " is one of " on those selections.
State is one of {"AZ","CA","NV"}
Please let me know if this can be done .
Thank you all in advance.

some additional info on this.
when I try to use literal as the Calculation Type, I get an operator choice
of " is contained in the a (comma separated )list. This will let me select
only one of the values entered in the dropdown List.
when I do ViewSource , I see the above being converted as
yearOfOccurence in ("2010")
I want to be able to select more than one of those in the list .
evn though not as a dropdown, I tried to see if the below would work.
I tried to use predicate as the calculation Type and enter the expression as
follows:
yearOfOccurence in {"2010","2011"}.
This compiles fine, but throws an error when running the test scenario.
I tried yearOfOccurence in ("2010","2011")
This throws error at compile time.

The easiest way to do this is to use regular expressions with matches
Eg
state matches "AZ|CA|NV"
if you don't care about the case then use "(?i)AZ|CA|NV"
You can find details of regex here
http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html
There are also the "in" and memberof keywords which can do similar operations
but regex are probably easier.

while using the regular expression in a predicate is our last option, we
would like to do it through a dropdown list in a Decision Table column if
possible.
I am trying something like this.
when creating condition column, if I choose literal type and choose a filed
type such as amount , one of the operators is " is contained in the a
(comma....) List ".This translates to the in operator eventually.
By making the ListBox as multiselect through the constructor, I am able to
do a multi select in the List, but after I click the Ok button, it still
populates the last selected value in the dropdown.It looks like the Record r
can take only 1 value.
Button ok = new Button( constants.OK() );
ok.addClickListener( new ClickListener() {
public void onClick(Widget wg) {
for ( int i=0 ;i<drop.getItemCount();i++){
if(drop.isItemSelected(i)){
r.set( dataIdx,
drop.getValue( i) );
}
}
w.destroy();
}

I got it to work by appending the values and then setting the record to
appended string
r=value1+","+value2+","+value3
