javascript - GWT Application throws 'JavaScriptException' in IE only, stack trace has no helpful information -


my gwt application throwing javascriptexception @ point. issue occurs in internet explorer (both ie 8 , ie 8 running ie7 mode).

the stack trace follows:

com.google.gwt.core.client.javascriptexception: (error): invalid argument.  number: -2147024809  description: invalid argument. com.google.gwt.dev.shell.browserchannelserver.invokejavascript(browserchannelserver.java:195) com.google.gwt.dev.shell.modulespaceoophm.doinvoke(modulespaceoophm.java:120) com.google.gwt.dev.shell.modulespace.invokenative(modulespace.java:507) com.google.gwt.dev.shell.modulespace.invokenativeobject(modulespace.java:264) com.google.gwt.dev.shell.javascripthost.invokenativeobject(javascripthost.java:91) com.google.gwt.core.client.impl.impl.apply(impl.java) com.google.gwt.core.client.impl.impl.entry0(impl.java:188) sun.reflect.generatedmethodaccessor51.invoke(unknown source) sun.reflect.delegatingmethodaccessorimpl.invoke(unknown source) java.lang.reflect.method.invoke(unknown source) com.google.gwt.dev.shell.methodadaptor.invoke(methodadaptor.java:103) com.google.gwt.dev.shell.methoddispatch.invoke(methoddispatch.java:71) com.google.gwt.dev.shell.oophmsessionhandler.invoke(oophmsessionhandler.java:157) com.google.gwt.dev.shell.browserchannel.reacttomessages(browserchannel.java:1668) com.google.gwt.dev.shell.browserchannelserver.processconnection(browserchannelserver.java:401) com.google.gwt.dev.shell.browserchannelserver.run(browserchannelserver.java:222) java.lang.thread.run(unknown source)

debugging has been impossible least. google has told me property being set improperly (ie bad character setwidth("190px!")) or setting width 0px or else altogether.

since issue shows in ie, i've tried using ie developer tools debug, have come nothing.

how can go debugging properly?

this happened me , it's quite nightmare. proper usage of git/svn/cvs whatever saves here situation really, getting point "where worked" great. can now:

  • temporarily rid of custom css , see happens (leave plain default css gwt)
  • debug on external server, it's not slow then
  • try reproduce "certain point" , comment out related lines
  • inspect generated site (some firebug-like tool ie, hope such thing exists)
  • as suggested above, use pretty/detailed output style
  • reading generated javascript gwt never solved problem :( css related stuff or custom usage of dom gwt
  • get folks (or yourself) test various browsers on regular basis, it's nobrainer
