Selenium fails to find component after dom update (reRender)
I'm using Fifefox 3.6.8, Selenium IDE 1.0.7, and RichFaces 3.3.1, running on Ubuntu Linux. I don't have this problem.
I have a simple form where the selection of a radio button triggers a reRender of an a:outputPanel. Initially, the panel is empty. If the right radio button is selected, the rendered condition is met, and the panel is rerendered with its children components. I am able to set a waitForCondition to look for an element id that will appear as a child of the panel, and I am able to verify the child elements after they appear. Selenium IDE correctly identifies these child elements when I right click in Firefox.
Selenium doesn't keep a cached version of the DOM. It can't because it is using JavaScript and all javascript DOM queries are always live.
What are you using to find the elements? If you are using Xpath/CSS selectors then there is a chance that the XPath is no longer valid or the CSS selector may not be correct.
