Advanced Training(Academy 2) Practice 1 (UiDemo) InitAllApplications xaml help



I’m in need of help as I’m stuck in the middle of assignment 1 in Academy 2 (UiDemo Walkthrough)

When I run the InitAllApplications xaml I am getting this error:

The file path in the open application activity is set to:


and I have an Orchestrator text asset set to the same name: “UiDemoPath” with the value set to the file path on my local computer stored and set to the same name in config file.

What am I doing wrong? How is the InitAllApplications workflow supposed to work?

Attached is my workflow.

InitAllApplications.xaml (7.3 KB)

UiDemo Walkthrough Assign Problem

Hi @DGold195,

There nothing wrong in the workflow as such. Were did you add the UiDemoPath ? Note that it has to be added in the Assets Sheet in Config.xlsx file.

Do let me know if this helps. :slight_smile:

I’m having the same issue here. Should I put the actual file path on the description field or do I have to place it somewhere else? Also, should we import the variable from Login.xaml to the invoke activity of InitAllApp?

thank you.


I want use UiDemo (advanced outline1). I execute InitAllSettings.xaml it is unable to read inside config.xlsx with write line fuctions I see that all row().tostring are null. I extract data from this file with VBA and Java J2EE without problem.

  • I check with writing sheet names only null returns
  • I check with value name only null returns
    I don’t know how to fix it.


I just solve this problem, now InitAllSetting (I’m not sure) and InitAllApplication are working…


UiDemo don’t work, it is too long make workable. I begin the next exercise…
For html screen scraping I have many messages ‘Attribut not supported by UiCurrent node’. When it works I’can’t filter data. Can I take this data without scraping?


you directly use data scraping screen scraping is not at all required and from the datatable generated from data scraping we can filter the data


Thanks, so first I scrape all data from the page inside a table and after I filter it.
I see a method to filter rows.



Tanks for your help.
I extract data from html page to a input table. Afer I select some data inside a System.Data.DataRow[] and cast it by C# to a output table.
all tables are put on Excel files so see data.


Hi, so I’m having the same problem. I have in_Config(“UiDemoPath”).ToString in File Name of Open application. In the Config file (Assets sheet) I have Name: UiDemoPath Asset: UiDemoPath. In connected Orchestrator, in the Assets I have an Asset named UiDemoPath (Text) Value: my path (which is correct). So where is the problem? Thanks.


Hello guys.

In Orchestrator the UiDemoPath was in quotes and that was the problem.
I removed quotes and after that the UiDemo runs correctly.

Best regards,


Check also your Arguments and Variables related to UiDemo Path and config file :wink:
