id="BuildingTapestryfromSource-Antlr">Antlr</h3><p>The

missing Java classes that are produced by ANTLR the first time the project is
built. To fix this:</p><ul><li>Eclipse Gradle IDE users:<ul><li>Right click o
n the <code>build.gradle</code> file within tapestry-core and click Run As

have Eclipse compile the JavaScript files and lexer classes from their
Coffeescript sources and Antlr files automatically when they change, you can do
that by configuring an additional builder for the <code>tapestry-core</code>
project:</p><ul><li>Eclipse Gradle IDE users:<ul><li>Right click on the

reasonable name, select the tasks you want to run (for example,
tapestry-core/install), and click Run.</li></ul></li></ul><h3
id="BuildingTapestryfromSource-SeleniumSetup">Selenium Setup</h3><p>It is
necessary that you have a compatible version of Firefox installed.  On a
Mac, you should install it in
~/Applications (rather than /Applications).</p><p>You should modify your
~/.bash_profile (or equivalent), to add
~/Applications/Firefox.app/Contents/MacOS to the PATH variable.</p><h3
id="BuildingTapestryfromSource-RunningIndividualTests">Running Individual
Tests</h3><p>Eclipse users:</p><ul><li>Install the <a class="external-link"

</li></ul><h3 id="BuildingTapestryfromSource-SkippingTests">Skipping
Tests</h3><p>Running the Tapestry integration tests can take 10 minutes or more
(mostly because of Selenium tests, which repeatedly start and stop the Firefox
browser), so you won't want to run them every time you try a
change.</p><ul><li>Command-line users:<ul><li><code>To build while skipping all
tests: ./gradlew build -x test</code></li><li>You can skip tests on a specific
module by adding a colon and the module name. For example: <code>-x
test:tapestry-ioc</code></li></ul></li><li>Eclipse Gradle IDE users:<ul><li>In
your External Tools Configuration, add the same -x test option as above at
Arguments > Program Arguments.</li></ul></li></ul><h3
id="BuildingTapestryfromSource-RunningtheIntegrationTestAppsManually">Running
the Integration Test Apps Manually</h3><p>The Tapestry source includes several
small web apps that are used by the automated Selenium integration tests. You
can also run these apps manually to
try out nearly every browser-visible aspect of Tapestry. Just invoke the
corresponding Gradle tasks. This is mainly useful when debugging failing
selenium tests.</p><ul><li>Command-line users:<ul><li>./gradlew
runTestApp1</li></ul></li><li>Eclipse users:<ul><li>Use the run-jetty-run
plugin in Eclipse, with the context directory selected from among the
<code>test</code> context directories. For example, in the tapestry-core
module, right click on the /src/test/app1 (or app2, etc) folder, and select Run
As > Run Jetty, then open your browser to <a class="external-link"
rel="nofollow"
href="http://localhost:8080/tapestry-core";>http://localhost:8080/tapestry-core</a></li></ul></li></ul><p>The
integration test apps are:</p><ul><li>activationctx – used
by tapestry-core integration tests</li><li>activationctx2 –
used by tapestry-core integration tests</li><li>app0 – used
only by the tapestry-hibernate integration tests</li><li><strong>app1 
211; used by most of the tapestry-core integration
tests</strong></li><li>app2 – used by tapestry-core integration
tests (HTTPS)</li><li>app3 – used by tapestry-core integration

Gradle tasks yet. Search for web.xml files in the Tapestry
source.)</li></ul><h3 id="BuildingTapestryfromSource-MakingCodeChanges">Making
Code Changes</h3><p>Once you have cloned or pulled the latest changes to your
local Git repository, you can start working on i
t. Whenever you make some changes to the codebase, it's good to have a related
issue filed in JIRA and to use a similarly named branch in your local Git
repository. For example, to create a branch for an issue with the key

