Unable to bring up expression editor for Assign component 's source node

Question

Hi All,
I am a beginner in BPEL and trying to create a simple hello world BPEL process in my JDev 11.1.1.5.0
The screenshots in external tutorial does not match the Assign component window.
I started a new asynchronous SOA BPEL composite and then dragged an assign component in the middle of the recieveInput and callbackClient. Now I double clicked the Assign1 icon and get the "copy Rules" tab but I do not see any LOV in the top left which would have "expression" as a value as I want to concatenate the input string with "hello". I see a "Fx Calculator Icon" which I am supposed to drag to the target node but I can not drag it to the input node. Isn't possible to write an expression to the source node ?

Hi,
the assign activity changes a little bit between the versions of the JDeveloper. But we can figure it out, if you want to concatenate the input variable element and assign to the element of Output variable, what you can do is, drop an expression builder on the element of the output variable; then inside that expression builder you can use concat xpath function.
I beleieve in 11.1.1.3 version, if you want to append and assign to a target variable; we need to drop an assign activity, select copy operation; then select the expression as Type and write the concat expression in that window and on the right hand side, we need to select the variable for whome you want to assign the concatanated value.
Hope this helps,
