Pass URL parameters in sample viewer

AaronNash — Wed, 03 Nov 2010 15:08:10 GMT

There was a previous thread on the old forum to pass search parameters into a url string,
http://forums.esri.com/Thread.asp?c=158&f=2421&t=294907&mc=104#msgid925229
I would like to see if anyone has accomplished this for the new viewer. I have a non-spatial flex application that runs a query on a ArcServer service and returns the results into a datagrid, I then have a button that exports the results into a pdf report. I would like to have another function that takes a value from the datagrid, populates it into a URL string that opens a new browser and zooms to that selected feature.

thanks,
Aaron

Aaron,

As you saw from that post this is not simple... Here are the instructions for all the components that have to be changed in FlexViewer 2.1. Maybe I did not forget anything...

Are there any other items that need to be done if using the enhanced search widget?

Lee,

Yep there is a pretty big difference. I will have to find some time to update for that.

Robert, I have been working through this code and have not been able to get it to work. I can compile with no errors and the ext string will zoom to the extent. But when I try to zoom through a query it does not execute a search through the widget. I have been comparing the provided code to the other thread and you had some additions to the IBaseWidget and BaseWidget, is that code still needed for this build?

thanks

Aaron,

Are you using the standard search widget? The basewidget stuff from the old code is irrelevant now.

Re: Pass URL parameters in sample viewer

AaronNash — Tue, 30 Nov 2010 13:17:46 GMT

I started adding the code into your enhanced search widget and then saw the follow up question from Lee, so i deleted the code and added it into the base search widget included in the sample viewer.

Aaron,

Make sure you have preload="open" in your config.xml for the search widget then. I am pretty sure my instructions text a couple of posts above covers every thing...

Robert,

thanks for replying so quick, I do have the preload set to open. i am going through the code again and everything looks like it is in place. here is a URL to the sample viewer site http://gis.vernon-ct.gov/new_viewer/index.html?MBL=40-0107-00010 you can see the behavior on how it does not search when the link is clicked.

Aaron,

You should probably zip up all three files that were changed and let me look at them.

Re: Pass URL parameters in sample viewer

AaronNash — Tue, 30 Nov 2010 14:57:07 GMT

Attached are the modified files, I appreciate you looking at this

Aaron,

In your MapManager:

       if (result["Parcels.DBO.Parcels.MBL"])
        xPPIN = result.Parcels.DBO.Parcels.MBL;

This is suppose to be the name of the parameter that you are passing in from the url (i.e. MBL)

Change these line to:

       if (result["MBL"])
        xPPIN = result.MBL;

Re: Pass URL parameters in sample viewer

AaronNash — Tue, 30 Nov 2010 18:04:08 GMT

made the changes, no luck. Same behavior

RobertScheitlin__GISP — Tue, 30 Nov 2010 18:57:53 GMT

Aaron,

Do you have the Flash player debuger version? You need to place some break points in your code and debug to see if you get to them.

Re: Pass URL parameters in sample viewer

AaronNash — Wed, 01 Dec 2010 15:36:14 GMT

I had to change somethings on my machine, but I have debugger mode set up. Any suggestions on where i should put break points and what I behavior I should be looking for. I have not run in debugger mode

Aaron,

Here are some steps to take:

This is the most involved but the correct way to specify url parameter values for your apps launch configuration. There are many steps to do this but if you follow then you will have your development environment step in the best possible way to debug and work with your app and flash builder.
I. Download Flash Player Debug version here http://www.adobe.com/support/flashplayer/downloads.html
If you are using IE then choose (for IE)
If you are using FireFox or any other browser as your default then choose (for Netscape compatible browsers).

II. Configure IIS (Assuming you are not using any other web server) virtual directory for your app
a. In IIS choose new virtual directory name it FlexViewer2.1 and point it's path to your bin-debug folder for your flexviewer project.

III. Right click on your app in the project navigator window and choose properties and then Flex Build Path

IV. In the output folder url type your machine name and the virtual directory name you specified in step II.
V. click Run/Debug Settings (back on the left).
VII. choose your app which is likely to be the only thing in that window and then edit
VIII. look towards the bottom of this dialog and un-check use default
IX. add ?MBL=xxxxxxxxx

then I would start by adding a break point in the map manager right under this line

if (xPPIN != ""){

and what you are looking for is when you reach the breakpoint (if you do) does xPPIN have the value that you passed into the URL? From there I would put a breakpoint in the utimerComplete function (first line of that function) and step through the code to see if the id variable is not NaN.

Re: Pass URL parameters in sample viewer

AaronNash — Wed, 01 Dec 2010 16:52:37 GMT

I think I am doing this correctly, I have everything running on my local machine in debug mode in IIS. I added the specified break points and stepped through them, I attached 2 screen shots. At

if (xPPIN != ""){

xPPIN did have a value, I Stepped past that, it went through the event listener and started the timer. Went to

if (!xExt == "")

and then jumped to the bottom of the function

catch (error:Error){}

. At the second break point, function utimerComplete, the id variable was NaN. BTW thanks for all your help

RobertScheitlin__GISP — Wed, 01 Dec 2010 17:01:25 GMT

Aaron,

once you step past your second breakpoint is the id still NaN? If so in your config.xml is your searchwidgets label "Search"?

Re: Pass URL parameters in sample viewer

AaronNash — Wed, 01 Dec 2010 17:27:53 GMT

I have made some progress, It does figure out and populate the id as 8, which is correct. I have followed the process into the search widget's queryPPIN function, it brings over the xPPIN value. When I step forward it jumps to the function onResult totally missing the query.

Re: Pass URL parameters in sample viewer

RobertScheitlin__GISP — Wed, 01 Dec 2010 17:36:17 GMT

Aaron,

You need to place a breakpoint in the queryPPIN function so you can see what the

query.where = expr;

where is equal to.
