java.lang.IllegalStateException: Illegal mismatching cell component id encountered during renderer encoding. Out of all rendered gridCell components encountered, the one whose index is 0 had an id="gc1" during the first processing visit but during the second processing visit, it had id="pgl2". This means that the application is using a panelGridLayout clientId="pt1:_d_reg:region0:1:pgl1" where it has rows and/or cells using either non-thread-safe or application logic-caused unstable "rendered" property assignment(s). The application developer must correct this issue.
