IllegalStateException - Cannot change configuration property 'visibility' to hidden

[ex70375]

hi isomorphic,

after upgrading from 4.1p_20140304 to 4.1p_20140311 i can't change the visibility of DynamicForm. i get this IllegalStateException.

Caused by: java.lang.IllegalStateException: Cannot change configuration property 'visibility' to hidden now that component isc_DynamicForm_0 has been created.

at com.smartgwt.sample.client.BuiltInDS.onModuleLoad(BuiltInDS.java:181)

For troubleshooting demonstration I have the following line added to the sample.

boundForm.setVisible(false);
