Description

When I use spellcheck.q in my query to define what will be "spellchecked", I always have this error, for every configuration I try :

java.lang.NullPointerException

All my other functions works great, this is the only thing which doesn't work at all, just when i add "&spellcheck.q=my%20sentence" in the query...

Example of a query :
http://localhost:8983/solr/db/suggest_full?q=american%20israel&spellcheck.q=american%20israel

In solrconfig.xml :

<searchComponent name="suggest_full" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">suggestTextFull</str>
<lst name="spellchecker">
<str name="name">suggest_full</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
<str name="field">text_suggest_full</str>
<str name="fieldType">suggestTextFull</str>
</lst>
</searchComponent>

<requestHandler name="/suggest_full" class="org.apache.solr.handler.component.SearchHandler">
<lst name="defaults">
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">suggest_full</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.onlyMorePopular">true</str>
</lst>
<arr name="components">
<str>suggest_full</str>
</arr>
</requestHandler>

I'm using SolR 3.3, and I tried it too on SolR 4.0
