Does anybody know of reasons not to allow throwing a RRAIPE during onBeforeRender? Currently this is not possible but perhaps we should support it. Consider the following use case A Page with a LDM containing object x. The Page has a link to delete x from the database, after delete another Page is set as the responsePage. Now if the user clicks on the backbutton of the browser the LDM tries to reload object x from the database, which will not work because we just deleted it. So we detect this situation in the LDM#load method and throw a RRAIPE. The problem is since load is triggered from onBeforeRender it is caught by MarkupContainer#onBeforeRenderChildren() which is nice enoygh to let all WicketRuntimeExceptions pass unmodified but wraps every other Exception inside a WRE. The problem here is that RRAIPE is not a WRE.
Possible solutions are make AbortException extends WRE, make WRE an interface that is implemented by RRAIPE and modify the try-catch in MarkupContainer#onBeforeRenderChildren to also let the RRAIPE pass unmodified WDYT? Maurice
