Enhanced Search Widget for FlexViewer 2.1

RobertScheitlin__GISP

All Here is my next widget in the FlexViewer 2.1 series

Special thanks to Erwan Caradec for contributing to this code.

The Enhanced Search Widget extends the standard search widget with a floating data grid and a new spatial query w/buffering.

Robert,
I have downloaded the latest Enhanced Search Widget a couple of days ago and it works fine. Our code base is still pre-Flex Viewer 2.4. I am not sure we should over-write the code base without having to overwrite some of the custom .mxml changes we have done.
With that said, we need to have the Grid to not show any links if the data is null. Now, I have deployed the latest Enhanced Search Widget to the pre SFV 2.4 code base but we still have the problem of Grid showing the links even if there are null values.
For example:
<field name="LEASES" alias="Leases" hyperlinkgridfield="true" hyperlinkaliastext="View Leases" linkprefix="http://pathtotheserver/" linksuffix="" gridfieldonly="false"/>

I suspect it is the linkprefix which is making even null values to appear non-null in the Grid?
Any idea as to how to fix that?
Thanks!

I think around line #620 of the SearchWidgetDGFloat.mxml there is the code which needs to be modified to disable links for null values.

if(attributes[hypercols.field] != "" && attributes[hypercols.field] != " "){
var pre:String = (hypercols.pre == "NA") ? "" : hypercols.pre;
var suf:String = (hypercols.suf == "NA") ? "" : hypercols.suf;
attributes[hypercols.field] = String(pre + attributes[hypercols.field] + suf);
}

IrfanClemsonUser

Never mind. I think I have this problem fixed by modifying the above code a bit:

if (attributes[hypercols.field]) {
        if (attributes[hypercols.valueOf()] != null) {
        attributes[hypercols.field] = String(pre + attributes[hypercols.field] + suf);
        }
       }
       else {
        attributes[hypercols.field] = "";
       }

RobertScheitlin__GISP

Meengla,

I don't think your code is working as you are expecting it is. I was searching for a blank string or empty string but you were right I was not handling a null value. Here is the code to handle all of those:

                        if(attributes[hypercols.field] != "" && attributes[hypercols.field] != " " && attributes[hypercols.field] != null){
                            var pre:String = (hypercols.pre == "NA") ? "" : hypercols.pre;
                            var suf:String = (hypercols.suf == "NA") ? "" : hypercols.suf;
                            attributes[hypercols.field] = String(pre + attributes[hypercols.field] + suf);
                        }

This code will be is the next hot-fix release.

Thanks for the bug report.

IrfanClemsonUser

Robert,
Thanks for your help. But I think the fix I applied in my code below handles 'null' just fine.
Great widget, btw!
Meengla

RobertScheitlin__GISP

Meengla,

Glad you have it working. Just so you should know this line of code is not a valid check for the value of the hyperlink column being null after the first iteration through the loop:

attributes[hypercols.valueOf()] != null

Basically you are getting the value of the object in the hypercols array collection at i, and it will always be an object.

hypercols.addItem({field: cArr[0], name: cArr[1], alias: cArr[2], pre: cArr[3], suf: cArr[4]});

IrfanClemsonUser

Robert, I had already tried the following line:

if(attributes[hypercols.field] != "" && attributes[hypercols.field] != " " && attributes[hypercols.field] != null){

but found out that null values were indeed passing through (meaning, not caught in the 'IF' statement); and then I sometime saw error about 'reference to null' object which meant that attributes[hypercols.field object was null when I tried to gets its 'valueOf()' property. And hence I ended up with my code above. So far I don't see any problem with my code: All null values are caught now and don't show up in the grid.

Thanks for your help again.

RobertScheitlin__GISP

Meengla,

I want to be sure that I get this fixed properly for my next release, so If you don't mind I have some more questions. Can you share your SearchWidget.xml so I can attempt to understand why you sometime saw an error about 'reference to null'. I have been able to trap null values and empty strings and " " strings using the code I posted. So I am curious why it is not working for you, what is the difference between my tests and what you are testing is what I want to understand. If you don't have any more time to spend on this I understand.

IrfanClemsonUser

Robert,
Sure. I can send away my SearchWidget.xml file right away--but it will have to be private. So please figure out a way to share that file? May be you can send me a private message with your email in it?
Sorry for the hassle.
Thanks,
Meengla

Good afternoon Robert.
First of let me say that your widget are great. I use the enhanced Search widget the most. In comparing the standard search widget to the enhanced search widget I notice that the standard search widget has added the variable "useUTC' to the msToDate function. My question is will you be updating msToDate function to include the useUTC function in the enhanced search widget.

RobertScheitlin__GISP

Gladwin,

Sure, I added it to the next release and updated the Enhanced Search Widget XML Configuration.pdf to explain what it does and how to use it.

