Search and Promote OOTB component NullPointerException

[http://stackoverflow.com/questions/42446673/search-and-promote-null-pointer]

 

Using the provided OOTB Search & Promote components with an S&P service the following error is thrown when I try and search:

GET /content/Search/Results.html HTTP/1.1] org.apache.commons.httpclient.HttpMethodBaseGoing to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended.GET /content/Search/Results.html HTTP/1.1] org.apache.sling.engine.impl.SlingRequestProcessorImpl service:Uncaught SlingExceptionjava.lang.NullPointerException: null at com.day.cq.searchpromote.xml.result.Pagination.getResultPages(Pagination.java:69)

So there's a null in the following code on the getResultPages call, in the results component.

 Pagination pagination = search.getPagination();if(pagination != null) {totalPages = pagination.getTotalPages();for (ResultPage resultPage : pagination.getResultPages()) {if (resultPage.isSelected()) {currentPageNumber = resultPage.getPosition();}}}

Does anyone know why this might be null? Even if I have no valid search results I'm assuming this should still provide me with a valid view of zero results.

I worked with S&P where it used to return JSON and it was client side driven project.

But I would say, if you add null checks where you are getting this error. It should solve the issue.

S&P might remove inner array when there are no results.

I have worked with S&P for AEM projects, Can you share the response you get when there are no result?

Thanks

Hi edubey, 

Thanks for getting back to me.

There is no response because it breaks on an internal server error.
