I have a Sharepoint list customized PowerApp, where if I am opening any item in view/edit mode - it will show me the data of the previously opened item. But when I refresh the browser, the data is correct.
I tried adding :- Refresh (DataSource) in the onsuccess property of the form,
[ turn "Off" the experimental data cache under Settings ] - this is not available now.

I have created a manual spinner in PowerApps in a SharePoint Integration App, with three different screens & respective forms.
Purpose: Loader should be visible when the PowerApps is loading data.
Steps I followed:
Add rectangle and Spinner Image as a group
Visibility of group = LoaderVisibility (variable declared below)
set(LoaderVisible,true) - onview property of SharePoint Integration
Add timer control, duration- 2000,Autostart- true, onTimerEnd- Set(LoaderVisible,false)
Issue: It is working fine when you are opening any of the item at first. But the spinner will go into infinite loop if you open another item in Edit/View mode without refreshing the browser. It seems like variable cache issue, because the spinner of View screen is impacting Edit screen as well though it has different spinner.
I tried clearing cache from browser and setting (LoaderVisble,Blank()) - to clear the variable at first before using it again but no luck.
I am preparing a Power Apps web portal. But when I am adding a Form on my page and testing on browser, subgrid is not showing.
Preview on Web browser image which does not show Subgrid:
This is my developing screen where I'm adding a Web Form:
Because the form in Insert mode, try changing it to Edit mode to see the subgrid. You cannot add child records in subgrid unless parent entity record is saved/created/inserted, that is the reason.
When creating a new entity form, the first step is to decide the Entity and Form Name that you will be rendering, in addition to the mode: Insert, Edit, or Read Only. The mode selected will determine if you are creating a new record from the portal, editing an existing record, or just displaying information about a record on the portal.

In my implementation (configuring from scratch), when I click on a button from Contact, on click of a button, I am calling an action which will open a new case with Customer Data prepopulated on New case form.
Below are events that triggered after clicking the button.
But in USD, Case Hosted Control s opening with empty page.
I have did the same implementation in another environment, where Sample Configuration data was installed and it worked fine. See the below events that triggered after clicking the button.
So many events triggered in my environment, where I have sample data configuration. What have I missed?
The session data disappears when a page is duplicated a few times in Chrome/Firefox.
Below is an example:
Load http://www.example.com/parent/test.
This page has a search feature which on click invokes a Python script that sets a session variable and redirects to a page template http://www.example.com/parent/redirected which accesses the session variable.
On http://www.example.com, from a dropdown menu "Test" is selected which leads the user to "http://www.example.com/parent/test" page. On this page, once you hit search and immediately try to open another page on the website by "Opening in New tab", the original page does not load the results because the session is somehow empty now (session.get('variable') is empty) and hence "http://www.example.com/parent/redirected" does not load anything.
This seems to happen with Zope's built-in session manager and the effect is more pronounced when Beaker is used.
I've been trying to find a cause for this error for some time to no avail...
We have a SharePoint 2007 site heavily customized in terms of look and feel.
In the master page a user control has been inserted that uses an update panel to partially render updates in the control.
The User control seems to work fine on all pages unless a search web part is inserted into the page.
The control has a DropDownList that according to user choice hides or shows different panels.
There are also buttons that cause async postbacks within each of the panels.
When a "Search Core Results" webpart is inserted into a page, all async requests cause a javascript error and no updates occur in the update panel.
The javascipt error is:
Sys.WebForms.PageRequestManagerServerErrorException:
Object reference not set to an
instance of an object.
The problem is I can't even figure out what this object is. It seems to be the ScriptManager (although its there in the master page).
Is there a way to get a detailed description of this error?
Also, are there are any known conflicts or issues with update panels and SharePoint search web parts?
I'm relatively new to SharePoint development and am still trying to find my way around customizing and debugging.
Update:
I used fiddler to examine the requests and responses.
In the request, the only difference I see is that without the search webpart it contains an NTLM authorization header, while the request on the page with the webpart has no authorization header.
In the response, the page that works has a private cache-control with some cookies set (i guess for authentication), while the other no-cache nor cookies set. Also, the response text contains the updated control when it works, while the other page returns this:
53|error|500|Object reference not set to an instance of an object.|
Could authorization be the issue here?
you are used visible property for hide DropDownList control or not
If not then please used visible property for
