Hi. I want to make list filtering.
On the page i have some dataTable like
| <rich:dataTable var="action" value="#{actionList.resultList}"
| rendered="#{not empty
actionList}"
|
rowClasses="rvgRowOne,rvgRowTwo" id="actionTable">
|
For filtering i have selectOneRadio and commandButton like
| <h:selectOneRadio value="#{actionManager.actionFilter}">
| <s:convertEnum />
| <s:enumItem enumValue="ALL" label="All" />
| <s:enumItem enumValue="SENT" label="Sent" />
| <s:enumItem enumValue="NOT_SENT" label="Not sent" />
| </h:selectOneRadio>
| <h:commandButton
action="#{actionManager.filterActions}" value="Filter"/>
|
For getting the list of actions i use entity query
| @Name("actionList")
| public class ActionQuery extends EntityQuery {
|
| private static final long serialVersionUID = 4880758385999261380L;
|
| private static final String[] RESTRICTIONS_ALL = { "" };
| private static final String[] RESTRICTIONS_SENT = { "a.sent == 1" };
| private static final String[] RESTRICTIONS_NOT_SENT = { "a.sent == 0" };
|
| @Logger private Log log;
|
| @In(required=false)
| private ActionListFilter actionFilter;
|
| @In
| private ActionManager actionManager;
|
| @Override
| public String getEjbql() {
| return "select a from Action a";
| }
|
| public List<String> getRestrictions() {
| log.debug("filter bean: #0",actionManager.getActionFilter());
| log.debug("actionFilter: #0",actionFilter);
| if (actionFilter== null || actionFilter.equals(ActionListFilter
.ALL)){
| return new ArrayList<String>(0);
| }
| else if (actionFilter.equals(ActionListFilter .SENT)){
| return Arrays.asList(RESTRICTIONS_SENT);
| }
| else if (actionFilter.equals(ActionListFilter .NOT_SENT)){
| return Arrays.asList(RESTRICTIONS_NOT_SENT);
| }
|
|
| return new ArrayList<String>(0);
|
| }
|
|
|
| }
|
So as you can see above i building the restrictions according to option
selected by user on the form. The problem is that the line
| log.debug("actionFilter: #0",actionFilter);
|
return null, but later on the action the filter is not null (see bottom)
So the query is executed before my bean method.
I decided to get the value directly from bean but it is null.
Here are the logs
| 17:29:03,250 DEBUG [ActionQuery ] filter bean: null
| 17:29:03,250 DEBUG [ActionQuery ] actionfilter: null
| 17:29:03,250 DEBUG [ActionQuery ] filter bean: null
| 17:29:03,250 DEBUG [ActionQuery ] actionfilter: null
| 17:29:03,281 DEBUG [ActionManagerBean] actionfilter: SENT
|
For me the query is executed before form params gets updated.
In bean the value is correct.
Is this possible to create sth like this without using @Factory methods ??
(beacuse i this it should work in Factory... but may also not work)...
Anyone had similar problem or maybe know the solution
