Attribute window sometimes freezes and doesn't let me enter data

MattMiley — Tue, 12 Apr 2011 22:25:14 GMT

I am using the editor widget and my editor template is pretty big, its got a date picker and 4 drop down choosers and a bunch of empty fields for text only, if I tab through it it works pretty nicely, but if i click each box sometimes it just freezes up and doesn't let me enter any data and it wont let me do anything for like a minute or too, then it lets me click the close only.

Has anyone experienced anything like this?

I think it could be a internet connection problem, cuz when I work on it from my office that is VPNed into the gis server it would happen whenever the vpn looses connection temporarily it freezes like that. But it did the same thing when i was at the server's domian and not using the VPN, so im not sure whats going on.

I have not seen this happen. If it were network-related issue, you can check for NetworkInterface.GetIsNetworkAvailable() http://msdn.microsoft.com/en-us/library/system.net.networkinformation.networkinterface.getisnetworkavailable%28v=vs.95%29.aspx#Y518.

I am getting this same behavior. The Attribute Editor for my EditorWidget is freezing up on me and locking down the application. This tends to happen when I try to edit attributes quickly, but that's not always the case.

My Attribute Window isn't very large, but I do have several fields that are connected to large domains. (i.e. a list of all valid street names in the city) However, it still freezes sometimes when I'm not editing those fields.

Here's my basic setup: I've got a tiled basemap, the Infrastructure Map Service (Dynamic), and a Feature Layer for every feature class in the Infrastructure Map Service (there are 15 total). The Feature Layers default Where Clause is "OBJECTID = 0" to prevent them from all drawing while zoomed out. Instead, the Map Service is used to show the features. After zooming in close enough, (in this case, a resolution of 5.0) the Map Service turns off and the Feature Layers turn on. I also have a ComboBox that contains a list of the Feature Layers. None of the Feature Layers are visible until I select one from the ComboBox, then that FeatureLayer's Where Clause is set to "REMOVED IS NULL" (REMOVED is an attribute that we populate instead of deleting so we can recover accidentally 'deleted' data).

Other than that, it's pretty much exactly the same as the first sample for the EditorWidget. I've checked the log files and added every event handler I could find and none of them can explain what's going on or why the Attribute Editor is freezing up.

Update:

I've been able to narrow down how the FeatureDataForm freezes when trying to edit attributes.

When a user clicks on the FeatureDataForm outside of the textboxes/datepickers/comboboxes (i.e. clicking on the labels or the whitespace) the GotFocus event fires and sets the focus on the first attribute in the form.

Here's the trick. If the first attribute has a domain attached to it (so it's a combobox in the form), the freeze occurs. It doesn't matter how many values are in the domain (i've gotten the freeze to occur with 2 values in a domain).

So, any ideas/suggestions/comments on how to get around this? My current idea is to rearrange the attributes order so that the first attribute is not a domained attribute, but changing the order of attributes is not the easiest thing to do.

Help? Anybody?

@Wkimrey

Is this still the case when working with the EditorWidget and FeatureDataForm or were you able to produce this error with just the FeatureDataForm?

What version of the API are you using?

From what I understand, you are using this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitEditorWidget
with a FeatureLayer which first field is a coded-value domain, such as this service: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/0.

Are you able to reproduce the issue with this service? Can you share with us the steps to reproduce? Did you show the FeatureDataForm as a result of adding a new feature or by clicking on DisplayAttributes button and then selecting a feature? How was your FeatureLayer set up ?(Mode, AutoSave, etc.) If you had only FeatureDataForm, without going through EditorWidget, do you still have this issue (like in this sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataForm)?

I apologize I have more questions.. I could not reproduce it and maybe I am missing steps. I have tried selecting label of the first field but I form does not freeze on me.

The problem is just with the FeatureDataForm.

I've found that this is a known bug with the FeatureDataForm. (NIM063509)

Basically, when the FeatureDataForm tries to edit an attribute that is both a domain value and is the value that the layer uses for rendering different symbologies, the freeze occurs.

I've also learned that this bug has been fixed in the Silverlight API 2.2 Beta, but sadly, that is not an acceptable solution for me since I can't install a Beta product onto our web server. Unless there's something else that comes up, I'll have to wait for the official 2.2 release.

@jenniferdnery

I"m using 2.1 version of the API (build 446)

I've been able to reproduce this error both when I add a new feature and when I select an existing one. I'm not using the "DisplayAttributes" button. Instead, I'm getting the graphic and setting the GraphicSource of the FeatureDataForm in the code-behind.

Here's the setup for my FeatureLayers

DiableClientCaching = true
AutoSave = false
OutFields = "*"
Mode = OnDemand

Is there any indicators from ESRI when this issue (NIM063509) will be fixed? Brad

This bug has been marked fixed prior to v2.2 release.

Hello,
I am not sure if I am having the same problem, but this is the closest string I have seen so far. I am having an issue entering data into the attributes fields. I want to edit attributes, and so I click in the field, begin typing, nothing happens. I feel that it isn't a keyboard or mouse issue, as it never happens when entering data into the find window, only the attribute window. I have fully removed and reinstalled Arc 10, recreated my profile, and even logged in as another user, and it still does it. It is really hindering my job, as I have to try up to three times to enter data before it will take it, for each field. No other users at my office are having this issue. Any suggestions?
Thanks,
Tiffany

Jennifer, according to its status, NIM063509 is still open. I confirmed this with support as i had also read it was fixed prior to 2.2 but this does not appear to be case. This is a bug that really needs fixing (if it does still exist).

I'm running v.2.2.

Something of interest to you is: Home > ArcGIS Viewer for Microsoft Silverlight > User Forums > ArcGIS Viewer for ... > Edit Trouble as it provides some insight into the issue.

Apologies for delay in following this up.

Brad

Hi Brad,

After doing some research, the bug NIM063509 was verified fixed in the Silverlight API v2.2 release. However, in the v2.2 release new functionality was added for types/sub-types which also uses coded value domains and a new �??similar�?� bug got introduced: NIM070962. Both are different issues with almost identical use-cases and this has caused some confusion among the users.

Status: both issues are now fixed at v3.0 beta1 and the forthcoming v2.3 release.

Hope this helps,
