Hi, I am using Community Edition and  following the Appian Developer path. In for Step-By-Step # 10 I am getting expression error while adding the reusable component on a interface/form.  I followed all the steps till this section and all works good. As per Step by Step #10, Guide I am trying to complete the following steps. as soon as I click ok, above expression error message displayed.  Any suggestions to fix this ? 

i am getting the above error when i am trying to edit "display value" in "addedBy". below expression i have used- rule!W0866aa_FormatDisplayName(user:fv!row[recordType!W0866aaVehicle.fields.addedBy]) given in guide -

Hello,  I have a text field who's value is linked to a dropdown field. If the dropdown value changes, the text field automatically changes as well. The text field is disabled as the user should not be able to change the value. The problem I have is that the value of this text field should be saved into a rule input but since I do not interact with the text field, the save into parameter does not trigger. I have no buttons on the interface so I could not add an a!save there. The user does not have to interact with any other field if they don't want so I couldn't put the a!save in another field as well.  Is there a way for the text field to refresh without interacting with it to trigger the save into?

If a user has indirect access to a record type as viewer. Will he able to export and download the record report? Thank you!

In my application, there are three columns for each user in the default Group; Name, Details, and Member Type. I would like to add additional fields for users so that we can separate them based on their roles and grant them different access.  Is there a way to add additional fields to the user groups? I tried to do some research into this and it seems like Group Types are the way to go but I am unable to figure out how to set it up. Specifically, I want to add something like these fields to the user table.  <Name>   <Region>  <Country>  <Department>  Do I create a Group Type for each new column? How do I add the values for each field so it can be a drop down list? Thanks.

I am new to Appian and I'm creating a form interface to save data to the database. I've gone through several of the tutorials and I created an Interface and a Process Model that will save data to the database. However, it only works when I launch it from the Process Model. How do I launch it from the Interface by clicking on the Submit button?  I want to click Submit after filling out the Interface and have it fire up the process model to save to the database.

Hello, I’m currently using the free Appian Community Edition. After being inactive for ~1 month, I logged back in and my environment has been stuck on “Workspace Pending” for the past 24 hours. Is this normal, and how much longer should I expect before I can access my workspace again? Any guidance would be appreciated.
