Declare variable from another variable in thymeleaf

Question

How declare a variable using another variable in thymeleaf? This is what I want to do:

<div th:with="var1='blablabla'">
    <div th:with="var2=${${var1} == null ? '' : 's'}">
       <span th:utext="${tmpCustomerType}">show var2</span>      
    </div>
</div>

but the compilator doesn't like that ${var1} :

EL1041E:(pos 1): After parsing a valid expression, there is still more data in the expression: 'lcurly({)'
(org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "${ccc} == null ? '' : ${ccc}" (custom:24))

Answer 1

You have bad el expression. Maybe these.

<div th:with="var1='blablabla'">
    <div th:with="var2=var1 == null? '' : 's'">
       <span th:utext="${tmpCustomerType}">show var2</span>      
    </div>
</div>
