Leonardo Uribe reopened TOMAHAWK-1504: -------------------------------------- I'll reopen this one to try to find an alternative to Martin's suggestion. > Update 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 > Fix For: 1.1.10-SNAPSHOT > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
