Struggling implementing ExtendedDataModel and my web service

daleellis1983 Jan 3, 2012 12:42 PM

Hi all,

I have a little application that pulls down some data via a web service. Up until now I have not implemented the data model so just cached all the returned results but I have now enhanced the web service to do pagination, so I thought the easiest part was done but I have spent 2 days not trying to get it working and something is not right. I have been using documentaion from Practical Richfaces 2nd edition and the online example but my scenrio is slightly different and I'm not sure what the issue is.

The main difference from the example I have read is that I have a config driven set of search fields and a search button to load the table. It seems as through the way I make a ajax call is not reloading the model? or something like that as what happens is that when I press search, in the logs I see what I expect to happen, teh data is retreived and data cached but nothing is displayed in the table, although sometimes when I hit a certain combintion, like search then search, then do a sort then data is returned, just baffled at teh moment and would really appriecated some help in understanding where I'm going wrong

Code

1. Re: Struggling implementing ExtendedDataModel and my web service

healeyb Jan 5, 2012 6:59 PM (in response to daleellis1983)
Dale, I've written an abstract base class which theoretically adds a level of abstraction between your code
and the ExtendedDataModel. Like you I read through practical richfaces 2, and this is what I came up with
after some testing.

The idea which should be pretty familiar is to create an instance of an anonymous subclass of RichLazyDataModel,
overriding the getDataList(), getKey() & getTotalCount() methods. There is a comment in the attached code giving a
usage example.

I use this with RF 4.1.0.Final and so far it seems to work ok for me. Of course the problem could well be
unconnected with the way you're implementing ExtendedDataModel, in which case this can only eliminate a
potential cause.

2. Re: Struggling implementing ExtendedDataModel and my web service

Thanks for your reply Brendan,

I managed to get it working 2 days ago with a bit of a bodge and bit of refactoring to make it cleaner, I more or less have the same as your code except I don't cache the row numbers as I retreive the total as part of the web service call and I also check to see if sorting has changed to see if I need to go to refresh the data, sorting and criteria data are passed to my fetch method.

Currently I only have one page that uses paging but I think I will mimic your approach as it makes sense to create a base super class to factor out common parts.

Sorting and the paging buttons work absolutely fine, the only issue I have is that when I do a search the results don't get reflected until a subsquent request, so for a bodge I did this...

        <a4j:commandButton id="searchSubmit" value="${caseBean.searchFieldConfig.button.label}" action="${caseBean.search}"
        style="${caseBean.searchFieldConfig.button.style}"
        onbegin="this.disabled=true"
        oncomplete="#{rich:element('searchSubmitBodge')}.click();"
        render="caseResultsContainer"/>

        <a4j:commandButton id="searchSubmitBodge" action="${caseBean.none}" value="Load" render="caseResultsContainer"
                           oncomplete="#{rich:element('searchSubmit')}.disabled=false; hideIfResultsReturned();" style="display:none;" />

So that is the bodge, I call a action to force a re render of the table straight after the search and that all works fine. I'd love to know how to get that working properly but I'm just happy it's working at the moment.

Cheers,
Dale
