I’m running into trouble with my new document type. I am trying to create a
search UI, and it’s not working properly.
I created a new tab in my new document type, which contains a search prompt.
All my documents have some space set aside for keywords, and the search UI I’m
designing is going to search all documents and return the documents that have
the matching keyword. I go to the tab, type in the keyword I want to search
for, and then I click the “search” button, and then this error appears in the
browser:
/incl/tabs/my_view.xhtml @22,80 value="#{myFileManager.keyword}": Target
Unreachable, identifier 'myFileManager' resolved to null
I have a feeling it relates to the connection between the .xhtml file and my
Bean. Has anyone seen this error before, and how do I solve it?
This was the code for my .xhtml document:
<div xmlns="http://www.w3.org/1999/xhtml";
xmlns:f="http://java.sun.com/jsf/core";
xmlns:h="http://java.sun.com/jsf/html";>
<h2>Searching for documents by keywords</h2>
<h:messages styleClass="errorMessage" />
<h:form>
<h:panelGrid columns="3" styleClass="dataInput"
columnClasses="labelColumn, fieldColumn, fieldColumn">
<h:outputLabel value="Enter a keyword to search for" />
<h:inputText id="theKeyword" value="#{myFileManager.keyword}"
required="true" />
<h:commandButton type="submit" value="Search" action="#
{myFileManager.performSearch}" class="button"/>
<h:message for="theKeyword" styleClass="errorMessage" />
</h:panelGrid>
</h:form>
The code for my Bean is below. Please note the fact that I liberally took
parts of the SearchActionsBean and put them into my class, and I also added in
the search method from the BookManagerBean incase I could use that (I haven't
done so yet, though).
