Hi,
I'm trying to use global variables in a report and I don't seem to be
having any luck. I tried to follow the examples but I'm clearly doing
something wrong and I'm not sure what.
What I'm trying to do is create a hashmap of this things I want on
startup, from the parameters.
In the initialize event of the report:
importPackage(Packages.java.util);
configMap = new HashMap();
configMap.put("Queries" ,params["Queries"]);
configMap.put("Interval",params["Interval"]);
reportContext.setPersistentGlobalVariable("configMap", configMap);
Then in the open even on my scripted data source:
MultiTypeTTSQueryClass = new Packages.MyQuery();
returnvals = MyQueryClass.doQuery(params["Queries"],params["Interval"]);
configMap = reportContext.getPersistentGlobalVariable("configMap");
num_of_cols = MyQueryClass.getNumOfTypes(params["Queries"]);
type_names = MyQueryClass.parseTypes(params["Queries"]); // returns array
configMap.put("NumOfCols", num_of_cols);
configMap.put("TypeNames", type_names);
totalrows = returnvals.size();
currentrow = 0;
Then in beforeGeneration( chart, context ) of my chart:
seriesCount = 0;
legendCount = 0;
configMap = reportContext.getPersistentGlobalVariable("configMap");
ccolnames = configMap.get("TypeNames");
I then try to access the NumOfCols in my configMap hashmap
in beforeDrawLegendEntry(label,context)
As a test:
label.getCaption().setValue(configMap.get["NumOfCols"]);
and it doesn't seem to work. Anyone know what I'm doing wrong?

..Do I even need to use persistant variables ?

What error are you getting?
If you use your scripted ds in a table do you get any results?
What does this return?
configMap = reportContext.getPersistentGlobalVariable("configMap");
num_of_cols = MyQueryClass.getNumOfTypes(params["Queries"]);
type_names = MyQueryClass.parseTypes(params["Queries"]); // returns array
