Question: t:autoScroll is a client-behaviour, and a normal tag, right? So I will just have to add it once to a page if I use Mojarra, right? nice! best regards, MartinUpdate autoscroll feature to JSF 2 ---------------------------------- Key: TOMAHAWK-1504 URL: https://issues.apache.org/jira/browse/TOMAHAWK-1504 Project: MyFaces Tomahawk Issue Type: Improvement Components: JSF2 Affects Versions: 1.1.9 Reporter: Leonardo Uribe Assignee: Leonardo Uribe Attachments: TOMAHAWK-1504-1.patch In jsf 1.1. and 1.2, autoscroll behavior had the following problems: - It is myfaces specific feature, because requires add some code on renderers. In ri it will not work - It only works for h:commandXXX and t:commandXXX components, so if you use trinidad (override h:commandXXX renderers) it will not work. - Since it requires render some javascript at the end of<body> tag, it requires use DefaultAddResource or<t:documentBody> With jsf 2.0 we have the chance to get rid all this problems and make this feature work with other libraries. First a short review about this feature. To make it work, it requires the following points: - Render an<input type="hidden" name="autoScroll" /> that will contain the position on the page (x,y) - Render a function called getScrolling() ant the end of the page that calculate the value and optionally render the command that scroll. - Render the script on each link to call getScrolling() function and assign its value to the hidden field (using oamSetHiddenInput). The idea include add the following code: - Create a new client behavior tag called t:autoscroll that adds the script required on each "command" component. - Create a new component that just render the hidden field. It will be added as a component resource. - Create a new component that render autoScroll script. It will be added as a component resource. - Add some code on ResourceViewHandler, to add the two previous components to the component tree as transient each time the view is rendered, but only if org.apache.myfaces.AUTO_SCROLL web param is true or t:autoscroll is used on the current page. Now, the proposal will work in following scenarios like this: - org.apache.myfaces.AUTO_SCROLL is enabled, myfaces core is used, so all h:commandXXX and t:commandXXX works like in jsf 1.1 and jsf 1.2. - org.apache.myfaces.AUTO_SCROLL is disabled and myfaces core is used, hidden field and script will be added only if t:autoscroll is used. By default, h:commandXXX and t:commandXXX will not have autoscroll script, so t:autoscroll is required to add this script. - RI (Mojarra) is used, hidden field and script will be added only if t:autoscroll is used. By default, h:commandXXX and t:commandXXX will not have autoscroll script, so t:autoscroll is required to add this script.
