    <p>This is a sample that represents my problem. The map will serialize perfectly fine unless finalTime is greater than 25. With boost unit testing I was given a std::exception input stream error. Also, this code works fine using polymorphic_text_archives. The error occurs while reading in the map.</p> <pre><code>#include &lt;fstream&gt; #include &lt;iostream&gt; #define BOOST_ALL_DYN_LINK #define BOOST_PARAMETER_MAX_ARITY 8 #include &lt;boost/serialization/export.hpp&gt; #include &lt;boost/archive/polymorphic_iarchive.hpp&gt; #include &lt;boost/archive/polymorphic_oarchive.hpp&gt; #include &lt;boost/archive/polymorphic_binary_iarchive.hpp&gt; #include &lt;boost/archive/polymorphic_binary_oarchive.hpp&gt; #include &lt;boost/static_assert.hpp&gt; #include &lt;boost/serialization/map.hpp&gt; using namespace boost; class DoubleTest { public: DoubleTest(double d) { this-&gt;Double = d; } DoubleTest() { this-&gt;Double = 0; } void serialize(boost::archive::polymorphic_iarchive &amp; ar, const unsigned int) { ar &amp; this-&gt;Double; } void serialize(boost::archive::polymorphic_oarchive &amp; ar, const unsigned int) { ar &amp; this-&gt;Double; } double Double; }; int main(int argc, char** argv) { const std::string fileName = "test.out"; std::map&lt;float, DoubleTest*&gt; mymap; const int initialValue = 0; const int initialTime = 0; // A "finalTime" of 25 works.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
