I wish to dispatch an customized event in my widget. what i have done in my widget is this:
step 1: i created an event type:
<fx:Metadata>
[Event(name="mywidgetevent", type="flash.events.Event")]
</fx:Metadata>

then in step 2: i have invoked this event using

var eventObject:Event=new Event("mywidgetevent");
dispatchEvent(eventObject);

Now I wish to use this event handler. can i use this widget in my application using <components tag> becaz than i can catch the event and write eventhandler for this. If not what is other way of doing this.

eSearch problem (older version)

Hi guys,

I'm using an older version of eSearch (2.x) in an important custom mapping app and I'm working with Flash Builder/Flex 4.6 to get ready for the move to 3.0 Viewer (after the Holidays). However, it'd be nice to resolve this problem (in the interim for the client): After obtaining search results into a datagrid (fixed), the datagrid appears too large for its window (for lack of a better term) and overlaps the boundaries of the window when many columns are returned. How can I set the datagrid's width to not exceed its window?

I am wondering if the solution lies in using a Spark datagrid? It's probably a quick fix but I'm not good with Spark yet... Any help would be appreciated.

Here are the uncompiled files in my eSearch widget, and I can post the code if needed:

assets.images
alphaSliderSkin.mxml
ArrayCollectionExtended.as
CollapsiblePanel.as
ExportButtonSkin.mxml
HyperlinkColumn.mxml
joinDataGridColumn.as
ResizeTitleWindow.as

Configuring pop-ups in ArcGIS Viewer for Flex 3.0

Re: configuring pop-ups in 3.0:

I'm under the impression that it's best to choose to configure the pop-up using either:
1) the Application Builder via the <description> tag -- I like this option because I can format my text using the HTML tags, OR
2) the XML <configuration> -- I like this option because I can use numeric and date formatting tags on FIELD values.

I cannot see examples of how to either:
1) format date or number FIELDS within the <description> tag, OR
2) format non-field text without the <description> tag

Following an example here, I can create the pop-up via the XML file, using <description> and <field> tags, like this:
Code:
<configuration>   
        <title>Prioritized Tracts</title>   
        <description><![CDATA[
                <br><i><b>Name:</b></i>  {TRACTNAME}       
                <br><i><b>GIS Acres:</b></i>  {GIS_ACRES}       
                <br><i><b>Salesforce:</b></i>  <a href="{SALESFORCE_URL}"> (Link) </a><br>]]></description>               
                <fields>
                        <field name = "GIS_ACRES">                               
                                <format usethousandsseparator="true"/>                               
                                <format precision="0"/>                       
                        </field>       
                </fields>
</configuration>
BUT, if I then view the code inside the Application Builder, all my field formatting gets deleted from the XML (everything below </description>)... this seems risky since I move between App Builder and configuration files.

It seems safer to choose either <description> or <configuration>, rather than mixing the two, but I don't know how to do all the formatting I need using either option.

Any advice is welcome.

Oh, and my pop-up doesn't seem complicated, I need to be able to do these things:

Name: Green Acres (bold/italics formatting on the left-hand column names)
Acres: 2,550 (bold/italics formatting, and the FIELD needs precision and thousandsseparator formatting on its value)
Date Protected: 2/3/2010 (bold/italics formatting, and the FIELD needs date formatting on its value)

Adding new features with EDIT WIDGET

I am trying to configure a feature service to be an editable layer in my FLEX application. I have added a new feature class to my database and published the MXD as a feature service. I can configure the edit widget in the FLEX viewer and everything seems fine.

When I go the the URL of my application and try to add points using the EDIT WIDGET, it allows me to place a point and enter values for all of the attributes. The problem occurs when I click "OK" to save the point(s). As soon as I click "OK", the point disappears.

I go back to the MXD to see if they are actually saving in the feature class, but I'm not having any luck. What could be the problem?

REST service Has No Arrow In Legend Widget

November 29, 2012, 9:31 am

Hello,

In the flex viewer, I have added dynamic layer urls to connect to an arcserver rest service. This rest service is published via the internet (someone else's server). The flex viewer app opens fine with no errors. However, In the legend widget, the layers do not have the arrow next to them, and do not draw (appear to be connected). I can see the rest endpoint and the layers underneath it just fine (from the same server where the viewer app is published).

