What is the maximum value for a drop down list? And after how much data performance will impact ?

I am trying to create a record based dropdown component with a filter (shown below), where the filter value changes based on a different dropdown component. local!msSealType is the variable updated by the other dropdown component (via an a!save in that component) and can be either "S" or "D". The sealType field in the record type I'm using is either "D" or "B". I am trying to filter the options in this dropdown component based on the selection of the other dropdown, but it seems like the filter value is not updating. No matter how local!msSealType changes the dropdown values never change. I have confirmed that both data types are text. Any assistance would be greatly appreciated!

I'm getting this error while updating a form. During creating a form, all goes well but as soon as I try to update the form with existing data (I'm updating a dropdown with a new value and this is where it's erroring out) The dropdown field is being called from another interface, everything in that interface works except for that dropdown. Can anyone please tell me what is going on with the saves? I'm including a screenshot of the dropdown field that's erroring out. Any help is appreciated! Once a new value is selected, the below error occurs Here is the dropdown field for reference. If more screenshots/explanation is needed, please let me know and I'll be happy to provide more!

Hello Appian People, [emoticon:c4563cd7d5574777a71c318021cbbcc8] I have a small doubt. Is it possible to underline and bold any word or sentences at the same time. I tried different approaches but it is failed. The only thing working is: Is it possible that the phrase 'Appian is fun' can be written by both 'Bold' and 'Underline' styles? If yes please try sending the correct codes or explanation. Any suggestions/solutions is greatly appreciated.  Thank you

Hi, I have a dropdown configured in which some of the choice values are high in character value because of which it is getting cut-off. Can anyone suggest any workaround. PS: I am maintaining a look value table from where I am indexing these values.  Sharing the SS below.

Hi, I have several DB tasks shown in a to-do list, where it is possible to reassign these tasks to other users. I need to ensure, just before submitting any task, to check if meanwhile a user has been filling the form, anyone has reassigned that task to another user. In that case, if the user click into the "Complete" button, the task can´t be submitted and a warning must be shown in the form. My approach was create a rule that check the if loggedInUser() match with the user in the column of these record, returning a boolean. When I clicked into the "Complete" button, the rule must be executed and decide if I can submit the task or not.The problem is that that rule is execute just once when the user open the task and I can't find a way to force the execution of therule every time I click into the button. In some tasks there is no option for the user to insert data, only display information and complete the task so refreshing that rule everytime

Hey, I have an interface with multiple interfaces shown up using showwhen conditions.when i click on submit button on the screen then only the process should be started, in the same interface I have file upload component with another submit button , when I click on that submit button the file should be uploaded to the target folder and a process need to be triggered , in the same process i'm using uploaded files ID so i kept submit true. Here I'm facing the issue, when i click on the uploading file submit, the screen is submitting directly and trigerring other process model.Just because submit true is also applied for second submit button. The entire interface is a start form for one process model and there is  another process model triggered using startprocess smart service in uploadfile submit button. Thanks in advance.

Hello, I've been trying to implement this functionality since morning but with no luck. We have a form where the user can input multiple locations if they want to. The functionality is as follows: 1. User fills out the address and additional questions as below The information for these questions is saved in the Input record type which has a one-to-one relationship with Project Location record type.  If the user clicks on add potential location, a new Project Location entry is appended to the existing Project Location array. We need to give the user the option to prepopulate the values of the previous location to the new location if they want.  My approach is as follows: I need to create a local!currentIndex variable that uses wherecontains function to tap into the values and give me the array. I then index into that array and store it to another local variable local!prepopulatedData Problem is, I never used wherecontains before and the logic of this is confusing

I have a file upload component and a form in an interface. In saveinto of file upload component we have a start process and the form is added as a start form in another process model. I have written showwhen conditions for file upload and form that only when the user uploads the file and submits only then the order form should be displayed, but when I upload file and click on submit, the form also gets submitted

Hi! Im having trouble with a Refresh button in an editable grid. The data in the editable grid comes from an expression rule which queries the DB. The thing is, when I have two tabs (lets call them A and B) in the browser with the same interface opened, when I make changes in the Tab A and then refresh the editable grid in Tab B, it works OK and the data is properly refreshed and I see the changes in both tabs. But then, if I make any other change in Tab A, and then I refresh again in Tab B, the data is no more refreshed. To clarify things, if I reload the tab presing F5, the changes made for the 2nd time in Tab A now appears correctly in Tab B, but I want this same behaviour to occur when using the Refresh button in the interface. Thanks! P.D.: If u need some screenshots just let me know and Ill post them ASAP.

We had an interface, while loading the interface in the flow sometimes we are getting Memory Circuit breaker error and we could not able to move forward as we cannot click anything on interface. We already optimized the code to maximum extent. Is there any way that we can show that error in separate section which will not block the interface, so that we can move forward by clicking on submit button

Can we handle the exceptions in Appian interfaces ?
