errorValue

Class: com.microstrategy.web.app.taglibs.ErrorValueTag

Usage:

This custom tag allows to display different information about the exception that was generated while executing the page. It is recommended to use it together with the {@link IfErrorValueTag} to verify whether there was an error on the page.
The following example shows the error message using a special formatting only if an error was found during the execution of the page: 
 <web:ifErrorValue>
   <web:then>
     <TABLE ID="errorTable" NAME="errorTable" CELLSPACING="0" CELLPADDING="0" BORDER="0" WIDTH="90%">
       <TR>
         <TD ALIGN="LEFT">
           <HR SIZE="1" /><SPAN CLASS="error-title><web:errorValue property="title"/></SPAN><BR /><BR />
           <web:errorValue property="message"/><BR />
           <HR SIZE="1" /><BR />
         </TD>
       </TR>
     </TABLE>
   </web:then>
 </web:ifErrorValue>
