That seems like an inordinate amount of code for just setting and returning
properties. I decided to play with the THIS scope, and came up with this:
<cfcomponent>
<cffunction name="init">
<cfset THIS.hasError = false>
</cffunction>
<cffunction name="mymethod">
<cftry>
<!--- some bad code --->
<cfcatch>
<cfset THIS.hasError = true>
</cfcatch>
<cftry>
</cffunction>
</cfcomponent>
Then in the calling page, I have this:
<cfobject component="cfc/mycfc" name="mycfc">
<cfinvoke component="#mycfc#" method="init">
<cfinvoke component="#mycfc#" method="mymethod">
<cfoutput>#mycfc.hasError#</cfoutput>
Am I doing anything illegal or bad there? I had heard that the THIS scope
was available outside the CFC, but I assumed that meant via the THIS scope,
which I found to be not true. Just trying to figure out if I might run into
a problem I'm not seeing by doing things this way.
Thanks,
Dan
