commandLink not working: FaceTrace
I have a page where the commandLink isn't triggering the associated
actionListener. The link on the page is identical to the link on another
similar page. They are just using different managed beans.
<t:dataTable var="category"
binding="#{SubCategoryAdminBean.categoryData}"
value="#{SubCategoryAdminBean.categories}">
<t:column>
<t:commandLink id="editCatLink"
actionListener="#{
SubCategoryAdminBean.editCategory}">
<t:outputText value="#{category.categoryName}"
/>
<t:updateActionListener
property="#{
SubCategoryAdminBean.currentCategory}"
value="#{category}" />
</t:commandLink>
</t:column>
</t:dataTable>
I started using FacesTrace to see if I could see any useful information.
And what I've discovered is that when processing the page that works I get
the following key/value:
categoryAdminForm:_link_hidden_ --
categoryAdminForm:_idJsp15:1:_idJsp18
However, when I click the link on the page that doesn't work I get
categoryAdminForm:_link_hidden_ --
No value. Problem is, I have no clue what that tells me. Anyone?
Thanks.

I added preserveDataModel="true" to my dataTable and it seems to be working
for now.

Has anyone had a chance to look at this by any chance? I still cannot find
a way to resolve this.
Thanks.

Re: commandLink not working: FaceTrace
Posted by Gregg Bolinger <gd...@gmail.com>.
I think I might know what is going on. It just hit me. When the page is
first loaded, the dataTable is empty. I populate it after I select a
category from the dropdown and click the ok button.
Now, how do I resolve that if that is truly the case?

Re: commandLink not working: FaceTrace
Posted by Gregg Bolinger <gd...@gmail.com>.
To add another piece to the puzzle, I placed a commandLink with a different
ID and the same actionListener outside othe dataTable, and it triggers the
actionListener method just fine.
Thanks.

Re: commandLink not working: FaceTrace
Posted by Gregg Bolinger <gd...@gmail.com>.
Let me deliver this problem a bit differently. I apologize in advance for
the long bit of code I am about to post. I've stripped the page of
everything except what is causing the problem and also stripped down the
managed bean to just support the page.
The commandLinks arren't triggering the actionListener. I am hoping a fresh
set of eyes will be able to clue me in to why. Hopefully it is something
simple. Putting the managed bean in session scope allows everything to
work. But when in request scope, it doesn't work.
