Tooltip for Textedit not persistent and does not display the entire text

Hello Experts,

I have a Page fragment with the below tag.

<htmlb:textEdit id="<%=l_id_note_display%>"

text="<%=l_note_change%><%=l_note_display%>"

width="100%"

rows="<%=Z_CL_BSP_HAP_DOC_CS_30=>C_NOTE_ROWS%>"

wrapping="HARD"

disabled="<%=l_disabled %>"/>

I have added tooltip to this tag as given below.

tooltip="<%=l_note_change%><%=l_note_display%>"

But the tooltip does not display the entire text in the text edit box. Also, the tooltip is visible for few seconds and then disappears. How do I overcome this issue?

Thanks,

Leena
