We have a link on a page that does a submit and pops up a new window once the form has been submitted.
The code is based on the PopupLinkSubmit example here: http://wiki.apache.org/tapestry/PopupLinkSubmit This all works fine on 4.0.2 but under 4.1.4-SNAPSHOT we get the following error when the page opens up: 2007-11-06 18:35:10,197, ERROR, [org.apache.tapestry.services.impl.HiveMindExpressionCompiler], line 227, Error generating OGNL statements for expression class with root {href=javascript:submitPopupLink('editorForm', 'PopupLinkSubmit','/GQ/Waiting.page');, [EMAIL PROTECTED]/editor.editorForm], class=action, popupLink=/GQ/Waiting.page, name=PopupLinkSubmit} org.apache.hivemind.ApplicationRuntimeException: Unable to add method void set(ognl.OgnlContext, java.lang.Object, java.lang.Object) to class $ASTProperty_116174fa4f8: [source error] put(java.lang.String,java.lang.Object) not found in java.lang.Object at org.apache.tapestry.enhance.ClassFabImpl.addMethod(ClassFabImpl.java:278) at org.apache.tapestry.services.impl.HiveMindExpressionCompiler.compileExpression(HiveMindExpressionCompiler.java:217) at ognl.OgnlRuntime.compileExpression(OgnlRuntime.java:523) at ognl.Ognl.compileExpression(Ognl.java:141) ...

The rendered versions of the link and the Javascript are the same as under 4.0.2 but we get the above error in the back end and the link does not work. We get a Javascript error stating that 'events' is null or not an object. This is referring to this line: form.events.submit(elementId); Which seems to be related to issues mentioned here http://tapestry.apache.org/tapestry4.1/usersguide/upgrade4.0.html Can anyone let me know what we should be doing instead of form.events.submit? The documentation does not make it clear what the replacement is If we fix the form.events issues will that also fix the error we see when the page loads up or is that an unrelated error?
