prevent repeating values in table - jasper-reports

Question

I have several subDatasets, most of the results I use with Charts and this (working) part:
<pieDataset>
<dataset incrementType="Group" incrementGroup="group_2113924770">
<datasetRun subDataset="data_2113924770" uuid="724d6473-dd5d-41c4-af6e-4c5b1d995416">
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]>
</connectionExpression>
</datasetRun>
</dataset>
</pieDataset>
The SubDataset definitions looks like this:
<subDataset name="data_2113924770" uuid="4a29c5a4-cd0a-4078-8b88-6699c60cbe5e">
<queryString language="MongoDbQuery">
<![CDATA[{ collectionName: 'xxx',
findQuery : { xxx: 1234 },
sort: { geo.c: -1 }
}]]>
</queryString>
<field name="xxx" class="java.lang.Integer"/>
<field name="geo.c" class="java.lang.String"/>
<variable name="var_2113924770" class="java.lang.Integer" resetType="Group" resetGroup="group_2113924770" calculation="Count">
<variableExpression><![CDATA[$F{geo.c}]]></variableExpression>
</variable>
<filterExpression><![CDATA[$F{geo.c} != null]]></filterExpression>
<group name="group_2113924770">
<groupExpression><![CDATA[$F{geo.c}]]></groupExpression>
</group>
</subDataset>
This works well for charts (results actually get grouped). Now I want to display grouped geo.c data in a Table instead of a Chart but the output looks like this:
This is how my charts look using the same dataset:
I can't put <dataset incrementType="Group" incrementGroup="group_2113924770"> into tables, and the rows don't get grouped by Country.. I tried the "printRepeatedValues" option without success. I think here is the main problem.
The definition of the dataset in a table looks like:
<jr:table xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd">
<datasetRun subDataset="data_2113924770" uuid="8c9a7682-73d6-4c85-b37d-5333eb7806cb">
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
</datasetRun>
On trying to put dataset into it, the following error appears:
Error loading the report template: invalid content beginning with "dataset" found, "datasetRun" exptected.
Question: How to avoid the repeating key values and have every country only once?

Answer 1

In your variable declaration you have "Count"-calculation:
<variable name="var_2113924770" class="java.lang.Integer" resetType="Group" resetGroup="group_2113924770" calculation="Count">
<variableExpression><![CDATA[$F{geo.c}]]></variableExpression>
</variable>
You should have "Sum". That will solve it for you, if I have understood your problem correctly.

Answer 2

Even the Crosstab element is looking more complicated, it has it's own aggregation and therefore works for my case. Tables do not work well with subDatasets.
This did the job perfectly:
<crosstab>
<reportElement uuid="d276ffa1-21e0-4ed8-8227-9655b60db25d" x="0" y="0" width="802" height="469"/>
