<div class="jive-rendered-content"><p>As we all know , many components in jbpm 5.30 final version is full of BUGs .After tremendous effort ,  I managed to solve all the bugs and can run the built-in evaluation process successfully in the gwt-console. Then I try to use the eclipse to develop a process which contains human tasks and the form (ftl) and   the upload them to the Guvnor , compile it and  use the gwt console to run this process.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><a class="jive-link-external-small" href="https://issues.jboss.org/browse/JBPM-3690">This stupid bug</a> causes my  task forms cannot be shown properly .  So I follow the stupid workaround to rename .ftl to .flt   before uploading to Guvnor using eclipse.  Then now , when I login in to the gwt-console and select the process. The following errors loop infinitely and will not stop .It causes the size of the size log grows continually indefinitely until the harddisk running of the space. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I don't know what happens and the exact ways to reproduce this problem .
