Howard M. Lewis Ship commented on TAP5-568:
-------------------------------------------
Oops. This is a Tapestry 4 bug!
> javascript is not nor showing nor being rendered within the .html. we have a
> prototype and implemented the same things?
> -----------------------------------------------------------------------------------------------------------------------
>
> Key: TAP5-568
> URL: https://issues.apache.org/jira/browse/TAP5-568
> Project: Tapestry 5
> Issue Type: Bug
> Components: JavaScript
> Environment: OS: WindowsXP
> Server: JBoss
> IDE: Eclipse
> Tapestry: version 3.0.3
> Java: J2re1.4.2_16
> Reporter: Frederick Gaetos
> Original Estimate: 120h
> Remaining Estimate: 120h
>
> Here's what happened:
> We're going to implement a component based javascript within our tapestry
> project (big project).
> We have two projects.
> 1.)Prototype HelloWorld Tapestry project that was able to produce "Hello
> World" message that is invoked by javascript. (this thing worked!)
> 2.) Second was a project where we are going to implement the same scenario
> wherein a button will invoke a page. And when the said page is rendered, it
> will also display a "Hello World" since it has the same javascript
> implementation similar with "project number one" ("Prototype HelloWorld
> Tapestry Project").
> The "Prototype HelloWorld Tapestry project" is made for the purpose of
> implementing component based javascript within an expert system project.
> ...However, for some reasons it did NOT worked...
> Thus, No <script> tag was rendered within the second scenario/ Project.
> Please see more of the details and explanation below.
> here's the prototype:

> Note:
> The last two lines are important...
> paymentMethodsPage.setSalePaymentMethod(new SalePayMethod());
> cycle.activate(paymentMethodsPage);
> =============================================================================================
> What we are confuse of is that "why is it that when we implement the same
> HelloWorld alert scenario, it is not rendering the alert javascript to the
> .html".
> P.S.
> - we even tried calling the prototype within our expert system project
> (project 2) and it worked.
> - we verified if our .page xml is correct (project 2)...
> - we suspect that the concern can be rectified by analyzing the
> "sales_paymentmodes.page" and there might be some syntax that is preventing
> it from rendering the script.
>
> I have already spent five days in doing everything I could to check any loop
> holes with no luck. Hope you could help us out.
> Thanks!
