DSM Error - java.lang.ClassNotFoundException- com.epicentric.taglib.html.LocalizedValueTag$ExtraInfo

Hi,

Getting class not found exception in WEM. 8.1 following the tag causing

java.lang.ClassNotFoundException: com.epicentric.taglib.html.LocalizedValueTag$ExtraInfo issue.

this was working fine in 8.0.X, this is happening only with region including two types in it. other regions are working fine.

<DSM:contentRegion name="TTBC-TMP-Header" scope="template"

types="TT_TextBlockComponent,MegaMenuComponent" />

any idea?

Is this DSM? Is the class referenced in the display view? It looks like a portal class so it should not be referenced in a DSM environment.

Yes this is DSM environment, my custom code doesn't have any reference to this.

When my contentRegion tag has two types then it is throwing java.lang.ClassNotFoundException- com.epicentric.taglib.html.LocalizedValueTag$ExtraInfo

<DSM:contentRegion name="TTBC-TMP-Header" scope="template"

types="TT_TextBlockComponent,MegaMenuComponent" />

From the stack trace, it looks like it is failing during the rendering of the component. Take a look at the view JSP that is configured to render the components that are in the region and see if they are referencing the epicentric class.
