In my report i have three nested tables. and i am getting data from pojo.
Outermost table dataset is named ParentTable. I read this pojo in open script of this dataset like this,
var reportDto = reportContext.getAppContext().get("reportDto");
parentReportsItr = reportDto.iterator();
and in fetch method i set the fields with appropriate values along with the list of pojo which is meant to be passed to middle table like this,
if(parentReportsItr.hasNext()){
var parentReport = parentReportsItr.next();
row["ParentReportDto"] = parentReport.getReportList();
row["SubType1"] = parentReport.getSubType1Name();
return true;
}
return false;
Middle Table's Data set name is OuterTable, in this data set i created a parameter("parentReportParam") to read the outermost dataset row value and i set the binding of this parameter with data row value in binding tab of layout section.
and read that value of parameter(parentReportParam) in open method of outertable dataset script. like this,
reportItr = inputParams["parentReportParam"].iterator();
This is the issue i am unable to made successfull binding with the dataset row of outer most table and repeatedly getting the following exception.
