Hello I am using TC5.5.9,JSTL1.1,Struts1.2 With this code: <table width="476" height="110" border="1"> <tr> <td> </td> <td><html:multibox property="strArray" value="Value1"/></td> <td> </td> </tr> <tr> <td> </td> <td> </td> <td> </td> </tr> </table> I have made sure my actionForm has the s/getter for checkbox1, checkbox2 & strArray. Made sure the reset is setting the booleans to false. The page comes up without the html:multibox tag, so everything else is correct. Except for the error below. It seems like a tag library issue. Any and all insight welcomed. tia.
