scripted data source and column types - weirdness [message #134483]

Using BIRT 2.0 and Eclipse 3.1.2...

Ok, so I have a test class that returns a Float object from a function
(the function adds .1 to a local variable at each call and returns the
value of that variable for each iteration). If I define the column type
to also be Float, I get no data. If I define it as a String and I see
the data. And, JavaScript being loosely-typed, allows me to do
arithmetic on the Float in my script.

I would be happy to send source for those interested. I just hope this
saves someone else the 2+ hours it took me to trace down why I wasn't
seeing the values I was expecting in BIRT. I also assume that this is a bug?

You can leave it as Float, but as part of your loading of the field in the
row, you need to append an empty String to end up w/a String:

row["aField"] = aFloat + "";

This type of scripting would for your data set's "fetch" event.
