    I'm a little late to the party, but I wanted to share a function that I'll often use for seeing if a user has a specific role:

    <#-- function: userHasRole
	Returns true if the user with the specified userId has been granted the role specified by testRole 
	param: userId - Number (not a string) corresponding to the user id of the user to obtain the setting data for
	param: testRole - String containing the name of the role
	return: true if the user has been granted the role, false otherwise
	usage: ${userHasRole(user.id,"Administrator")?string}
-->
<#function userHasRole userId testRole>
	<#if (userId)?? && userId?is_number && (userId gt 0) >
		<#attempt>
			<#list restadmin("/users/id/${user.id?c}/roles").roles.role as role>
			    <#if role.name?? && (role.name == testRole)>
					<#return true />
				</#if>
			</#list>
		<#recover>
			<#return false />
		</#attempt>
	</#if>
	<#return false />
</#function>

     Sample usage:

    <#if userHasRole(user.id,"Administrator")>
You're an admin!
</#if>
<#if userHasRole(user.id,"VIP")>
You're a VIP!
</#if>

Hi,

 

You can try this snippet

 

<#assign restStr = "/users/id/${user.id}/roles">
<#assign matchedRoles=[]>
<#assign userRoles = restadmin(restStr).roles.role>

 

<#list userRoles as role>
        <#assign matchedRoles=matchedRoles+role.name>
</#list>


<#if (matchedRoles?seq_contains("Group Creators") >
       <@component id="groups.widget.group-list-view"/>
</#if>

 

Hope this helps. If yes, please accept this as a solution. 

 

Thanks,
Premkumar

      Please check your code for the Syntax. Else share your code which I can have a look at.

        There is one additional parathesis. Try the below code. 

         

        <#assign restStr = "/users/id/${user.id}/roles">
        <#assign matchedRoles=[]>
        <#assign userRoles = restadmin(restStr).roles.role>
        <#list userRoles as role>
        <#assign matchedRoles=matchedRoles+role.name>
        </#list>
        <#if user.anonymous == false>
        <#if matchedRoles?seq_contains("Group Creators") >
        <@component id="groups.widget.group-list-view"/>
        </#if>
        </#if>
