Do I have to use "current" or "node" ?

[diegohs]

Hi everyone,

I can't comprehend at all how it works the prefixes in webdynpro.

I mean, sometimes we refer to: wdContext.nodeBapi... and sometimes to: wdContext.currentBapi...

What's exactly the difference between that ?

Thanks for your help ! and regards from Monterrey,Mexico.

wdContext.node<Something> refer to node, <b>collection of elements</b>, on lead selection path, wdContext.current<Something>Element refer to <b>single element</b> on lead selection path.

To understand lead selection path imagine path in tree hierarchy of WD context traversing back from any given element / node to selected element of its immediate parent node, then to selected element of grand parent etc till (always) selected element of root node (wdContext.currentContextElement).

Hi Valery,

It seems that you're the one in the webdynpro forum.. je.je

I asked this because I'm having problems trying to execute a FM. I can't set the input parameters! =(

Almost all bapis have single input parameters.. but this FM has a Structure as Input Parameter. I have tried almost everything.

FM example: Hriq_FM

FM import parameters(structure): Hriq_FM->Is_Student

Is_Student parameters: field1, field2, field3.

wdContext.currentIs_Student.setfield1("x");

wdContext.nodeIs_Student.currentIs_StudentElement.setfield1("x");

wdContext.nodeHriq_FM.nodeIs_Student.currentIs_StudentElement.setfield1("x");

But anything works.. =( Do you have any idea what should I check ?

Thaaaaanks a lot for your help, I have spend the last 2 days trying to do this.. =(

Regards,

Diego

Hi Diego,

Before you can set values in the fields of the structure you will have to create an element for that node because that node has a cardinality of 0:1 (from model binding).

Hence for the node corresponding to the structure create an element using the method wdContext.create<Structure Name>Element() method and then add using the set<Structure Name method>. This method has to be called on the node<Structure Name>() object.

Then you can set the values in the fields.

Hope this helps.
