Re: error with logic:iterate on dynabeans

[Olasoji Ajayi]

After going thru some source codes in the struts package, i discovered that 
the problem hat to do with formating, the last two colums of my table are 
DATE formats which translated to java.sql.date type in java. the bean taglib 
was looking for a resource ot determine how to format the data on those 
fields but since i did not create any resource configurations, it was 
looking for what was not there. i had to hard code a format on the 
bean:write tag using the format attribute. i dont think this is a neat idea 
especially for beginers like me who want to whip up a working application 
with as little advanced configurations as possible so we can learn one thing 
at a time, (resource bundles/intenationalizatin, jdbc, etc) and still get 
struts to give us some workable defaults.

is a RowSetDynaClass containing the result of thequery.<bean:define id="cols" name="rowSet" property="dynaProperties"/>   <table border="2">     <tr>       <logic:iterate id="col" name="cols">         <th><bean:write name="col" property="name"/></th>       </logic:iterate>     </tr>     <logic:iterate id="row" name="rowSet" property="rows">       <tr>         <logic:iterate id="col" name="cols">           <td>             <bean:write name="row" property="<%=((DynaProperty)col).getName() %>"/>           </td>         </logic:iterate>       </tr>     </logic:iterate>   </table>when i replace the <%= ((DynaProperty)col).getName()%>   with one of thevalues of the column, the program runs correctly (i.e. the entire table ispopulated with the values of the column as expected). why is it not workingand if it can't what other method can i use to dynamicaly generate theproperty value for the tag
