I am having a little trouble with my web-app, essentially I keep getting an warning message:
INFO: Cannot find component with identifier "formName" in view.
I know why this is happening, but I just need to determine if their is a fix/better solution.
Basically I have a master template file that contains a number of <p:dialog>
components, which have various CRUD capabilities. When a user interacts with these components I use the inbuilt primefaces 'update' function to ajaxically update the various forms/components in the <ui:defined>
page(s). However, because of the layout the JSF web-app (ie Master template and ui:defined web pages) and the fact that I have defined these components in the Master template file, it means that the update-able forms/components are not necessarily in the current view and throwing the warning message above.
For Example:
If I had my Master Template file: master.xhtml with a component called < p:dialog id="componentA" />
. And then I had page1.xhtml with a <h:form id=page1Form/>
and similarly I have a page2.xhtml with <h:form id=page2Form/>
, which both contained information provided by a sessionscoped backing bean, what would be the best method to ensure that these forms are updated if a CRUD operation occurs using componentA? At the moment I am simply using < p:dialog id="componentA" update="page1Form, page2Form" />
but because only page1 or page2 are is in the view, Tomcat spits out the above message. So is it possible to dynamically specify the forms/components to update dependant on the page I am on, or do I have to specify componentA on every <ui:define>
page (which would be lots of repeating html/code and not particularly manageable) or is there a method to update all forms/components in the current view? Or is what I am doing correct and I should just turn off development mode in my web.xml to cease the messages?
Cheers

Just to confirm, if anyone stumbles upon this thread. I managed to fix my above problem by using the <ui:param name="paramName" value:"a value"/>
value.
Essentially in your master template file specify your component like you would ie
<p:commandButton value="Submit" action="#{someBean.doSomeStuff()}"
update="#{paramName}" />
Then in your <ui:composition>
page you simply state param name and its value:
<ui:param name="paramName" value="someForm someOtherForm"/>
jobs a goodun!
