WebDesigner - Timer node


I have a problem with 'Timer' node using. Here is my Web Designer project:

Timer parameters: timeout in milliseconds - "5000", loop condition - "1=1" (also I have tried "true", "exists(...) " etc), Run asynchronously - unchecked, Execute immediately once - unchecked. Action7 popup: text - "Test 1". After that popup: text - "Test 2".

Loop condition doesn`t work in Timer. I expect that popup "Test 1" will append each 5 seconds and popup "Test 2" will not append. But I get only popup "Test 2".

I couldn`t find any examples in documentation or this forum about loop condition. Please assist.
