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.

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.

RobertScheitlin__GISP

Lee,

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

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

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

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.

GladwinHenry

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

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

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.

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

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, 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,

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,
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,

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

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] = "";
       }

IrfanClemsonUser

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);
}

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!

RobertScheitlin__GISP

All,

   Version 2.4 for FlexViewer 2.4 is now released.

* Both the compiled and uncompiled version can use the URL Search capability.
No code changes needed!
    See the Enhanced Search Widget URL Search Configuration.pdf
* Links in the results, popUp and Data grid now do not display a link if the link field contains
    a Null or empty string.
* Fixed error when clearing the graphics results and using the fixed data grid.
* Fixed issue with buffer point widget button displaying as enabled after you hover over it, even
    though it is not enabled.

RobertScheitlin__GISP

Frank,

Sure that will be done in Version 2.4 of this widget.

FrankRoberts

Robert, I had a user ask about the text on the transparency slider for the buffer. They didn't know what "Adjust buff alpha" meant... I know you and I know what this means, but I was wondering if you could add this label to the other labels in the config file for a future revision?

Just a thought, thanks again for the wonderful widget!
Frank

EmilyLaMunyon

Thanks for the reply Robert. I was talking about the new fixed grid, I appreciate the information:)

RobertScheitlin__GISP

Emily,

If you are speaking of the floating datagrid then there is close button in the upper right corner like most widgets. If you are talking about the new Fixed grid than NO it is developed to always be visible.

EmilyLaMunyon

Sorry, I have another question.

I have the data grid working great using the compiled version. Is there any plans in the future to have something like a show/hide option for the grid?

Thanks!

EmilyLaMunyon

Never mind. It worked using this:

<field name="page_id" gridfield="true" hyperlinkgridfield="true" hyperlinkaliastext="Corner Reports" linkprefix="http://surveyor.slco.org/gis/map/Corner_Reports/getImage.cfm?page_id=" linksuffix=".pdf"/>

Thanks!

EmilyLaMunyon

Hi Robert,

Thanks for this great widget!! I have a question regarding the hyperlink field in the grid table. In the pop-ups I am able to enter a link like this:
<a href="http://surveyor.slco.org/gis/map/Corner_Reports/getImage.cfm?page_id={page_id}.pdf">View Corner Reports</a>.

Is this functionality possible here, and if not, is it something that could be in future releases. It has allowed me to solve a huge issue I had of accessing images from a SQL database.

Thanks!
Emily

RobertScheitlin__GISP

Geoff,

This will be fixed in version 2.4

HalilSiddique

Thanks Robert, Hyperlinks now working.

RobertScheitlin__GISP

Caitlin,

Sounds like you do not have the fields configured correctly the widget. Depending on how old a version of the eSearch widget you were using there has been alot to change in the SearchWidget.xml file. Look at the Enhanced Search Widget XML Configuration.pdf

CaitlinBernier

Hi Robert,

I have been away from my Flex Viewer development for a while but have now returned. I am setting up a new eSearch for addresses. When you run the search, you get results but there is no text in the results window, nor is there text in the grid or in the popup. The locations are showing up but I cannot see the attributes at all. It is very odd. Do you have any idea what might be causing this? The other site I have set up with the same version of the eSearch widget works fine. Hmmm.

Thanks in advance for your help.

Caitlin Bernier

I have run into a bug with the results showing in the grid function. It seems that even if there is a <null> location in the database the location still has a link appear.

here is an example of the code i am working with

<field name="SURVEYS" alias="Surveys" hyperlinkgridfield="true" hyperlinkaliastext="View Surveys" linkprefix="http://maps.clemson.edu/culandmanagementv2/" linksuffix="" gridfieldonly="false"/>

The table fields in the database complete the url and if there is a table field titled <null> a link still shows up with the linkprefix: ex: http://maps.clemson.edu/culandmanagementv2/<null>
