Editor attribute inspector default values

DavidHollema — Mon, 12 Dec 2011 19:57:23 GMT

I'm curious what some approaches are to providing default values for fields by means of the out-of-the-box attribute inspector. Ideally, I'd like to display the value to the end user in an editable or non-editable text box.

I've tried 3 approaches.

Intercept on layer's BeforeApplyEdits event and provide value based on advice here by Kelly Hutchins -> http://forums.arcgis.com/threads/32271-Default-date-of-1970-for-date-field-at-2.3?highlight=default+values

Use customField based on my own custom dijit for fieldInfo - never successfully completed this. I can see the value in the attribute inspector but it doesn't get transmitted across the wire to ArcGIS Server.

Use customField based on my dijit.form.TextBox - never successfully completed this. I can't see the value in the attribute inspector. I tried setting the 'value' of the textbox in the constructor and later using .set("value").

My own custom dijit attempt is described here

SampleBehavioralDijit

The issue, I suspect, is in how the attribute inspector pulls the values from the form to send off to the post request. Since I'm creating a new dom node, my guess is the attribute inspector doesn't see this value. I prefer this custom dijit approach...can anyone offer assistance?

Setting a value on a custom widget probably won't work because when the attribute editor is displayed it will overwrite your value with the value (perhaps null) for the currently edited feature.

Here's an example that uses the 'onBeforeApplyEdits' approach. Is there a reason you didn't want to use this approach?

Re: Editor attribute inspector default values

DavidHollema — Sun, 12 Dec 2021 05:40:51 GMT

I wanted to ensure that both approaches worked. I tested your code below, paying specific attention to the TextBox you assign to the customField. I ran this against v2.5 CDN and neither the TextBox's placeholder or value was visible in the attribute inspector. I switched to newly released v2.6 CDN and the behavior for the same code is definitely different. I read the bug fixes for 2.6 what's new and see no mention of this.

However, now I'm getting another error upon destroy the editor widget and recreating:

Tried to register widget with id==templateDiv but that id is already registered
http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.6
Line 48

This is a new error with v2.6. I saw it at 2.5 but had it fixed. It's back at 2.6.

Re: Editor attribute inspector default values

DavidHollema — Fri, 16 Dec 2011 16:31:50 GMT

That approach is fine. I was just curious if I can make use of a custom widget or dojo-provided widget to do the same. However, if I were to use a custom dijit to collect special data from the user, it would be nice to set any default value simultaneously in that widget instantiation instead of using the event handling method separately. 1 thing to maintain instead of 2.

Upon creating a new feature with the editor, wouldn't it make sense to omit attempting to read any set field values in the attribute inspector since a feature doesn't yet exist and alternatively read values set in the customField widget? Or, another means altogether to provide a default value, possibly as an addition fieldInfo property?
