When you set or retrieve a value of a property, you can only set or retrieve it to or from a clipboard page. Most pages have an associated class and a name. The standard dot notation to reference a property is:
pagename.propertyname
This notation works for both source and target.
In most situations, you can use the keywords local, param, parent, primary, and top in place of an explicit page name. The keywords are not case-sensitive: Param.Width, PARAM.Width and param.Width all refer to the same parameter.
Notes:
It is not recommended that you use the Top
keyword in data transforms. There are situations where using Top
does not work if a top-level page is not clearly defined (for example, if a row has both source and target pages).
Note: You can use <CURRENT>
in declarative rules (specifically when there is a declarative target present).
To work with: |
Use this format |
A property on a named, top-level page. |
|
A property on the current Primary page. |
|
A property on the in-context page for children actions in a data transform , or for nested steps in an activity. For top level actions in a data transform, or top level steps in an activity, or any rule type that changes the Primary page when executed, this is equivalent to |
|
A parameter on the parameter page of an activity, data transform, or flow. (Technically, a parameter is not a property; no Rule-Obj-Property exists for it.) |
Param.myParameter |
A variable defined as a local variable on the Parameter tab of an activity form. (Technically, a local variable is not a property). |
Local.myParameter |
A property on an embedded page. |
myPage.myEmbeddedPage.myProperty |
The first element of a property of mode |
myPage.myEmbeddedPage.myValueList(1) |
The second element of a property of mode |
myPage.myEmbeddedPage.myValueList(2) |
The first element of a |
.myValueList(1) |
The element of a |
myPage.myEmbeddedPage.myValueGroup(MA) |
The first element of a |
myPage.myPageList(1) |
A property on the enclosing page of the current context, which is an embedded page. You can use this keyword twice to designate the grandparent page and so on. The In a Java step of an activity, the keyword You cannot use this keyword in data transforms. |
parent.theproperty parent.parent.parent.Loan(4).aproperty |
A property on the top-level page of the current context that is an embedded page, for a rule that includes a Pages & Classes tab. (When you use the |
top.theproperty top.myPageList(<current>).Rating For examples on using the <current> keyword, see Obtaining the current index of a page list or page group property |
A property on a page accessed through a linked property. Linked property references are useful in harnesses, sections, and flow actions. |
