[jbosstools-issues] [JBoss JIRA] (JBIDE-9827) NPE occurs when edit big page

[Denis Golovin (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-9827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12634285#comment-12634285 ] 

Denis Golovin commented on JBIDE-9827:
--------------------------------------

There is a simple way to explain that null pointer exception and key line that is the reason for that is [line 334 in VpeVisualDomBuilder|https://source.jboss.org/browse/JBossTools/trunk/vpe/plugins/org.jboss.tools.vpe/src/org/jboss/tools/vpe/editor/VpeVisualDomBuilder.java?hb=true#to334]. This line drives UI events processing form UI thread and that triggers processing for source nodes which is not supposed to happen until control get out of VpeVisualBuilder. If line 334 is commented out null check is not required.
