Re: How to include broken javascript?
Why can't you include those exact scripts directly in your page or component?

Re: How to include broken javascript?
Isn't Shell's delegate parameter (and functionality) appropriate for you? By using delegate you can include the scripts in the head of the page.

Latest 4.1.1 tacos compatibility
I just downloaded 4.1.1 SNAPSHOT and it appears that there is a tacos compatibility error with the latest build.

Re: Latest 4.1.1 tacos compatibility
As I know T4.1.1 is not compatible with tacos at all. T4.1.1 has more enhanced functionality and it will have support for advanced dojo components like tree in the future.

Re: [OT] your tomcat config for you tapestry apps
Those configuration ( tweaking ) questions arise from time to time. Even if it's a bit OT, it'd be nice to see all those recommendations in the wiki over at http://wiki.apache.org/tapestry/ Just like we have SuccessStories, we could have ConfigurationStories. Anyone willing to make the start? Daniel Jue wrote: We are still in the development stages, but we'll be running Tomcat 5.5.17 behind IIS and using the isapi redirector. Single JVM, with default memory settings right now. Since our Tapestry pages look like standard html (i.e. they don't end in .jsp), and since our IIS instance is shared with other web apps, the redirector is told to forward anything in our app's sub directory to Tomcat. So far the only issue I'm having at the moment is Hot Deploy is broken. This is a known problem and it has to do with the way the Windows file system locks the resources (especially Jar files, but sometimes others). Just FYI, the work-around(s) that are available are not real solutions. They involve making tomcat create a temporary copy of the web app for each time you hot deploy. You eat up space really quick (because it doesn't ever clean the temp directories) and it's slow. See the Tomcat newsgroups and bug reports for more info on this, since it's not Tapestry related. In addition, I chose Tomcat because: I'm semi-familiar with it (seen it used with success in the past), compared to OC4J/JBOSS After seeing how some Oracle documentation was written, I just didn't trust OC4J I found lots of threads online about how OC4J sucked I like the Apache foundation products. I knew at the time I could integrate it with Eclipse The amount of online articles/support/tutorials was sufficient for me. A lot of good Tapestry tutorials used Tomcat.

Re: [OT] your tomcat config for you tapestry apps
If I can get through my configuration woes here I might make a contribution to it. Other than my current problem, the setup seems to be pretty good and scalable. Along the same lines, a page on setting up an easily testable development environment could be good also. We use maven, hsqldb, and jetty to test everything on the developer's machine and it's fantastic.

Even if it's a bit OT, it'd be nice to see all those recommendations in the wiki over at http://wiki.apache.org/tapestry/ Just like we have SuccessStories, we could have ConfigurationStories. Anyone willing to make the start? Daniel Jue wrote: We are still in the development stages, but we'll be running Tomcat 5.5.17 behind IIS and using the isapi redirector. Single JVM, with default memory settings right now. Since our Tapestry pages look like standard html (i.e. they don't end in .jsp), and since our IIS instance is shared with other web apps, the redirector is told to forward anything in our app's sub directory to Tomcat. So far the only issue I'm having at the moment is Hot Deploy is broken. This is a known problem and it has to do with the way the Windows file system locks the resources (especially Jar files, but sometimes others). Just FYI, the work-around(s) that are available are not real solutions. They involve making tomcat create a temporary copy of the web app for each time you hot deploy. You eat up space really quick (because it doesn't ever clean the temp directories) and it's slow. See the Tomcat newsgroups and bug reports for more info on this, since it's not Tapestry related. In addition, I chose Tomcat because: I'm semi-familiar with it (seen it used with success in the past), compared to OC4J/JBOSS After seeing how some Oracle documentation was written, I just didn't trust OC4J I found lots of threads online about how OC4J sucked I like the Apache foundation products. I knew at the time I could integrate it with Eclipse The amount of online articles/support/tutorials was sufficient for me. A lot of good Tapestry tutorials used Tomcat.

Two rows for every item in a Contrib:Table's source collection
Hi, I'd like to use the Contrib:Table to display a collection of search results, but I'm not sure it can provide me what I want...any suggestions would be greatly appreciated. Our GUI designer wants us to provide search results in a table format like this: - | 1 | 337-360| lorem ipsum | blah | - | Document 337-360 is about blah and ..| - | 2 | 701-488| foo mellon| fsaj | - | Document 701-488 summary/except inf..| etc. Each result to be displayed would be rendered across 2 rows of a table, the second row with a colspan of 4. I'm looking at Kent Tong's excellent book (page 257) and I see that you can break up the Table component into its composite pieces like this: span jwcid=@TableView span jwcid=@TablePages/ table trspan jwcid=@TableColumns//tr tr jwcid=@TableRowstd jwcid=@TableValues//tr /table /span /span But I'm at a bit of a loss as to how to proceed. Should I extend my own TableRows object and have it spit out a separate row after it usually would? Any one out there have any code samples of something similar??

page flow management suggestions?
Hi there -- does anyone have any suggestions about tools to use to manage page flow within an application that works well with the Tapestry and an AJAX flow? I have looked a little at Spring's Webflow and there is also Seam from the Jboss people. I want to have the ability to be able to describe the flow irrespective of how that flow is rendered. By this I mean that sometimes the next step is going to be issuing some AJAX update to the existing page, while at other points it will result in an entirely new page. The Spring Webflow stuff seems to want to issue new pages, and while I am going to start that way I want to be able to gradually move to a more AJAXy way do doing things. I know to some degree I am going to run into the old problem of where to keep session state - on the client or the server. I am hoping that there will be help from one of these flow frameworks out there. Does anyone have any experience with any solutions out there? -Pat

When I submit, however, it is still null. When the page comes back (after failing validation), the max is now set properly, and simply pressing submit again will succeed.

Re: How to observe property binding events
Yes, but the usefulness of my answer largely depends on how clever/efficient you are trying to be doing it. Now, there is IBinding. The one object to bind them all ;) If you work your way down the type hierarchy you'll find AbstractBinding, which holds the method you care about most - setObject. This will be called by tapestry when managing all of the page properties automagically for you. Some of the magic happens in (for your exact case at least) org.apache.tapestry.enhance.ParameterPropertyWorker. The other half of the work happens in each specific binding implementation that will handle these set/get object calls..(Like ognl bindings, etc..) I'm not sure where you are going with this but I guess you could use the hivemind chain of command service sort of configuration (like I did for org.apache.tapestry.services.ComponentRenderWorker ) to generically call a single interface method for a hivemind configuration point...Then you can contribute as many workers into the chain you like if you decide that you have more than one use for it. Again...Not knowing what you are doing - and taking the exact parameters given I'd probably extend and override the default ParameterPropertyWorker (a hivemind service, so replacing it inline with what Tapestry does already should be easy ) and just override whatever section of code I needed to in that implementation to inject + call my service reference. It may look a little complicated in there at first, but the whole org.apache.tapestry.enhance package is filled with lots of different enhancement works - and most of them inject a service into the object they work on...So finding an easier to follow worker to reference before modifying ParameterPropertyWorker might be easier. Hope that helps. On 10/6/06, Epstein, Ezra [EMAIL PROTECTED] wrote: I've got a component which accepts a parameter. I want to listen (receive a callback) when the parameter is set (bound).
