Update property not working well with changed name columns from MS List

[xing_fu_ul]

Hi there,

I suppose it is a bug as I have two field in one app.

I fixed one by removed the column from List, removed the datacard from PowerApps Canvas, and add it again in both List and Canvas, it works.

Another one have same issue and not working.

Simplified issue:

I had related two columns in MS List, created name A (choices) and B (person). Then I add them in powerapp canvas, with update property: {value; a_string_variable} for A, a_person_variable for B.  it works.

Then I rename A and B to a and b from MS list. Though I revised accordingly in canvas, still the update property did not work, without any error.

a screenshot of the datacard not sure if it helps but just to provide some extra information:

DataField is the origin column name when created, DisplayName is the new name. Even if I changed the DataField, after few hours reopening the powerapp, it changes back.

Not sure if MS people could see it, but just a reminder to all developers.

Hi @xing_fu_ul ,

Thanks for your sharing.

Could you please tell me where and how you set the update properties?

This is an article about column names in SharePoint

https://plumsail.com/docs/help-desk-o365/v1.x/How%20To/Find%20the%20internal%20name%20of%20SharePoin...

The display name is a name that was given to a column when it was created, and it is the name that is shown to end user. The internal name is obtained from display name. And after the column is created, the internal name will not be change.

The DataField of Datacard is mapped to the card form the datasource, It does not seem to be used to modify column names in sharepoint.

If you have any thoughts, please share with us.

Best Regards,

Zhi Chen

你好，具体是这样配置的。我有另一个字段和这个完全一样，但是那个字段对应list的column是没有改过名字的，就一切正常。

status_str 由一个button onselect属性触发UpdateContext。 具体如下（这个status_str有设置一个单独的label检测，其赋值都是正常的。）：

我重新在list添加了一个column，在powerapp也重新添加了datacard后就没再有问题了。

我猜测应该是powerapp和list之间的某个只和update相关的映射有问题
