Hi all,  i'm encountering trouble with my Admin Profile in a Cloud enviroment. Whenever i try to open properties of a node in Process Modeling or in Modifying a Process, i do not see all the related tabs but only the languages tabs.  Here is a screen:  This problem is present only in production enviroment of a single cloud system. In test, dev and production of other client i dont have this problem.  I've checked my profile in Admin Console and try to find difference with other admin profile that works perfect, but i dont seem to find any.  Tryed even to change browser and cancel cookies and chronology but without any success?  Does anyone encountered and knows something about this problem?  tks for reading 'regards

I have a form where we are showing multiple sections which is collapsable. I made couple of sections as collapsed initially thinking that contents would not load until user expand the section. But its not the case, contents are still evaluating even if section is collapsed by default.  I need certain data to be collapsed to improve the initail loading screen and need to do validation on clicking submit even for collapsed one. Section layout is perfectly doing the validation but its loading the contents in the background. Any suggestions or thoughts?

I am creating this post so that if anyone else runs into the below Error on an Interface, when they try to search for it on Google, they will see this & be able to fix it easily. Interface Definition: Expression evaluation error in rule 'applylocalvartestexpression': local!dollarConversion uses a refresh configuration that is not supported in looping functions other than a!forEach(). All other looping functions do not support variables that use the default behavior or configurations other than "refreshAlways". Change the variables refresh configurations using a!refreshVariable(), pass the necessary variables via rule inputs, or use a!forEach() instead. Root Cause: It is generally recommended to replace load()/with() => a!localVariables(), but when this update is made in an Expression Rule and there is an interface (or interface-dependent Expression Rule) referencing it with an apply(), this will break the interface. This is because "a!localVariables does n

Hi together,I have a "map" value in a process. I realized that an IsNull/emptycheck rule I used in a gateway down the line, was failing of evaluating that there was (in my understanding) an empty valuecast( 'type!{http://www.appian.com/ae/types/2009}Boolean', length(a!flatten(ri!value)) = 0 )Even the new rules a!isNullOrEmpty ..... are not recognizing this properly. Does anybody experienced this as well? (not difficult to solve, but it was pretty unexpected) Kind regards, Richard

There are multiple objects in Appian that help us developers to design and build dynamic, fresh, and good-looking interfaces. Sometimes, however, we find the existing components restrictive, preventing us from fully customizing them and building around a specific interface look. This thread, in particular, is about the component BoxLayout, which, after some discussion with our team, has shown a lot of potential to upgrade both functionally and aesthetically. As shown in the screenshot, we have come up with the idea of adding new parameters to the existing component that we think will allow more detail-focused developers to have full access to the colors and style of the component. Also, we think it would be interesting to have full control over the margins that affect the component, in order to build around it more easily. Thanks in advance. Fran.

Hi,  I want to remove the null value keys from the list of the map below.

I’m building an interface where the user is asked: "Do you want to use your previous data?" If the user selects Yes and clicks the Continue button, I want the following flow: Show a loading GIF screen immediately). In the background, fetch the user's previous data using a rule and save it to a local variable. Once the data is available, automatically transition to a new screen that displays this data. Problem:If I try to show the GIF and fetch the data in the same saveInto (e.g. within the button click), the interface waits for the data fetch to complete before updating the UI. As a result, the loading GIF doesn't appear immediately — it only flashes briefly or doesn't show at all. I am sure we can easily manage it at process model end. but trying to see if anyone has done it at interface level which i can reuse.

Hello, is there any way of associating a heading tag <H1>  to the site display name? Many thanks SimonJ

We did cleaning up of process model version for around 800+ process models in our environment. But we didnt see any reduction in memory utlization % or disk used %. Can anyone tell where versions are stored and how they affect memory utilization??

