commandLink does not work within a dataTable
Hi,
I have got a problem with the commandLink-components within a dataTable. The
connected actionListener-method is never executed and the same view is
displayed without any changes. It is a very weird problem, because a quite
similar view with commandLinks in a dataTable does work(!) and this one not!! I
could not find any reason why it is not working:
t:dataTable id=articletypesByProductlevel var=articletyp ...
h:column
f:facet name=header
h:outputText value=Bezeichnung/
/f:facet
h:commandLink id=chooseArticletypeLnk
actionListener=#{createArticleBean.chooseArticletype}
h:outputText id=itemtext
value=#{articletyp.itemtext}/
/h:commandLink
h:inputHidden id=id value=#{articletyp.id}/
/h:column
...
t:datatable
The generated Html-Code:
a href=#
onclick=clear_createArticleForm();document.forms['createArticleForm'].elements['autoScroll'].value=getScrolling();
document.forms['createArticleForm'].elements['createArticleForm:_link_hidden_'].value='createArticleForm:articletypesByProductlevel_
0:chooseArticletypeLnk';
if(document.forms['createArticleForm'].onsubmit){if(document.forms['createArticleForm'].onsubmit())
document.forms['createArticleForm'].submit();}else{document.forms['createArticleForm'].submit();}return
false;
id=createArticleForm:articletypesByProductlevel_0:chooseArticletypeLnk
span
id=createArticleForm:articletypesByProductlevel_0:itemtextRollenfalz/span/a
input type=hidden id=createArticleForm:articletypesByProductlevel_0:id
name=createArticleForm:articletypesByProductlevel_0:id value=4 /
Even if the actionListener attribute of the commandLink-component contains a
value that does not map to a backing bean method, there is no error thrown.
Is this known problem?
Has anyone the same problem?
Is there a solution or should I simply not use a commandLink within a dataTable?

Ünsal

Hi Geeta,
Thank you for your answer, but could you explain what
thelist has to do with my problem? I suppose that you mean with
"list"the value-attribute of the dataTable-component, which is in my case
a Collection of model-objects.
Regards,
Ünsal

t:datatable Hi Unsal, you
have two choices (that I know of!): either place your list in session scope or
use t:saveState for your list. Regards, Geeta

Hi Geeta, thank you very much, the problem is solved. Your guess was absolutely correct. After I taken care that the collection is available after the Restore View phase everything works fine.

Well Ünsal, I am not at all an expert in JSf but here's what I believe happens (and I hope somebody will correct me if I am wrong or incomplete): if your list of objects is only in request scope then your page will be displayed ok. However after the Restore View phase, your collection will be thrown away. So when you click on an entry in your table, this action is processed as part of the "Process Events" phase as part of the *next* request (so *after* the collection has been gced). Which is why you need to save your collection either in session scope or via t:saveState. I suppose that you mean with "list" the value-attribute of the dataTable-component, which is in my case a Collection of model-objects. Yes, this is what i mean. Regards, Ünsal Regards, Geeta
