Image Map tag is inserted in middle of Input tag

[skalluraya]

Hi
I used JFree chart in many of my pages. But in one of my page, <map> tag generated by image map comes in middle of an input text box tag.
if i have give a input text like this
<input type="text" name="mytext" id="mytext"/>
then after image map is generated the input tag becomes like this

<input typ=""><map id="jfreechart-8511381151861076097.png" name="jfreechart-8511381151861076097.png">............</map>e="text" name="mytext" id="mytext"/>

so in html view i see some characters like
e="text" name="mytext" id="mytext"/>

What might be the problem.
