hi katts,
yes extval 1.1.x is for jsf 1.1.x implementations and extval 1.2.x is for jsf 1.2.x implementations. so your first try was ok. could you please provide a link to the demo which illustrates the constellation. regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/6/30 katts <srikanth_kongara@...>

hi katts,
the out-of-the-box functionality is quite easy to use. add the jar files to your project and use the annotations. how to use them is shown in the feature-set 01 example. the wiki describes basic concepts. more advanced examples are available at os890 (blog and google code project). if you add the lib to your project and you get an exception, we have to look into it. that's not due to a wrong setup (since the only setup step is to add the jar files). so there is no verbose documentation. it's just that simple... a jsfcentral article series provides some useful hints. (the next part is finished and will be online soon!) you can ask any question! if the answer isn't available so far, it will be added e.g. to the wiki. in view of your current issue we need at least the page-source you are using. a quick response will be possible, if you can provide a short demo which illustrates the constellation. otherwise i have to implement the demo myself since it might be an issue in combination with a special tobago component. regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/7/1 katts <srikanth_kongara@...>

hi katts,
a short addition: maybe we can avoid the demo - i created a small dev-add-on. you can find it at [1]. so please: 1) check it out 2) build it via maven 3) add the add-on (as maven dependency or just as jar file) to your project 4) start your project 5) navigate to the page where the exception occurs 6) you will get some output on the console -> send the output which is directly before the exception regards, gerhard [1] http://code.google.com/p/os890/source/browse/#svn/branches/java/web/jsf/extval/extval_dev/addon http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/7/1 Gerhard Petracek <gerhard.petracek@...> hi katts, |
