    <p>I am trying to insert a object but it throwns me the <code>Error: dehydrating property value for FrancosPoS.DBMapping.order.obs</code></p> <p>I've looked here for</p> <p><a href="https://stackoverflow.com/questions/10867390/nhibernate-error-dehydrating-property-what-the-heck-is-this">NHibernate: Error dehydrating property - What the heck is this?</a> ,</p> <p><a href="https://stackoverflow.com/questions/11482106/nhibernate-error-dehydrating-property-value">NHibernate - Error dehydrating property value</a> and</p> <p><a href="https://stackoverflow.com/questions/1902219/receiving-index-out-of-range-with-nhibernate">Receiving Index Out of Range with NHibernate</a>, but none of them worked.</p> <p>I have checked and re-checked my mapping to multiple columns declarations but did not find any problem.</p> <p>My clue is that the problem has something to do with the bigint on the MySQL database and the <code>identity generator</code>. When I change it to <code>increment</code> the dehydrating error goes away and the <code>Index out of range</code> exception appears.</p> <p>Additionally, this is happening on the <code>Session Save</code> call. With the <code>increment</code> generator, the error happens at <code>commit</code> time.</p> <p>Here is my order xml mapping:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;hibernate-mapping assembly="FrancosPoS" namespace="FrancosPoS.DBMapping" xmlns="urn:nhibernate-mapping-2.2"&gt; &lt;class name="order" table="`order`" lazy="true" &gt; &lt;id name="idOrder"&gt; &lt;generator class="identity" /&gt; &lt;/id&gt; &lt;many-to-one lazy="false" name="employee"&gt; &lt;column name="idEmployee" sql-type="bigint(20)" not-null="false" /&gt; &lt;/many-to-one&gt; &lt;many-to-one lazy="false" name="customer"&gt; &lt;column name="idCustomer" sql-type="bigint(20)" not-null="false" /&gt; &lt;/many-to-one&gt; &lt;many-to-one lazy="false" name="address"&gt; &lt;column name="idAddress" sql-type="bigint(20)" not-null="false" /&gt; &lt;/many-to-one&gt; &lt;property name="date"&gt; &lt;column name="date" sql-type="datetime" not-null="true" /&gt; &lt;/property&gt; &lt;property name="bakingTime"&gt; &lt;column name="date" sql-type="datetime" not-null="false" /&gt; &lt;/property&gt; &lt;property name="price"&gt; &lt;column name="price" sql-type="decimal(8,4)" not-null="true" /&gt; &lt;/property&gt; &lt;property name="cash"&gt; &lt;column name="cash" sql-type="tinyint(1)" not-null="false" /&gt; &lt;/property&gt; &lt;property name="credit"&gt; &lt;column name="credit" sql-type="tinyint(1)" not-null="false" /&gt; &lt;/property&gt; &lt;property name="houseNumber"&gt; &lt;column name="houseNumber" sql-type="bigint(20)" not-null="false" /&gt; &lt;/property&gt; &lt;property name="complement"&gt; &lt;column name="complement" sql-type="bigint(20)" not-null="false" /&gt; &lt;/property&gt; &lt;property name="obs"&gt; &lt;column name="obs" sql-type="varchar(350)" not-null="false" /&gt; &lt;/property&gt; &lt;bag name="orderPsi" table="ordPsi" cascade="all" inverse="true"&gt; &lt;key column="idOrdPastaI" /&gt; &lt;one-to-many class="ordPsi" /&gt; &lt;/bag&gt; &lt;/class&gt; &lt;/hibernate-mapping&gt; </code></pre> <p>And the cs class:</p> <pre><code>public partial class order { public order() { } public virtual long idOrder { get; set; } public virtual employee employee { get; set; } public virtual customer customer { get; set; } public virtual address address { get; set; } public virtual System.DateTime date { get; set; } public virtual System.Nullable&lt;System.DateTime&gt; bakingTime { get; set; } public virtual string price { get; set; } public virtual System.Nullable&lt;int&gt; cash { get; set; } public virtual System.Nullable&lt;int&gt; credit { get; set; } public virtual System.Nullable&lt;long&gt; houseNumber { get; set; } public virtual System.Nullable&lt;long&gt; complement { get; set; } public virtual string obs { get; set; } public virtual IList&lt;ordPsi&gt; orderPsi { get; set; } } </code></pre> <p>Here is the inner exception followed by the stack trace:</p> <pre><code>"Parameter index is out of range." at MySql.Data.MySqlClient.MySqlParameterCollection.CheckIndex(Int32 index) at MySql.Data.MySqlClient.MySqlParameterCollection.GetParameter(Int32 index) at System.Data.Common.DbParameterCollection.System.Collections.IList.get_Item(Int32 index) at NHibernate.Type.NullableType.NullSafeSet(IDbCommand cmd, Object value, Int32 index) at NHibernate.Type.NullableType.NullSafeSet(IDbCommand st, Object value, Int32 index, Boolean[] settable, ISessionImplementor session) at NHibernate.Persister.Entity.AbstractEntityPersister.Dehydrate(Object id, Object[] fields, Object rowId, Boolean[] includeProperty, Boolean[][] includeColumns, Int32 table, IDbCommand statement, ISessionImplementor session, Int32 index) </code></pre>

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.
