Tapestry 5 XML tag(s)
Hello, With Tapestry 5 - where can I find information on how the new xml tags work - like t:pagelink / etc? I have done quite a bit of work with 4 and am a little disoriented without the jwcids etc. Not sure what I can put instead of 'pagelink'. I interpret entries on the component reference as attributes on the 't' tag? Thanks, -Ryan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tapestry 4.1.1 Dojo (startup question)
Hello,
Quick question with tapestry 4.1.1 - is there a default border
component or do I still have to write my own?
Using my existing border component which worked with Tapestry 4.0.x
and Dojo I now get:
FATAL: Could not load 'dojo.logging.Logger'; last tried
'__package__.js'

Instructions for building 4.1

Quick Contrib:Table question
Hello,
I am working creating a table for which the number of columns is dynamic (user
can control which columns they want displayed). What is the proper approach for
implementing the behavior?
Thus far I created an implementation of ITableColumnModel which then returns
the custom set of columns. I initially returned SimpleTableColumn instances but
was getting a 'Unable to read OGNL expression 'parsed OGNL expression' of
[EMAIL PROTECTED]/image/bands.tableColumns]: tableColumnRenderer' exception
(src below). After getting this exception I thought my approach might be wrong.
Looking over the code I was a little puzzled on how my column would extract the
values from the model etc. Looking through the contrib:table source I chanced
upon 'ExpressionTableColumn'. There are no java docs so I am not quiet sure how
it is supposed to be used. From the title I 'think' this would take ognl
expressions and retrieve the values from my data model? However, I am not quiet
sure how to contruct an instance - where/what do I use for an
ExpressionEvaluator?
Page spec:
component id=bands type=Contrib:Table
binding name=source value=tableModel/
binding name=columns value=ognl:tableColumnModel/
binding name=rowsClass value=beans.evenOdd.next/
binding name=columnsClass value=literal:title/
/component
My TableColumnModel (only one field, was trying to get it working first..):
public class BandSummaryColumnModel implements ITableColumnModel {
private static final Logger logger =
Logger.getLogger(BandSummaryColumnModel.class);
private MapString, ITableColumn _columns;
public BandSummaryColumnModel() {
if(logger.isDebugEnabled()) logger.debug(Instantiating
BandSummaryColumnModel);
_columns = new HashMapString,ITableColumn();
_columns.put(callPointH,new
SimpleTableColumn(callPointH,callPointH,true));
}
public int getColumnCount() {
if(logger.isDebugEnabled()) logger.debug(Column count: +
_columns.size());
return _columns.size();
}
public ITableColumn getColumn(String string) {
if(logger.isDebugEnabled()) logger.debug(Column requested: + string);
return _columns.get(string);
}
public Iterator getColumns() {
if(logger.isDebugEnabled()) logger.debug(Column iterator requested);

Re: Quick Contrib:Table question (how to get an ExpressionEvaluator?)
Thanks,
That is much simpler!
For the ExpressionTableColumn I need a ExpressionEvaluator as the last
parameter. I think it is a tapestry service (still digging through the binding
files), thought this would work:
@InjectObject(infrastructure:tapestry.ognl.ExpressionEvaluator)
public abstract ExpressionEvaluator getExpressionEvaluator();
(also tried engine-service)
However I get a nice exception that it can't find the service etc.

Re: PermGen space - Caching is ON

As Martin said, enabling caching should fix the problem. Tapestry will only generate (and cache) the classes for each page/component one time with caching enabled. In a production environment, you really shouldn't run into this, since you would have caching enabled and you wouldn't be hot redeploying your application. James Hi all, This problem is very common with Tapestry applications. This is due to the fact that Tapestry uses cglib to generate classes at runtime. Java uses a separate Heap space called PermGenSpace to put meta-data about classes, which is never garbage collected (this is normal since normally, classes never change...) but with cglib, classes are generated, which add to the PermGenSpace. And the next time your application is deployed, new classes are generated which add to the PermGenSpace, etc... So it fills and become full. So this problem is common to Java+Tapestry/cglib+deployed webapps. I hope this explaination is clear. Else ask questions. -jec Harvey, David a écrit : Hello all, We've been having occasional problems with PermGen out of space errors

that 'magical' layer - the dynamically generated object which calls

Re: Table component problem
Hello,
As is usually the case right after sending the email below I
figured out my problem. I had spent over an hour digging and was
quiet perplexed. I needed to add a 'Persist' annotation to the 'get'
method used by the source. I did call the set method in the
pageBeginRender - which does not appear to be called when resorting
the table (don't quiet understand why yet...). However, any pointers
on how-to step into the 'dynamically' generated code/proxy would be
appreciated for future reference =)

Retrieving the HiveMind registry built by ApplicationServlet
Hello, How do I snag the HiveMind registry which is built by processing the hivemodule.xml in WEB-INF? I am trying to expose my Hivemind service as a webservice (JAXRPC). My Hivemind service is used in serveral pages presently. Looking over the code for the ApplicationServlet it looks like it stores it in the ServletContext which isn't visible to my webservice implementation. Hopefully this makes sense... Should I: 1) reload the registry 2) store the registry in a static variable 3) is there another trick available?

RE: Custom component validation - two fields
I think I follow. So you only display the TextField if the checkbox was
checked (via refresh submit)?
I plowed ahead with trying to implement my own AbstractFormComponent that
would use an html template and also render some of its own content. However, I
am getting a stale link exception when I submit. Either I am setting something
up incorrectly or missing the boat on the rewind. Not exactly sure how to parse
the StaleLink page. Been diving through the list archives and source trying to
get a better idea on how component ids are generated and the rewind is done.
I can create a new form component re-using other form components - right?
To read the template I yanked code out of the BaseComponent class.
In the end, I want my custom component to display a checkbox and a textfield
(possibly a PropertySelection as well). When the form is submitted, if the
checkbox is checked but no content is contained in the textfield I want to
decorate it and add a message to the top. This component will be used at least
a dozen time on the page for different search parameters.
Gradually learning!
Thanks,
Ryan

Yup, I am using version 4. That returns the page unprocessed - jwcid and everything. From the blog (http://howardlewisship.com/blog/2004/12/tapestry-urls-half-way-there.html) I added the following to my web.xml: servlet-mapping servlet-nameapp/servlet-name url-pattern*.html/url-pattern /servlet-mapping However, I then get the login page for the application- servlet mapping is definitely doing something. Excluding some JAXRPC stuff, the other entries in my web.xml are: servlet servlet-nameKMI/servlet-name servlet-classorg.apache.tapestry.ApplicationServlet/servlet-class load-on-startup0/load-on-startup /servlet servlet-mapping servlet-nameKMI/servlet-name url-pattern/app/url-pattern /servlet-mapping servlet-mapping servlet-nameKMI/servlet-name url-pattern*.page/url-pattern /servlet-mapping filter filter-nameredirect/filter-name filter-classorg.apache.tapestry.RedirectFilter/filter-class /filter filter-mapping filter-nameredirect/filter-name url-pattern//url-pattern /filter-mapping welcome-file-list welcome-file/app/welcome-file /welcome-file-list Thanks, -Ryan On Wednesday, May 31, 2006, at 11:36AM, James Carman [EMAIL PROTECTED] wrote: Are you in tap4?

I have a test page at the root of the application which I want to invoke. From the Manning book I thought the url would look like: http://127.0.0.1:8080/app?service=page/test This is just a page for tinkering... was trying to test a new component and thought I could throw it up on a test page (instead of logging into the app and drilling through the menus).
