I have a question in regards to the configuration of the Enhanced Time Slider Widget. I am trying to configure the widget to use a time extent and interval that I specify. When I do this I seem to break the widget. MMMM,YYYY false true 1 1000 2000/01/01 05:00:00 UTC 2010/06/01 05:00:00 UTC 1 months If I follow the same methods as the original config file the layers do display properly, but I am more interested in being able to set the time period manually. Any idea what I'm doing wrong above? Using the standard slider that comes with the Flex Viewer everything behaves as I would suspect. Thanks, Adam Z

Config Issues with Enhanced Time Slider Widget version 2.5.1.1 for FlexViewer 2.5

AdamZiegler

I have a question in regards to the configuration of the Enhanced Time Slider Widget. I am trying to configure the widget to use a time extent and interval that I specify. When I do this I seem to break the widget.

<layer label="Surface Water Well Locations" name="Surface Water Well Locations">
<dateformat>MMMM,YYYY</dateformat>
<loop>false</loop>
<singlethumbastimeinstant>true</singlethumbastimeinstant>
<thumbcount>1</thumbcount>
<thumbmovingrate>1000</thumbmovingrate>
<timeextent>
<starttime>2000/01/01 05:00:00 UTC</starttime>
<endtime>2010/06/01 05:00:00 UTC</endtime>
</timeextent>
<timestopsinterval>1</timestopsinterval>
<timestopsunits>months</timestopsunits>
</layer>

If I follow the same methods as the original config file the layers do display properly, but I am more interested in being able to set the time period manually. Any idea what I'm doing wrong above? Using the standard slider that comes with the Flex Viewer everything behaves as I would suspect.

Thanks,

Adam,

Firefox should not be the issue as it is the only browser I normally use. Maybe you didn't clear your cache.

Adam,

Sorry for the delay. I found the error in the code where I was trying to parse the start date and end date twice causing an issue. This is fixed in Version 2.5.2 - April 30, 2012

* The time layer(s) visibility before the widget is opened is remembered and re-applied when
the widget is closed.
* Fixed bug when start date and end date is manually specified for the time extent.

That's great, thank you so much for taking the time to look into this!

I was able to implement the new slider with time extents specified by the config file. Thanks!

Is it possible to have the slider to default to the latest date in the slider versus the first?

Adam Z

RobertScheitlin__GISP

Adam,

Sure that is possible but I don't think that most users would want that to be the default. Are you working with the source code version or the compiled version?

AdamZiegler

Robert,

I'm working with the compiled version....I don't have an IDE set up yet to work with the source code (balking at the price of Flash Builder and can't seem to figure out FlashDevelop). I understand exactly what you're saying about where the slider starts. We are using it to display well samples taken over time but want to the emphasis put on the most recent data and allow the user to go back through time if they so desire. Perhaps I can convince my manager to purchase Flash Builder. What level of the product would you suggest for Flex development?

Adam Z

RobertScheitlin__GISP

Adam,

I can add a configuration opton to this widget in the next release to start the slider at the end. As far as version of Flash Builder, you could easyly get away with just purchasing the standard version.

Very nice work. Do you thinik it would be possible to have the user select a time window instead of specifying a fixed one maybe similar to the animation in Google Earth? thanks. Brian Kaplan, CDC

Brian,

I am not familiar with the annimation in Google Earth that you are speaking of.

BrianKaplan

Hi Robert, I've attached the Google Earth time slider. The half-moon looking item on the bar below the 2 am can be slide left or right and sets the width of the time window. The other item on the bar near the "11" of 11/6/2010 moves the time window. Brian

Hi Robert,

I just downloaded the Enhanced Time Slider for Flex 3.0. I am using the compiled version in the latest Viewer release. I had a question in regards to the auto-toggling. I have the widget open upon load, and it properly has the first layer on and all other's off. As I switch layers it toggles the new ones on but the other layer(s) remain on as well. I checked the live version off the widget download page and this seems to be the case there as well. Is there something in the config that will allow those layers to turn off once they are navigated away from?

Thanks in advance,
Adam Z

RobertScheitlin__GISP

Adam,

This issue has just been fixed and uploaded in version 3.0.1

AdamZiegler

The same behavior still seems to be in place.....

Adam Z

RobertScheitlin__GISP

Adam,

So are you talking about the Old 2.5 version then? I have fixed the 3.0 version.

AdamZiegler

Sorry, I am talking about the 3.0 version. I just downloaded the 3.01 version you just uploaded and the layers are still not toggling off.

