filtering: java.lang.NullPointerException during using filterMethod under jsp-myfaces. -------------------------------------------------------------------------------------- Key: RF-3901 URL: https://jira.jboss.org/jira/browse/RF-3901 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.2 Environment: ie6, ie7, ff, safari, opera(3.2.2.BETA1) Reporter: Mikhail Vitenkov Assignee: Mikhail Vitenkov Fix For: 3.2.2 Step 1. Add filterMethod method in bean: public boolean filterMethod(Object obj) { Data d = (Data)obj; if(d.getStr0().startsWith(filterInput)) return true; return false; } Step 2. Add filterMethod method for rich:column through the "filterMethod" attribute: <rich:column sortBy="#{data.str0}" sortOrder="#{sortingAndFiltering.sortOrder}" filterBy="#{data.str0}" filterMethod="#{sortingAndFiltering.filterMethod}"> <f:facet name="header"> <h:outputText value="#3" /> </f:facet> <h:outputText value="#{data.str0}"></h:outputText> <f:facet name="footer"> <h:outputText value="#3" /> </f:facet> </rich:column> Step 3. Add input field for "filterInput" value(See Step 1). Step 4. Navigate to the page, contained rich:column described in Step 2.
