JSF 2 provides queue mechanism out-of the box already. And RichFaces que= ue just provides some additional customizations to improve the queue usability and allow to = tune your performance while using Ajax as much as possible.

The only big difference which the developers who used queue in 3.3.x sho= uld remember: as JSF 2 already provides single queue and not allows to have more than one= queue instance(currently) you can't really fire concurrent requests anymore. So the queue in RF now n= ot actually defines = logical queue but just a component for defining queueing options.

Here you could explore additional optimization parameters of the queue a= nd learn how they = influence Ajax requests. This example is a good start to learn about Ajax r= equests = flood protection.

Pay attention to next point in the example:

  • Setting request delay to greater value reduces the greatly requests cou= nt on fast typing. (More similar requests are combined in the result)
Also pay your attention to the queue definition. Such definition (inside so= me form without a name) means that the queue options becomes global for the= form. = = +id: j_idt70 type: javax.faces.component.UINamingContainer(a)1a3f178 +id: j_id7 type: javax.faces.component.UIPanel(a)d7a9c9 +id: j_idt43 type: = =

Queue could be defined as

  • Default for view. In this case - the parameters will be use= d for all = the Ajax requests in view(if not redefined). In order to define such queue= - just place = a4j:queu outside of any forms without defining name
  • Default for form. Similar to view-scoped but should be defiend= in some form without defining name
  • Referenced from ajax behaviors/components. Queue should be def= ined with name and referenced using attachQueue tag(see corresponding sampl= e).

JSF 2 provides queue mechanism out-of the box already. And RichFaces q= ueue just provides > some additional customizations to improve the queue usability and allow t= o tune your > performance while using Ajax as much as possible.

>

The only big difference which the developers who used queue in 3.3.x s= hould remember: > as JSF 2 already provides single queue and not allows to have more than o= ne queue instance(currently) > you can't really fire concurrent requests anymore. So the queue in RF now= not actually defines = > logical queue but just a component for defining queueing options. >

>

Here you could explore additional optimization parameters of the queue= and learn how they = > influence Ajax requests. This example is a good start to learn about Ajax= requests = > flood protection.

>

Pay attention to next point in the example:

>
    >
  • Setting request delay to greater value reduces the greatly requests c= ount on fast typing. (More similar requests are combined in the result)
    • >
> Also pay your attention to the queue definition. Such definition (inside = some form without a name) means that the queue options becomes global for t= he form. = > = > +id: j_idt70 > type: javax.faces.component.UINamingContainer(a)1a3f178 > +id: j_id7 > type: javax.faces.component.UIPanel(a)d7a9c9 > +id: j_idt43 > type: = > = >

Queue could be defined as

>
  • Default for view. In this case - the parameters will be u= sed for all = > the Ajax requests in view(if not redefined). In order to define such que= ue - just place = > a4j:queu outside of any forms without defining name
    • >
  • Default for form. Similar to view-scoped but should be defie= nd in some form without defining name
    • >
  • Referenced from ajax behaviors/components. Queue should be d= efined with name and referenced using attachQueue tag(see corresponding sam= ple).
