Hi All,  I am new to Appian, I would like to know what are support provided for backward compatibility.  If we have created an app using Appian latest version, later if we have a new release, then does it affects the working app or there will no impact.  Additionally, how can we check the frequency of new releases, Where can we get information regarding version backward compatible. How may version are backward compatible with new release. ? Do appian charges for every release?

For example I made a process where I send an email that already has an html template and replace the input with a dictionary with data to be sent. But when it is sent my table that is in the template gets ";" over the table as I'm going to show you here. Someone knows why he put the ";"

Greetings All, I manually created three tables using the Cloud Database tool.  I specified the primary key, foreign keys and populated the tables with data. I then created an application.  I created Data Types, Data Stores and Records.  I then created an grid interfaces and I was able to see my data. After some thoughts about how I named the application and if I should have select 'From Scratch', I DELETED the application. I then created a new application and started to create a Data Type (or is it Custom Data Type) to connect to the existing physical tables I previously used. I then discovered that my tables (along with the data) are now gone. I am guessing I did something wrong.  If I had five applications using the same tables, it would seem counterproductive to have all of the physical tables being deleted because I deleted one application that refers to them. Thanks for any help and advice!! Best, Paul

Greetings All, Now that I am able to create a CDT, I immediately see that I have some decisions to make with respect to what the UI looks like.  In my world, we have reservations with various pickup and dropoff types.  Previously, I have just thrown them all into one reservation table/record and used pickup_type = A, F, T, P and dropoff_type = A, F, T, P to show or hide different datawindows to display the data as necessary. For one reservation that I display the pickup or dropoff type could be: 'A' = Address 'F' = Flight 'T' = Train 'P' = Private Jetport Here is an example of Pickup Type = A / Dropoff Type = F (DROP AT AIRPORT): And here is an example of Pickup Type = A and Dropoff Type = A (DROP AT ADDRESS): I would like to create interfaces that show the screens mocked up as above.  Obviously, the dropoff layout for an address is laid out very different from dropoff layout for an airport.  And of course they use differe

Greetings All, I am not seeing this error when I search the community so I am asking for help here. I created a CDT from a table called Trip.  Now I am trying to create a User Interface as a Read-Only Grid.  I am prompted to select the data source and I select Record Type.  I type in the name of the CDT and I see it as an option.  When I select it, I get the error as shown in the subject line.  Below is a screenshot of the error.  Any help will be appreciated.  Best, Paul

Greetings All, I am new to Appian.  First I would like to thank Appian for creating the Community Edition.  Fabulous!! I have been through various courses relating to records and database concepts. I have experience with database design and I used the database tools to create three tables in the Appian schema with the necessary columns, primary keys and foreign key relationships.  I also manually populated some rows of data into these tables. I created a new application.  I think I now have to create Records that refer or point to these physical tables?  Or do I need to create Datastores and then Records that refer to the Datastores? I am happy to take a course that discusses these concepts, but I am having trouble finding information that ties the physical tables to objects that I would use in process models or with interfaces. Thanks very much for any pointers!! Paul

Hi, I have a editable grid where in one field has single select dropdown (i.e Status), a!localVariables( local!data: rule!Data_Rule( serialNumber: null, pageBatchSize: -1 ), local!statusToUpdate, { a!gridLayout( label: "Editable Grid", labelPosition: "COLLAPSED", headerCells: { a!gridLayoutHeaderCell(label: "Serial Number"), a!gridLayoutHeaderCell(label: "Status") }, columnConfigs: {}, rows: { a!forEach( items: local!data, expression: { a!gridRowLayout( contents: { a!textField( label: "Serial Number", value: fv!item.serialNumber ), a!dropdownField( label: "Status", labelPosition: "ABOVE", choiceLabels: rule!RWM_Status_Matrix_Rule(currentStatus:fv!item.currentStatus), choiceValues: rule!RWM_Status_Matri

Questions related to deployment? 1. When deploying, is it right to deliver all source (interface, rule) files publicly?    If all source files are publicly delivered, won't the operation side also be able to access and make development changes? 2. In the case of JAVA, the source is converted to a JAR file through the compilation process and the inside cannot be seen.     What should I do if I want this result? 3. If all sources are opened after deployment, how do I set up security for it?     

Is it possible to fold options in checkboxField inside Hamburger like button (to have the behavior of dropdown) in Appian?

Hi Folks, I am building the below logic i.e comparing the two local variables values if that is true then it has to perform the logic (i.e) 1*50 or else should return the null values. And it has to save the value when I click the button continue. As we cannot save multiple values as a same target in a!save(), Now I am facing issue in saving the values. If I define any one logic in a!save()  that is working, whereas for multiple logic it is not working. Below I have attached my code, you can refer from line 101 to 147. Please suggest If there is any alternative approach for the below logic. a!localVariables( local!type, local!quanity, local!button, { a!cardLayout( style:"SUCCESS", contents:{ a!columnsLayout( columns:{ a!columnLayout( width:"MEDIUM", contents: { a!textField( label:"MENU", readOnly:true(), ), /*a!textField(readOnly:true() ),*/ a!dr
