Stuck on the start form on the debugging process for the Acme exercise 8

Make sure you are assigning the rule input values to process variables use above screenshot for reference.

Thanks a lot for your reply,

Yes, I tried what you had suggested, the input text is ok now, but when I refresh to check if the information went through the process I get stuck again.

These are my variable in the start form:

I noticed, in the screenshot you shared, the value for the rule input vehicle only reads vehicle. 

when I use the expression editor to write = pv!vehicle. this is what I get. 

this is the error I get when I refresh to update the process flow

Can you pls guide on this. 

The assignment in the highlighted field should NOT read "=pv!vehicle". Make sure clear this field and just select the pv from the dropdown.

Your assignment means: "As the user submits, write the empty pv into itself!"

Your need to make it: "As the users submits, take the value from the forms rule input and store it into the pv!"

Hello Stefan

It doesn´t become available to select on the dropdown

How does It becames available to select? If I use the expression editor I have to write pv!vehicle. 

The data type of your rule input and PV should match.

How I make them match.. can you pls send a screenshot.

This is the rule input as type AA_veichle and array check is not selected.

Similarly, in the below screenshot the type of PV vehicle is AA_veichle and multiple is NO.

Configure these variables you will be able to select.

Hi!

thanks a lot for your kind support, and for taking the time to review. Unfortunately, I have the same as you sent me in the screenshot, but still, vehicle is not available to select on the process start form.

I would suggest you to try to use a new  variable but  create it by  clicking on the plus  simbol   beside the  column value   this new variable will have the same data type that your  interface needs  it could work

It didn´t work.

I got stuck on my learning path, seems I have everything the tutorial is telling me, already checked on the different possibilities. is there any error in the study material ? pls help! I don´t know how to fix the error.

An error occurred while trying to write to the entity "AX_Vehicle" [id=6d5c5950-65a2-4395-b56c-146a8b22e9f5@4749, type=AX_Vehicle (id=3542)] (data store: AX Data Store). Details: java.lang.IllegalArgumentException: The record to be saved must not be null: TypedValue[it=3542,v=<null>] Data: TypedValue[it=3542,v=<null>]

Try to clear the interface from start form and then replug it again when you will select the interface after that a dialogue box will appear select true and if your process variables are correct they will automatically match with your rule inputs.
