Question

I have a problem with PlayFramework 1.2.5 and my question is:

How can I use a variable that be assigned by a #set{…/} tag into a #{if …/} tag?

This is my java code – (it works):

...
renderArgs.put("blockInsert", true);
...

And this is my htm code – (it works):

...
#{set allowInsert:"${!blockInsert}" /}
...

Reading variables with ${} and #{get/} – (it works):

blockInsert == ${blockInsert}<br/>
allowInsert == #{get 'allowInsert' /}<br/>

Using variables on #{if/} tag – (it not works well):

using variable from renderArgs - (it works) 
#{if blockInsert}
    cant't insert
#{/if}
#{else}
    can insert
#{/else} 
<br/>

using variable from #{set} tag - (it not works) 
#{if allowInsert}
    can insert
#{/if}
#{else}
    cant't insert
#{/else}
...

When I run this page the output is:

blockInsert == true
allowInsert == false 

using variable from renderArgs - (it works) cant't insert 
using variable from #set} tag - (it not works) can insert 

Answer 1

use

%{allowInsert=!blockInsert}%

instead of set.
The Result of the set tag is a String. Or you adjust the if statement:

#{if allowInsert == "true"}
    can insert
#{/if}
#{else}
    cant't insert
#{/else}
