The InfoTableFunctions.Union service is not working for us in 5.0. Below is some sample code.
var params1 = {
infoTableName : "InfoTable",
dataShapeName : "LWShareType"
};
// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(LWShareType)
var result1 = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params1);
result1.AddRow({"Name":"name1","Value":"value1"});
result1.AddRow({"Name":"name2","Value":"value2"});
result1.AddRow({"Name":"name3","Value":"value3"});
var params2 = {
infoTableName : "InfoTable",
dataShapeName : "LWShareType"
};
// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(LWShareType)
var result2 = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params2);
result2.AddRow({"Name":"name4","Value":"value4"});
result2.AddRow({"Name":"name5","Value":"value5"});
result2.AddRow({"Name":"name6","Value":"value6"});
var params = {
t2: result2 /* INFOTABLE /,<br> t1: result1/ INFOTABLE */
};
// result: INFOTABLE
var result = Resources["InfoTableFunctions"].Union(params);
