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.

Hi Robert,
I wondered if there is a way to append to selection set using the enhanced search widget? If I select a subdivision boundary using the point select tool in the graphical search tools and then use the spatial search tools and select the parcels that are entirely contained within the subdivision boundary, I get all but three parcels. Obviously, our subdivision boundary needs to be corrected, but in the meantime, I would like to be able to add those three parcels to the selection set so I can export all of them to a csv from your datagrid table.
Thanks,
Caitlin

RobertScheitlin__GISP

Caitlin,

Currently No and it is not going to make it into the 2.5 version of the widget either.

Ken,

If you bring up your REST Service directory for this layer does the ACREAGEDOM field show the coded values like this:

Surf_Type (Type: esriFieldTypeSmallInteger, Alias: Surface Type, Domain: Coded Values: [1: Tar and Gravel], [2: Asphalt], [3: Chert], ...2 more... )

KenCarrier

One thing I failed to mention, the domains exist on subtypes not on the default field, could that be causing the issue? I reviewed the SearchWidget.mxml code, I am not a Flex developer but I did not see any error trapping for subtypes within the code, although I might have missed it.

RobertScheitlin__GISP

Ken,

Ken it could be subtypes as I don't use those and probably have not accounted for them in the code. Is your data with subtypes public?

KenCarrier

Robert,

I am not sure what you mean by public, it is a public facing website.

I tried setting up the domain on the default field as well as the subtype but still no luck.

I basically have 3 subtypes pertaining to the type of land i.e.(RESIDENTIAL,COMMERICIAL,AGRICULTURAL). Within each subtype I use a domain, it is the same domain. I tried setting the domain on the field instead of just the subtype but still get the same error. I am currently developing on a local machine. So the functionality I mentioned is not public facing yet.

I know you are busy and this might only pertain to me currently, but do you think adding this functionality might help others within the community?

RobertScheitlin__GISP

Ken,

I am sure it would be benificial to others and I am working on the version 2.5 release so this is good timing. Is the REST service available for me to test against (the way you originally had it with the domain on the subtype)?

KenCarrier

Robert,

I have reverted the rest endpoint back to how it was originally with the domains on the subtypes.

Here is the rest url

http://gis.monroeohio.org/MONGIS/rest/services/AvailableLand/MapServer/1

Thank you taking the time to look at this!

Robert,

I found your previous post regarding an edit to the MXML very helpful and easy to execute as far as implementing the code.

When I went forward and attempted to compile the code I ran into some issues.

I found this video helpful (https://www.youtube.com/watch?v=25uC2e3LsLk&feature=player_embedded) in laying out the basic steps for compilation, but after adding the edited MXML as a module I ran into multiple errors that appeared in two major groups;

1) 1120: Access of undefined property SearchWidget. SearchWidgetFloatDG.mxml /Modified/src/widgets/eSearch line 752 Flex Problem (~4 errors)

2) 1046: Type was not found or was not a compile-time constant: SearchWidget. SearchWidgetFloatDG.mxml /Modified/src/widgets/eSearch line 752 Flex Problem (~5 errors)

Any suggestions you have as to tackling this issue would be greatly appreciated.

- Rick

Rick,

There is no configuration option for disabling certain graphical search button as you have figured out but you can simply locate the MXML Group with the id of graphicalInput and add:
visible="false"
                          includeInLayout="false"
to the particular mx images (graphical Search Buttons) that you do not want shown. Make sure you don not try this for the eDrawBtn or the pBufferBtn to disable those just set them to false in the SearchWidget.xml
<enabledrawgraphicbutton>false</enabledrawgraphicbutton>
    <enablebuffergraphicbutton>false</enablebuffergraphicbutton>

RobertScheitlin__GISP

Kenneth,

Your issue is that the source path is hard coded many time in the code so the fact that you have the widgets path as /Modified/src/widgets/eSearch instead of src/widgets/eSearch is a big issue. Try making the suggested code changes to the code in the original location instead.

RobertScheitlin__GISP

Ken,

Domains that are attached to sub types will be fixed in the eSearch version 2.5 due to release in conjunction with the Flex Viewer 2.5 (coming very soon).

KenCarrier

Robert,

Thank you very much, I will be anxiously awaiting the release of the Flex 2.5 API. Do you think this will happen before the end of the year?

Ken,

RobertScheitlin__GISP

Ken,

Yes 2.5 is on schedule for before the end of year so far.

KenCarrier

Great thank you very much. Once it gets released and I have had time to upgrade my app and widgets I will get back with you on the results. Thank you again for your contributions to the community we greatly appreciate all the help!

Robert,

Thank you for your quick response yet again.

When I am importing the source code for Flex 2.4 as a project into Flash Builder it automatically prompts me import a new copy of the project / extract project to folder x.

This was "Modified" as seen above or "FlexViewer" as I have tried in subsequent attempts, and it appears that this file path is the source of the problem with the hardcoding that you previously mentioned.

How do I avoid this issue and implement the code changes in the original location as you had previously suggested?

