It's also possible to use JSF EL expression as a value of the reRenderĪttribute. The following example shows the difference in approaches (both Therefore, you can define how fast the component is found mentioning Each other step is used if the previous step is As can you see, theĪlgorithm presumes several steps. "reRender" uses UIComponent.findComponent() algorithm (with some additionalĮxceptions) to find the component in the component tree. As you see, it's not difficult to update multipleĮlements on the page, only list their IDs as the value of "reRender". In thisĬase, the only part of the page to update is the tag because its ID value matches to the value of "reRender" attribute. The value of "reRender" attribute of the tag defines which part(s) of your page is (are) to be updated. "reRender" attribute is an id of the JSF component or an id list. That should be updated as a response on Ajax interaction. The attribute allows to point to area(s) on a page However, their usage allows to tune the required Ajax behavior very smoothly. You can start working with RichFaces without knowing the usage of these attribute. Most of the attributes have default values. Have these attributes for a similar purpose. Also, most RichFaces components with built-in Ajax support Of the component tree, calls its own renderer and put the result into the FacesĪjax attributes are common for Ajax components such as, ,, , and so on. Render Response Phase RichFaces framework makes a traversal RichFaces components uses their own renderers. The RichFaces ViewHandler puts itself in front of the Lot's of unexpected effects can be produced by an incorrect HTML code. Any necessary XMLĬorrections are automatically made by the XML filter on the server, but Without skipping any required elements or attributes. Thus, create only a strict standards-compliant code for HTML and XHTML, XML bypasses most validations and the corrections that might be made in aīrowser. Recommended to place messages in the "AjaxOutput" component (as no messages is also a message).ĭon't use for self-rendered containers, since this component is transient andĪjax requests are made by XMLHTTPRequest functions in XML format, but this If you'd like to append any code to a page, put inĪ placeholder for it (any empty element). For successful updates, an element with the same ID as in the response Identifying User RolesĪny Ajax framework should not append or delete, but only replace elements on Client-side Script for Extended Skinning Support 5.11.10.
