I have this spring macro

[@spring.formSingleSelect path="discoveryProjectDetailsBean.discoveryProjectBean.dataSource" options="dataSources" /]

it throws exception
freemarker.template.TemplateException: Expected collection or sequence. options evaluated instead to freemarker.template.SimpleScalar on line 227, column 20 in spring.ftl.
at freemarker.core.TemplateObject.invalidTypeException(TemplateObject.java:135)

this happens because it cannot interpret the dataSource list as sequence.

any help

    now I never found harder question that this, this exception above happened as the dataSource list I was trying to set as options list wasn’t pure string list. all the options list to be passed to the @spring.formSingleSelect I also found another reference here
    with a case just like mine code snippet of the working tag I am using now is below. 

    [@spring.bind "dataSources"/]     
[@spring.formSingleSelect "discoveryProjectDetailsBean.discoveryProjectBean.dataSource" dataSources "disabled='disabled' multiple='multiple' class='singleList' onchange='checkValidations()'" /]

    I hope this would help somebody