</li></ul><h3 id="BuildingTapestryfromSource-SkippingTests">Skipping
Tests</h3><p>Running the Tapestry integration tests can take 10 minutes or more
(mostly because of Selenium tests, which repeatedly start and stop the Firefox
browser), so you won't want to run them every time you try a
change.</p><ul><li>Command-line users:<ul><li><code>To build while skipping all
tests: ./gradlew build -x test</code></li><li>You can skip tests on a specific
module by adding a colon and the module name. For example: <code>-x
test:tapestry-ioc</code></li></ul></li><li>Eclipse Gradle IDE users:<ul><li>In
your External Tools Configuration, add the same -x test option as above at
Arguments > Program Arguments.</li></ul></li></ul><h3
id="BuildingTapestryfromSource-RunningtheIntegrationTestAppsManually">Running
the Integration Test Apps Manually</h3><p>The Tapestry source includes several
small web apps that are used by the automated Selenium integration tests. You
can also run these apps manually to
try out nearly every browser-visible aspect of Tapestry. Just invoke the
corresponding Gradle tasks. This is mainly useful when debugging failing
selenium tests.</p><ul><li>Command-line users:<ul><li>./gradlew
runTestApp1</li></ul></li><li>Eclipse users:<ul><li>Use the run-jetty-run
plugin in Eclipse, with the context directory selected from among the
<code>test</code> context directories. For example, in the tapestry-core
module, right click on the /src/test/app1 (or app2, etc) folder, and select Run
As > Run Jetty, then open your browser to <a class="external-link"
href="http://localhost:8080/tapestry-core";
rel="nofollow">http://localhost:8080/tapestry-core</a></li></ul></li></ul><p>The
integration test apps are:</p><ul><li>activationctx – used
by tapestry-core integration tests</li><li>activationctx2 –
used by tapestry-core integration tests</li><li>app0 – used
only by the tapestry-hibernate integration tests</li><li><strong>app1 
211; used by most of the tapestry-core integration
tests</strong></li><li>app2 – used by tapestry-core integration
tests (HTTPS)</li><li>app3 – used by tapestry-core integration
tests</li><li>app4 – used by tapestry-core integration
tests</li><li>app5 – used by tapestry-core integration
tests</li><li><em>appfolder</em>  – used by tapestry-core
integration tests</li><li>cluster – used by tapestry-core
integration tests</li><li>linktrans – used by tapestry-core
integration tests</li><li>symbolparam – used by tapestry-core
integration tests</li><li>(...and a few others not yet documented, and without
Gradle tasks yet. Search for web.xml files in the Tapestry
source.)</li></ul><h3 id="BuildingTapestryfromSource-MakingCodeChanges">Making
Code Changes</h3><p>Once you have cloned or pulled the latest changes to your
local Git repository, you can start working on i
t. Whenever you make some changes to the codebase, it's good to have a related
issue filed in JIRA and to use a similarly named branch in your local Git
repository. For example, to create a branch for an issue with the key
TAP5-123:</p><div class="code panel pdl" style="border-width: 1px;"><div
class="codeContent panelContent pdl">
<pre><code class="language-java">git branch TAP5-123 origin/master</code></pre>
</div></div><p>With per-issue branches you can easily switch back and forth
between different issues without worrying about unwanted side-effects from
unfinished changes to other issues. Whenever you want to work on the TAP5-123
example issue, simply checkout that branch and start making your
changes:</p><div class="code panel pdl" style="border-width: 1px;"><div
class="codeContent panelContent pdl">
<pre><code class="language-java">git checkout TAP5-123</code></pre>

this package.</li><li>For mixins, place classes in

application to have base classes, often <em>abstract</em> base classes, that
should not be directly referenced. These should <em>not</em> go in the
<strong>pages</strong>, <strong>components</strong> or <strong>mixins</strong>
packages, because they then look like valid pages, components or mixins.
Instead, use the <em>root</em>.<strong>base</strong> package to store such base
classes.</p><div class="confluence-information-macro

