I am having difficulty implementing some code that is supposed to find/create the path to a component for my application.

 - The cfcomponent is in the root directory.
 - the file that is calling it is in a directory called 'modules'


the code that is calling it is:
<!--- begin example code --->
<cfset paginationPath = reReplace(replace(getDirectoryFromPath(cgi.script_name), "/", ".", "ALL"), "(^\.|\.modules\.?$)", "", "ALL") />

<cfset       pagination = createObject("component", "#paginationPath#.Pagination").init() />
<!--- end example code --->


it generates the following error:
<!--- begin error example --->
   The name .Pagination is not a valid component name.
Component names cannot start or end with dots.
 
The error occurred in E:\CustomerData\webspaces\webspace_00104265\wwwroot\modules\E_WebUsers.cfm: line 132

130 :
131 : <cfoutput>
132 : <cfset       pagination = createObject("component", "#paginationPath#.Pagination").init() />
133 : </cfoutput>
134 :

<!--- end error example>




This code worked fine, in a previous example. I only changed the directory (as it was given in the example, by the developer) from 'examples' to 'modules' - but apparently, I have missed something else?

thanks for  you help

Well that means reReplace is returning an empty string for some reason.  

Sorry I can't answer your question, since it's really about a regular expressions (not CF). You you may want to add the regex topic to the tags to attract attention from the right experts. Since they may not know CF, I'd suggest outputting all of the paths/variables involved. It'll help you (and them) troubleshoot the problem:

<!--- get the result --->
<cfset paginationPath = reReplace(replace(getDirectoryFromPath(cgi.script_name), "/", ".", "ALL"), "(^\.|\.modules\.?$)", "", "ALL") />

<!--- display all variables --->
<cfoutput>
cgi.script_name = #cgi.script_name#<br>
getDirectoryFromPath(cgi.script_name) = #getDirectoryFromPath(cgi.script_name)#
##paginationPath##.Pagination = "#paginationPath#.Pagination#"<br>
</cfoutput>

Open in new window


Best of luck!

<cfset pagination = createObject("component", "#paginationPath#.Pagination").init() />

Open in new window

should be
<cfset       pagination = createObject("component", "#paginationPath#Pagination").init() />

Open in new window


On a side note you could also do
<cfset paginationPath = expandPath('./')>
