It strips accented letters (à, é, ó) along with the invalid characters. The document only fails to save because of invalid XML control characters in the source text, so remove just those with regexreplaceall("[\x00-\x08\x0B\x0C\x0E-\x1F]", yourText, "") and keep the template UTF-8 encoded.

I am using clean fucntion before passing the sentences to do document template. If I don't use clean the generated document dont even getting saved in the process output even for english templates. Below is smart services I use to get the pdf generated. This is how it appear in the grid This is how it looks when printed, Is there any way to fix this.documentcleanPDF Doc from Templatesmart servicepluginshttps://community.appian.com/discussions/f/plug-ins/40361/issues-with-adt-files/154981Tue, 23 Jun 2026 09:25:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:e530b403-5963-4926-9a6e-ce2852013623forsake202145Thank for your support. https://community.appian. retro bowl .com/discussions/f/plug-ins/40438/advanced-document-templatinghttps://community.appian.com/discussions/f/plug-ins/40491/html-to-pdf-conversion-2-1-6/154980Tue, 23 Jun 2026 08:13:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ce7c292b-d18a-4675-86a2-6ebdce43d427forsake202145I ran into something similar a while back.

Is custom SFDC development truly unavoidable for these crucial credentials? I recall a similar predicament integrating an inventory system with a new e-commerce platform; the API documentation was sparse, and crucial security keys were seemingly behind an unopenable door. It felt like trying to beat a level of geometry dash blindfolded.https://community.appian.com/discussions/f/new-to-appian/40518/missing-tutorial-application-acme-sport-equipment-rental/154978Tue, 23 Jun 2026 05:47:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7001de85-25d9-4d2e-940a-f24e055e5f3bStefan HelzleI suggest to write to academy@appian.com.https://community.appian.com/discussions/f/new-to-appian/40518/missing-tutorial-application-acme-sport-equipment-rentalTue, 23 Jun 2026 03:39:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5e3f4bf4-2609-49b5-8ed2-91a8d5d0e281TimBurns203785Good evening, I have been going through the developer learning path. On the course to start developing an application as a step by step, I appear to be missing the main tutorial application that is referenced in the guide (acme-sport-equipment-rental). I see the solution, but not the practice app. Any thoughts or guidance would be great. Thanks.https://community.appian.com/discussions/f/rules/40517/ai-user-chatbot/154977Mon, 22 Jun 2026 19:18:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:63afa376-e668-4b3b-9c72-90e9fa3d4025Stefan HelzleOK. I did not expect you are running a process. In my use cases I use separate LLM providers and simple integrations to make calls.https://community.appian.com/discussions/f/rules/40517/ai-user-chatbot/154976Mon, 22 Jun 2026 18:24:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ad36432c-ed46-447b-b78f-3c687b6e3d73rohity0003Here is the best solution I've come up with so far: In User Input text box's saveInto Block: 1. update isProcessing 2. call processModel to call AI Skill (isSynchronous=false) 2a. In 'onSuccess' block, read processId into a local variable. A separate sub-interface loads ( when isProcessing = true ). This has a local variable processingDone that checks every 30 seconds (refreshVariable) to see if the process is done ( using a process report). When processingDone = true, a link appears to 'Show Results'. - When clicked, this reads in the data that was calculated by the (AI Skill) process.https://community.appian.com/discussions/f/rules/40517/ai-user-chatbot/154975Mon, 22 Jun 2026 17:16:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7412de6a-0a05-458d-add7-eba0478a0653rohity0003Hello Shubham, If I put isProcessing=true and startProcess(calling AI Skill) in same saveInto block: isProcessing will not show up as True until the startProcess is finished processing ( by the that time the processing is done). I've found that saveInto executes as a single block. It does not update interface until the entire block is finished. Thanks for your time.https://community.appian.com/discussions/f/rules/40517/ai-user-chatbot/154974Mon, 22 Jun 2026 17:12:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7a525235-cfa9-436b-a44f-f979d0ff2141rohity0003Hi Stefan, thanks for the idea. Here is what I ran into: I need two events to happen in following sequence: step 1: isProcessing is marked as true (allowing user to see a processing indicator on screen). step 2: AI skill is called (via processModel), which generates process variables that I am reading back into interface. aSyncVariable solution: I can get aSyncvariable to run, when isProcessing is updated, but for the value of the variable, it does not like me to run a process. Is there another way to run a process using aSyncVariable as trigger?