Thanks for pointing that one out.

GladwinHenry

Thank you for your quick response.. Keep up the great work on your widgets

Robert,

I was trying to search the forums for this, but haven't found it. I have implemented 2.4 eSearch and passing URL parameter. Upon Searching, it finds the feature, but doesn't zoom to it. Is there something else I need to do. Also, I'm looking for the spot in the code to replace "search" with another variable, can you point me to that?

Thanks for all your help, so much easier than when we went through this in the 1.3 version.

RobertScheitlin__GISP

Lee,

Find these lines in the init function of the SearchWidget.mxml:

if(ViewerContainer.urlConfigParams.search != null){
                    callLater(queryFromURL,[ViewerContainer.urlConfigParams.search,ViewerContainer.urlConfigParams.slayer,ViewerContainer.urlConfigParams.exprnum]);
                }

As far as the not zooming. You got me there as I have not been able to duplicate that issue.

LeeAllen

OK, thanks for that info. I also noticed that I have the datagrid set to fixed and upon passing the parameter when the search is successful, the datagrid is not populated with the information. I haven't made any modifications to the source code except changing a spelling error on lines 2518, 2522 (available) and making the datagrid size 150 instead of 200 (fixedDG). http://gis.snco.us/publicgisApps/PropertySearch/index.html?PRCL_ID=1093104001003000

RobertScheitlin__GISP

Lee,

OK, I see the issue and have it is resolved, you need to get version 2.4.0.5

LeeAllen

Got it! Thanks. I had the zoomscale set to <zoomscale usegeometry="true"/> but changed it to <zoomscale usegeometry="false">5000</zoomscale> and everything behaves as expected.

I am having an issue with the Apply Buffer icon not showing up correctly. I copied the contents of the assets/images eSearch folder to my project�??s assets/images folder. Is there a step I missed? I have attached an image of what the issue looks like.

Thanks,
Sara

RobertScheitlin__GISP

Sara,

The assets/images folder stays in the eSearch folder you should not have to do anything. Flex is case sensitive did you copy the eSearch folder (with the capital S) to your projects widgets folder?

SaraRoth

Thanks for the help! I had changed the file name to "EnhancedSearch". Switching the name to what it was originally fixed the problem.

Hello,

I was wondering if it is possible to perform one search that would query multiple layers/rest services at one time using this widget.

For example, I want to search for an address that would return results from multiple layers/rest services/tables.

Any insight would be greatly appreciated!!

😄

RobertScheitlin__GISP

Emily,

There is currently no support for querying multiple layers using this widget.

RobertScheitlin__GISP

All,

There is a new version out.

Version 2.4.0.7.

http://www.arcgis.com/home/item.html?id=5d4995ccdb99429185dfd8d8fb2a513e

When I changed the default text of the bufferLabel in my Search Widget XML file, there was no change when I opened up my web app. It still said "apply a search distance". However, when I changed the default text for the searchlayerlabel, it worked fine. Any ideas of what is causing this error?

RobertScheitlin__GISP

Sara,

There is an case error in the SearchWidget.xml the bufferLabel in the XML file should be bufferlabel all lower case

So it should look like this:

<bufferlabel>apply a search distance:</bufferlabel>

I will get this corrected in the download.

I am curious if it is possible to have something similar to the following using the linkfield in the esearch widget? This is the syntax I used in the popup code, but would like to achieve the same thing using the esearch widget, where multiple fields are concatenated to pass a parameter to the browser?

<![CDATA[<a href="http://surveyor.slco.org/gis/map/map_search/mrs_test.cfm?mrspoint={POINT_NAME}&lat={LATITUDE_DD}&long={LONGITUDE_DD}">View Mon. Ref Sheet</a>]]>

Thanks!:)

RobertScheitlin__GISP

Emily,

Nope... Not currently but this seems like a good Idea I will add it to the wish list.

AndyWhitley

Robert,
I tried posting this comment on your 2.4 esearch widget page but my messages kept getting cut off. I figured out my issue regarding my post the other day on labels. It was a mistake on my end and the <fields all= needed to be set to true instead of false! Thanks for this widget and the documentation.

EmilyLaMunyon

Thanks for the information Robert!!

I know you are busy, but that would be great to have in the esearch widget because then the link would appear in the table and be easily accessed by the user.

I appreciate all you do:D

EmilyLaMunyon

Hi Robert,

It's Emily again..I know I am full of questions

I have implemented the uncompiled version of your esearch widget in Flash Builder and am looking to make some changes. For instance, if possible, which code/mxml file would I change if I were looking to make the search icons into buttons (similar to the Search and Clear buttons at the bottom)?

Also, how to I remove the search widget icon that appears on the upper left-hand side of the window?

Thanks!
