Hello everybody we have got this message in tomcat logs: "A high-memory expression evaluation was logged, but the evaluation was not identified. The expressions aborted log will not contain all evaluation info" and this message is repeated several times and between every occurrence there are the lines that I have put in the log in attachment. I would ask if someone has ever met this error, or in alternative if you can give to me some hints,  after the reading of the log, that in my opinion in quite hard to understand. Thank you in advance for any help or suggestion, best regards Paolo [View:/cfs-file/__key/communityserver-discussions-components-files/11/log.txt:87:58]

Hi, There is a CDT which is calling a Sequence in Oracle as a primary key. Below is the extract from CDT. <xsd:element name="recordId" nillable="true" type="xsd:int"> <xsd:annotation> <xsd:appinfo source="appian.jpa">@Column(name="RECORD_ID") @Id @GeneratedValue @SequenceGenerator(name="sequence", sequenceName="A_RECORD_ID", allocationSize=1)</xsd:appinfo> </xsd:annotation> </xsd:element> For some reason, when we are trying to insert data in the table some other sequence is being called and we are getting "Unique key Violation". We are able to identify that sequence but not able to figure how this is happening. We could not find any trigger in the table. Any pointers would be highly appreciated.

 hi all, We have a view for bar cart field which recently bracked in prod due heavy volume of data approx (1,048,576) records in my sql db .  so we plan to query data going with sp with (executestoredprocedure) function. my question is can we query data in a barcart field with SP ? while executing SP  with mandatory  parameters getting error as "Use the Execute Stored Procedure Smart Service to modify data. This function must only be used to query data, not modify." if i pass optional parameters also getting error as "The conversion from UNKNOWN to UNKNOWN is unsupported". Below is the code for SP,  a!localVariables( local!sp: fn!executestoredprocedure( cons!DATA_SCOURCE_NAME, cons!TASK_GRAPHIC_SUMMARY, { { name:"assignedTo", value:ri!currentUserEmail }, { name:"categoryName", value:ri!categoryName }, { name:"lob", value:ri!lob }, { name:"assignedcategory", value:ri!assignedcategory },

My Appian Timezone is set to Pacific time Below functions are returning correct time now()  -   2/20/2023 5:40 AM PST datetime(year(now()),month(now()),day(now()),hour(now()),minute(now()))   -  2/20/2023 5:40 AM PST However, when I try to create datetime where I want to change the date and time acc to my preference, the timezone offset gets added.  datetime(year(now()),month(now()),day(now()),0,0) – 2/19/2023 4:00 PM PST   I want the output as - 2/20/2023 12:00 AM PST       Requirement for which I want to create datetime in specific timezone. Now I want to create a datetime so that I can use it to filter the datetime column stored in DB I need to fetch all rows from DB where the createdDate is say 2/20/2023 so for that I thought of creating a query filter as Date between (2/20/2023 12:0AM PST and 2/20/2023 11:59 PM PST). However I am unable to create datetime in particular time zone  

Hi all. I'd like to know if Appian can be integrated with a versioning software like CVS. The goal is to store each Appian component version with the ability of identify who modified a component, what changes are made and recover old version. Thanks in advance.

Dear community, within our project we have the requirement of full traceability from a work-item in azure devops to the actual code changes. Are there best practices to do that within the Appian environment or possibilies which would allow us for example to force the user to enter a description before he can save an object, automatically export the objects from Appian via a Rest-Api and then commit them in git ?  Thanks, Patrick

Hey Guys, I am using the a!recordactionfield in a separate interface to add the data. It contains card layout for each of the data we added. Is there anyway to refresh the page while submitting the data using dialog box option. All process model nodes are chained and when I used the "open in same tab" option it refreshes the data but from the dialog box it does not refresh. I also used the a!refreshvariable in the local variable in interface but it doesnot work.