id="ComponentClasses-Sub-Folders/Sub-Packages">Sub-Folders /
Sub-Packages</h2><p>Classes do not have to go directly inside the package
(pages, components, mixins, etc.). It is valid to create a sub-package to store
some of the classes. The sub-package name becomes part of the page name or
component type. Thus you might define a page component
<code>com.example.myapp.pages.admin.CreateUser</code> and the logical page name
(which often shows up inside URLs) will be
<strong>admin/CreateUser</strong>.</p><
p>Tapestry performs some simple optimizations of the logical page name (or
component type, or mixin type). It checks to see if the package name is either
a prefix or a suffix of the unqualified class name (case insensitively, of
course) and removes the prefix or suffix if so. The net result is that a class
name such as <code>com.example.myapp.pages.user.EditUser</code> will have a
page name of <code>user/Edit</code> (instead of user<code>/EditUser</code>).
The goal here is to provide shorter, more natural URLs.</p><h2
id="ComponentClasses-IndexPages">Index Pages</h2><p>One special simplification
exists for Index pages: if the logical page name is Index after removing the
package name from the unqualified class name, it will map to the root of that
folder. A class such as <code>com.example.myapp.pages.user.IndexUser</code> or
<code>com.example.myapp.pages.user.UserIndex</code> will have a page name of
<code>user/</code>.</p><p>In previous versions of Tapestry there was also the
conce
pt of a start page configured with the <code><a
href="configuration.html">tapestry.start-page-name</a></code> configuration
symbol (defaults to "start"). If a page with a name as configured with that
symbol exists at the root level, this page is used as the root URL. This has
precedence over an existing Index page. If for example you have a page class
<code>com.example.myapp.pages.Start</code> it will map to
<code>/</code>.</p><div class="confluence-information-macro

and support for it will eventually be removed. Use an Index page

Components</h2><p>The distinction between pages and component is very, very
small. The primary difference is the package name:
<em>root</em>.<strong>pages</stron
g>.<em>PageName</em> for pages, and
<em>root</em>.<strong>components</strong>.<em>ComponentType</em> for
components. Conceptually, page components are simply the <em>root
component</em> of a page's component tree.</p><p><em>For Tapestry 4 users:
there was a much greater distinction in Tapestry 4 between pages and
components, which showed up as separate interfaces and a hierarchy of abstract
implementations to extend your classes from.</em></p><h2
id="ComponentClasses-ClassTransformation">Class Transformation</h2><p>Tapestry
uses your class as a starting point. It <em>transforms</em> your class at
runtime. This is necessary for a number of reasons, including to address how
Tapestry shares pages between requests.</p><p>For the most part, these
transformations are both sensible and invisible. In a few limited cases, they
comprise a marginally <a class="external-link"
href="http://www.joelonsoftware.com/printerFriendly/articles/LeakyAbstractions.html";
rel="nofollow">leaky abstracti
on</a> – for instance, the scope restrictions on instance variables
described below – but the programming model in general supports a very
high level of developer productivity.</p><p>Because transformation doesn't
occur until <em>runtime</em>, the build stage of your application is not
affected by the fact that you are creating a Tapestry application. Further,
your classes are absolutely simple POJOs during unit testing.</p><h2
id="ComponentClasses-LiveClassReloading">Live Class Reloading</h2><p>Main
Article: <a href="class-reloading.html">Class Reloading</a></p><p>Component
classes are monitored for changes by the framework. <a
href="class-reloading.html">Classes are reloaded when changed</a>. This allows
you to build your application with a speed approaching that of a scripting
environment, without sacrificing any of the power of the Java
platform.</p><p>And it's fast! You won't even notice that this magic class
reloading has occurred.</p><p>The net result: super
productivity — change your class, see the change instantly. This is
designed to be a blend of the best of scripting environments (such as Python or
Ruby) with all the speed and power of Java backing it up.</p><p>However, class
reloading <em>only</em> applies to component classes (pages, components and
mixins) and, starting in 5.2, Tapestry IOC-based service implementations (with
some restrictions). Other classes, such as service interfaces, entity/model
classes, and other data objects, are loaded by the normal class loader and not
subject to live class reloading.</p><h2
id="ComponentClasses-InstanceVariables">Instance Variables</h2><p>Tapestry
components may have instance variables (unlike Tapestry 4, where you had to use
<em>abstract properties</em>).</p><p>Since release 5.3.2, instance variables
may be protected, or package private (that is, no access modifier). Under
specific circumstances they may even be public (public fields must either be
final, or have the @<a class="e
xternal-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/annotations/Retain.html";>Retain</a> annotation).</p><p><span>Be
aware that you will need to either provide getter and setter methods to access
your classes' instance variables, or else annotate the fields
with</span><span> @</span><a class="external-link"

