My use case is as follows: I have a CDT of dates and number of days.  I have the first date, but the others are not populated yet.  My goal is to populate each subsequent date with the previous indexes date + the number of days of the current iteration. For example I start with the following: {9/27/2021, 0}, {null,3}, {null,5} I want the output to be as follows: {9/27/2021, 0}, {9/30/2021,3}, {10/5/2021,5} Each iteration will reference the previous iteration's date to generate its own date. I appreciate your time and help!

Hello community, I wonder if this a bug or I am doing something wrong.we use Appian 20.4. If I try to get the data of a map using index or property it always returns default value when present.This behavior only occurs in the process model and not in a expression object.e.g.pv!testMap: a!map(errormessage: "something went wrong"), then this code property(pv!testMap, "errormessage",  "default") or the same using Index function.Will return "default". dot notation works: pv!testMap.errormessage wil return: "something went wrong".property or index without a default works: property(pv!testMap, "errormessage") wil return: something went wrong". Maybe I overlook something, got it working by the way by casting the map to a map but that makes no sense off course. Kind Regards, Erik

Hello, I am trying to create a connected system in Appian to connect a BluePrism, I am getting error trying to test the connection. Here are some additional details: i have created a bot in blueprism in my pc for demo, I have exposed a BluePrism process that I can access locally  by going to localhost:8181/.../. In Appian I have tried entering the Host URL in the following format: DESKTOP-NQK6NPJ:8181/.../ DESKTOP-NQK6NPJ:8181/.../ But I am not having any luck testing the connection. Any help would be much appreciated.

Good morning, We have the need to set up an integration to call us and return a response from a file. We are creating a WebApi that receives an XML and raises a processModel, does the validations and returns the response. The problem is when we have to make that it does not exceed 20 seconds. We are putting a control timer, but this timer makes that when calling the WebApi it finishes without waiting the 20 seconds. Thank you Alex

Hi All, What is the best way to point out missing features of Appian? I am just wondering if there is any feedback mechanism aside to the community and support cases specifically for this purpose. I do already experience good support from Appian in general, but I am wondering if there is any place where I can view (and vote) new requested features / Appian roadmap? For example I am missing: Adding a dynamic link in an empty grid message Disable future dates in the date input field, https://community.appian.com/discussions/f/rules/18008/calendar-blockout-disable-hide-of-future-dates/70841#70841 I understand there are other priorities, but it would be nice to have an official avenue for submitting ideas. See also this related thread https://community.appian.com/discussions/f/user-interface/12151/product-improvement-idea Thanks in advance, Jesper

Good afternoon We have a problem with the delay of a start timer, the timer has to run every X minutes (set to a constant).We have created a rule to delay us so that the process runs at the exact minute.For example, if it's 6:26 p.m. and we run every 15 minutes and publish right now, what we want is to set a 4-minute delay so that the process doesn't start until 6:30 p.m. The problem is that the process is not starting and we do not know what we are doing wrong. The code: load( local!intervalos: ( 60 / ri!duracion ) + 1, local!enumeration: enumerate( local!intervalos ), local!intervalosFinal: a!forEach( local!enumeration, fv!item * ri!duracion ), local!retardo: reject( fn!isnull, a!forEach( local!intervalosFinal, if( and( minute( local( now() ) ) > fv!item, minute( local( now() ) ) < local!intervalosFinal[fv!index + 1] ), local!intervalosFinal[fv!index + 1] - minute( local( now() ) ), null ) ) ), if( or( isnull( local!retardo ), local!retardo = "", length( lo

Hi, Is there any way to display textField/radioButtonField 's in gridRowLayout based on satisfying given condition ? I have a column, it can be of either dropdown or text field or radiobutton.

Hi I've started getting this error the last week or so - http error 503 when I click on Process activity, or indeed any of the other tabs in the image. Happens the first time I click, but not the second. What could be going on here? Browser issue? Network latency? It also happens in on of our applications in a record type sort - again the first time the user clicks on the column heading. Using chrome, 93.0.4577.63. Can make the error go away by cleaning out the cache, but this could be just coincidental? Seeing this in the tomcat log at around the same time, this is the first few lines.

Hello All, I was exploring if we have any option to use Windows Command in Interface. The requirement is to have print functionality through Appian. In the current solution a print icon is provide which opens up an interface through a process. The interface is added as start form to the process. Once the interface is launched users have to key-in "Control + P" to print. So my question - is it possible that if the clicks the print icon it runs the print command and the document is sent for printing. Thanks & Regards Girish Katti

Hi everyone. We are building a grid with data records in it. What we want to do is add a button above the grid, that when clicked, will unlock all the rows for editing and when clicked again will lock the rows. In other words, if a user clicks the button, all the fields will turn into text fields and if clicked again the fields would go back to read-only.   Any suggestions for how to go about this?
