Hi, I am developing a function plugin for appian. I am following the steps in this page https://docs.appian.com/suite/help/20.2/Custom_Function_Plug-ins.html am confused about one thing. Where do I actually include the java files for my plugin? I am inclined to put them under the functionPlugin package, but the documentation is confusing.  This is my current path. I have appian SDK and google 3rd party library under referenced libraries. Is it fine to include 3rd party libraries, and did I locate them in the right folder? The reason I am confused if I included the dependencies in the right folder is that in the url above. it is mentioned in step 14 to "Add any JAR files required by your custom function to the src/META-INF/lib/ folder." Technically my function depends on the ORTools library, but can't i just use it as a referenced library?  this is what they recommend on the website.  do the dots in  "com.example.plugins.<YOUR_

Hi, My use case is the following. I need to automatically assign new daily batch of tasks to workers. Each task, worker has a set of skills. The task's skills must match the worker's.  Additionally, the algorithm must assign/distribute tasks as equally as possible.  I have come up with a way to do this by reducing this to a graph/flow problem. Problem is, it is super hard/impossible to implement this in an expression rule. As such, I want to develop a custom function in appian in Java.  Which way is better to this, via Servlet or custom plugin?  Thank you,

Hello everybody,in one cloud of ours (running Appian 21.2) we are facing this issue.We have uploaded the plugin: "Text File Utilities 2.0.0" in order to use the readtextfromfile() function.When we type the name of the function readtextfromfile in a rule, the name of functionis suggested by Appian, but when we execute the function, the following message appears:"Expression evaluation error at function 'readtextfromfile': The function 'readtextfromfile' is unavailable."I also looked at in the tomcat-Stdout.log of today but I did not find nothing related to this plugin nor to the function. Last, this problem does not arise in my personal Community Edition.Could you please give me some advice or suggestion? Any help is greatly appreciated, thank you in advance.Best regards,Paolo

Hello. We are having a very unusual problem with the Reconcile Doc Extraction Smart Service node in our process models. Everyone in our team can run the process model, start the document extraction and run the reconcile node without issues, except for a specific user. The error is the following: An unexpected error occurred while displaying the PDF for the run. We tried the following methods/verifications in order to debug the problem: The user is a System Administrator; The user belongs to the same groups that the other users belong to; The user has Admin privileges to the document used; We tried multiple process models in order to try to isolate the problem, but the issue persist even if we use a "sandbox" process model. For the users who run without issues, the process is the following: For this particular user, the process fails on the reconciliation node: Whenever the user tries to "View Form" on the reconciliation node, the user gets immediately the error

We are facing issues with PDF from Single DOCX plugin when generating a PDF doc form DOCX. This plugin is working whit out any issues until 21.2 Version. We recently upgraded one environment to Appian latest version 21.3. After this upgrade the PDF from Single DOCX (with Fonts) smart service is breaking when generating  document. The same DOCX document we will be able to convert in other environments(21.2). We are not sure what is the root cause. Could any one know the root cause for this issue.

We are exploring calling Appian as a Client API from a custom component (docs.appian.com/.../reference-js-api.html, and I'm looking into ways to get a user's service context in order to exectue some backend services (i.e. ContentService). I could probably make some calls via Integrations/Web APIs instead, but I'm trying to work with document manipulation, so everything needs to happen server-side and it seems clunky to have my ClientAPI call an Appian WebAPI vs use public API calls. I see few other components out there are executing ServiceContextFactory.getServiceContext(username)**; but when I've tried to replicate that, but my component is returning a 500 error and this exception: --- "com.appiancorp.connectedsystems.templateframework.functions.pipeline.proxyDecoratorPipeline.TemplateInvocationException: Contact the developer of this template to resolve the following issue. java.lang.VerifyError: Bad return type Exception Details: Location: com/appiancorp/s

Hello. In my particular use case. I need to integrate Appian to Azure. Mainly because I want Azure to conduct a query for me. The reason for this is that I am dealing with a database type that is not supported by Appian so I need to find a workaround. The workaround is to pass the query from appian to azure, make Azure execute the query and retrieve the required data from the database, and pass the results back to Appian.  I am fairly new to both Appian and Azure.  Can anyone here give me a rough guideline as to where to start?
