SFV 1.3 Pass URL to Search parcels

LeeAllen — Thu, 06 May 2010 14:59:30 GMT

I would like to pass a URL string from our property search page like http://...PRCL_ID=1420303004021000 to the flex app search so that when users click on a link on the property search page, this ID is sent to the app and zooms to the parcel automatically. Is this possible?

I have the search widget setup to search ID's when typed in.

Hi Lee,

Take a look at this forum as well. If I'm understanding what you're looking for correctly we have this working on our site. The forum is quite long, but sprinkled throughout it are all the steps you'll need.

I have followed all of the steps in forum, I think I'm close. After compiling, I get an error in my SiteContainer.mxml (Description Resource Path Location Type
1021: Duplicate function definition. SiteContainer.mxml /Flexviewer1.3/src/com/esri/solutions/flexviewer line 176 Flex Problem)

here is the code in the .mxml file:

public function init():void
   {
    _container = this;
    _lock = true; //make sure only one container is created.

    initLogging();

    //make sure the event bus is ready.
    _containerEventDispatcher = EventBus.getInstance();

    //prepare to show error message
    SiteContainer.addEventListener(AppEvent.APP_ERROR, showError);

    //listen for the config data to be loaded
    SiteContainer.addEventListener(AppEvent.CONFIG_LOADED, config);

    //tell the modules it's on business.
    SiteContainer.dispatch(SiteContainer.CONTAINER_INITIALIZED);
   }

I can post all of .mxml files if necessary.

Thanks for any help!

Hi Lee,

I don't know if this matter or not, but there are a couple of spaces in the code that may have just been how they were copied into the forums.

//listen for the config data to be loaded
SiteContainer.addEventListener(AppEvent.CONFIG_[LOA DED, config);

//tell the modules it's on business.
SiteContainer.dispatch(SiteContainer.CONTAINER_INI TIALIZED);

If that's not in your actual code could you post your entire SiteContainer and I'll take a look at it.

Here is the site container and the mapmanager(just in case you need to take a peek at it) mxml files. Thanks for taking a look. Lee

Hi Lee,

See if this SiteContainer works. I noticed a couple of lines of code that were missing. Hopefully this is all that's missing.

I didn't check the MapManager, but if this doesn't work I'll take a look at that too.

Cory,

I can't get the code to come through with that file (saved and renamed without .zip), could you try again or put code in reply for me to copy?

Thanks!

Cory, thanks. I got everything to compile with no errors, but like many before me, nothing happens when the site runs. I looked at it in firebug, and it is not getting the GET query. The site is http://gis.snco.us/gisviewer. The test URL would be http://gis.snco.us/gisviewer/index.html?PRCL_ID=133647600700000. I have attached the SiteContainer.mxml, MapManager, and Search.mxml.

Thanks for any help!!!

Cheers and happy holidays, I''m out for the weekend.

Try adding

to the

function.

I'm getting an error when exporting release build (which I believe I was getting just before I implemented your code). Obviously it is referring to the custom draw tool, but can't figure out why it is looking for an associated html file.

   See details for more information.
    Flash Builder could not publish the project source: Resource '/Flexviewer1.3/bin-release1/srcview/source/com/esri/draw/CustomDraw.as.html' does not exist.

Hi Lee,

Unless I'm mistaken, There shouldn't be a CustomDraw.as.html file, it should only be CustomDraw.as or Action Script file, not HTML. Try renaming that file with just the .as extension.

Hi,
I was able to get the solution above to work, but how do you display the attributes after the search has been performed. The application zooms-in, but there is nothing in the results window or datagrid? If I use the search widget and type in a parcel or use the graphical tools, the results show up fine, but will not display by passing the parameter via the url.

Thanks,
Frank

Re: SFV 1.3 Pass URL to Search parcels

RobertScheitlin__GISP — Tue, 03 Aug 2010 02:00:23 GMT

Frank,

The zoom in to the parcel is the easy part of the code. if you are not getting the search widget to actually run the query and display the results than there a a half dozen or more things that could be wrong. This is not a very easy thing to setup as there are so many vital steps that have to be done correctly to many different files for this to work. My best suggestion as the developer of the code is to care fully look at each post in the original thread and check and double check that you have completed all of the steps. There are instruction scattered all over the place in the original thread.

Re: SFV 1.3 Pass URL to Search parcels

FrankTrevino — Tue, 03 Aug 2010 12:52:40 GMT

Thanks Robert. I was able to find a smal piece of code in the previous threads that I was missing as part of my query function in the SearchWidet. I added a 'for loop' and I am now getting back the query fields as part of my results.

Is there a way to add the result to the floating Datagrid? I am tweaking the code a bit to add the logic, but I keep getting the mesg "No Datagrid configured......."

Looks like myfloatdg is not getting initialized

   if (myfloatdg){
        if(myfloatdg.datagrid.dataProvider)
         myfloatdg.datagrid.dataProvider.removeAll();
        myfloatdg.csvName = _csvName;
        myfloatdg.dgColumns = gridFields;
        myfloatdg.dgHyperColumns = gridHyperFields;
        myfloatdg.showHyperAlias = gridHyperFieldsAlias;
        myfloatdg.dProvider = featureSet.attributes;
        myfloatdg.graphicslayer = graphicsLayer;
        myfloatdg.zoomScale = zoomScale;
        myfloatdg.ownerWidget = sWidget;
       }

FrankTrevino — Wed, 04 Aug 2010 17:28:50 GMT

Hi,
I was wondering if there is a way to furthur customize the passing of the URL to also search for an address using a geocode service, much the same way the parcels is being passed and uses the search widget. If an application appends an address to the url, is it possible to call the "Locate Widget" and perform the address search. I've tried to incorporate some of the logic used in these threads, but not much luck.

I got it to work using the searcgwidget and just point to the address layer instead of parcels, but I would like use the geocode service and display the address matches. Is this something that can be configured.
