Is it possible to call when condition in another when condition of different Applies To class
Hi All,
I have to call Work-. pzIsPerform when rule from Link-Attachment.HaveAttachmentDeletePrivileges when rule. Is it possible to call when rule in another when rule of different applies to class?
The original requirement is:
We have to enable the delete attachment button only in Perform harness and disable in other harness
Please help.
Thanks in Advance,

Hi, You can directly call the when condition by selecting the Rule[When] condition evaluates to true and you can call the when rule pzIsInPerform .Pls refer the screenshot.

Hi Deepak,
Thanks for the reply. I tried using this when condition. But, When the case is in Confirm harness, the below values in clipboard have different values and the pzIsInPerform returning true for confirm harness also.
Clipboard page values:
Declare_pyDisplay.pyDisplay(pxThread.pxPortal).pyUIActive(1).pyParameters.HarnessType=Confirm
Declare_pyDisplay.pyDisplay(pxThread.pxPortal).pyUIActive(1).pyParameters.HarnessPurpose=Perform
My doubt is, when the case is in Confirm harness why HarnessPurpose values is "Perform" in Clipboard?

Hi Sahul,
If your requirement is to call another when of different class, i am able make it work by calling a function by selection expression evaluates true in the when rule as below.
@evaluateWhen(MyWhen,"MyComp-xxx-Work-xxx",tools)
MyWhen- is the when rule name
Pass the class name as second parameter.
Hope it helps.
Thanks

Hi SreePriya,
Thanks for the response.
I tried using Work-pzIsPerform in Link-Attachment - HaveAttachmentDeletePrivileges as mentioned by you. But in the expression builder it is giving below compilation error as the pzIsPerform is internally calling one more when rule "pyIsHarnessTypePerform"
"Failed to find a 'RULE-OBJ-WHEN' with the name 'PYISHARNESSTYPEPERFORM' that applies to 'Link-Attachment'. There were 1 rules with this name in the rulebase, but none matched this request. The 1 rules named PYISHARNESSTYPEPERFORM defined in the rulebase are: 1 unrelated to applies-to class Link-Attachment, for example: Work-"

Hi Sahul,
Yes, evaluateWhen function gets the objclass of the passed when rule and tries executing it on the primary context itself. So, if there are any nested when rules in it, as it executes on the primary context and could not find the rule. To achieve this, the when rule execution should happen only on context of pxobjclass of when rule which is not the case here.
Cannot think of any OOTB way to achieve this nested scenario.
Thanks.
