Since I got lots of replies asking for the code, I'll just post it to the list to make
things easier. FYI: I tested the code, works for me... no guarantees that this code is
100% correct. Enjoy:
Add the following to the ColumnTag class
/* begin: added by vic - 8/14/03 */
public void doInitBody() throws javax.servlet.jsp.JspException{}
public int doAfterBody() throws javax.servlet.jsp.JspException {
BodyContent bc = super.getBodyContent();
try {
this.setBodyStuff(this.getBodyContent().getString());
bc.clear();
} catch (NullPointerException e) {
//just make bodyStuff an empty string
this.setBodyStuff("");
} catch (IOException ie) {
//do nothing
}
return SKIP_BODY;
}
private String bodyStuff;
public void setBodyStuff(String v) {
this.bodyStuff = v;
}
public String getBodyStuff() {
return this.bodyStuff;
}
/* end added by vic - 8/14/03 */
In the TableTag class, in the getHTMLData method, after the comment that says:
"// Get the value to be displayed for the column"
modify to look like the following:
.
.
.
Object value = null;
if( tag.getValue() != null ) {
/* begin: modified by vic - 8/14/03 */
String theBody = tag.getBodyStuff();
if (theBody != null) {
value = theBody;
}
//keep the value from the value attribute in case you want it
value = value + tag.getValue();
/* end: modified by vic - 8/14/03 */
} else {
.
.
.

Subject: [displaytag-user] Modified column tag to evaluate body
Hello,
I don't know if anybody else is interested in this, but I modified the
source code for my application so that the column tag evaluates the body.
This makes it really easy to throw in an additional column that is unrelated
to the collection being displayed without using the decorator.
If anybody is interested in what needs to be added/modified in the source,
shoot me an email.
Later,
- Vic
