User Experience Design

Hi, I am getting an error when I click on any dynamic link or button in my task (with no submit). I only have this error when I access the task from the mobile application, from the browser everything works correctly. The error is "An error was encountered while processing your request", and I don't know how to get more information about it, maybe in the STDOUT log? I have deleted any operation in saveInto for testing, and I still have the problem, It seems that it is simply by clicking Could someone explain to me what could be happening? Thanks and regards

Hi All, We have build an application wherein we have some DB calls happening on the main page and then there is a a!startProcessLink() action configured to modify any data. Everything is working correctly but as soon as a!startProcessLink() is completed, the main interface reloads causing every DB calls to re-execute. We know this can be handled properly via recordType but as per our requirement that is not the suitable option. Can anyone suggest how we can stop making these extra calls if possible? Thanks in advance

When a user adds a text value to a floating point field, Appian displays a validation message by default. However, when the user clicks the refresh button in the same UI, all validations should be cleared and the fields should be reset. Unfortunately, Appian's default validations are not refreshing properly in this scenario. Is there a solution to refresh the validations after clicking the button in the same UI, without using record actions?

Hi Champs, I have a portal having milestone section. I have a landing page and once user click the "Start Application button" in landing page, the milestone starts. In each of the page, I have a option to proceed next, back and cancel button. There are some mandatory fields in each of the pages without which the page won't proceed ahead and gives the validation message. It's working fine; but there is one issue. When I am cancelling the form, it's coming back to landing page and then when I am clicking next, automatically it's showing the mandatory field validation without even user clicking the next button. How can I reset it, so that it will only show the message when user click the next button only. Regards, Ghanashyam

Hi all, I have encountered an issue in an interface while switching from expression mode to design mode in Appian. The issue is mainly cause of nested indexing (An alternate approach that I have used in UI). Below are 2 code snippets, while switching to design mode, the second snippet causes the error to appear. I am trying to use a single index() instead of nested index(), is there any sort of performance difference between these two approaches, or any benefit of one over the other? a!localVariables( local!list: { a!map(key: "test1"), a!map(key: "test2"), a!map(key: "test3") }, a!textField( value: index(index(local!list, 1, {}), "key", {}) ) ) /* Works well */ a!localVariables( local!list: { a!map(key: "test1"), a!map(key: "test2"), a!map(key: "test3") }, a!textField(value: index(local!list, 1, "key", {})) ) /* Gives error in switching to design mode */ Error: Cannot switch to Design Mode The function 'index' [line 7] has 3 p

Hi all,  I have this issue: i want to select somehow a specified row in a!griedfield component, like ID 24 in the picture below, then start a process with some value taken from that row, with a submit buttom or something similar that can appear when the specified row is selected. Is it possible to achieve this goal? This is a screenshot of my site in which the element of the only read grid are taken from a recordtype, so this is why the ID is coloured in blue.  Thank you in advance for the responces. 

I need to allow the user to enter a comment in an interface.  This comment might be 200-500 characters long and might contain line breaks (CR or CRLF). The a!textField allows for the character limitation, but not for multi-line display, wrapping long lines, including line breaks.   Is there a control that provides multi-line text input?  (Like this 'description' field I'm using to enter this community post.) Thank you.

Hi,  I have a read only grid, which has various filters. For one of my filter, I have the different stages (New, In progress, Done). When the grid is viewed from the front end, I want to initially filter out the stage ( Done) and show the remaining stages. In that case, when a user want to see the "Done" records, they can cancel out the filter. Can someone help here.

I tried adding a YouTube video to an interface but it ends up blank. a!videoField( videos: { a!webVideo( source: document(21953,"url") ) } ) I tried using this code and for source I tried replacing it with the YouTube video url which didn't work also. Do I need the mp4 of the video in documents or are YouTube videos not compatible?
