Tag Library

From AgileApps Support Wiki

To make coding of Pages easier, the AgileApps Cloud platform provides a set of custom JSP tags. Similar to JSTL (Java Standard Tag Library), these tags make development of pages easier and make a clear separation between View, business logic (Controller) and Model of a use case. Learn more: MVC (Model-View-Controller). To successfully use these tags, include a taglib directive in any Page used to build the Site.

taglib Directive Syntax
<%@taglib prefix="lj" uri="/LJTagLib"%>
Available Tag Types
HTML Tags
Used to map to different HTML elements. These can be used standalone or can be enclosed within DetailData and Form tags. These tags Handle the View Part.
Platform-specific Action Tags
Used to map to server-side actions, and handle the Business Logic/Controller Part. Learn more: Included Server-Side Actions
Platform-specific Data Tags
Used to retrieve data from the server. These tags handle the Model Part.
Miscellaneous tags
Utility Tags to provide Utility.

Form Tag

Used to render the HTML form element.

Attributes
In addition to Common Attributes for HTML Tags, the following attributes are available:
Tag Type Description
action String One of add/update/delete
controller String Specifies which controller will handle this form. If the value is "Platform", Platform will handle the action, otherwise it will assume that it is a user written controller class and forward the request to the controller class
object String Object name or id to take the action on

Include Tag

This tag has two uses:

  • It is used in a Site Template (a wrapper page) to indicate where to include the content of the page being visited.
  • It is used to include another JSP page stored on the platform. In that case, it can help to organize your pages. For example, common libraries can be declared on a single page--say, common.jsp. If that page is included everywhere, a new library can be added to every page simply by declaring in the common page.

Action Tags

These tags directly map to various platform actions specified in the Actions section. These action tags render an HTML form element.

Common Attributes for Action Tags

All the action tags have some common attributes.

Common Attributes for Action Tags
Attribute Type Description

preControllerMethod String Method of the class identified by preController, that is executed before the controller is executed. Useful in validations or some pre actions when controller is Platform.
prefill Boolean Specifies whether the values should be prefilled for the form elements within this form. Prefill logic first looks at the HttpServletRequest.getParameter("form element"), if the value is present it will render it from there, otherwise it will take it from the value attribute of the form element. This is specifically used for error handling.

Login and Registration Tags

Login tags and Registration tags have slightly different behavior:

  • Registration tags - Allow the site user to register and login using a remote ID, like Facebook. When site users are already registered, they are automatically logged in. With this option, anyone can become a site user, and the only information available to the Site are the details captured in the remote registration process (at Facebook, for example).
  • Login Tags - Allow the user to login using a remote ID, but require them to have registered with the site to do so. You can use that registration process to a) capture additional information from the user and/or, b) restrict access in some way (for example, to restrict access to an otherwise-public company payroll site).

Typically, you will choose to use either registration tags or login tags. But whichever style you choose, you will typically provide site users with multiple options so they can choose how they want to log in.

Notepad.png

Note:
For Login tags to work, the user ID at the site must be identical to the remote user ID. One way to do that is simply to require the user to enter their ID, and trust that it will match. (Typically, it will, since a user's email address is the most common form of ID. Another, more "bulletproof" mechanism is to check to see if users are registered when they login. If they aren't, send them to the registration page with the user ID pre-filled. That mechanism is more complex, but doesn't depend on users' typing ability or memory.

Action Tag Description Syntax
Facebook Registration Tag Let a site user register and login using their Facebook ID <lj:facebookregister onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." />
Facebook Login Tag Let a site user login using their Facebook ID, but require site registration <lj:facebooklogin onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." />
Login Tag Renders an HTML form element whose action attribute is assigned to the Login action <lj:login name="loginForm" onError="pages/login.jsp" onSuccess="pages/home.jsp" method="POST" id="loginForm">
Logout Tag Renders a URL which points to the Logout action <a href="<lj:logout />">Logout</a>
Register Tag Renders an HTML form element whose action attribute is assigned to the Register User action <lj:register name="" onError="pages/register.jsp" onSuccess="pages/home.jsp" prefill="true" method="POST">
Note for Self-Hosted Installations of the Platform
In a self hosted installation of the Platform, additional setup is required to support registration and authentication using Facebook. The Administrator needs to set up a Facebook Application and configure details about the application in the platform.
To set up a Facebook Application:
  1. Go to https://developers.facebook.com and create a new Application.
  2. Modify the Application to set the App Domain to point to your domain.
  3. Specify the Site URL in "Website with Facebook Login", so it points to your Domain URL
  4. Note the App ID and the App Secret
To configure the platform:
Update the Facebook App ID and the App Secret in the Platform using SQL:
UPDATE relationals.NETWORK_GLOBAL_PROPERTIES
SET facebook_app_id = 'facebook App ID' , facebook_app_secret='App Secret';
Facebook Registration Tag

Generates a button that allows a site user to register and login using their Facebook ID. Users who are already registered with the Site are simply logged in.

Example
<%@taglib prefix="lj" uri="/LJTagLib"%>

<a href="<lj:facebookregister onError="pages/home.jsp"  
   onSuccess="pages/ticketList.jsp?fieldList=number,type,subject&sortBy=number&sortOrder=desc&page=0&pageSize=25" />" 
> Login using Facebook</a>
Facebook Login Tag

Generates a button that allows a site user to login using their Facebook ID, but only if they are a registered site user.

Requirement
  • The Site user's username must be the same as their Facebook Email address.
Example
<%@taglib prefix="lj" uri="/LJTagLib"%>

<a href="<lj:facebooklogin onError="pages/home.jsp" 
  onSuccess="pages/ticketList.jsp?fieldList=number,type,subject&sortBy=number&sortOrder=desc&page=0&pageSize=25" />"

Data Tags

Platform specific Data Tags. These map to the Java APIs getRecord (for getting a single record by Id) and searchRecords (for getting a collection of records for a search criteria, with paging support) calls. These tags have some common attributes that are specified below.

Common attributes for data tags

Attribute Type Description
object String id or name of the user defined object
fieldList String A comma-separated list with the names of fields to retrieve.
controller String If value is "Platform", platform will retrieve the values in a data structure. Any other value will be treated as a user written controller class.
controllerMethod String The controller method to execute. (Required when using a custom controller.)
name String Name of the HTML form element which is rendered as a result of this tag.
onError String Relative URL to execute on error of the operation.
onSuccess String Relative URL to execute on success of the operation.
prefill Boolean Specifies whether the values should be prefilled for the form elements within this form. Prefill logic first looks at the HttpServletRequest.getParameter("form element"). If the value is present it will render it from there, otherwise it will take it from the value attribute of the form element. This is specifically used for error handling.
recordVariable String PageContext variable name. The result of the execution of controller (Platform/User Written) is returned as this PageContext variable. In case of Platform controller, the result object is always an instance of Result Class from Java API.
arg1 - arg10 String 10 Custom arguments that you can pass from the JSP to the controller. Especially useful when you are handling the data retrieval part using custom Controllers.
