Level 3 training Exercise 2 Process Transaction problem

Hi All,

In my process workflow the first activity I have is Invoke the System1_NavigateTo_WIDetails.xaml

I have an error message on my in_transactionItem value.

The error message is this


This is my process (to not get the answer)

First I need to work out where in_TransactionItem comes from

So in REFFramework I go to main → General Business Process → Process Transaction

In there is Invoke Process transaction workflow with input arguments in_Transaction coming from the variable TransactionItem

So now I need to find Transaction Item because maybe this is what doesn’t have the default value.

The TransactionItem variable is populated from main → General Business Process → Get Transaction Data

From the invoke GetTransactionData the out_TransactionItem argument populates the TransactionItem variable.

So do I have to put a Default value into the TransactionItem variable which is a DataRow type? If so what do I put and why do I have to put a default value.

Maybe that’s not the problem and the issue is in the GetTransactionData workflow.




GetTransactionData.xaml (11.1 KB)

Hey @charliefik,

Use in_TransactionItem.SpecificContent(“WIID”).ToString instead of in_TrasactionItem(“WIID”)
as you are getting the content from the queue item!

I’m a man on a mission :wink:

Ahh! Small problem


in_WIID is an int32.

Any chance your massive brain can solve that problem

You forgot the .ToString my man :wink:

So it can implicitly convert from string to in but not from object. Sorry about that

if this doesnt work try putting the whole thing inside Cint()

Doesn’t like that type of conversion either
Will do as you suggest Cint

Thats one less exclamation mark for the time being. Looking forward to creating many more thanks v much

I’ve changed the type of in_WIID from int32 to String inside the workflow to avoid using .ToString all the time , hence told you to do the .ToString, didn’t see you’re using int32!

Good thinking batman!

Hi Advanced people,

In my NavigateTo_WIDetails workflow I am getting compilation errors in my arguments, first one in in_WIID

The other one in System1_URL argument:

I’ve tried diffrent workarounds, but can’t find the solution, could you please help me to find out why?
