I'm testing to see if I can use either of the refactored tables to use the
export functionality in a Tiles-based application (doesn't work in 0.8.5
version of displaytag). While I'm at it, I thought I'd do some comparisons:
1. Building (cd to project directory, execute "ant"):
* table-york: built successfully in 9 seconds (w/ some deprecation errors)
[PASS]
* display09: built successfully in 20 seconds (seem to include Javadocs and
sample app though) [PASS]
* displaytag (current): doesn't compile out-of-the-box [FAIL]
2. Ant Script - how descriptive are the tasks ("ant -projecthelp")
* table-york: targets are listed, but no descriptions [FAIL]
* display09: not very descriptive [FAIL]
* displaytag: simple with descriptions [PASS]
~ Maybe this one wasn't a good test, eh?
3. Exporting in Tiles - (deployed display.jar in WEB-INF/lib of my appfuse
application)
* table-york: error when page first loads:
[ServletException in:/WEB-INF/pages/userList.jsp]
/WEB-INF/pages/userList.jsp(27,0) Unable to load class table'
REASON: No .tld file in META-INF of the .jar file (I'm using the following
to declare this taglib:
<%@ taglib uri="http://jakarta.apache.org/taglibs/display"; prefix="display" %>
WORKAROUND: Copied display.tld to WEB-INF, renamed declaration above and
made an entry in web.xml for this tag.
RESULT: 'Attribute cellspacing invalid according to the specified TLD'
WORKAROUND: Removed attribute from <display:table>.
RESULT: 'Attribute cellpadding invalid according to the specified TLD'
WORKAROUND: Removed attribute from <display:table>.
RESULT: 'Attribute width invalid according to the specified TLD'
WORKAROUND: Removed attribute from <display:column>.
RESULT: Error page displayed with the following stacktrace:
java.lang.StringIndexOutOfBoundsException: String index out of range: -7 at
java.lang.String.substring(String.java:1444) at
java.lang.String.substring(String.java:1411) at
org.displaytag.HtmlTableView.parseURI(HtmlTableView.java:630) at
org.displaytag.HtmlTableView.getURIParams(HtmlTableView.java:649) at
org.displaytag.HtmlTableView.getSortURI(HtmlTableView.java:722) at
org.displaytag.HtmlTableView.getHeaderTitle(HtmlTableView.java:596) at
WORKAROUND: Removed requestURI attribute, which was:
requestURI="<%=request.getContextPath()+thisURL.getPath()%>"
[FAIL] CSV link does the same as 0.8.5, XML link produces nothing and there
is no Excel link.
I reset the app to it's original state and put display09's .jar file in
WEB-INF/lib.
* display09
RESULT: 'Attribute styleClass invalid according to the specified TLD'
WORKAROUND: Removed attribute from <display:table>.
RESULT: None of my CSS classes work, but the page displays (easily fixed
with styleClass attribute). Same results from export as 0.8.5.
Other notes:
* I like how display09 has the "number of items found" and export options
outside of the table (rather than nested tables like in 0.8.5). The top one
should probably be a <div> though, rather than a <span>.
* In table-york, "&" should be escaped with "&" when creating URLs to
display in HTML for XHTML compliance.
So the final result - upgrading to the "next generation" of the displaytag was
easier with display09. By this, I mean getting the page to display, rather
than getting it to display exactly as before.
Here is the final HTML output from both tables (I don't know where the "d-9732"
stuff comes from).

Don't know if this will help anyone, but it's a worthy migration comparison I
think.
