Value attributes into Model Node?

[Former Member]

Hi guys....

I faced with this "problem" a lot of times and I think that is very common....

Well, to explain better: You have an Model Node ( an Adaptive RFC Model for instance) . This node must to be used to populate a IWDTable, but you need to have another attributes ( like enabled, visibility, join attribute values, format some value, etc )....

Well, in the NW2004 the horrible workaround was create a Model Node into your context and add the "value attributes" BEFORE binding with the Model, but in 2004s ( or 7.0 ) it doesn't work... Another solution is create a value node with a similar structure ( plus the extra attributes ) and copy the values from the Model Node....

Is There another solution to solve this problems? I m thinking in create a JavaModel, that executes the RFCModel and provide the right structure, but some types of attributes ( visibility for example ) are View responsibility and not Model... Did I forget some part of the documentation ( from IWDNode, IWDTable or another one )???

Thanks a lot

Hi,

Create a model node and make a copy of created node. Now rename copied model node and add extra attributes. This is the easiest way to do.

Hi Alexander,

If you want value attributes under Model Node structure create a ValueNode under such ModelNode having 1:1 cardinality and keep all value attributes related to visibility or any calculated attributes under this 1:1 cardinality ValueNode.

How can i save values in this attributes?

for example, the result of RFC

nodeModel

- att1

- att2

- att3

- nodeValue

- att4

- att5

Modelnode is filled with several values (table), how can i fill nodeValue values within a loop??

for (int i = 0; i < wdContext.nodeModel().size(); i++)

{

???

}

Hi Christopher,

Try following code:

int leadSelection = wdContext.nodeModel().getLeadSelection();

for (int i = 0; i < wdContext.nodeModel().size(); i++)

{

wdcontext.nodeModel().setLeadSelection(i);

wdContext.currentValueElement().setAtt4("Att4 Value");

}

wdcontext.nodeModel().setLeadSelection(leadSelection);

I hope nodeValue has cardinality 1:1

Also make sure nodeValue has singleton property set to false.

Regards,

Gopal

Thx Gobal, works perfect.

Unfortunately i can't reward points in this thread

Hi Christopher,

Happy your problem got solved. Regarding Points, no problem buddy..

No need to change lead-selection. You can also do it like this:

for (int i = 0; i < wdContext.nodeModelNode().size(); ++i)
{
  IModelNodeElement e = wdContext.nodeModelNode().getModelNodeElementAt(i);
  e.nodeValueNode().setXYZ(...); /* access value node for this model node element */
}

One more question regarding this topic:

I use the ModelNode to show values in a table. This works perfectly with the addes valueNode.

But i have implement the TableFilter and here i get the error message "attributeInfo must not be null".

This results becauce the iterator of my sourceNode (my ModelNode) don't get the values in my valueNode!

my example

modelNode

- att1

- att2

- att3

valueNode

- att4

- att5

The iterator of my modelNode (which is created in TableFilter class) contains only 3 values!!

how can is solve that??

[Former Member]

Adapt the TableFilter class to take such subnodes into account.

Has anyone found a way to modify the TableFilter class to see these subnodes? I face the same problem and wanted to see if anyone solved it yet?

@Alexandre

Did you solve your problem? Want to do the same..

Hi,

By your post I understud that... you have a Model Node ( an Adaptive RFC Model for instance) with this you are populating a table and also you want to have some more attributes ( like enabled, visibility, join attribute values, format some value, etc ).... rigth?

under your Model Node (your Adaptive RFC Model) crate another Model node ( right click on RFC Model node -> new -> Model node) and in properties make "singleton" as "false" and then you can add Model Attributes as enabled, visibility like that.

This is the simplest way. and I worked on this a year back.

"Another solution is create a value node with a similar structure ( plus the extra attributes ) and copy the values from the Model Node.... "

I think this is a comfortable way doing that, don't know how to make that easier..

[nikhil_bose]

I didn't get your point exactly. From what I understood, you can make sub nodes within a model node where you can place value attributes and can have attributes with calculated property.
