Read a View Context's node's element and assign from Component controller

[Former Member]

Hello Experts,

I'm new to JAVA WD.

Here is my scenario.

I have to use an Adobe form in a WDJ. The input parameters and the output parameters of the DC are defined in a method in the Interface Controller method.

The context of the Component Controller has the following structure

Context

---StartDate

---EndDate

---AbsenceType

Then the mapping between the Component controller and the interface controller is done so that the Interface controller also has the context structure as

Context

---StartDate

---EndDate

---AbsenceType

So now the interface controller and the component controller are bounded correctly.

Now I bind the view also with the Component controller as below.

Context

---StartDate

---EndDate

---AbsenceType

But since i need to use an Adobe interactive form inside this view, the datasource for the form cannot be the root context node but some other node. So I replicated the same structure in the view context so as to make the fields visible in the Adobe form context. Now the context looks as below.

Context

---StartDate

---EndDate

---AbsenceType

---DATA_NODE

-----StartDate

-----EndDate

-----AbsenceType

Now my question is, how do i map the result from the Adobe form into the context of the view??

What code should i write and where should i write to achieve this?

I need to do the following. But dont know how to write the code for this.

Context.StartDate = Context.DATA_NODE.StartDate

Context.EndDate = Context.DATA_NODE.StartDate

Context.AbsenceType= Context.DATA_NODE.AbsenceType

Please help!

Any help will be greatly appreciated.

Thanks,

Sam

Context.StartDate = Context.DATA_NODE.StartDate

Context.EndDate = Context.DATA_NODE.StartDate

Context.AbsenceType= Context.DATA_NODE.AbsenceType

wdContext.currentContextElement().setStartDate (
    wdContext.currentDATA_NODE().getStartDate());

wdContext.currentContextElement().setEndDate(
    wdContext.currentDATANODE().getEndDate()); // if it start date use that

wdContext.currentContextElement().setAbsenceType(
  wdContext.currentData_NODE().getAbsenceType());

Thanks a lot Nikhil for the swift response.

My requirement was a bit more different. Here the mapping are not within the same context but 2 different contexts as below.

InterfaceControllerContext.StartDate = ViewContext.DATA_NODE.StartDate

InterfaceControllerContext.EndDate = ViewContext.DATA_NODE.StartDate

InterfaceControllerContext.AbsenceType= Context.DATA_NODE.AbsenceType

Please let me know how I can access the Interface Controller nodes and attributes from within the implementation of the view at the press of a submit button. I don't want to do this by binding.

Thanks again for your help!

Go to view controllers properties page, under Required Controllers click on add button and add controllers you want.

If you graphically mapped view-component-interface controllers the values would have reflected in all.

Added Hints: Please not the order of execution is view.wdDoinit(), componentController.wdDoInit() and last execution is interface controller's init().

Thanks Nikhil for the info. But I cant do a graphical mapping here because the view context has to have the data elements inside a node and the CC and IC have the data elements directly on the context and there is no node. So I can't do a graphical mapping. I have to map the values through code dynamically.

Thanks Nikhil, using your code and doing some alterations to it, i got this thing working. So awarded full points.

Hello Nikhil,

I'm stuck with another small issue.

Let me first explain what I'm trying to do.

I have a view with the context structure as follows

Context

---DATA_NODE (Node)

----

---

Data1

----

---

Data2

---Data1

---Data2

All i need to do is, at the start of the view, i need to move the data from

Context.Data1=>Context.DATA_NODE.Data1 and

Context.Data2=>Context.DATA_NODE.Data2

Also, at the View Submit button click, I need to move the data from

Context.DATA_NODE.Data1 => Context.Data1 and

Context.DATA_NODE.Data2 => Context.Data2

(I managed to do this submit button click by calling an action->method and wrote the code as you gave earlier)

wdContext.currentContextElement().setData1(wdContext.currentData_NodeElement().getData1());

wdContext.currentContextElement().setData2(wdContext.currentData_NodeElement().getData2());

But I wrote at wdInit() for the view the code in the reverse way, but the values are not getting passed to the Data_Node and hence its not defaulting with the values from the elements of the context.

This is what I wrote.

wdContext.currentData_NodeElement().setData1(wdContext.currentContextElement().getData1());

wdContext.currentData_NodeElement().setData2(wdContext.currentContextElement().getData2());

Please let me know if I'm doing something wrong here.

Appreciate your help in advance!

Cheers,

Sam

Also, if i hardcode the value in the Init() method of the view its working.

wdContext.currentData_NodeElement().setStartData1("Hi");

But its not working if i assign it through code like this.

wdContext.currentData_NodeElement().setData1(wdContext.currentContextElement().getData1());

Please help!

Thanks,

Sam

seems unusual.

Are you sure that you have data in wdContext.currentContextElement().getData1() ?

check whether you are invalidating the node values before they get assigned?

yeah. The value is there.

And what do you mean by invalidating the node??
