Hi All,

* In initialize method i declared " reportContext.setPersistentGlobalVariable("i",new java.lang.Integer(0)); "
* I have incremented the value of " i " in On create method of 'Table detail Row'
* In Before Render method of a report i am calling the value of " i ". But the value is not incremented. Y it so...

But when i am accessing the value of " i " within table means i am getting its value.

My target is if the number of counts of a table row is '0' then i don't want to save the report document to my local disk else i have to save the document.

Please find the report in attachment.

hi,

The "Initialize" method is not a good place to define a persistent variable, because this event is fired twice: a first time when generating the document, and a second time on render. This is why your variable is correct when iterating within the table, and is reinitialized in beforeRender event.

You could declare a report variable and set its default value to 0 instead. See your example updated
