Sightly comparison expression

Hi,

How can we compare the two values in Sightly test condition. i tried with below code but not working.

Ex:

 <sly data-sly-list="${}" >
 <sly data-sly-test="${itemList.index == ${properties.getvalue} }">Show some text</sly>  

</sly>

Here "getvalue" is property name with type textfiled in a dialog, we want to display some text when list count is matching with getvalue.

    This is about the Sightly not casting to a different object-type.

    To convert the index, you can do this trick.

    data-sly-test.stringIndex="${'{0}' @ format=[itemList.index]}"

    data-sly-test="${ stringIndex == properties.yourProperty}"

    Two things seems to be wrong:

    1. data-sly-list="${}"  is empty, which should not be

    2. for comparison you can use ${itemList.index == properties.getvalue}"

    Please see these article to get these things clear..

    1. I have removed the code  in {} before posting to forum.

    2.. for comparison you can use ${itemList.index == properties.getvalue}"

     I am getting exception "

    Invalid types in comparison. Equality is supported for String, Number & Boolean types

    "

    I thought we should convert the values to one type. I tried with @ context = 'number' but not able to get output.

      Take a look at docs, it says its " Numeric text field that provides automatic keystroke filtering and numeric validation."

      Hi ,

      properties.getvalue will return string which cannot be compared with itemList.index which is integer. Hence you are seeing the exception

        also what property are you trying to compare with 

        it should be something like property.<propertyname> which returns integer