Adam Z

RobertScheitlin__GISP

Adam,

Strange I just compiled the change and moved it over to my web server and the toggling on my live preview site is working fine. Do you have the name of the layer in the eTimeWidget.xml the same as the label of the layer in your main config.xml?

AdamZiegler

Okay, it is working properly. I had been viewing everything in Firefox which was causing the problem. When I looked at everything in IE all was good. Not sure if my version of Firefox is bad or if the plug-ins are out of date, but I'll just use IE or the IE tab option in Firefox. Thanks for your help!

Hi Robert,

I wanted to ask if you might still be planning to add this as an option in the config file for this widget? I was also wondering if resetting the time slider to the beginning was a default behavior and if it was possible to maintain the current time when switching between layers.

Thanks,
Adam Z

It must have been a cache problem...all is working properly now. I apologize for raising any alarms. thanks for your help!

I was also wondering if resetting the time slider to the beginning was a default behavior and if it was possible to maintain the current time when switching between layers. It is the default of my design. It would only work to leave the slider in it's current position if the layers all had similar time extents and this will not always be the case.

If you are using uncompiled version, see this post:

Hi Robert,

I finally got FlashBuilder and am looking at your eTime code. I know you said you would add an option to start at the end of the time slider, but any chance you can point me in the direction of adding that functionality myself?

Sorry for pestering, I really appreciate all your help.

Robert, I'm attempting something that maybe isn't right, so that might explain my issues... The only layer I have in my Flexviewer map is a WMS service that has time enabled. I'm assume that this is not supported in this widget?

The link to the time enabled WMS service I'm using is as follows:


            <layer label="Surface Sea Water Velocity" type="wms" visible="true" 
                       visiblelayers="surface_sea_water_velocity"
                       imageFormat="png32"
                       alpha="0.6"
                       skipgetcapabilities="true"
                       usemaptime="true"
                       version="1.1.1"
                       url="http://hfrnet.ucsd.edu:8080/thredds/wms/HFRNet/USWC/6km/hourly/RTV?service=WMS&srs=EPSG:4326"/>

My Widget.xml looks like:

<?xml version="1.0" ?>
<configuration>
 <autotogglelayervisibility>true</autotogglelayervisibility>
 <startatoldesttime>true</startatoldesttime>
        <resetslideronlayerchange>true</resetslideronlayerchange>
 <layers>
  <layer label="Water Velocity" name="Surface Sea Water Velocity">
      <dateformat>MMMM, YYYY</dateformat>
      <loop>false</loop>
      <singlethumbastimeinstant>false</singlethumbastimeinstant>
      <thumbcount>1</thumbcount>
      <thumbmovingrate>1000</thumbmovingrate>
      <timeextent>
          <starttime>2011/10/01 00:00:00 UTC</starttime>
          <endtime>2012/09/05 16:00:00 UTC</endtime>
      </timeextent>
      <timestops>
          <timestopsinterval>1</timestopsinterval>
          <timestopsunits>days</timestopsunits>
      </timestops>
  </layer>
        </layers>
 <labels>
  <timelayerlabel>Select Layer: </timelayerlabel>
 </labels>
</configuration>

Thanks for your assistance,

Frank,

A couple of things.

Using the eTime widget with only one time enabled layer is not the intended use of this widget as the main purpose of this widget is to allow for multiple time enabled layers to be used. This could be the issue, I will need to test. EDIT... Nope this is not the issue, Just tested...
I was not aware that WMS layers were time aware. The Flex API makes no mention of the WMSLayer having any timeinfo or any time properties.

FrankRoberts

Thanks for looking into the WMS topic above. I have since written code to export the data out of NetCDF and then put it into a feature class in the geoDB. My current issues is that my features have a field in them called "bearing". I then rotate the symbol based upon this attribute in the mxd. However, I am noticing a couple things:

1) if I add AGS service as a whole (dynamic), I can get the features to rotate at the different time stamps, however they over post on them selves and look ugly.
2) if I add the AGS service layers as features, they rotation does not occur. They do change colors but the arrows always point north.

Any ideas if this can be overcome? Side note I am using the 3.1 version of the widget currently.

Hope to see you in Palm Springs!
Frank

RobertScheitlin__GISP

Frank,

That all depends on how you have it configured.

<singlethumbastimeinstant>true</singlethumbastimeinstant>
<thumbcount>1</thumbcount>

Should be what the eTimeWidget.xml is configured for. Make sure that your layer in the mxd has time enabled and do not have "display time cumulatively" checked.

2. For the FeatureLayer to use rotation (which would happen client side) you would have to write code to take the value of the rotation field and rotate each makerSymbol from the value of that field.
