Hi Again,
Attached is the reproducer (test.war).

please deploy this and call http://<host>:<port>/Test/test.do

You can see that we have here 4 tags (Test.jsp).
However the constructor is only called 1 time (org.apache.struts.taglib.html.TestTextTag).
Also the release is never called (Should be called after each tag ends to be compiled).
For your convenient i added system.out.println logs.

Also below is the should be JSP tag life cycle from(http://java.boot.by/wcd-guide/ch10.html):

Table 10.1. Tag Handler Methods

Tag Type	Interface	Methods
Basic	Tag	doStartTag, doEndTag
Attributes	Tag	doStartTag, doEndTag, setAttribute1, ..., setAttributeN , release
Body	Tag	doStartTag, doEndTag, release
Body, iterative evaluation	IterationTag	doStartTag, doAfterBody, doEndTag, release
Body, manipulation	BodyTag	doStartTag, doInitBody, doAfterBody, doEndTag, release


Hope this helps,
Roi

> When working with JSP tags on struts i can see that sometimes 2 diffrent tags with same type is called with the same instance.
> Example:
> JSP
>  <jcv:text id="email" maxlength="255" property="valueObject.Email"/>          
>  <br>
>  <jcv:text id="phone" maxlength="255" property="valueObject.Phone"/>
> TLD
> <tag>
>         <name>text</name>
>         <tagclass>tti.jcore.views.form.tag.JViewsTextTag</tagclass>
> ...
> </tag>
> I can see that the public int doStartTag() called for both with the same instance.
