I have a main-page portlet and several sub-pages portlet , they commnuicate via event mechanism , when i click one record in main-page , the mail-page will hide and all the sub-pages will be appear , it works well before , but today , i find that when i click one record in main-page , sometimes all sub-pages will appear and sometimes just part of them appear , so is there any method to help me do debug the issue and anyone had encountered the issue before ?
Thanks .
