    <p>The code below, using boost::spirit, used to work with boost 1.44 and boost 1.49:</p> <pre><code>qi::string("a_token") [ boost::phoenix::bind(&amp;node_t::some_func, *qi::_val, true) ] </code></pre> <p>I updated boost to version 1.53, but now this code does not compile anymore. g++ complains about</p> <pre><code>error: pointer to member type 'void (node_t::)(bool)' incompatible with object type 'boost::error_cant_deduce_type' </code></pre> <p>I can't figure out how to fix it. The following code compiles :</p> <pre><code>qi::string("a_token") [ boost::phoenix::bind(&amp;node_t::some_func, (node_t*)0, true) ] </code></pre> <p>So I guess the problem is with qi::val_... Did the API of boost::spirit changed or am I missing an include file ?</p> <p>I'm using g++4.7, with --std=c++0x.</p> <p>Here I tried a small test case to reproduce the problem. The error message is not the same (but it's still big !), but once again the dereference operator seems to be the problem.</p> <pre><code>#include &lt;boost/spirit/include/qi.hpp&gt; #include &lt;boost/spirit/include/phoenix_operator.hpp&gt; #include &lt;boost/spirit/include/phoenix_bind.hpp&gt; #include &lt;boost/shared_ptr.hpp&gt; struct node_t { void foo(bool){} }; int main() { namespace qi = boost::spirit::qi; boost::spirit::qi::rule &lt; std::string::const_iterator, boost::shared_ptr&lt;node_t&gt;(), boost::spirit::ascii::space_type &gt; rule; rule = qi::string("true") [boost::phoenix::bind(&amp;node_t::foo, *qi::_val, true)]; } </code></pre>

    2. COForgot to say: _val should be a shared_ptr<node_t>. I'll try to make a simple test case.

    3. COusing `boost::shared_ptr<node_t>()` in the rule signature the original error appears. Defining BOOST_SPIRIT_USE_PHOENIX_V3 before the inclusion of headers [makes it compile](http://liveworkspace.org/code/2hIun1$3).

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.
