StatsComponent doesn't work if field's type is TextField - can I change field's type to String

[Elran Dvir]

Hi all,

StatsComponent doesn't work if field's type is TextField.
I get the following message:
"Field type 
textstring{class=org.apache.solr.schema.TextField,analyzer=org.apache.solr.analysis.TokenizerChain,args={positionIncrementGap=100,
sortMissingLast=true}} is not currently supported".

My field configuration is:

<fieldType name="mvstring" class="solr.TextField" positionIncrementGap= "100" 
sortMissingLast="true">
            <analyzer type="index">
                <tokenizer class="solr.PatternTokenizerFactory" pattern="\n" />
            </analyzer>
</fieldType>

<field name="myField" type="mvstring" indexed="true" stored="false" 
multiValued="true"/>

So, the reason my field is of type TextField is that in the document indexed 
there may be multiple values in the field separated by new lines.
The tokenizer is splitting it to multiple values and the field is indexed as 
multi-valued field.

Is there a way I can define the field as regular String field? Or a way to make 
StatsComponent work with TextField?

Thank you very much.