Anybody know how I can determine problem? Is it network related? How to isolate the performance through the viewer application, when the rest service url works fine?

Thanks,
Jodi

perhaps someone can point me in the right direction, or provide more info.

I'm making a flex application with an editable feature service . . . which is why I'm in this forum, though I'm not sure if this is entirely a flex 'thing'

I'd like for this application to be publicly available to browse, but also within the application I'd like to have my feature service only editable by select users in my arcgis online organizational account.

How can this be achieved?

Thanks.

                                                                for (i = 0; i < vizLayers.length; i++)
                                                                {
                                                                        vizLayers[i] = Number(vizLayers[i]); // convert to Numbers
                                                                }

                                                        break;
                                                }
This allows me to pick from a list, and load the service into the current map.
Was wondering if there is a way to set the popupconfig file to use for each sublayer (similar to the config.xml file) so that when i load the service with the widget (something like in red above), it will recongnize the appropriate popupconfig.xml file?

Thanks for any suggestions,

Need help on customizing edit widget/attribute inspector

November 30, 2012, 7:32 am
$

I want to add a button to a customized version of EditWidgetAttributeInspectorSkin.mxml to be used with the edit widget when a specific config.xml is being used to allow the update of a specific attribute on a road feature layer. I have the standard edit widget working and the only editable attribute appears and can be updated. The problem is if you select multiple roads and want to change the attribute on all of them to the same value, you have to do it one at a time. I want to have a button on the skin that you can click to set the attribute to the selected value on all of the selected features.

I've looked at the mxml source to the editwidget and the editwidgetattributeinspectorskin and I don't know how to proceed. I can add a button to the skin, but not sure what to do to enable it and make use of it. When it's clicked, I want it to loop through all selected features and change the attribute from its present value to the one selected in the EditWidgetAttributeInspectorSkin by the user. Sounds simple :^)

I'm hoping one of you with more programming experience can help increase my knowledge through this.

Thanks

Displaying multiple features in popup windows

November 30, 2012, 9:42 am

Hi,
does anyone know how to hook into the popup window functionality that's built into the Flex 3.0 API?

The online documentation on popup configuration files (http://resources.arcgis.com/en/help/...000002q000000/) states, "This pop-up functionality is built in to the API and is not a separate widget."

Additionally, the "What's New" (http://resources.arcgis.com/en/help/...0000011000000/) section states as one of the enhancements for the 3.0 pre-release, "Pop-up windows contain multiple features".

Given that a lot of effort has gone into providing this functionality and a lot of effort can also be expended on setup of the popup config XML files, it would be great to be able to make use of this throughout the Flex Viewer application.

I understand that setting the value of map.infoWindowRenderersEnabled true/false effectively turns on/off this functionality for when a user clicks on the map.

Is there any way to programatically access this functionality???

For example, I would like to be able to show a popup for all features found at the location of a graphic centerpoint when the user hovers the mouse over that graphic. I know I could configure my own infoWindowRenderers but this seems highly redundant if I've already defined the popup config for every layer in my map in the main configuration file and I would also have to find a way to implement the "multiple features in a popup" functionality myself.

thanks,
Nic

hash table does not return data in sharedDataupdate2

I have successfully achieved the widget communication following widget communication.pdf Prepared By: Robert J. Scheitlin. I have noticed one thing and it is that when sharedDataUpdated2 is fired the hash table does not contain any data, why it is so?. however when the sharedDataUpdated is fired than array collection data array contains the data. i have applied this lines of code in init function of basewidget:
AppEvent.addListener(AppEvent.DATA_PUBLISH, sharedDataUpdated);
AppEvent.addListener(AppEvent.DATA_SENT, sharedDataUpdated2);
fetchSharedData();

and in the sharedDataupdated2 i have following code:
var dataTable:Hashtable = event.data as Hashtable
however event.data does not contain any data and all of its key are empty as i checked in the debugger. therfore when i checked dataTable.find("KernelDensityData") IT RETURNS FALSE. there only sharedDataupDated returns the data but sharedDataupdated2 does not.
Any thought please.
