Hi, I would like to remove an item from a list, depending on a field (here, the condition is : when the "checked" field is false, I need to remove the item) : /* Set to null the unchecked Vehicles items */ a!forEach( items: ri!vehicles, expression: if (rule!SHARED_IsFalse(fv!item.checked), a!save(fv!item, null), a!save(fv!item, fv!item) ) ), /* Remove the null items */ a!save(ri!vehicles, reject(fn!isnull, ri!vehicles)), 1/ How would you code it in a single instruction please ?  (with a foreach and a remove ?)2/ From a SaveInto of an interface the code above works fine, but now I'm trying to execute it from an Expression Rule. So, how would you code this instruction "a!save(fv!item, null)", as a!save cannot be used in ER ? I've tried to use the function updateDictionary(), but I do not see how to set an item to null (I can just set some fields to a null value). I'm sure the answer of the first question can make the

hi,  I have a local variable "array of object" , I need to update value "seenBy" for one field in all array objects, a!flatten(a!forEach( items: local!msg, expression: { a!save(fv!item.id,fv!item.id), a!save(fv!item.isDeleted,fv!item.isDeleted), a!save(fv!item.createdBy,fv!item.createdBy), a!save(fv!item.messageText,fv!item.messageText), a!save(fv!item.convId,fv!item.convId), a!save(fv!item.createdOn,fv!item.createdOn), a!save(fv!item.seenby,concat(fv!item.seenBy, concat(tostring(loggedInUser()) , ",") ), ), } ) ), a!startProcess( processModel: cons!COM_Write_AllMsg_SeenBy, processParameters: { allmsg: ri!allmsg, } ), but the issue is :-  "An error occurred while trying to write to the data store [chatDS].

Hi All , I have a Date and Time field in my CDT (type DATE in the Oracle database). This field has a date and a time. I create a query entity rule with the filter: a!queryFilter(field: "recertificationDate",operator: "=",value: ri!recertificationDate,applyWhen: not(rule!APN_isBlank(ri!recertificationDate))) In the database, I have records with the date and time of 4/15/2019 4:05 PM but when I test my rule with ri!recertificationDate = 4/15/2019 4:05 PM, the rule is returning NO records. Any ideas why this is happening?

Hi All, We have just upgraded to Appian 20.4. I am not sure if the issue due to this but facing very strange scenario when using todate() function in an expression. todate("08/01/2021")<=todate(null)  --> this expression ideally should return false, but instead returning true. It was working as expected earlier. Please advise. Thanks and Regards, Diksha

What is the best way people have found to convert 6 Jan 2021 21:19:42 GMT text into date and time?

We are using out of the box task notification emails and one of the influential users doesn't like the GMT origin time zone on the notification email. I've looked in regional settings per user, looked at the emailheader.html and emailfooter.html system objects, and in admin console, but cannot find a way to localize time per user on these notifications. I'm concerned the only alternative is to eat the system task message and pass along a custom email to the group.  Is this true, or is there something I have overlooked? Thanks for any insight!

Objective: copy data from Process model properties and store the old data copy into same table(Multiple of updates done using interface) before new data update.

Hello,I'm using Export Data Entity to CSV smart service. This gives me CSV output and the CSV has a column named TransId, this column/field is a varchar in Appian.It may contain text and/or sometimes just integer numbers more than 11 digits.The problem here is when the value of this column is more than 11 digits then CSV by default shows value in a scientific format like 1.12233E+13 until the cell of the CSV is formatted to Integer.Is there a way to get the value correctly by default?(This smart service does not have input to take template unlike 'Export CDT to Excel' smart service).

Hi, I have an application developed in angular and java and have around 6 work flows, i want to implement workflows in appian without distrubing angular ui and java,  is this possible in appian , if possible how can u achieve.

I have a customer requirement to allow the users of the application to individually control which columns of information they see on the screen for a given interface. The application will have a default column sequence and that's what every user gets initially. Then each user will have the ability to: Reorder the columns Hide columns from the display Add columns back into the grid that were previously hidden Reset the grid back to the default columns in sequence Anyone have some example code to try and deal with this situation? I'm open to any approaches.

Is it possible to pass the username in a link to site so that the user does not have to key it in, and just provide the password ? 

I have a read-only grid in interface A, and one of the columns populates more than one value. The functionality also includes an expander and each value is linked to its respective record. Below is the code for that particular column. I would like to replicate this functionality in an existing interface B. My concern is that the interface B I am working in has a Paging Grid / Text Column and Interface A has a read-only grid/grid column.  Interface A column code: a!gridColumn( label: "Transit Agency", sortField: "transit_agency_name", value: a!localVariables( local!rowTransitAgencies: index( local!vanpoolTransitAgencies, wherecontains( fv!row.vanpool_id, index( local!vanpoolTransitAgencies, "vanpool_id", {} ) ), {} ), local!rowTrasitAgencyCount: count(local!rowTransitAgencies), local!showPartial: if(local!rowTrasitAgencyCount > 1, true, false), if( local!showPartial, a!richTextDisplayField( value: { a!richTextItem( text: left(fv!row.transit_agency_n

Is there any function to show pop-up in interface ?

Hi all, We want to import an excel/csv file from the file system in the same machine in which Appian runs. Do we need a plugin for that? We can use SFTP services or any other plugin but I wanted to know if Appian offers somethign out of the box. When I look at the excel tools that we have in place they expect that the file is already in the Appian internal DMS. what I have seen so far is that we can use collab filesystem utilities or SFTP utilities. It seems that Appian does not offer something out of the box yet. I am tempted to use the collab filesystem utilities because as far as I know the SFTP utilities require a SFTP client installed in the machine. Any recommendation?