id="ComponentClasses-TransientInstanceVariables">Transient Instance
Variables</h2><p>Unless an instance variable is decorated with an annotation,
it will be a <em>transient</em> instance variable. This means that its value
resets to its default value at the end of reach request (when the <a
href="page-life-cycle.html">page is detached from the request</a>).</p><div

page name of <code>user/Edit</code> (instead of user<code>/EditUser</code>).
The goal here is to provide shorter, more natural URLs.</p><h2
id="ComponentClasses-IndexPages">Index Pages</h2><p>One special simplification
exists for Index pages: if the logical page name is Index after removing the
package name from the unqualified class name, it will map to the root of that
folder. A class such as <code>com.example.myapp.pages.user.IndexUser</code> or
<code>com.example.myapp.pages.user.UserIndex</code> will have a page name of
<code>user/</code>.</p><p>In previous versions of Tapestry there was also the
conce
pt of a start page configured with the <code><a
href="configuration.html">tapestry.start-page-name</a></code> configuration
symbol (defaults to "start"). If a page with a name as configured with that
symbol exists at the root level, this page is used as the root URL. This has
precedence over an existing Index page. If for example you have a page class
<code>com.example.myapp.pages.Start</code> it will map to
<code>/</code>.</p><div class="confluence-information-macro

Components</h2><p>The distinction between pages and component is very, very
small. The primary difference is the package name:
<em>root</em>.<strong>pages</stron
g>.<em>PageName</em> for pages, and
<em>root</em>.<strong>components</strong>.<em>ComponentType</em> for
components. Conceptually, page components are simply the <em>root
component</em> of a page's component tree.</p><p><em>For Tapestry 4 users:
there was a much greater distinction in Tapestry 4 between pages and
components, which showed up as separate interfaces and a hierarchy of abstract
implementations to extend your classes from.</em></p><h2
id="ComponentClasses-ClassTransformation">Class Transformation</h2><p>Tapestry
uses your class as a starting point. It <em>transforms</em> your class at
runtime. This is necessary for a number of reasons, including to address how
Tapestry shares pages between requests.</p><p>For the most part, these
transformations are both sensible and invisible. In a few limited cases, they
comprise a marginally <a class="external-link"
href="http://www.joelonsoftware.com/printerFriendly/articles/LeakyAbstractions.html";
rel="nofollow">leaky abstracti
on</a> – for instance, the scope restrictions on instance variables
described below – but the programming model in general supports a very
high level of developer productivity.</p><p>Because transformation doesn't
occur until <em>runtime</em>, the build stage of your application is not
affected by the fact that you are creating a Tapestry application. Further,
your classes are absolutely simple POJOs during unit testing.</p><h2
id="ComponentClasses-LiveClassReloading">Live Class Reloading</h2><p>Main
Article: <a href="class-reloading.html">Class Reloading</a></p><p>Component
classes are monitored for changes by the framework. <a
href="class-reloading.html">Classes are reloaded when changed</a>. This allows
you to build your application with a speed approaching that of a scripting
environment, without sacrificing any of the power of the Java
platform.</p><p>And it's fast! You won't even notice that this magic class
reloading has occurred.</p><p>The net result: super
productivity — change your class, see the change instantly. This is
designed to be a blend of the best of scripting environments (such as Python or
Ruby) with all the speed and power of Java backing it up.</p><p>However, class
reloading <em>only</em> applies to component classes (pages, components and
mixins) and, starting in 5.2, Tapestry IOC-based service implementations (with
some restrictions). Other classes, such as service interfaces, entity/model
classes, and other data objects, are loaded by the normal class loader and not
subject to live class reloading.</p><h2
id="ComponentClasses-InstanceVariables">Instance Variables</h2><p>Tapestry
components may have instance variables (unlike Tapestry 4, where you had to use
<em>abstract properties</em>).</p><p>Since release 5.3.2, instance variables
may be protected, or package private (that is, no access modifier). Under
specific circumstances they may even be public (public fields must either be
final, or have the @<a class="e

id="ComponentClasses-TransientInstanceVariables">Transient Instance
Variables</h2><p>Unless an instance variable is decorated with an annotation,
it will be a <em>transient</em> instance variable. This means that its value
resets to its default value at the end of reach request (when the <a
