Passing parameter to scripted data source

sesker

Help!

I have integrated Birt into our application, but the problem is I can't seem to understand how to pass parameters to a scripted datasource.

I have the following code in the report execute (the engine load and starts fine):

task = engine.createRunAndRenderTanks(...);

Map<String,Object> parameters = new HashMap<String, Object>();
parameters.put("guid", trendWidget.getTrendId());
parameters.put("start", start);
parameters.put("end", end);
task.setParameterValues(parameters);
task.validateParameters();

...

in my scripted data source, I thought I could do the following:

var guid = params["guid"]
var startDate = params["start"]
var endDate = params["end"]

data = trendWidget.getReportData(guid, start, end);

...but I get an exception that start/end etc is not defined (A reference error).

I have tried:

var trendWidget = ...get my java class.

var guid = params["guid"].value
var startDate = params["start"].value
var endDate = params["end"].value

data = trendWidget.getReportData(guid, start, end);

...save result.

I even created input parameters in the properties of the data source to match...nothing I do seems to work.

What am I doing wrong? I just want to pass three arguments to the script engine to in turn pass back to my java object...

An alternate would be

reportContext.setPersistentGlobalVariable("guid", trendWidget.getTrendId());...


and use get to getPersistentGlobalVariable() the corresponding value.
