How do I escape ${} in my Tridion Component Template that is consumed by multiple templates?

Question

I am running into a situation where I have a fied with the value ${test}, in my component template that renders this the value comes out ok the problem comes in when another template calls this component and templates using @@RenderComponentPresentation(Component.ID, MyFirstTemplate)@@ at this point the ${test} is evaluated and because there is no such item on the component or in the package it evaluates to nothing.

• I have Component Template One that reads the value of a Component field (which contains: ${test})

  • This template renders fine, I get back "${test}"

• Now I have Component Template Two that calls @@RenderComponentPresentation(Component.ID, ComponentTemplateOne.ID)@@

  • This is where the ${test} now gets evaluated instead of retained so it goes from ${test} to "" because it doesn't find a variable or component field name with that name.

• Component Template Two then gets called by Component Template Three in the same way @@RenderComponentPresentation(Component2.ID, ComponentTemplateTwo.ID)@@

  • Since the ${test} has already been evaluated and lost in Component Template Two I no longer end up with ${test} I am still left with "".

I have tried:

• @@RenderComponentField('myField', 0, False, False)@@
• @@RenderComponentField('myField', 0, True, False)@@
• @@RenderComponentField('myField', 0, False, True)@@

no luck.

The following was my work around and it seems to work:

• Placing the "\" in front of both the open and close curly brace $\{test\}
• I need to make sure I remove the "\" after the last Template (Page or Component) executes.
• I have in place now a C# TBB that takes the "${test}" and does the following to it:
  • Converts the ${test} to $\{test\} in the initial template and a C# TBB on the Page Template that then returns it to the initial value of ${test}.

Is there a way to prevent this from happening or a way to avoid doing what i am doing to make this work?
