Controls in pageflows do not appear to be recieving lifecycle events in the
proper order
----------------------------------------------------------------------------------------
Key: BEEHIVE-1028
URL: http://issues.apache.org/jira/browse/BEEHIVE-1028
Project: Beehive
Type: Bug
Components: NetUI
Versions: V1
Reporter: Chad Schoettger
Assigned to: Chad Schoettger
So I have a small webapp which basically consists of a pageflow and a jdbc
control. The single jsp in the web app invokes an action in the page flow as:
<tr><td><img
src="doRenderChart.do?versionName=9.2Beta&projectName=Workshop&componentName=W-IDE&JFWidth=500&JFHeight=300"
border="0"/></td></tr>
It does this 10 or 11 times to build a table which contains images generated by
the action using the jdbc control to retrieve data from a database. Typically
(although not always) at least one of the images will not be generated due to
an SQL Error throw by the jdbc control. The error is that the SQLConnection
has been closed.
Here is a portion of the tomcat log, I've added some debugging statements in
the ControlContainerContext class to help me see what was going on, the
doRenderChart() is the page flow action being called by the jsp. It appears
the control's begin and end events are not fired in the right order, causing
(in some instances) the control to be unititialzed before a call has been
completed.
log4j:WARN Please initialize the log4j system properly.
