how to work with When Condition?

Question

Hi there

1- Is is possible to assign more than one vlaue in VALUE for WHEN?

2- I want to set condition for WI in following order:

If Product A selected in Product Field then set Allow and Suggested Value to GlobalList -> Component A
If Product B selected in Product Field then set Allow and Suggested Value to GlobalList -> Component B
Else set Alow and Suggested Value to GlobalList -> Components

I made first and second step but I can not set the else condition to see correct behavior...

Any Idea?

<FieldReference refname="System.Common.Component">
  <WHEN field="System.Common.Product" value="Product A">
    <ALLOWEDVALUES>
      <GLOBALLIST name="Component A" />
    </ALLOWEDVALUES>
    <SUGGESTEDVALUES>
      <GLOBALLIST name="Component A" />
    </SUGGESTEDVALUES>
  </WHEN>
  <WHEN field="System.Common.Product" value="Product B">
    <SUGGESTEDVALUES>
      <GLOBALLIST name="Component B" />
    </SUGGESTEDVALUES>
    <ALLOWEDVALUES>
      <GLOBALLIST name="Component B" />
    </ALLOWEDVALUES>
  </WHEN>
</FieldReference>

Answer 1

I'm thinking the ELSE condition can be handed by defining that ALLOWEDVALUES rule outside of a WHEN clause. Then the ALLOWVALUES stays set to Globallist->Components, unless a WHEN clause takes over.

Hi Gregg 

Thank you for Replay

Actually I did as you suggest at first, The problem is that SUGGESTEDVALUES is working as expected, but after I add ALLOWVALUES just Else condition works.  
No Matter what I do ALLOWVALUES does not works.

Any Idea?

<FieldReference refname="Querix.Common.Component">
  <WHEN field="Querix.Common.Product" value="Product A">
    <ALLOWEDVALUES>
      <GLOBALLIST name="Component A" />
    </ALLOWEDVALUES>
    <SUGGESTEDVALUES>
      <GLOBALLIST name="Component A" />
    </SUGGESTEDVALUES>
  </WHEN>
  <WHEN field="Querix.Common.Product" value="Product B">
    <SUGGESTEDVALUES>
      <GLOBALLIST name="Component B" />
    </SUGGESTEDVALUES>
    <ALLOWEDVALUES>
      <GLOBALLIST name="Component B" />
    </ALLOWEDVALUES>
  </WHEN>
  <SUGGESTEDVALUES>
    <GLOBALLIST name="Components" />
  </SUGGESTEDVALUES>
  <ALLOWEDVALUES>
    <GLOBALLIST name="Components" />
  </ALLOWEDVALUES>
</FieldReference>

Maybe I am wrong. I don't think this can work.

The logic in your sample code is when select Product A, Allowed and Suggested items are items which are in both global list Component A and Components. This is an AND logic I think.

The only way I can think of is to specify all the Products in the WHEN condition.

Answer 4

In My Example When I select Product A or Product B, the component field shows empty list. But for other products i see list of Components.

Answer 5

That's correct. This is because when you select Product A, TFS will select the items which are both inside list Component A and Components. However, there is no one duplicate so the list shows empty. The same as Product B.

When you select other product, TFS will only use Components list.

I am sorry that we have no workaround for this issue right now. The only wayis to specify all the Products in the WHEN condition.
