Using xpath-expressions inside Task Instructions

[kc]

Hi all,

I have a process where I would like to build up the task Instructions in a string variable. However I cannot seem to resolve xpath values when I am putting my string as the task instruction.

How can I do this?

Thanks in advance

Sincerely

Kim,

You should be able to use the following notation:

Here are some instructions for {$/process_data/myvariable$}, please follow them.

Hi again Marcel - thanks for your quick reply

However I am not sure I und erstand your answer correctly.

I have a string variable (str_Inctructions) that I want to set as my Task Instruction.

So at a point in my process I create a set value with an expression like this:

str_Instructions = 'Here are some instructions for {$/process_data/myOtherVar$} please follow them.'

I then set str_Instructions as the Task Instructions (an xpath-expression). When I get the Task in Workspace I see the {$/process_data/myOthervariable$} instead of the value of myOtherVar.

So how can I get the value of myOtherVar?

Hi,

Please make sure that you have selected the task instruction type from literal to variable. It is a drop down on the right hand side.

Hi,

Please make sure that you have selected the task instruction type from literal to variable. It is a drop down on the right hand side.

And you can use the concatenation function in your setValue

str_Instructions = concat('Here are some instructions for ',/process_data/myOtherVar, 'please follow them.')

Or place the

'Here are some instructions for {$/process_data/myOtherVar$} please follow them.' in the task instruction and mark the instruction type as template.

What Marcel is saying is that it's easier to user the 'Template' option instead of a variable since you can type your text like a normal sentence with xPath expression embededd into it.

If you use a setValue and set a string, you need to concatenate the strings together using an expression like concat('Here are some instructions for',/process_data/myOtherVar, 'please follow them.').

Hi again all,

This works fine - I was just not aware that I needed top use the concat function to do gain this functionality.

Thanks a lot
