Float data is being returned as strings rather than numbers

[chuck.rossi]

We recently upgraded to SmartClient v10.1p_2016-02-24/PowerEdition Deployment (built 2016-02-24). We are now seeing cases where floating point numbers (Double's in Java, float in the SmartClient data source) are being returned as strings rather than as numbers.

We are using Chrome on the Mac, Version 48.0.2564.116 (64-bit).

Here is the datasource:
<DataSource
ID="StudyIncidenceDataDS"
serverType="generic"
>
<fields>
<field name="totalPopulation" title="total population" type="integer" isIdentity="false" useAsFormField="true"/>
<field name="numberMutations" title="number mutations" type="integer" isIdentity="false" useAsFormField="true"/>
<field name="incidence" title="incidence" type="float" isIdentity="false" useAsFormField="true"/>
<field name="id" title="id" type="text" isIdentity="false" useAsFormField="true" length="36" hidden="true" primaryKey="true" />
<field name="study" title="study" type="text" />
<field name="biomarker" title="biomarker" type="text" />
<field name="disease" title="disease" type="text" />
</fields>
<serverObject ID="incidenceDataHandler" lookupStyle="new" className="com.nofone.mm.dmi.IncidenceDataDMI"/>
</DataSource>

An example of a response that we are seeing is:

See the bolded line where the incidence value is a string even though in the data source definition it was defined as a float.

The Java code that generates this data is:
protected Map<String, Object> mapValues(IncidenceData data,
PersistentObjectManager pom, DSRequest dsRequest) throws Throwable {
Map<String,Object> map = new Hashtable <String,Object>();
map.put("id", data.getId());
if (data.getCbioportalStudy() != null) {
map.put("study", data.getCbioportalStudy().getStudyLongName());
}
map.put("biomarker", data.getBiomarker().getFullName());
map.put("disease", data.getDisease().getName());
if (data.getIncidence() != null) {
map.put("incidence", data.getIncidence());
}
if (data.getTotalPopulation() != null) {
map.put("totalPopulation", data.getTotalPopulation());
}
if (data.getNumberMutations() != null) {
map.put("numberMutations", data.getNumberMutations());
}
return map;
}

where data.getIncidence() is returning a double.

We did not see this problem in the prior version of SmartClient that we were using, v10.0p_2015-09-22/PowerEdition Deployment (built 2015-09-22).

Has this problem been reported before? Is there any chance that it is fixed in newer SmartClient 10 builds?

Thanks

This is by design - conversion to String is done automatically for values that cannot be represented in JavaScript without loss of precision. See dataSourceField.stringInBrowser for how to turn this off if it is not desirable for you.