Hi All, hope you all are doing great, I'm getting the following error:Error Evaluating UI Expression Expression evaluation error [evaluation ID = PNO05] in rule 'abs_clientsearchresponse2' (called by rule 'abs_clientsearchrequest2') : A null parameter has been passed. When trying to invoke a process model inside a!gridColumn as follows: a!gridColumn( label: "BUC", value: a!richTextDisplayField( label: fv!row.IDE_CLIENTE, value: a!richTextItem( text: fv!row.IDE_CLIENTE, link: a!startProcessLink( processModel: cons!ABS_CLIENT_REQUEST2_PM, processParameters: { buc: fv!row.IDE_CLIENTE } ), linkStyle: "STANDALONE", color: "NEGATIVE", size: "STANDARD", style: "STRONG" ) ), align: "CENTER" ) The rule: 'abs_clientsearchresponse2' is displaying the row without any error: But when I click over the BUC link, the above error is displayed, the pv is declared as Parameter with the same name in the PM,

Has anyone figured out a way to export a DMN file from the Decision Table in Appian? We want Appian to be the source of the rules, but we need the DMN model so we can execute the logic on another offline system which must get the same results as if it were run on Appian. Appian claims it uses DMN, but doesn't actually supply the DMN model...which seems odd. Thanks.

I am planning to take Certification ACD200. Is there any prerequisite before taking ACD200?  Can I take the exam directly or should I need to pass ACD100 before ACD200? 

Is it possible in Appian to have sound on click? like on cards, charts, gauge etc.

Hi EveryoneI’m using a custom picker as a user picker to select users based on custom properties. However, I’ve run into an issue:       •     If I type something in the picker but then erase it without selecting a suggestion, the field ends up holding a garbage or null value.       •     This behavior causes unexpected results in my form/data submission. Has anyone faced a similar issue? If so, what’s the best way to handle it — for example, ensuring the field resets properly or validating before submission?

Hi team We've just set up an application that uses the Send E-Mail Smart Service. Our Health Check Report has this to say: "SAL Approve Installation (0002edb5-ade8-8000-43ed-7f0000014e7a) Node: ""Send To user"" references a smart service that is no longer recommended for use (Send E-Mail). Please remap this node in the process model to use the latest version." I can find nothing in Appian documentation saying Send E-Mail is no longer recommended for use I can find no details in Appian documentation of any Smart Service that might replace this I can't seem to find a thread in this Community that addresses this issue Can anyone assist me to resolve this?Thanks and blessings Stephen

Trying to move the logic from query entity connecting to VW to Proc with input parameter and was able to create a Procedure on Maria DB . Challenge is trying to recreate includes operator logic for an column on proc using LIKE operator but not able to achieve it 100% currently got to an extend as below , there are multiple input paramter on WHERE clause and one below AND ( input_parameter IS NULL OR input_parameter = '' OR REPLACE (LOWER(COLUMN_NAME),' ' , '')  LIKE REPLACE (LOWER(input_parameter),' ' , '') ) additional checks made From Appian while passing the input parameter have also converted the input parameter to lower case and have appended %% before and after the string Input parameter definition have set charset as per the column definition. Still issue is value with alphanumeric value ending with number fails Ex: %abc1234_def4%. No result (actual record exists), but %abc1234_def% gives results 

Hi Community, I was exploring a scenario, where when user loads records summary page, I want write some data into Records /enitty. I tried to create a web API which writes records, an integration to connect the web API, call that integration from local variable inside the interface. But this doesn't seem to be working. When I tested web api from integration object , I am getting below details as response but its not writing the data    Any work around or other approach to achieve this? Thanks in advance

The basic user who has viewer permission can't initiate the send email node? Will it get errored at send email node?

I am running some processing in parallel that includes api calls.The result with then populate an interface attended by a user. I have tried both a!forEach and MNI but for both the performance is not as expected. By looking at the performance tab in the expression rule, it is clear that the items in the array are running sequentially and not in parallel, as the total time for the expression rule is the sum of every iteration. As a test I tried to put only a GET api call in the foreach loop and the result is the same. This is not what I was expecting, is there anything that can be done to enforce the threads to run in parallel to optimize the performance?
