Is it possible to configure an input field so that when a user enters a url it w

Not directly, but you could put a text under it that would display the entered link.

Hi Michael, one way you might be able to do this is by using the a!linkField() function.
Ex. a!linkField(
links:a!safeLink(
label:"User's entered url",
uri:ri!uri
)
)
Where ri!uri is the entered url.

Note that the user will have to enter the url in a text input field first and then you can dynamically show the link to the url using the expression above.

Hi Ruth! that would do it - thanks!!!

Sure, no problem! Also, keep in mind that the uri must be 'valid' for this to work. See this link as a guide; forum.appian.com/.../Data_Types.html

Worked like a charm - thanks Ruth!

Hi Ruth, ok I spoke to soon - it worked fine in the SAIL Interface, but not in Tempo. I get an error that there is an expression evaluation error in my rule, that it is not a permitted URI under the configured security rules and cannot be cast to safeUri. My code is as follows:

a!textField(
label: "Sample Report URL",
instructions: "Enter the URL for the sample report here, in http://url.com format.",
labelPosition: "ADJACENT",
saveInto: ri!dqrr_dataQualityReportRequestCDT.dqaFulfillmentURL
),
a!linkField(
links:a!safeLink(
label:"Click here to access the URL",
uri:ri!dqrr_dataQualityReportRequestCDT.dqaFulfillmentURL)
),

Hey Michael, it doesn't seem like you are validating against a null value for your rule input. If you have the Appian Common Objects in your environment, and assuming the CDT itself is not null, try this:
a!textField(
label: "Sample Report URL",
instructions: "Enter the URL for the sample report here, in http://url.com format.",
labelPosition: "ADJACENT",
saveInto: ri!dqrr_dataQualityReportRequestCDT.dqaFulfillmentURL
),
if(rule!APN_isEmpty(ri!dqrr_dataQualityReportRequestCDT.dqaFulfillmentURL),{},
a!linkField(
links:a!safeLink(
label:"Click here to access the URL",
uri:ri!dqrr_dataQualityReportRequestCDT.dqaFulfillmentURL)
)
).
Also note you might need to validate the URL entered.

yep that did it Ruth, thanks again!