Thanks again for your assistance,

Kenneth

RobertScheitlin__GISP

Kenneth,

Here are some steps you can follow:

1) Copy the contents of the flexviewer-2.4-src folder (i.e .settings, html-template, libs, locale, src, etc)
2) Create a "Flash Builder 4.5" folder in the root of your C:\ drive (This is a preference as I don't like my projects buried in my user folder).
3) In Flash Builder File menu choose Switch Workspace > Other and browse to the "Flash Builder 4.5" folder you created in step 2.
4) Back in windows explorer (or my computer) create a folder in the "Flash Builder 4.5" folder and call it "FlexViewer2.4"
5) Paste the contents from step 1 in this folder.
6) In Flash Builder from the File menu choose Import Flash Builder Project... > choose Project folder > Browse and choose the "FlexViewer2.4" folder from step 4 and click finish.
7) When it Asks about what Adobe SDK to use (hopefully you have already downloaded the Adobe 4.1 SDK) choose 4.1. If not then click the "Configure Flex SDK" > "Find and download other versions of Flex SDK" > Download Flex 4 SDKs > Flex 4.1 Update Adobe Flex SDK (169 mb) > once it is downloaded then extract it to C:\Program Files\Adobe\Adobe Flash Builder 4.5\sdks\4.1.0 > back in the prefferences dialog choose Add... > Browse and C:\Program Files\Adobe\Adobe Flash Builder 4.5\sdks\4.1.0 > ok
😎 Copy the eSearch source folder (from the download you did of it) and paste it into the widgets folder.
9) Right click on the FlexViewer2.4 project in the package explorer and choose properties > Flex Modules > Add > Source > Browse > src\widgets\eSearch\SearchWidget.mxml > ok.
10) Repeat the add button and Source > Browse > src\widgets\eSearch\SearchWidgetFixedDG.mxml > ok.

and finally your done.

Robert,
I split the Enhanced Search Widget into two different widgets. One has the text search, the other has the graphical search. Everything is working great, except when I try to export the results as a CSV file. For one of the widgets, the fields are now separated by quotation marks instead of being in different columns. The other widget still works great. I believe that this is because its folder name is still "eSearch" and the other widget's folder is now called "eSearch_Text". What changes in the code would I need to make, so that the export function will work correctly for both widgets?

ExcelScreenCapture.jpg

RobertScheitlin__GISP

Sara,

Well that is kind of a loaded question as there could be a vast number of things that have gone wrong... Are you saying that you just copied the widget and set the disablebuttons element in the copies SearchWidget.xml? So much more information is needed for me even have an idea of were to being. Are you using the latest version?

RobertScheitlin__GISP

All,

Version 2.5 now available for Flex Viewer 2.5

Version 2.5 - 12/2/2011
* Added Related table display capabilities for searched features
* Added support for domains that come from subtypes.

KenCarrier

Robert,

I am still getting an error when trying to use these two tags "usedomains" and "fromsubtype". Any help would be greatly appreciated. I using the same rest endpoint specified in previous post. I am using the latest 2.5 eSearch widget and have updated my compiler with the latest version of the Flex API.

Robert,

Thank you I have gotten past that error and understand it better now. The query is still not working as expected. Here is the new config. I wanted to implement a multi field search but I think in previous posts you have mentioned this is not possible. So for example select PROPTYPE then based on the PROPTYPE select AGREAGE from the subtype. To get around this I thought I would just use a definitionexpression. Here is the code I have so far. I apologize for my ignorance hopefully this will help someone else in the future.

Robert,

I figured it out, because I am using a coded value domain of type Short Integer, the single quotes around [value] were what was causing the problem with the search. If it were text then it would work. Thank you again for all your help it is greatly appreciated.

Does not work with Coded Value Domain on Short Integer field:
<expression alias="Available Land Agriculture" textsearchlabel="Search Available Land Agriculture by Acreage..." field="ACREAGEDOM" usedomain="true" fromsubtype="true">ACREAGEDOM = '[value]'</expression>

Works with Coded Value Domain on Short Integer field:
<expression alias="Available Land Agriculture" textsearchlabel="Search Available Land Agriculture by Acreage..." field="ACREAGEDOM" usedomain="true" fromsubtype="true">ACREAGEDOM = [value]</expression>

KenCarrier

Robert,

Is it possible to have more than one linkfield or specify multiple linkfields?

<linkfield linkaliastext="Brochure Link: Get More Info">HYPERLINK</linkfield>
<linkfield linkaliastext="Auditor Link: Get More Info">AUDHYPLNK</linkfield>

RobertScheitlin__GISP

Ken,

No there is no support for multiple link fields. Some people have extended the code themselves to add this ability, so it is possible.

KenCarrier

Robert,

I think I might have found a possible bug. In the attached screen shot you will notice that the datagrid is showing the subtype number instead of the description. In the other windows the subtype description is used instead of the number. Hope this helps.

RobertScheitlin__GISP

Ken,

That is fixed in Version 2.5.0.1 (now Available).

KenCarrier

Thanks Robert!

Hi Robert,

What is the best way to make the check box for "add search tolerance to point selection" to be "checked" by default.

The reason I ask is that i cannot get the point selection tool to actually select a point feature unless I check the box first. It seems kind of redudant, unless I am missing something. I have set the toleranceforpointgraphicalselection value to 100. If you set this value, would you not want the user to use this as the default.

Thanks for any assistance or direction that you can provide.

Mark
