Hi Olaf You're doing everything right. The problem is that the datagrid tag was made for JSP 1.2 working with JSTL 1.0. I will try to modify the tag to see if I can make it work with JSP 2.0. It shouldn't be a lot of work. Regards, Néstor Boscán -----Mensaje original----- De: Olaf Bergner [mailto:[EMAIL PROTECTED] Enviado el: Miércoles, 29 de Diciembre de 2004 05:36 p.m. Para: taglibs-user@jakarta.apache.org Asunto: [datagrid] Cannot use EL in attribute items I am currently evaluating the datagrid tag and in the process of porting a simple homegrown pager. Our environment: JBoss 3.2.6 JSTL 1.1 standard-1.1.2.jar Java 1.4.2. The list to be displayed is stored in session scope in the property 'filteredOrganizations' of the form-bean 'organizationSearchForm', i.e. the following struts tag <logic:iterate name="organizationSearchForm" property="filteredOrganizations" ...></logic:iterate> works. My first problem was JBoss complaining that according to the TLD the attribute 'items' does not accept an EL expression, so that compilation failed. I modified the datagrid TLD so that the rtexprvalue attribute now reads 'true'. Now, a <ui:dataGrid items="${organizationSearchForm.filteredOrganizations}" ...> gives me an java.lang.IllegalArgumentException at org.apache.taglibs.datagrid.DataGridTag.setItems(DataGridTag.java:928). The collection stored in organizationSearchForm.filteredOrganizations is of type java.util.List, a java.util.ArrayList, to be exact. Since our web.xml declares version 2.4 I understand that EL is enabled by default and any EL expression is evaluated by the web container, so that the datagrid tag should be passed a java.util.List instance. Is this assumption correct? What am I doing wrong here? Any help would be greatly appreciated, since this beast looks just like what we need. - Olaf - -------------------------------------------- Easynet GmbH (http://www.de.easynet.net) Olaf Bergner, System Integrations Harburger Schlossstrasse 1, D-21079 Hamburg fon: +49-40-77175-434, fax: +49-40-77175-519 # Easynet is part of the easynet group plc (www.Easynetgroup.net) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
