I have a commandLink inside a dataTable as below:

<h:column>
    <h:commandLink action="#{pc_jlReport.JoinerleaveReportViewButton}">
        <img src="<%=request.getContextPath()%>/theme/default/images/view.png" alt="" title="" border="0" />
        <f:param name="JLReportId" value="#{JLReport.idJoinerLeaver}"></f:param>
    </h:commandLink>
</h:column>

It should invoke this method:

public String JoinerleaveReportViewButton() {
    try {
        jlr = JoinerLeaverReportManager.getInstance().JoinerleaveReportViewButton(new Long(getRequestParam("JLReportId").toString()));
        return Constants.AVIEW;
    } catch (Exception e) {
        e.printStackTrace();
        return Constants.FAILURE;
    }
}

But it is not invoked. How is this caused and how can I solve it?

does `Constants.AVIEW` return *aview* ? Have you confirmed that `Constants.AVIEW` is returned and not `Constants.FAILURE` ? Is there any exception ? Is this path really correct : `/admin/report/ResultofJoinerLeaverReport.jsp` ? Have you tried to put a print in your method to make sure it is even reached ? – Jean-François Savard May 25 '15 at 16:33
acctually the problem is that on commandLink action it is not going to pagecontroller function i checked it by System.out.println("hello"); but that didn't got printed mean commandLink is not moving to pageController – May 25 '15 at 16:42
Is your commandLink in an `h:form` ? – Jean-François Savard May 25 '15 at 16:44
yes it is between – May 25 '15 at 16:47
Are you sure you refer to the correct bean ? `pc_jlReport` or `JLReport` ? Have you verified that they are correctly managed/named ? – Jean-François Savard May 25 '15 at 16:49
yes i'm sure through same bean i'm generating report! – May 25 '15 at 16:50

and that commandButton function properly ? – Jean-François Savard May 25 '15 at 16:51
Perhaps you have nested form (that could also be caused by inclusion, hard to say without seeing your code) ? – Jean-François Savard May 25 '15 at 16:52
yes! it is working working properly – May 25 '15 at 16:52
I see that your link is in a column, is the column inside a `dataTable` or `ui:repeat` or any other iterable ? – Jean-François Savard May 25 '15 at 16:55
i'm not using nested forms!! – May 25 '15 at 16:59
What about iterable components ? – Jean-François Savard May 25 '15 at 16:59
i believe there is no issue with iterable components, i'm using the same code in another page and jsp but for different report(database values) which is correctly working there!!! – May 25 '15 at 17:05
If really it is the same code, then try doing a clean and build on your project. Perhaps the new faces-config.xml was not deployed. – Jean-François Savard May 25 '15 at 17:09
1

i cleaned and rebuilt project almost 30-40 time :D – May 25 '15 at 17:11
Argh, maybe there is any rendered attributes on parent components that could have evaluated to false during previous JSF execution phase ? – Jean-François Savard May 25 '15 at 17:12
You might also want to check the JS console, I've already experienced a case where jsf's js were not properly loaded which was causing an un-triggered action. – Jean-François Savard May 25 '15 at 17:14
believe me there is non :v – May 25 '15 at 17:14
that's the issue each and everything is fine i checked each and everything more than 30 times but found nothing worng!! still having same issue just at two locations and on remaining location same code is working fine! – May 25 '15 at 17:16
that might be a problem tell me how can i check JS console! – May 25 '15 at 17:17
Have you declared `` at the top of your class ? even if it is empty, it is needed for jsf's js to load. – Jean-François Savard May 25 '15 at 17:17
To check the console on Chrome, right click in page , click on inspect element then click on the las tab (console). – Jean-François Savard May 25 '15 at 17:18
lol yea i did that obviously :p – May 25 '15 at 17:18
ohh that one yes i checked that but i found no error there! – May 25 '15 at 17:19
Then I would try to put the commandLink outside of it parent component (outside of any iterable) just to see if it works there. – Jean-François Savard May 25 '15 at 17:22
