Stucking on redirecting to next question

Hi balamanchari murugadas ,

could you elaborate more to better understand.

As per my understanding when you click on next button the process is ending instead of next question on the screen, i suspect you have used 'submit:true()' parameter in the next button. so the process is ending. Make sure 'submit:false' if you are using userinput task in the process.

a!localVariables(

a!save(

I have to store score and name for this I need to use process model in process model 1 st question only coming next the node is ending I can't  able to create a processmodel. 

That is because you saved it first on line 84 and then you updated it on line 97.

     want to store in database it's not getting store it is giving error like this     

An error occurred while trying to write to the entity "reportData_entity" [id=9f6550f9-4c37-4bd3-8ab3-92b6cf0c0e7c@3448, type=OQA_Report_Data (id=3982)] (data store: OQA_N_excelData). Details: javax.persistence.PersistenceException: org.hibernate.TypeMismatchException: Provided id of the wrong type for class OQAReportDataDT3422. Expected: class java.lang.Integer, got class java.util.ArrayList: org.hibernate.TypeMismatchException: Provided id of the wrong type for class OQAReportDataDT3422. Expected: class java.lang.Integer, got class java.util.ArrayList Data: TypedValue[it=3982,v={<null>,BalaManchari,2}]

There is a type mismatch. A column seems to have received an array in place of an integer value. Verify your mapping again in the Datastore and look for a type mismatch in the value. 

i mapped correctly i believe but its giving error in variable the data is getting store but its getting error

I guess you need to set your process variable to Multiple and also in the Data tab as well check the multiple option. Is it defined as an array in your rule input on interface? (Hope I am not reading the error incorrectly)

Thank you for your guidenceHarshit Bumb (Appyzie). I completed.

Superb! Now when you have done it, please take a moment to verify the answers that worked for you to close the thread. 

Thank you Konduru Chaitanya 

I have another doubt in above mentioned in total questions I hardcoded the question number for that how to fetch from database directly 

if you need to total number of questions, you can set the fetchTotalCount to true and get the result, for question number, you can use the counter or fv!index.

if you need to total number of questions, you can set the fetchTotalCount to true and get the result, for question number, you can use the counter or fv!index.
