episerver block not working with xforms -


i'm having problem getting xforms work in block in episerver 7. it's webforms , not mvc.

xforms works when put them on normal page, when use them on blocks null exception. see below.

description: unhandled exception occurred during execution of current web request. please review stack trace more information error , originated in code.  exception details: system.argumentnullexception: value cannot null. parameter name: virtualpath  source error:  unhandled exception generated during execution of current web request. information regarding origin , location of exception can identified using exception stack trace below.  stack trace:  [argumentnullexception: value cannot null. parameter name: virtualpath] system.web.virtualpath.create(string virtualpath, virtualpathoptions options) +11610798 episerver.web.templatecontrolloader.loadcontrol(httpcontextbase httpcontext, type rendertype, object renderdata, templatecontrol templatecontrol, string tag, action`2 binddataaction) +214 episerver.web.templatecontrolloader.loadcontrol(httpcontextbase httpcontext, icontentdata contentdata, templatecontrol templatecontrol, string tag) +223 episerver.cms.shell.movetoplatform.personalizationcontentcontrolresolver.resolvecontentcontrols(contentarea contentarea, control parentcontrol, string tag, string itemcssclass, string itemtagname, boolean enableeditfeatures) +870 episerver.web.propertycontrols.propertycontentareacontrol.getcontentrenderers(boolean enableeditfeatures) +598 episerver.web.propertycontrols.propertycontentareacontrol.createcontentareacontrols(boolean enableeditfeatures) +130 episerver.web.propertycontrols.propertydatacontrol.createchildcontrols() +103 system.web.ui.control.ensurechildcontrols() +182 episerver.web.webcontrols.property.createchildcontrols() +600 system.web.ui.control.ensurechildcontrols() +182 system.web.ui.control.prerenderrecursiveinternal() +60 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.control.prerenderrecursiveinternal() +222 system.web.ui.page.processrequestmain(boolean includestagesbeforeasyncpoint, boolean includestagesafterasyncpoint) +4201

i tried compare alloy templates, find no difference should break this.

i tried debug, doesn't stop @ break points give information.

anyone know problem be? thankful help.

i found solution problem, not why problem occured. guess episerver cached renderer , try access older version of did not exist.

solution renderer block seemed corrupt in way. did delete webcontrol renderer, enter edit mode , error "no renderer found block , create again.

so problem problem seems not have been xforms module.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
