I’m having another go at getting MyEclipse Reports to work with a scripted data source.

I’m getting an”Unhandled exception when executing script” error when I try to preview. (Stack trace below). My code at the moment is as trivial as I can get it, with only “open” and “fetch” filled in, as follows:

open:
totalrows = 3;

fetch:
if (currentrow >= totalrows) {
return(false);
}

var Field1 = “fred”;
var Field2 = “gomez”;
var Field3 = “foobar”;

row[“Field1”] = Field1;
row[“Field2”] = Field2;
row[“Field3”] = Field3;

currentrow = currentrow + 1;

return(true);

Here’s the error:

ReportDesign (id = 1):
+ There are errors evaluating script “if (currentrow >= totalrows) {

}

var Field1 = “fred”;
var Field2 = “gomez”;
var Field3 = “foobar”;

row[“Field2”] = Field2;
row[“Field3”] = Field3;

currentrow = currentrow + 1;

return(true);

cusdx,
You seem to be attempting to use the “row” variable without defining it. If you add “var row = new Object();” before you use the row array, I think it should work.
