Error Evaluating UI Expression Expression evaluation error at function rule!VFM_VehicleReportinterface: Rule 'vfm_vehiclereportinterface' has 1 parameters, but instead passed 0 parameters.

nellorea0001

Hello,

I have created a pie chart and a Grid i two separate interfaces. Now I have taken a new interface and I have designed two sections one for Pie chart and another for Grid. But while creating a report and opening it throws an error - "Error Evaluating UI Expression
Expression evaluation error at function rule!VFM_VehicleReportinterface: Rule 'vfm_vehiclereportinterface' has 1 parameters, but instead passed 0 parameters."

I have also checked in 'vfm_vehiclereportinterface' but couldn't make out the parameters, Thus I request a help.

    Please check the Rule Inputs in VFM_vehicleReportInterface - likely there is one rule input in that rule, and when you call it, you've passed in 0 parameters. If you want the rule input to be null on load, you can define the parameter and just have "rule!VFM_VehicleReportInterface(ruleInput: null)" which should solve your issue.

    Hello Ashvin,

    Yes there is no input rule for this, as the both are graphs how can I use an input rule? The below is the code what i have written for the combination of two interfaces, though I couldn't find the rule input in it. Can you please help where in the code shall I make the change to over come the error.

    =a!formLayout(
    label: "Report",
    instructions: "",

    a!sectionLayout(

    Hi Nellorea,
    I have understood your error, may be you have rule inputs in vfm_vehicleReportinterface() interface but didn't pass parameters when calling the vfm_vehicleReportinterface() interface that's the reason you getting an error on "Error Evaluating UI Expression
    Expression evaluation error at function rule!VFM_VehicleReportinterface: Rule 'vfm_vehiclereportinterface' has 1 parameter, but instead passed 0 parameters.". If you don't want ruleinpts parameter then delete the rule inputs directly.
    if you want to pass the parameters then call the interface as rule!VFM_VehicleReportinterface(ri!ruleinputs). without parameters rule!VFM_VehicleReportinterface().

    Hi,

    I think you have a rule input in your interface vfm_vehiclereportinterface, but you are not passing that to the main rule where you are calling vfm_vehiclereportinterface rule. Pass the rule inputs to main rule which are present in vfm_vehiclereportinterface.

    Hi Devi,
    I have deleted all the rule inputs directly and this worked. Thank You..!!
