Problems with more than four datasets

[annakrebs]

If more than four datasets are selected, the following error message appears:

"1: Space required after the Public Identifier 2: SystemLiteral " or ' expected 3: SYSTEM or PUBLIC, the URI is missing 4: Opening and ending tag mismatch: hr line 9 and body 5: Opening and ending tag mismatch: body line 4 and html 6: Premature end of data in tag html line 2"

e.g.: worldbank:SE.XPD.PRIM.PC.ZS,worldbank:SE.XPD.SECO.PC.ZS,worldbank:SE.XPD.TERT.PC.ZS,transparency:CPI2009,worldbank:SL.TLF.TOTL.FE.IN/AU,FR,IT,CH,US/2009

Already debugged problem, but wasn't able to resolve it. Error occurs at SPARQL package in sparql.R -> r doesn't get any value. The query (q) contains the right query value.

Which dataset combinations did you try?

Are you certain that it comes from the SPARQL package for R? Because you also told me that 4 datasets worked at one point but not 5. Moreover, if the query itself is tested directly from inside R (i.e., skipping Shiny stuff), it worked.

I tried: worldbank:SE.XPD.PRIM.PC.ZS,worldbank:SE.XPD.SECO.PC.ZS,worldbank:SE.XPD.TERT.PC.ZS/AU,FR,IT,SE,CH,US/2009

No, I'm not certain. But if I debug like this:

q <- sparqlQueryStringGroupedBarPlot(dataset, refArea, refPeriod) 
cat(paste0("q: ", q), file=stderr()) 
cat(paste0("sparqlEndpoints$stats : ", sparqlEndpoints$stats), file=stderr())

r <- SPARQL(sparqlEndpoints$stats, q)
cat(paste0("r: ", r), file=stderr())
cat(paste0("r$results: ", r$results), file=stderr())

I get a working query for "q" and for "sparqlEndpoints$stats" the value "http://localhost.stats.270a.info/sparql"

I don't get any values for "r" and "r$results", just the error message: Error : 1: Space required after the Public Identifier 2: SystemLiteral " or ' expected 3: SYSTEM or PUBLIC, the URI is missing 4: Opening and ending tag mismatch: hr line 9 and body 5: Opening and ending tag mismatch: body line 4 and html 6: Premature end of data in tag html line 2
