Mysql DATA TOO LONG

When I add a field like this one :

<field attributeName="Immeuble" type="sqlLookup" defaultMode="E" top="7" left="824" width="176" height="19">
         <description></description>
         <label language="FR">Immeuble</label>
         <label language="EN">??</label>

         <param name="dbURL">jdbc:oracle:thin:@localhost:1521:compiere</param>
         <param name="dbDriver">oracle.jdbc.driver.OracleDriver</param>
         <param name="dbLogin">comp302</param>
         <param name="dbPassword">compiere</param>

         <param name="dbQuery">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaa</param>

         <param name="cols">value;name;</param>
         <param name="updates">Immeuble=2;</param>

      <param name="hiddencols">ad_org_id;value</param>
      <param name="hiddenupdates">Immeuble_value=1;Immeuble_value=2;</param>
     </field>

I've got with Tobflow with MySQL this exception :

Exception invoking listener method uploadModel of component admin/ModelAdmin: Failure invoking listener method 'public void com.audaxis.tobflow.tapestry.page.admin.ModelAdmin.uploadModel()' on $ModelAdmin_176@3c1[admin/ModelAdmin]: (HibernateTemplate): encountered SQLException [Data truncation: Data too long for column 'value' at row 1]; nested exception is java.sql.BatchUpdateException: Data truncation: Data too long for column 'value' at row 1
