[displaytag-user] Adding attributes

[John Yearous]

Title: Message

I've been working with display tag code and want to add an attribute to it. The attribute I want to add needs to go in the display:table tag. I've added the getter and setter methods to the TableTag class and added the attribute to the display.tld file, but when I add it to my jsp and try and compile I get this error:

"deletePage is not a property of org.apache.taglibs.display.TableTag"

 

DeletePage is the name of the attribute that I want to add. Also, TableTag compiles w/o any errors or warnings.

 

Here's some code from my jsp using the DisplayTag lib:

 

<display:table width="75%" name="test" deletePage="test.html">
  <display:column property="id" title="ID" headerStyleClass="ListTableHeader"/>
  <display:column property="name"  headerStyleClass="ListTableHeader" />
  <display:column property="email"  headerStyleClass="ListTableHeader"/>
  <display:column property="status" headerStyleClass="ListTableHeader"/>
  <display:column property="description" title="Comments" headerStyleClass="ListTableHeader"/>
</display:table>

 

(If I remove the deletePage attribute from the tag, it compiles w/o errors or warnings)

 

Here's what's in the display.tld:

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<taglib>
  <tlibversion>1.0</tlibversion>
  <jspversion>1.1</jspversion>
  <shortname>display</shortname>
  <uri>\WEB-INF\display.tld</uri>
  <info>A description of the display tag library goes here...</info>
  <tag>
    <name>table</name>
    <tagclass>org.apache.taglibs.display.TableTag</tagclass>
    <teiclass>org.apache.taglibs.display.TableTagExtraInfo</teiclass>
    <bodycontent>JSP</bodycontent>
    <attribute>
      <name>john</name>
      <required>false</required>
      <rtexprvalue>true</rtexprvalue>
    </attribute>

 ...

 

And here's what's in the TableTag.java:

 

private String deletePage = null;

 

private void setDeletePage(String thePage)
{
     this.deletePage = thePage;
}

 

 private String getDeletePage()
 {
     return this.deletePage;
 }

 

 

The rest of the code has remained intact from when I downloaded it. Also, I ran the code without any problems to see how it worked before I added the deletePage stuff. Any idea as to why it's not working? Thanks.
