Reproduction steps:

1. Start latest master bundle
2. Create a structure named "struct1"
3. Add a Separator to the structure
4. Add a Text field embedded into the Separator
5. Make the Text field repeatable
6. Add a template to "struct1"
7. Click on the Text field on the left, and its pattern will be inserted into the template
8. Save it and create a web content from "struct1"
9. Add 3 values to the repeatable Text field, save the content
10. Preview the content (eye icon in the "Default Template" section)

Actual result: an error is shown

An error occurred while processing the template.
Syntax error in template "20095#20122#34641" in line 2, column 73:
Encountered ".", but was expecting:
    ">"
1<#if Separatordtf8.Textaoqa.getSiblings()?has_content> 
2	<#list Separatordtf8.Textaoqa.getSiblings() as cur_Separatordtf8.Textaoqa> 
3		${cur_Separatordtf8.Textaoqa.getData()} 
4	</#list> 
5</#if> 

Expected: the values of repeatable Text field should be shown correctly. E.g.:

Text1 Text2 Text3

This is the generated FTL template:

<#if Separatordtf8.Textaoqa.getSiblings()?has_content>
	<#list Separatordtf8.Textaoqa.getSiblings() as cur_Separatordtf8.Textaoqa>
		${cur_Separatordtf8.Textaoqa.getData()}
	</#list>
</#if>

When the variable name doesn't contain "." character, it should look like this:

<#if Separatordtf8.Textaoqa.getSiblings()?has_content>
	<#list Separatordtf8.Textaoqa.getSiblings() as cur_Separatordtf8_Textaoqa>
		${cur_Separatordtf8_Textaoqa.getData()}
	</#list>
</#if>
