View Full Version : Liferay Portlet Using Extjs 3.0

6 Aug 2009, 4:10 AM

I'm developing portlets using extjs 3.0 for Liferay Portal.
So, when the portlet is rendered, the CSS of Liferay Portal seems to conflict with the CSS of Extjs, changing some features of extjs components.
Until now, the only way out that I found is to put a <Iframe> to separate the contexts of the Liferay and Exjs portlet. But with this "solution" I lost the possibility of use drag'n'drop beteen portlets and other features that are nedded to get the job done.
Anyone experienced something like this, and found a better solution?
Thanks and sorry for my bad English :)

I have started to look into this, but haven't gotten very deep yet at all. One question I have is are you using the concepts from the Application Layout Tutorial? I realize that by using this, it doesn't "scope" the css, but it might help you diagnose specifically if it is the css, or if its a javascript scope problem.
