[Zope] How can I examine an property of an object from the other object in the other tree?

[이관수]

Forgive this nagging newbie.

But I am still at a loss and my question seems an eye-opening(at least partially) one for a newbie.

To restate my question,

The situation:
<!--#var isTRed--> just gives the *string* english.members.test.docTest.TR when called in the 
DTML Document /korean/members/test/docTest  not the *value* of english.members.test.docTest.TR (TR is a string property of docTest DTML Document).
So, it does not work.


Q0. Is there a way to force an evaluation of the string content of an variable?

Q1. <!--#var "isTRed"-->  gives me the source of isTRed method. Is this what you mean by "evaluated as an expression"?

Q2. If you mean using <!--#call --> tag by *call*, call tag gives nothing to the browser, doesn't  it?

Q3. <!--#var "isTRed()"--> gives the name error(Traceback is at the bottom), and it seems as expected since the valus of isTRed is just string.

Sorry for any vagueness in my writing. Reading/writing about naming, contents and behavior of OO system in English is far more difficult than I expected.
