partial page processing issue 3.0.M3/2011-08-26

[rkrenn]

hi,

since today 3.0.M3-SNAPSHOT has a problem with partial processing, if containers/elements to process are not specified with default values (like process=@this,@parent, ...):

this still works:

Code: Select all

<p:commandButton ajax="true" process="@this" actionListener=... />

but this fails since this morning:

Code: Select all

<p:commandButton ajax="true" process="some_named_element" actionListener=... />

(actionListener is not invoked any more). This does not happenswith the standard example cases, but e.g. if "some_named_element" is somewhere in a <ui:insert>ed xhtml.

i wonder if this is related with https://code.google.com/p/primefaces/so ... ail?r=5366 (Fix for partial state saving disabled.) / https://code.google.com/p/primefaces/is ... id=2437#c0?

Should be;

Code: Select all

<p:commandButton ajax="true" process="@this some_named_element" actionListener=... />

We were adding @this by default in the past, but it was breaking other things so we left it out and reverted back.

Hello Cagatay,

We were adding @this by default in the past, but it was breaking other things so we left it out and reverted back.

What is default if you don't specify "process" attribute in PrimeFaces? JSF impl. has @this as default in f:ajax http://javaserverfaces.java.net/nonav/d ... /ajax.html I think, PrimeFaces has another default. Right? Were there problems here with @this? Can you remember the reason of that? Would it be not better to have @this as default? Otherwise we have to write in > 50% cases process="@this" instead of omit this attribute completely.

thank you very much; applied and works!

edit / oleg's comment: obviously, if you don't specify any "process=" it will use @this as default. only appending @this is mandatory now.

Command components defaults to @all, p:ajax to @this.

[Oleg]

Oh, I meant command components of course. So, ajaxified p:commandButton has @all as default and h:commandButton with p:ajax / f:ajax @this as default? Any reason of @all? @all looks like not ajaxified command component, but ajax="true" is default for all PF command components. That means user expects rather @this than @all I think. I would never use implicity process="@all" for p:commandButton. What do you think?

Is there any problems using <p:commandButton> with components like <p:autocomplete>, or ajaxify events?

For me, this code do not work fine

If I use @all in addItemButton, this do not work too. Idem for @parent, @form and @none.

[sfohart]

I needed using <p:ajax> for all components into html fieldset, and @this in "Adicionar" commandButton...

Is there other solution?
